Dual-Energy CT to Diagnose Occult Femoral Neck Fracture in MRI-Contraindicated Patient: A Case Report.

Case: A 79-year-old woman presented after a ground level fall with the inability to bear weight on her right hip. Radiographs and computed tomography (CT) imaging were negative for a femoral neck fracture. Her medical comorbidities precluded magnetic resonance imaging (MRI), so dual-energy CT with focused evaluation for bone edema was performed, identifying a femoral neck fracture that was stabilized surgically.

Implementation of a novel MRI protocol for diagnosing femoral neck fractures in high energy femoral shaft fractures: One year results.

Introduction: Preliminary results using a novel rapid-sequence MRI to diagnose ipsilateral femoral neck fractures in patients sustaining high-energy femoral shaft fractures have been favorable compared to radiographic and CT imaging alone. To evaluate and optimize this new institutional imaging protocol further, we reviewed our results one year after implementation.

Methods: Rapid-sequence MRI was added to the imaging evaluation of patients with high-energy femoral shaft fractures without femoral neck fractures identified on radiographs or CT imaging.

Herbal supplement usage among cancer patients: A questionnaire-based survey.

Background: Herbal supplements (HS) are one of the most commonly used complementary and alternative medicines in cancer. Reduced therapeutic efficacy of prescription anticancer agents through unwarranted herb-drug interactions is a major efficacy/safety concern. In view of the rising cancer prevalence in India along with a high degree of reliance and cultural acceptability in favor of traditional medicine drugs, prevalence data exclusively of HS usage during cancer treatment are of considerable epidemiological significance.

Assessment of a deep-learning system for fracture detection in musculoskeletal radiographs.

Missed fractures are the most common diagnostic error in emergency departments and can lead to treatment delays and long-term disability. Here we show through a multi-site study that a deep-learning system can accurately identify fractures throughout the adult musculoskeletal system. This approach may have the potential to reduce future diagnostic errors in radiograph interpretation.

Lung function of primary cooks using LPG or biomass and the effect of particulate matter on airway epithelial barrier integrity.

Background: Cooks exposed to biomass fuel experience increased risk of respiratory disease and mortality. We sought to characterize lung function and environmental exposures of primary cooking women using two fuel-types in southeastern India, as well as to investigate the effect of particulate matter (PM) from kitchens on human airway epithelial (HAE) cells in vitro.

Methods: We assessed pre- and post-bronchodilator lung function on 25 primary female cooks using wood biomass or liquified petroleum gas (LPG), and quantified exposures from 34 kitchens (PM, PM < 40 μm, black carbon, endotoxin, and PM metal and bacterial content).

Quantitative Assessment of In Vivo Human Anterior Cruciate Ligament Autograft Remodeling: A 3-Dimensional UTE-T2* Imaging Study.

Background: The timing of return to play after anterior cruciate ligament (ACL) reconstruction is still controversial due to uncertainty of true ACL graft state at the time of RTP. Recent work utilizing ultra-short echo T2* (UTE-T2*) magnetic resonance imaging (MRI) as a scanner-independent method to objectively and non-invasively assess the status of in vivo ACL graft remodeling has produced promising results.

Purpose/hypothesis: The purpose of this study was to prospectively and noninvasively investigate longitudinal changes in T2* within ACL autografts at incremental time points up to 12 months after primary ACL reconstruction in human patients.

Proteomic analysis of somatic embryo development in Musa spp. cv. Grand Naine (AAA).

Somatic embryos are comparable to their zygotic counterparts for morphological traits but are derived from somatic cells through various metabolic regulations, collectively referred as somatic embryogenesis (SE). It has been well exploited for germplasm conservation, genetic engineering, mutation breeding, for artificial seed technology and as a tool for mass multiplication. Though somatic embryo development is an important area of interest in growth, and developmental studies, the underlying molecular mechanism remains unclear.

Improving the Diagnosis of Ipsilateral Femoral Neck and Shaft Fractures: A New Imaging Protocol.

Background: Despite increased awareness of ipsilateral femoral neck fractures in patients with high-energy femoral shaft fractures and advanced imaging with thin-cut high-resolution computed tomography (CT), failure of diagnosis remains problematic. The purpose of the present study was to determine if the preoperative diagnosis of ipsilateral femoral neck fractures in patients with high-energy femoral shaft fractures can be improved with magnetic resonance imaging (MRI) compared with radiographic and CT imaging.

Methods: In response to delayed diagnoses of femoral neck fractures despite thin-cut high-resolution CT, our institutional imaging protocol for acute, high-energy femoral shaft fractures was altered to include rapid limited-sequence MRI to evaluate for occult femoral neck fractures.

Is the Cranial and Posterior Screw of the "Inverted Triangle" Configuration for Femoral Neck Fractures Safe?

Objectives: To determine the frequency where a posterior and cranial screw in a femoral neck that appeared contained on fluoroscopy violates the cortex.

Methods: Ten specimens including the hemipelvis with the proximal femur were obtained from unidentified embalmed specimens that were to be cremated after an institutional review board waiver was granted. Under fluoroscopy, the posterior and cranial screw of the inverted triangle configuration for the femoral neck was placed using standard technique with a cannulated 6.

The state of emergency radiology fellowships in North America and the development of a standardized curriculum.

Background And Objectives: The number of emergency radiology (ER) training programs in North America is small compared to the projected growth in demand for ER-trained radiologists. To date, there is no consensus-based training curriculum that sets a standard for all ER fellowship training programs. This study seeks to (1) identify the programmatic measures currently used in North American ER fellowship programs and (2) gather the perspectives of existing ER fellowship program directors (PD) and their recommendations for minimum and ideal curricular standards.

Emergency Magnetic Resonance Imaging of Musculoskeletal Trauma.

Musculoskeletal (MSK) trauma is commonly encountered in the emergency department. Computed tomography and radiography are the main forms of imaging assessment, but the use of magnetic resonance (MR) imaging has become more common in the emergency room (ER) setting for evaluation of low-velocity/sports-related injury and high-velocity injury. The superior soft tissue contrast and detail provided by MR imaging gives clinicians a powerful tool in the management of acute MSK injury in the ER.

POEMS Syndrome in a Juvenile Initially Diagnosed as Treatment Resistant Chronic Inflammatory Demyelinating Polyneuropathy.

POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, skin changes) is a disorder that mainly affects adults. We report a pediatric patient, initially considered to have Guillain-Barré syndrome, who continued to have progression of neuropathic disease leading to the diagnosis of chronic inflammatory demyelinating polyneuropathy. Diagnosis of POEMS was established by an abnormal bone marrow biopsy, prompted by laboratory and imaging findings, which became abnormal later in the course of the disease.

Research Priorities in the Utilization and Interpretation of Diagnostic Imaging: Education, Assessment, and Competency.
