Purpose: Determination of quantitative T2 values in prostate tissue and their evaluation for detection and grading of prostate cancer.
Methods: 3T T2 maps and ADC maps of 75 patients with 857 prostate areas (378x normal, 177x cancer, 150x BPH, 119x prostatitis and 33x precancer) were determined.
Results: T2 values differed significantly between cancer and normal (AUC=0.871), between cancer and BPH (AUC=0.827) and between cancer with GleasonScore 6 and ≥ 7 (AUC=0.742). T2 relaxivities decreased with increasing GleasonScore and correlated significantly with ADC-values (r=0.772).
Conclusion: T2 values seem to be adequate for the differentiation between prostate cancer and normal tissue or BPH.
