Answer

Answer

Abdominal or pelvic computed tomography (CT) scanning or magnetic resonance imaging (MRI) may reveal extracapsular extension, seminal vesical involvement, pelvic lymph node enlargement, liver metastases, and hydronephrosis (due to result of distal ureteral obstruction) in patients suspected of having locally advanced disease. Because the prostate-specific antigen (PSA) level does not always correlate with disease progression, repeat CT or MRI scans can help to determine the treatment response. [7]
