ACR Appropriateness Criteria Facilitate Judicious Use of CT Angiography for Stroke Workup in the Emergency Department.

Purpose: CT angiography (CTA) of the head and neck plays a key role in the evaluation of patients with stroke in the emergency department, particularly to evaluate for large-vessel occlusion and consider patients for mechanical thrombectomy. However, CTA is not always indicated and has various costs. The aim of this study was to examine the correlation between ACR imaging appropriateness recommendations and findings explanatory for stroke on CTA of the head and neck.

Automation of Educational Tasks for Academic Radiology.

Rationale And Objectives: The process of education involves a variety of repetitious tasks. We believe that appropriate computer tools can automate many of these chores, and allow both educators and their students to devote a lot more of their time to actual teaching and learning. This paper details tools that we have used to automate a broad range of academic radiology-specific tasks on Mac OS X, iOS, and Windows platforms.

Disappearing Acts: The Many Causes of Rapidly Destructive Arthritis.

Most of the destructive joint disease necessitating arthoplasty is the result of an insidious and protracted process that occurs over the course of many years. However, there are a variety of diseases that may result in a rapid progressive deterioration of a joint. We describe both the common and less common etiologies of rapidly destructive arthropathy that one should consider, with imaging examples, and present discriminative factors when present.

The use of vascular closure devices outside the catheterization laboratory after neurointerventional procedures is safe and effective: evidence from a retrospective study.

Purpose: To investigate the feasibility and safety of vascular closure device (VCD) deployment outside the catheterization laboratory.

Methods: Medical records were reviewed of all 799 patients (396 men; mean age 56 ± 16 years) who underwent deployment of 918 VCDs following diagnostic or therapeutic neurointerventional procedures over a 2-year period at 2 comprehensive stroke centers. The rates of major vascular complications in patients undergoing VCD deployment in and outside the catheterization laboratory were compared.
