Performance of PI-RADS v2 assessment categories assigned prior to MR-US fusion biopsy in a new fusion biopsy program.

Objective: To validate the performance of PI-RADS v2 for detection of clinically significant prostate cancer (csPca, Gleason ≥7) within the context of a new fusion biopsy program.

Material And Methods: Patients with a PI-RADS v2 assessment category assigned on pre-biopsy mpMRI between March 2015 and November 2017 were identified. Diagnostic performance of PI-RADS v2 was calculated using fusion biopsy results as reference standard using receiver operating characteristic curve analysis.

The Association Between Magnetic Resonance Imaging Disc Pathology and Provocative Discography at the Lumbar Level.

Objective: The objective of this study was to show that degenerative lumbar magnetic resonance imaging findings variably increase discography pain by level.

Methods: Lumbar discography and magnetic resonance imaging of 736 patients were retrospectively reviewed. Univariate/multivariate logistic regressions calculated the odds ratio (OR) (95% confidence interval, P < 0.

A Consistent, Reliable Landmark to Assist in Placement of Orbital Floor Reconstruction Plates After Blowout Fractures.

Objective: To define a reliable and consistent landmark, the superior posterior wall of the maxillary sinus, and to describe how this landmark can be used when repairing orbital floor fractures.

Methods: Retrospective chart review. Patients >18 years old diagnosed with unilateral orbital floor and/or zygomaticomaxillary complex fractures.

Positive Predictive Values of Lumbar Spine Magnetic Resonance Imaging Findings for Provocative Discography.

Purpose: The purpose of this study was to calculate the positive predictive value (PPV) of lumbar spine magnetic resonance imaging (MRI) findings for a painful disc using provocative discography.

Materials And Methods: Lumbar spine discography records and prediscography MRIs of 736 patients (2457 discs) who underwent discography for diagnostic purposes from 2003 to 2007 were retrospectively reviewed in an Institutional Review Board-exempt and Health Insurance Portability and Accountability Act-compliant protocol. Each level was identified as having high-intensity zone (HIZ) disc, disc protrusion, disc extrusion, or combination (any herniation type), disc bulge, disc degeneration, and spondylolisthesis.
