In DCE-MRI of the prostate, a high temporal resolution (TR) is recommended. Nonetheless, no studies on the effects of TR on diagnostic accuracy of DCE-MRI of the prostate are available. In this study we examined the effect of TR of DCE-MRI on its diagnostic accuracy for detection of potentially malignant lesions. Our results indicate that TR>10s / timepoint leads to spurious perfusion estimates and therefore deteriorates the diagnostic accuracy for identification of potentially malignant prostate lesions.
