A Retrospective Multi-Site Academic Center Analysis of Pneumothorax and Associated Risk Factors after CT-Guided Percutaneous Lung Biopsy.

Purpose: To assess the risk factors, incidence and significance of pneumothorax in patients undergoing CT-guided lung biopsy.

Methods: Patients who underwent a CT-guided lung biopsy between August 10, 2010 and September 19, 2016 were retrospectively identified. Imaging was assessed for immediate and delayed pneumothorax.

Umbilical hernia simulating recurrent carcinoid on octreoscan.

Physiologic bowel activity on In-111 octreotide imaging is commonly seen. However, on occasion, normal bowel activity may mimic lesions in the abdomen, which can be very difficult to differentiate, particularly after surgical intervention. We report a case of focal bowel activity simulating a lesion in a patient who had an In-111 octreotide scan (Octreoscan), postoperatively, looking for recurrent carcinoid.

Online survey of radiologic ordering practices by pediatric trainees.

Objective: The ACR has developed appropriateness criteria to ensure that patients are receiving appropriate imaging studies. The purpose of this study was to compare the imaging ordering practices of pediatric residents in specific clinical scenarios with the ACR Appropriateness Criteria.

Materials And Methods: A multiple-choice questionnaire was created using 10 clinical scenarios excerpted from the ACR Appropriateness Criteria.

Prevalence and characterization of asymptomatic pacemaker and ICD lead perforation on CT.

Background: Pacemakers and implantable cardiac defibrillators (ICDs) are widely used for the management of cardiac arrhythmias and congestive heart failure (CHF). Acute implantation complication rates range from 3% to 7%. The aim of this study is to describe the incidence of lead perforation on computed tomography (CT), and correlate these findings with electrophysiologic data.
