The diagnosis of prostate cancer has increased with the widespread utilization of prostate specific antigen (PSA) screening. Imaging diagnosis is important in prostate cancer for making treatment decisions. Tumor staging directly affects treatment decision when curative treatment, such as radical prostatectomy, is an option. The tumor lesions in most prostate cancer cases are not feasible to detect on computed tomography (CT) scan. However, over the last decade imaging technologies have developed in many medical fields, in addition to urology, and imaging diagnostic equipment such as transrectal ultrasound (TRUS) power Doppler and contrast-enhanced, and magnetic resonance imaging (MRI) involving diffusion-weighted MRI and proton magnetic resonance spectroscopy, have shown promise for improving the detection and characterization of prostate cancer. This paper describes the recent improvements and future perspectives of prostate cancer imaging diagnosis with TRUS and MRI.
