Answer

Answer

Neither CT scanning nor MRI can be used to determine if lymph nodes are reactive or contain malignant deposits, unless the nodes are significantly enlarged and a percutaneous biopsy can be performed.

Despite the wealth of literature regarding the lack of use that imaging studies have in men with low-risk disease, more than one third of patients with low-risk prostate cancer in a SEER (Surveillance, Epidemiology, and End Results program)-Medicare analysis underwent imaging studies. [25]
