PURPOSE: Genomic profiling of biopsied tissue is the basis for precision cancer therapy. However biopsied materials may not contain sufficient amounts of tumor deoxyribonucleonic acid needed for the analysis. We propose a method to determine the adequacy of specimens for performing genomic profiling by quantifying their metabolic activity. METHODS: We estimated the average density of tumor cells in biopsy specimens needed to successfully perform genomic analysis following the Memorial Sloan Kettering Intregrated Mutation Profiling of Actionable Cancer Targets (MSK-IMPACT) protocol from the minimum amount of deoxyribonucleonic acid needed and the volume of tissue typically used for analysis...

Metabolic perturbations in diabetes mellitus affect various organ systems and can lead to end-organ failure. Though most musculoskeletal (MSK) complications of diabetes mellitus are usually not life-threatening, they are often the cause of significant morbidity. While some of the MSK complications have a proven association with diabetes mellitus, others have been loosely associated because of their frequent coexistence, as are the rheumatologic complications. While many of these conditions are well-known, some are overlooked in routine clinical practice...

Dual energy computed tomography (DECT) is a constantly evolving technology, which opens up new diagnostic possibilities. It is particularly valuable for musculoskeletal (MSK) imaging. Due to the lack of recognition and availability of dual energy scanners, routine use is only established in a few centres. The intention of this review is to show the possibilities and fields of applications of the DECT in MSK imaging, as well as to describe technical principles and typical indications. We mainly focus on the use of DECT in the context of fragility fractures of the pelvis...

The article reviews the major challenges related to the principles of the correct technique of musculoskeletal ultrasound (MSK US). All the crucial aspects of correct MSK soft tissue diagnosis have been discussed, including equipment settings, use of recent image software innovations and ultrasound standoff pads, and correct transducer positioning. The importance of the fundamental principles of MSK US, facilitating good quality image and limiting the occurrence of artifacts, has been highlighted. The most common artifacts of the musculoskeletal system have been described, including those that diagnostically helpful, such as the presence of echo enhancement deep to a fluid-filled structure, or an acoustic shadow behind a calcification...

INTRODUCTION: Public expectations regarding access to the emergency department (ED) challenges providers and policy makers with finite resources being stretched beyond capacity. To enable education of a greater numbers of doctors the format of the medical internship in Australia has changed and assumes that sufficient supervision is provided to interns to enable image interpretation skills development. Furthermore this assumes that appropriate foundational skills are established during undergraduate education...

Background Soft-tissue chondroma (STC) is a rare benign soft tissue tumor that arises primarily in acral extra-skeletal locations. Occasionally, STCs may arise in more proximal non-acral locations, accompanied by non-classic features that label them as indeterminate lesions and pose diagnostic challenge for both radiologists and pathologists alike. Purpose To explicate the potential of diagnostic imaging in the identification and characterization of appendicular non-acral STCs with emphasis on their morphologic magnetic resonance imaging (MRI) enhancement...

OBJECTIVE: The aim of our study is to demonstrate that increased T2 signal on MRI could be due to intraneural vessels in asymptomatic individuals, and may therefore be a normal finding. METHODS: An initial anatomic cadaveric study was undertaken to gain a better understanding of the vascular supply of the proximal sciatic nerve. Secondly, a retrospective study of MR imaging of patients without sciatic symptoms was performed to assess the prevalence of intraneural vessels, defined as hyperintensity on at least three consecutive slices on both T2 and gadolinium enhanced T1 weighted imaging, visible on routine MSK pelvic imaging...

Tophaceous gout is painful and impairs quality of life. The optimal modality for assessing tophus resolution in response to urate-lowering treatment remains poorly defined. Using pegloticase as a model system for resolving tophi, we compared multiple imaging and physical diagnostic strategies for assessing tophus resolution. A 32-year-old subject with chronic refractory tophaceous gout was enrolled and received 6 months of pegloticase treatment. Measurements of tophi using vernier calipers (monthly), photographs and musculoskeletal ultrasound (MSK-US; every 3 months), and dual-energy CT (DECT) were compared...
