Prostate diffusion imaging with distortion correction.

Purpose: Diffusion imaging in the prostate is susceptible to distortion from B0 inhomogeneity. Distortion correction in prostate imaging is not routinely performed, resulting in diffusion images without accurate localization of tumors. We performed and evaluated distortion correction for diffusion imaging in the prostate.

MRI-Derived Restriction Spectrum Imaging Cellularity Index is Associated with High Grade Prostate Cancer on Radical Prostatectomy Specimens.

Purpose: We evaluate a novel magnetic resonance imaging (MRI) technique to improve detection of aggressive prostate cancer (PCa).

Materials And Methods: We performed a retrospective analysis of pre-surgical prostate MRI scans using an advanced diffusion-weighted imaging technique called restriction spectrum imaging (RSI), which can be presented as a normalized z-score statistic. Scans were acquired prior to radical prostatectomy.

Grading of posterior staphyloma with spectral-domain optical coherence tomography and correlation with macular disease.

Objective: To develop a novel grading system for posterior staphyloma imaged by spectral-domain optical coherence tomography (SD-OCT) and to correlate the incidence of macular disease (vitreomacular traction, epiretinal membrane, macular schisis, lamellar macular hole, and full-thickness macular hole) with each grade.

Design: Retrospective chart review.

Participants: A total of 150 eyes from 89 patients with posterior staphylomas were examined at Jules Stein Eye Institute, University of California Los Angeles.
