Overview
On ultrasound, prostate cancer is characterized by hypoechoic areas.
Ultrasound
- On ultrasound, prostate cancer is characterized by hypoechoic areas[1]
- It seems that size of the area matters
- Small hypoechoic areas (<0.2 cm3) have cancer less than 4% of the time
- Transrectal ultrasonography (TRUS) is often initially performed in order to detect abnormalities and to guide biopsy, usually following an abnormal prostate-specific antigen (PSA) level or Digital rectal examination (DRE) result.[2]
- Transrectal ultrasound is also the modality of choice for directing brachytherapy seeds into the prostate gland.
Ultrasound may be helpful in the diagnosis of prostate cancer. Findings on an ultrasound suggestive of prostate cancer include:
- Hypoechoic lesion in the peripheral zone of the gland (60%-70%)
- Hyperechoic or isoechoic (30%-40%)
- Directing brachytherapy seeds into the prostate gland
