Observational StudyThe Association Between Use of Brain CT for Atraumatic Headache and 30-Day Emergency Department Revisitation.
The purpose of this article is to describe the association between initial CT for atraumatic headache and repeat emergency department (ED) visitation within 30 days of ED discharge. ⋯ After adjustment for clinical factors, we found that patients who underwent a brain CT examination for atraumatic headache at an initial ED visit were less likely to return to the ED within 30 days. Future appropriate use quality metrics regarding ED imaging use may need to incorporate downstream health care use.

Randomized Controlled TrialCan MDCT Unmask Instability in Binder-Stabilized Pelvic Ring Disruptions?
Pelvic binders may hinder radiologic assessment of pelvic instability after trauma, and avulsive injuries can potentially unmask instability in this setting. We compare the performance of MDCT for the detection of pelvic disruptions in patients with binders to a matched cohort without binders, and we assess the utility of avulsive injuries as signs of pelvic instability. ⋯ Evaluation for avulsive signs improves MDCT sensitivity for the detection of rotational instability but not vertical instability in patients with binders.

Accuracy of Liver Surface Nodularity Quantification on MDCT as a Noninvasive Biomarker for Staging Hepatic Fibrosis.
The purpose of this study was to investigate objective semiautomated measurement of liver surface nodularity on MDCT for prediction of underlying hepatic fibrosis (stages F0-F4). ⋯ Objective quantification of liver surface nodularity at MDCT allows accurate discrimination between stages of hepatic fibrosis, especially at more advanced levels. Although the results are comparable to those of elastography, this simple semiautomated biomarker can be measured retrospectively without additional equipment or patient time.

Comparative StudyFluoroscopically Guided Sacroiliac Joint Injections: Comparison of the Effects of Intraarticular and Periarticular Injections on Immediate and Short-Term Pain Relief.
The purpose of this study was to determine whether intraarticular sacroiliac joint injections provide greater immediate and short-term pain relief than periarticular sacroiliac joint injections do. ⋯ Although both intraarticular and periarticular sacroiliac joint injections provide statistically significant immediate and 1-week postinjection pain relief, no significant difference in the degree of pain relief achieved with intraarticular and periarticular injections was noted.

The objectives of the present study were to estimate the frequency of epipericardial fat necrosis among patients undergoing chest CT for chest pain and to compare the clinical and laboratory data between patients with epipericardial fat necrosis and control subjects. ⋯ Epipericardial fat necrosis is a significant clinical condition. For patients seen in the emergency department with isolated acute chest pain but no additional clinical history, no medication history, and normal laboratory results, chest CT is recommended to support a diagnosis of epipericardial fat necrosis.
