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.

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.

Observational StudyAbnormal Bone Marrow Signal Intensity in the Phalanges of the Foot as a Manifestation of Raynaud Phenomenon: A Report of Six Patients.
The objectives of our study were to describe the MRI findings of pedal phalangeal bone marrow edema in patients with Raynaud phenomenon (RP) and discuss the clinical implications of these MRI findings. ⋯ There is a progressive distal-to-proximal pattern of pedal phalangeal bone marrow edema on MRI in patients with RP. This knowledge may allow early diagnosis and treatment of rheumatologic disorders that are potentially associated with RP.

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.

CT plays a crucial role in the evaluation of stable patients with blunt and penetrating trauma in the emergency department. Among the more severe injuries that may occur in penetrating and blunt trauma are those to the inferior vena cava (IVC). The purpose of this study was to evaluate and differentiate the CT findings associated with penetrating versus blunt trauma to the IVC to aid the radiologist in diagnosing IVC injuries. ⋯ Injury to the IVC is frequently fatal in patients with penetrating or blunt trauma. The CT appearance of IVC injury is dichotomous between the two causes, with blunt IVC injury more likely to show extravasation, contour abnormality, and associated hepatic laceration. Injury of the retrohepatic IVC portends a poor outcome. With the continued use of CT for evaluation of trauma patients, the radiologist should be familiar with IVC injury and its different CT appearances.
