PURPOSE: The purpose of this study is to determine the incidence of anterolateral ligament (ALL) tears on magnetic resonance imaging (MRI) in patients diagnosed with anterior cruciate ligament (ACL) tears. Furthermore, this study sought to determine the inter- and intraobserver reliability in diagnosing an ALL tear. METHODS: The MRI radiologic database at a community military hospital was queried for ACL tears over the period of January 2011 to April 2015. During this time, 181 MRIs were identified as having ACL tears...

OBJECTIVE: The purpose of this study is to identify the specialty characteristics of providers referring musculoskeletal (MSK) extremity imaging examinations to radiologists, so as to better understand the drivers of MSK imaging utilization and potentially improve the appropriateness of such imaging examinations. MATERIALS AND METHODS: Data on provider referral for MSK extremity imaging services were extracted from the 2014 Medicare Referring Provider Utilization for Procedures public use file, which aggregates data on diagnostic procedures according to referring provider identities and service codes...

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 Integrated 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...

Contact point (CP) trajectory is a crucial parameter in estimating medial/lateral tibio-femoral contact forces from the musculoskeletal (MSK) models. The objective of the present study was to develop a method to incorporate the subject-specific CP trajectories into the MSK model. Ten healthy subjects performed 45 s treadmill gait trials. The subject-specific CP trajectories were constructed on the tibia and femur as a function of extension-flexion using low-dose bi-plane X-ray images during a quasi-static squat...

OBJECTIVES: The aim of this pictorial review is to illustrate the use of CBCT in a broad spectrum of musculoskeletal disorders and to compare its diagnostic merit with other imaging modalities, such as conventional radiography (CR), Multidetector Computed Tomography (MDCT) and Magnetic Resonance Imaging. BACKGROUND: Cone Beam Computed Tomography (CBCT) has been widely used for dental imaging for over two decades. DISCUSSION: Current CBCT equipment allows use for imaging of various musculoskeletal applications...

PURPOSE: MRI and ultrasound (US) are effective diagnostic tools to evaluate extremities. In this study, we analyze utilization trends in musculoskeletal (MSK) US and MRI from 2003 to 2015 within the Medicare population. METHODS: Our data sources were the Medicare Part B Physician/Supplier Procedure Summary Master Files for 2003 to 2015. They cover all Medicare fee-for-service enrollees (37.5 million in 2015). Current Procedural Terminology codes for nonvascular, nonspine joint MRI and extremity US were selected and volumes within these codes were determined...

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...

PURPOSE: To evaluate the safety of withholding preprocedure international normalized ratio (INR) and platelet testing in patients undergoing musculoskeletal (MSK) core needle biopsy (CNB). MATERIAL AND METHODS: Initially, a retrospective review of 1,162 consecutive patients undergoing MSK CNB with preprocedural INR and platelet testing was performed. Clinical (age, gender, bleeding disorder, liver disease, anticoagulation use, INR > 2, platelet count <50,000/ul) and biopsy factors (imaging modality, lesion type, biopsy needle gauge, number biopsy samples) were tested for association with bleeding complications...

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...

AIM: To investigate image interpretation performance by diagnostic radiography students, diagnostic radiographers and reporting radiographers by computing eye gaze metrics using eye tracking technology. METHODS: Three groups of participants were studied during their interpretation of 8 digital radiographic images including the axial and appendicular skeleton, and chest (prevalence of normal images was 12.5%). A total of 464 image interpretations were collected. Participants consisted of 21 radiography students, 19 qualified radiographers and 18 qualified reporting radiographers who were further qualified to report on the musculoskeletal (MSK) system...

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...
