State-of-the-art imaging of prostate cancer.

Prostate cancer is the most common cancer in men. Modern medical imaging is intimately involved in the diagnosis and management of prostate cancer. Ultrasound is primarily used to guide prostate biopsy to establish the diagnosis of prostate carcinoma. Prostate magnetic resonance imaging uses a multiparametric approach, including anatomic and functional imaging sequences. Multiparametric magnetic resonance imaging can be used for detection and localization of prostate cancer and to evaluate for disease recurrence. Computed tomography and scintigraphic imaging are primarily used to detect regional lymph node spread and distant metastases. Recent advancements in ultrasound, multiparametric magnetic resonance imaging, and scintigraphic imaging have the potential to change the way prostate cancer is diagnosed and managed. This article addresses the major imaging modalities involved in the evaluation of prostate cancer and updates the reader on the state of the art for each modality.
