DWI is one of the evolving functional MR imaging that assess tissue cellularity,The ADC maps can provide quantitative measurements of tissue water diffusivity through ADC values. The Gleason scoring system has been accepted internationally as a reference grading system for prostate cancer with respect to tumor aggressiveness. Using the ADC values as a biomarker for assessment of prostate cancer aggressiveness may help appropriate management of this disease. In our study we included 30 patients with different prostatic lesions. All patients had a TRUS Biopsy with pathology analysis Found cancer,The prostate sampling technique is based on the sextant protocol, described by Hodge et al. , in which samples were obtained of the more peripheral zone (where the diagnostic yield is higher) from the base through the middle to the apex of the gland, bilaterally. Usually are 12 samples, two per Sextante ER -
