Ultrasonographic features of prostatic carcinoma

Area of Science:

• Urology
• Radiology
• Oncology

Background:

• Prostate cancer diagnosis relies on imaging techniques.
• Transabdominal ultrasound offers a non-invasive approach to visualize prostate anatomy.

Purpose of the Study:

• To evaluate the efficacy of transabdominal ultrasonography with tissue textural analysis in detecting prostate cancer.
• To compare ultrasound findings with histopathological results.

Main Methods:

• Performed 93 suprapubic transabdominal ultrasound examinations over 18 months.
• Utilized ultrasonographic tissue textural analysis to identify abnormalities.
• Correlated ultrasound findings with cancer detection and staging.

Main Results:

• Successfully identified 16 out of 19 prostate carcinomas.
• Detected focal abnormalities in the posterior or posterior-lateral prostate.
• Observed varied echogenicity (10 increased, 6 decreased) in carcinomas.
• Capsular irregularity was unreliable for determining capsular invasion.

Conclusions:

• Transabdominal ultrasound demonstrates potential for detecting prostate carcinoma.
• Computed tomography (CT) is recommended for evaluating the extent of cancer (staging).
