Ultrasound of the Prostate - Protocol. It plays an important role in most prostatic diseases. It is necessary for all prostate biopsies. If the PSA is elevated or increasing rapidly or there is an abnormal prostate examination then a transrectal ultrasound and prostate biopsy may be indicated to obtain tissue to make the diagnosis of prostate cancer. Transabdominal Ultrasound can assess the volume of the prostate but is not reliable to diagnose carcinoma.

Ultrasound is a widely used imaging modality for evaluation of the prostate. The main topic of diagnostic imaging is an improvement of prostate cancer diagnosis. The current available systematic prostate biopsy is performed only under ultrasound guidance, but new imaging techniques allow prostate cancer visualization and therefore improved detection.
Evolving methods such as contrast-enhanced colour Doppler imaging, contrast-specific ultrasound techniques and elastography may dramatically change the role of ultrasound for prostate cancer diagnosis. The purpose of this review is to provide an overview of ultrasound and its different techniques for imaging of the prostate and to discuss current trends and future directions. Ultrasound US is a widely used and well-tolerated imaging modality for evaluation of the prostate.
Recent technical advances in US applications have led to new aspects in the analysis of the prostate. Structural analysis is applied for measurement of prostate volume, study of echotexture, and illustration of tissue stiffness or elasticity. Functional analysis illustrates macrovascularity and microvascularity, which are indicators of tissue perfusion.
The purpose of this review is to provide an overview of the use of US imaging techniques and to discuss current trends and future directions. The prostate gland produces and secretes an alkaline fluid, which energizes and protects the sperm during ejaculation.
Commonly the prostate changes and enlarges with increasing age. Prostatitis, benign prostatic hyperplasia BPH , and prostate cancer PCa are the most common types of prostate disease. PCa is the most common malignancy in men [ 1 ]. Transrectal ultrasound TRUS is a widely used imaging modality for prostate evaluation. The advantages of TRUS over other modalities are low costs, good availability, and ability to visualize the prostate in real time.
Detection and delineation of prostate pathology with imaging remains a challenging endeavour. The prostate gland lies between the bladder neck and the urogenital diaphragm, just anterior to the rectum, an ideal position to be imaged via TRUS.
The gland is traditionally described based on a pathologic zonal architecture. These divisions consist of the anterior fibromuscular stroma that is devoid of glandular tissue, transition zone, central zone, periurethral zone, and peripheral zone. The prostate is further divided into apex and base directed upward to the inferior border of the bladder [ 2 ]. The neurovascular bundle courses bilaterally along the posterolateral aspect of the prostate and is a preferential pathway of tumour spread.
Prostatitis occurs at any age and its incidence increases with age [ 3 ]. Acute bacterial prostatitis often begins with chills and fever, lower abdominal discomfort, perineal pain and burning on urination. In chronic bacterial prostatitis when symptoms persist for at least 3 months perineal pain and increased frequency of painful voiding are the most common symptoms. The pathophysiology of prostatitis is not well understood. In patients with prostatitis, the activities of prostatic antibacterial factor are decreased and the pH is very alkaline.
Acute bacterial prostatitis appears in US as a hypoechoic rim around the prostate and colour Doppler shows an increased flow Fig. A prostate abscess appears sonographically as a hypoechogenic walled-off collection of fluid. In chronic bacterial prostatitis a diffuse increased enhancement of contrast agent may be found. US contrast agents show an increased perfusion of the prostate during acute and chronic infection, however they are not used in routine clinical practice since no studies regarding this issue have been performed [ 6 ].
BPH is a benign disease of the prostate gland and consists of nodular hyperplasia of the fibrous, muscular, and glandular tissue within the periurethral and transition zones.
The exact pathophysiology of BPH is still unknown but it is probably associated with hormonal changes that occur as men age. TRUS is mainly used to assess prostate volume, which is crucial for therapeutic strategies. Prostate volume can be estimated by serial planimetry, orthogonal plane, rotational body single plane, ellipsoid and three-dimensional methods.
Step-section planimetry is assumed to be the most accurate method of determining prostate volume, but it is time consuming and requires cumbersome special equipment.
One-dimensional measurements are preferable in the clinic. The prolate ellipsoid formula, multiplying the largest anterioposterior height , transverse width and cephalocaudal length prostate diameters by 0. PCa is the most common malignancy among men in western countries [ 1 ]. Furthermore, PCa is commonly asymptomatic at an early stage and most cancers are located in the peripheral zone.
Imaging plays a central role in the detection, localization and staging of patients who have PCa [ 6 ]. Since its introduction in transrectal grey-scale imaging has improved by application of higher frequency probes and new signal reception techniques.
The main use of grey-scale TRUS, however, is still the guidance of prostate biopsies. Nowadays, because of the low PSA cut-off values, PCa is detected at an earlier stage, and many cancer foci appear isoechoic, and therefore cannot be detected by grey-scale TRUS [ 8 ].
Since then many different protocols have been performed and nowadays at least 10—12 systematic biopsies of the peripheral zone are recommended as a first line strategy [ 9 ]. Oral or intravenous prophylactic antibiotics are state-of-the-art treatment. Optimal dosing and treatment time vary. Currently, quinolones are the drugs of choice, with ciprofloxacin superior to ofloxacin. The current consensus for local anaesthesia is the use of an US-guided peri-prostatic block.
It does not make any difference whether the depot is apical or basal. Intrarectal instillation of a local anaesthetic is clearly inferior to peri-prostatic infiltration [ 10 ]. As a result of PSA screening with low PSA cut-off values, a stage migration has occurred toward less aggressive, organ-confined cancer [ 9 ]. Three-dimensional TRUS aided in the assessment of extracapsular extension and seminal vesicle invasion [ 12 ].
Colour Doppler imaging is well established to illustrate macrovascularity and therefore perfusion. PCa has an increased microvessel density compared with healthy prostatic tissue. Therefore, Doppler visualization of streaming blood within the vasculature may aid in detecting and localizing PCa Fig. In addition, the cancer grade correlates positively with the degree of Doppler signal [ 13 ].
Corresponding contrast-enhanced colour Doppler US showing clearly more enhancement of the left side white ellipsoid. As a criterion for capsular penetration an increased capsular flow on colour Doppler imaging has been applied [ 2 ]. In addition, Doppler imaging also aids in differentiating fibrotic tissue from local recurrence of PCa [ 16 ]. Contrast-enhanced US can be used for illustration of macrovascularity and microvascularity [ 17 ].
These microbubbles can be used as an echo enhancer for US, leading to visualization of blood flow in the microvessels. New contrast agents are constantly being developed. Several different signal reception techniques can be applied for contrast agent detection such as cadence-contrast pulse sequencing CPS or microvessel imaging MVI technology.
The use of conventional Doppler imaging enhanced by microbubbles is the frequently reported in the literature. Frauscher et al. Two hundred and thirty male screening volunteers were included. CB in a patient with cancer was 2. CB detected as many cancers as SB with fewer than half the number of biopsy cores.
Mitterberger et al. The study included men and SonoVue Bracco, Italy was used. The Gleason score of all cancers detected by CB targeted biopsy was 6 or higher mean 6. The Gleason score of all cancers detected by SB ranged between 4 and 6 mean 5. CB detected significantly higher Gleason scores compared with SB.
Therefore CB techniques may allow identification of more aggressive cancers, which is important for defining prognosis and deciding adequate treatment. In another prospective trial from Innsbruck, the previous findings were confirmed. Moreover, the total detection rate for five targeted biopsies alone was higher than for 10 random biopsies Figs. Corresponding contrast-enhanced colour Doppler US showing clearly more enhancement of the right side white ellipsoid.
The development of contrast agent-specific US techniques have offered new potential for US in the detection of microvascularity, as found in the case of tumour vessels. These techniques use the non-linear properties of US contrast agents and therefore allow for a better axial and spatial resolution. First results by Halpern et al. In another study Halpern et al. Targeted biopsy cores were obtained from sites of greatest enhancement. PCa was found in Among subjects with PCa, targeted cores were twice as likely to be positive.
The authors concluded that the PCa detection rate of contrast-enhanced targeted cores is significantly higher compared with sextant cores. Contrast-enhanced transrectal sonography with IHI provides a statistically significant improvement in discrimination between benign and malignant biopsy sites. However, given the relatively low receiver operating characteristic areas, this technique may not be sufficient to predict which patients have benign versus malignant disease.
New ultrasound imaging techniques have been developed to better separate the information from bubble and tissue echoes. Cadence-contrast pulse sequencing CPS imaging is a low-power multipulse technique in which pulses with varied amplitude and phase are transmitted and the resulting echoes are summed.
This imaging sequence results in substantial tissue suppression, allowing detection of the presence of small numbers of contrast agents retained in tissue. In addition, CPS can be used at a low mechanical index to prevent bubble destruction, which is a requirement for serial imaging of targeted contrast agents.
By using CPS, certain sound sequences are transmitted that let the bubbles oscillate. The echoes of the contrast medium bubbles are separated from those of the tissue by using a special processing method.
Thus, the inflow of contrast medium can be witnessed real-time on screen [ 23 , 24 ]. Aigner et al. Transrectal CPS images were taken with a low mechanical index 0.
A microbubble contrast agent SonoVue, Bracco, Italy was administered as a bolus, with a maximum dose of 4. CPS was used to assess prostatic vascularity.
Disinfection of Probes An important aspect of patient safety is the disinfection of the ultrasound probes. How Ovarian Cancer Is Diagnosed. Prostate anatomy The prostate gland lies between the bladder neck and the urogenital diaphragm, just anterior to the rectum, an ideal position to be imaged via TRUS. Contrast-enhanced transrectal sonography with IHI provides a statistically significant improvement in discrimination between benign and malignant biopsy sites. A computer uses those sound waves to create an image.

An ultrasound exam or "sonogram" is a painless diagnostic technique that makes use of how sound waves travel through the body.
When sound waves pass through the body, they bounce off tissues and organs in certain ways. The reflected waves can be used to make images of the organs inside. The reason for the study and details of the case will help decide where the test should be done. In most cases, very little needs to be done before an ultrasound exam. The patient lies on the exam table. A clear, water-based gel is put on the skin over the part to be checked.
This gel helps the sound waves go through the body. A hand-held probe "transducer" is then moved over that part.
For prostate ultrasound exams, a specially designed probe is inserted into the rectum. Other exams, such as ultrasound of the kidneys, testicles or prostate, call for the user to have more experience or skill.
Ultrasounds can be used to look at different organs in the body. Below is a list of ultrasounds, Click on the link to learn more. Female urinary tract. The bladder is an organ made of smooth muscle. The most common reason for bladder ultrasound is to check bladder draining. The urine that remains in the bladder after urinating "post void residual" is measured. If urine remains, there can be a problem like:.
If you are not checking for post void residuals, a full bladder is needed. You may be asked to drink many glasses of water an hour before the exam. The exam is done as you lay on your back on the exam table. A gel is spread on the skin to help transmit the sound waves. The transducer is placed between your navel and pubic bone. The image is viewed on a monitor and read on the spot. When you return, the bladder will be imaged again. The kidneys are 2, fist-sized organs found on either side of your mid-section "retroperitoneum".
The kidneys remove waste from the blood and make urine. They also balance salts "electrolytes" in the body, such as sodium and potassium. Hormones that control blood pressure and red blood cell production are also made in the kidneys. Renal ultrasound studies can show the size and position of the kidneys. They can also show if there are:. A kidney ultrasound creates images from sound waves that return from the kidney tissue.
Many images are collected to understand problems in the kidney. If your doctor wants to see how blood flows to and from the kidney, Doppler imaging is used. This is an ultrasound method that makes color images from the movement of flowing blood.
It shows the flow of blood through the vessels. It provides excellent motion information not available on a standard sonogram. No need to fast, prepare your bowel, or have a full bladder. The test is done as you lay on your back on the exam table. The kidneys are imaged by placing the transducer over both sides of the upper belly.
A man's testicles testes are in a skin-covered muscular sac called the scrotum. The testicles make sperm cells for reproduction. They also make the male hormone, testosterone. The main reason for scrotal ultrasound is to check swelling or pain. It is common for fluid to collect around the testis. This is called a hydrocele, and is not cancerous. Other things like cysts in the epididymis " spermatocele " or large veins in the scrotum " varicocele " may be found.
This study can also be used to look at solid masses as a sign of testicular cancer. Testicular ultrasound is used to evaluate almost all issues in the scrotum, the sac containing the testicles. It can detect patterns from cancer, or if a mass is intratesticular, extratesticular, solid or cystic. It is used for testicular torsion, and problems with blood flow in the testis.
It can be used to prevent testicular death. For this test, Color-Doppler imaging is used. This high-quality color imaging has made testicular ultrasound an accurate and specific test. This test needs no preparation. It is done as you lay on your back on the exam table. The scrotum is raised onto a towel and warm gel is applied to help transmit sound waves. The transducer is moved over the area to create images.
The prostate is found at the base of the bladder in men. It circles the urethra like a napkin ring. The prostate makes part of the ejaculatory fluid, which is needed for reproduction. If the prostate gets large, it may block the bladder. The most common reason for a prostate ultrasound also called "transrectal ultrasound" is to check men who might be at risk for prostate cancer.
For this reason, a tissue sample " biopsy " of the prostate is also done. To diagnose prostate disease, your doctor will want to examine your prostate gland and nearby tissue. Prostate ultrasound can measure the volume or size of the prostate to help plan treatment. Patients receiving radioactive seed implantation "brachytherapy" to treat prostate cancer have transrectal ultrasound for this purpose. It is used to plan the number of seeds needed and where to place them.
This test may also be used to plan prostate surgery or other therapy such as thermal therapies. The study can measure prostate specific antigen density. Before this test, you may be asked to use an enema. During the test, you will lie on your side or back on the exam table. The ultrasound transducer probe is inserted into the rectum to see the prostate. The probe sends and receives sound waves through the wall of the rectum and into the prostate gland. These sound waves create images for diagnosis.
The urologist will look for signs of prostate cancer. At the same time, a small tissue sample may be taken for a biopsy. Local anesthesia may or may not be used with a biopsy. For a biopsy, a special needle is pushed through a channel on the transducer.
The biopsy is taken quickly. A number of biopsy "cores" are taken to be reviewed by a pathologist. There are relatively no risks from this test.
If you have a biopsy, you may feel limited discomfort. It can take many days to get the biopsy results. If cancer is found, your urologist will talk about treatment options. If the biopsy shows no cancer, your urologist will talk with you about plans for follow-up.
In some cases, transrectal ultrasound may be useful in finding abnormalities of the seminal vesicles and prostate. It can also be used to look at the testes.
