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]
- Ultrasound is used to direct biopsy of suspicious, hypoechoic regions, usually in the peripheral zone.
- Transrectal ultrasound is also the modality of choice for directing brachytherapy seeds into the prostate gland.
