Lumbar spine abnormalities and facet joint angles in asymptomatic elite junior tennis players.

Background: Lumbar spine abnormalities, in particular stress fractures to the pars interarticularis, are common in elite junior tennis players, though the difference in prevalence between males and females remains unclear. Further, facet joint orientation appears to be a possible option for recognizing which players might go on to present with a pars stress fracture. Given the link between pars stress fractures and low back pain in tennis players, it appears logical to explore the link between facet joint angle and pars abnormalities.

Use of computed tomography and magnetic resonance imaging for occult neck of femur fractures: A single-centre study.

Objective: Neck of femur (NOF) fractures are common and serious injuries in the elderly. When a NOF fracture is suspected but is not clearly visible on radiographs, guidelines recommend magnetic resonance imaging (MRI), or computed tomography (CT) if MRI is not available/contraindicated. The aim of our study was to review the use of CT and subsequent MRI for suspected NOF fractures in patients with negative or equivocal radiographs.

MRI does not effectively diagnose ulnar-sided wrist pain in elite tennis players.

Objectives: Ulnar-sided injuries of the non-dominant wrist are common in elite tennis players using a double-handed backhand technique. This study investigated the radiological changes of the non-dominant wrist in elite symptomatic and asymptomatic players using this technique as well as healthy controls. We compared clinical findings to radiological abnormalities.

Do magnetic resonance imaging abnormalities of the non-dominant wrist correlate with ulnar-sided wrist pain in elite tennis players?

Objective: Ulnar-sided injuries of the non-dominant wrist are common in elite tennis players that use the double-handed backhand technique. This study aimed to define the relationship between ulnar-sided wrist pain in symptomatic and asymptomatic elite tennis players, and the presence of abnormalities on magnetic resonance imaging (MRI).

Materials And Methods: Fourteen symptomatic tennis players, 14 asymptomatic tennis players, and 12 healthy controls who did not play tennis, were analyzed prospectively, after undergoing MRI of their non-dominant wrist.

Comparative accuracy of magnetic resonance imaging and ultrasonography in confirming clinically diagnosed patellar tendinopathy.

Background: Diagnosis of patellar tendinopathy is based primarily on clinical examination; however, it is commonplace to image the patellar tendon for diagnosis confirmation, with the imaging modalities of choice being magnetic resonance imaging (MRI) and ultrasonography (US). The comparative accuracy of these modalities has not been established.

Hypothesis: Magnetic resonance imaging and US have good (>80%) accuracy and show substantial agreement in confirming clinically diagnosed patellar tendinopathy.

Painful diabetic mastopathy as a reason for mastectomy.

A 34 year old woman with longstanding insulin-dependent diabetes mellitus experienced disabling bilateral breast pain and tenderness associated with the benign breast lesions of diabetic mastopathy. Diabetic mastopathy is typically associated with nontender lesions, however we present a case where disabling pain and tenderness lead to bilateral mastectomy, as requested by the patient. This relieved the patient of her symptoms.

MRI findings of femoroacetabular impingement.

Objective: The purpose of our study was to evaluate MRI in the identification of labral and articular cartilage lesions in patients with a clinical suspicion of femoroacetabular impingement.

Materials And Methods: Preoperative MRI was performed in 46 consecutive patients (26 men, 20 women; age range, 21-45 years; mean age, 32.3 years) for whom femoroacetabular impingement was clinically suspected.

MRI of stress reaction of the distal humerus in elite tennis players.

Objective: The purpose of this study was to describe the MRI appearance of stress reaction in the distal humerus in 12 elite tennis players. In addition, we aimed to determine whether any MRI findings were associated with changes in recovery times.

Conclusion: Stress injury to the distal humerus is a cause of chronic arm pain among elite tennis players and may be exacerbated during full competition.

MR imaging findings of acetabular dysplasia in adults.

Objective: To evaluate the diagnostic accuracy of MR imaging in the identification of labral and articular cartilage lesions in patients with acetabular dysplasia.

Design And Patients: Pre-operative MR imaging was performed on 27 hips in 25 consecutive patients (16 males, 9 females, age range 19-52 years, mean age 31.2 years) with radiographic evidence of acetabular dysplasia (centre-edge angle of Wiberg <20 degrees).

Longitudinal study comparing sonographic and MRI assessments of acute and healing hamstring injuries.

Objective: We compared sonography and MRI for assessing hamstring injuries in professional football players (Australian football) 3 days, 2 weeks, and 6 weeks after an injury and identified imaging characteristics at baseline that may be useful in predicting the time needed for return to competition.

Materials And Methods: Sixty men who are professional football players presented with suspected acute hamstring strain underwent sonography and MRI within 3 days of injury; those who were injured returned 2 and 6 weeks later for follow-up MRI and sonography. Two radiologists interpreted either the MR images or the sonograms and were blinded to the results of the other technique.

False-positive breast screening due to fat necrosis following mammography.

Traumatic fat necrosis can result in a spectrum of imaging appearances that range from characteristically benign to those indistinguishable from malignancy. In such cases, biopsy might be required for diagnosis. The present case demonstrates a suspicious mammographic mass lesion appearing following a haematoma caused by a previous screening mammogram.

Fourteen-gauge needle core biopsy of mammographically evident radial scars: is excision necessary?

Background: Radial scars are benign lesions that may mimic breast carcinoma on mammography and usually are managed by excision biopsy. The authors report their experience with stereotactic needle core biopsy (SNCB) in sampling these lesions.

Methods: A prospective study examined a consecutive series of 75 mammographically detected radial scars from a population-based screening program.
