Correlation between adult trauma center status and radiology resident performance on trauma cases in the WIDI SIM exam.

Purpose: To assess whether adult trauma center status influences radiology resident performance on trauma cases in the Emergent/Critical Care Imaging SIMulation (WIDI SIM) exam.

Materials And Methods: This retrospective study analyzed 29,290 WIDI SIM exam scores from 110 adult trauma cases across 55 radiology residency programs. Residents were categorized by training level-R1 (n = 17,801), R2 (n = 9,136), R3 (n = 1,826), R4 (n = 527)-and by their program's adult trauma center designation: Level 1 (n = 20,121), Level 2 (n = 1,870), Level 3 (n = 1,029), Level 4 (n = 487), and no trauma designation (n = 5,834).

Challenges in diagnosis of calcaneal fractures: an examination using the WIDI SIM platform.

Introduction: The calcaneus is the most commonly fractured tarsal bone. Diagnosis is often challenging due to subtle radiographic changes and requires timely identification to prevent complications, including subtalar arthritis, neurovascular injury, malunion, osteomyelitis, and compartment syndrome. Treatment varies based on fracture type, with non-surgical methods for non-displaced stress fractures and surgical interventions for displaced or intra-articular fractures.

Comparison of metal artifact reduction using single-energy CT and dual-energy CT with various metallic implants in cadavers.

Objectives: The purpose of this study was to compare the effectiveness of metal artifact reduction using Single Energy Metal Artifact Reduction (SEMAR) and Dual Energy CT (DECT).

Materials And Methods: Six cadavers containing metal implants in the head, neck, abdomen, pelvis, and extremities were scanned with Standard, SEMAR, and DECT protocols on a 320-slice CT scanner. Four specialized radiologists blinded to acquisition methods rated severity of metal artifacts, visualization of anatomic structures, diagnostic interpretation, and image preference with a 5-point grading scale.

Fluoroscopically-guided therapeutic injection of the proximal tibiofibular joint in a patient with lateral knee pain.

Proximal tibiofibular joint (PTFJ) pathology is an uncommon but perhaps underappreciated cause of lateral knee pain. While imaging guided therapeutic injections for diagnosis and management of joint related symptoms are now commonplace and numerous techniques for accessing most joints in the body have been documented, a technique for fluoroscopically guided injection of the PTFJ has not been yet described in the literature. We present a case of an adult patient who presented with lateral knee pain refractory to conservative management who opted for a fluoroscopically-guided therapeutic injection of her PTFJ.

Current Concepts of Femoroacetabular Impingement.

Femoroacetabular impingement (FAI) is a prevalent clinical syndrome and likely a primary contributor to idiopathic hip osteoarthritis. It is characterized by osseous pathomorphology in the hip that alters normal biomechanics, causing accelerated joint degeneration and characteristic patterns of chondral and labral injuries. Early intervention in well-selected patients can provide symptomatic relief and delay progression to osteoarthritis.

Computed tomography-guided renal tumor biopsies: tumor imaging features affecting sample adequacy.

Objective: The aim of this study was to derive a model that predicts when a computed tomography (CT)-guided renal tumor biopsy will be diagnostic based on the tumor's unenhanced imaging characteristics.

Methods: The CT images used to guide percutaneous biopsy and the pathology reports of 276 consecutive patients undergoing renal tumor biopsy were retrospectively reviewed. The effect of tumor size, growth pattern, location, and CT attenuation on the diagnostic biopsy rate was assessed using univariate and multivariate techniques.

Treatment of infolding related to the gore TAG thoracic endoprosthesis.

The present report describes three cases of thoracic aortic endograft infolding or collapse involving the Gore TAG system. The cases include a penetrating aortic injury, a blunt aortic injury, and a symptomatic type B dissection. In the first case, infolding occurred in a delayed fashion after a normal-appearing 3-month follow-up computed tomographic angiogram.

Computed tomographic angiography for the diagnosis of blunt carotid/vertebral artery injury: a note of caution.

Objective: Computed tomographic angiography (CTA) by 16-channel multidetector scanner is increasingly replacing conventional digital subtraction angiography (DSA) for diagnosing or excluding blunt carotid/vertebral injuries (BCVI). To date there has been only 1 study in which all patients received both examinations. That study reported a high accuracy for 16-detector CTA.

Placement of intracranial pressure monitors: are "normal" coagulation parameters necessary?

Introduction: Patients with head injuries frequently have abnormal coagulation studies. Monitoring intracranial pressure (ICP) in head injured patients is common practice, but no best practice guidelines exist for coagulation parameters for ICP monitor placement.

Purpose: To test the hypothesis that hemorrhagic complication rates from ICP monitor placement are low and that the use of FFP to correct coagulation parameters to "normal" is not indicated.

Are automated blood pressure measurements accurate in trauma patients?

Background: Automated blood pressure (BP) determinations by oscillometry are reported to be as accurate as invasive monitoring for systolic pressures as low as 80 mm Hg. Automated BP devices are widely used by prehospital providers and in hospital operating rooms, emergency departments, and intensive care units, although the accuracy of automated BP has not been demonstrated in trauma patients. We hypothesized that automated BP is less accurate than manual BP in trauma patients.
