Comparing diagnostic accuracy of luminal water imaging with diffusion-weighted and dynamic contrast-enhanced MRI in prostate cancer: A quantitative MRI study.

Luminal water imaging (LWI) is a new MRI T mapping technique that has been developed with the aim of diagnosis of prostate carcinoma (PCa). This technique measures the fractional amount of luminal water in prostate tissue, and has shown promising preliminary results in detection of PCa. To include LWI in clinical settings, further investigation on the accuracy of this technique is required.

Luminal Water Imaging: A New MR Imaging T2 Mapping Technique for Prostate Cancer Diagnosis.

Purpose To assess the feasibility of luminal water imaging, a quantitative T2-based magnetic resonance (MR) imaging technique, for the detection and grading of prostate cancer (PCa). Materials and Methods Eighteen patients with biopsy-proven PCa provided informed consent to be included in this institutional human ethics board-approved prospective study between January 2015 and January 2016. Patients underwent 3.

MR measurement of luminal water in prostate gland: Quantitative correlation between MRI and histology.

Purpose: To determine the relationship between parameters measured from luminal water imaging (LWI), a new magnetic resonance imaging (MRI) T mapping technique, and the corresponding tissue composition in prostate.

Materials And Methods: In all, 17 patients with prostate cancer were examined with a 3D multiecho spin echo sequence at 3T prior to undergoing radical prostatectomy. Maps of seven MR parameters, called N, T , T , A , A , geometric mean T time (gmT ), and luminal water fraction (LWF), were generated using nonnegative least squares (NNLS) analysis of the T decay curves.
