Comparison of 3T MR arthrography and 3T MRI in intra-articular hip pathology: a cost-analysis.

Background: MR arthrography (MRA) has previously been the radiological gold standard for investigating labral and chondral lesions of the hip joint. In recent years, 3T MRI has demonstrated comparable accuracy, being adopted as the first-line imaging investigation in many institutions.

Aims: We compare the associated increased cost and radiation dose of the fluoroscopic component of the MRA compared to MRI.

Are brake response times altered post CT-guided cervical spine nerve root injections?

Objectives: To assess if brake response times are altered pre and post CT-guided cervical spine nerve root injections.

Methods: Brake response times were assessed before and after CT-guided cervical spine nerve root injections in a cohort of patients. The average of 3 brake response times was recorded before and 30 min after injection.

Imaging of acute lower limb muscle injury and potential gender differences.

Objectives: To assess the most common lower limb acute muscle injuries on MRI imaging in a national specialist centre for orthopaedics and sports medicine and to explore potential gender differences.

Methods: Over a 3-year time period, all MRI lower limb studies with acute muscle injury (AMI) were reviewed. A British Athletics muscle injury classification (BAMIC) was given and a statistical analysis was performed.

Electric scooter-related triple cervical artery dissection.

A 34-year-old female presented to the emergency department with neck pain, dysphonia and dysphagia ten days after a fall from an electric scooter. Subsequent computed tomography of the neck revealed bilateral vertebral artery and unilateral internal carotid artery non-occlusive dissections, which were managed with antiplatelet therapy. This case describes mechanisms of injury, clinical presentation, imaging appearances, and subsequent management of cervical artery dissection.

Imaging of groin pain in athletes: patterns of injury at MRI and gender differences therein.

Aim: The purpose of our study was to review a large cohort of athletes of all levels presenting with groin pain who underwent investigation with MRI and to determine what the commonest patterns of injury were. We aimed to explore whether particular findings were commonly found in association and whether measurable gender differences exist in the incidence of specific injuries.

Materials And Methods: Imaging records were reviewed to identify MRI studies of the pelvis performed for the investigation of groin pain in patients who were active in sports/athletic pursuits.

Complications in image-guided musculoskeletal injections.

Complications in musculoskeletal interventions are rare and where they do occur tend to be minor, and often short-lived or self-limiting. Nonetheless, the potential for significant complications exists, and a thorough understanding of both the mechanisms which contribute and the manner in which they may clinically present is of critical importance for all musculoskeletal radiologists involved in performing procedures, both to mitigate against the occurrence of complications and to aid rapid recognition. The purpose of this review is to analyse the relevant literature to establish the frequency with which complications occur following musculoskeletal intervention.

Denervation pseudo hypertrophy of the calf: An important cause of lower limb swelling.

Denervation pseudohypertrophy is an uncommon cause of limb swelling, which may be overlooked. It is an important diagnosis to arrive at, as it instructs the search for an underlying cause which may itself require intervention. We present the case of a 32-year-old male rugby player with a 2-year history of left calf swelling and intermittent pain and tightness.

Voriconazole-induced periostitis post lung transplantation.

Voriconazole is a broad-spectrum triazole antifungal used to treat invasive fungal infections. It is commonly used prophylactically in immunocompromized patient cohorts, including transplant recipients. Diffuse periostitis is a very rare complication of chronic voriconazole use.

The Evolving Roles of MRI and Ultrasound in First-Line Imaging of Rotator Cuff Injuries.

Rotator cuff tears are the most likely source of shoulder pain in adults and may cause protracted disability. Management of rotator cuff tears is associated with considerable costs. Accurate diagnosis can guide surgical planning and help achieve a favorable clinical outcome.

Complications in image-guided musculoskeletal injections.

Objective: To establish the incidence and define the nature of complications occurring following image-guided musculoskeletal injections at our institution.

Materials And Methods: All patients undergoing image-guided musculoskeletal injection during the study period (16/3/2016 to 24/01/2020) were included. Departmental records were reviewed to identify all patients describing possible complications following injection, what therapy was required (if any) and what the outcome was.

Subperiosteal hematoma of the iliac wing presenting with leg weakness in a young adult footballer.

We present the case of a 17 year old football player with a 2 week history of left leg weakness and difficulty weight-bearing. Magnetic resonance imaging revealed a well-circumscribed lesion deep to the left iliacus muscle. The patient proceeded to computed tomography-guided biopsy.

Utilization and appropriateness in cervical spine trauma imaging: implementation of clinical decision support criteria.

Aims: To rationalize the ordering of trauma cervical spine radiographs via the institution of electronic clinical decision support criteria.

Methods: In February 2017, we added evidence-based criteria to the electronic imaging ordering system so that requesting clinicians had to indicate which criteria the patient met. We subsequently compared numbers of cervical spine trauma films requested by the ED in comparable months prior to and after the intervention.

Whole-body MRI of bone marrow: A review.

Technical advances in the last two decades have allowed rapid, high-resolution whole-body magnetic resonance imaging (WBMRI). MRI allows unparalleled visualization and detail in the imaging of bone marrow and surrounding soft tissues. The properties of nuclear magnetic resonance allow superb characterization of bone marrow constituents.

Role of Musculoskeletal Radiology in Modern Sports Medicine.

Musculoskeletal radiology's role in the recent and continued evolution of sports medicine is an exciting and expanding one. In this article we explore a variety of the ways that musculoskeletal radiology contributes to current practices in modern sports medicine, discussing advances across a variety of imaging modalities in the care of both elite athletes and so-called weekend warriors. We describe the technical and ethical factors pertaining to image-guided therapeutic intervention in athletes and speculate on the potential for future developments in the role of imaging in deciding when an athlete may return to participation.
