The role of magnetic resonance imaging in prostate cancer staging with newer imaging techniques

Abstract

Purpose: To prospectively evaluate which technique among T2 weighted images, Dynamic Contrast Enhanced (DCE) or Diffusion Weighted (DW) MRI or combination of those is best suited for prostate cancer detection and local staging. Materials & Methods: Twenty seven consecutive patients with biopsy proven adenocarcinoma of the prostate underwent MR imaging on a 1,5T scanner with a surface phased-array coil prior radical prostatectomy. Combined anatomical and functional imaging was performed with the use of T2 sequences, DCE and DW MRI. We compared the imaging results with whole mount histopathology.Results: For the multiparametric approach, significantly higher sensitivity values, ie, 53% (95% CI: 41-64.1) were obtained as compared to each modality alone or any combination of the three modalities (P < 0.05). The specificity for this multiparametric approach, being 90.3% (95% CI: 86.3-93.3) wasn’t significantly higher (P < 0.05) as compared to the values of the combination of T2+DCE, DWI+DCE ...
