Synopsis

Keywords: Cancer, Head & Neck/ENTWe hypothesize that RDC is useful for image quality and diagnostic performance improvements on DWI with b value at 1500 s/mm² in suspected prostatic cancer patients, although there was little influence of RDC on DWI at in vitro study. The purpose of this study was to determine the influence of RDC for ADC measurement at in vitro study and its’ utility for improving image quality and diagnostic performance of malignant from benign head and neck tumors on DWI as in vivo study.
