Concordance Assessment of Pathology Results with Imaging Findings after Image-Guided Biopsy.

Purpose: To assess the impact of radiology review for discordance between pathology results from computed tomography (CT)-guided biopsies versus imaging findings performed before a biopsy.

Materials And Methods: In this retrospective review, which is compliant with the Health Insurance Portability and Accountability Act and approved by the institutional review board, 926 consecutive CT-guided biopsies performed between January 2015 and December 2017 were included. In total, 453 patients were presented in radiology review meetings (prospective group), and the results were classified as concordant or discordant.

Pancreatic atrophy in patients with chronic graft-versus-host disease.

Purpose: To determine if patients with chronic graft-versus-host disease (cGVHD) following allogeneic hematopoietic stem cell transplantation (HSCT) develop greater loss of pancreatic tissue than patients without cGVHD.

Materials And Methods: This is an IRB-approved, HIPAA-compliant retrospective study of patients receiving allogeneic HSCT at our institution from 01/2006 to 01/2010 with abdominal CT performed within 3 months prior to HSCT and CT performed at least 3 months after HSCT. Measurement of glandular tissue thickness of the head, body, and tail of the pancreas was performed independently by two radiologists blinded to clinical data.

Embolization therapy for benign prostatic hyperplasia: influence of embolization particle size on gland perfusion.

Purpose: To assess the influence of embolic size on the therapy response of prostatic arterial embolization (PAE) based on perfusional changes seen on dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI).

Materials And Methods: Twelve beagles underwent PAE, four dogs with each particle size: A: 100-300 μm; B: 300-500 μm; and C: 500-700 μm. Prior to and 1 month after the embolization all dogs underwent prostate DCE MRI.

Quality initiatives: strategies for anticipating and reducing complications and treatment failures in hepatic radiofrequency ablation.

Radiofrequency (RF) ablation is one of several local treatment strategies that can be used for the destruction of a variety of primary and secondary liver tumors. As experience with RF ablation grows, it becomes increasingly evident that successful ablation requires meticulous technique. In addition, knowledge of potential complications is critical for both the interventionalist and the radiologist, whose postablation interpretation can facilitate identification of complications and treatment failures.
