This study reveals that the distribution of low intensity area in the peripheral zone of prostate may change and even the focal low intensity area mimicking prostatic cancer may appear and disappear on the repeated T2 weighted MR imaging even in the patients without clinically significant prostatic cancer. Radiologists should know the non-cancerous low intensity area in the peripheral zone can vary on the repeated MR examination and sometimes these low intensity areas might mislead the diagnosis.
