ECU tendon subluxation: A nonspecific MRI finding occurring in all wrist positions irrespective of ulnar-sided symptoms?

Background: Recurrent subluxation or dislocation of the extensor carpi ulnaris (ECU) tendon from the ulnar groove is an important cause of ulnar-sided wrist pain. Demonstration of ECU subluxation on MRI is of unclear clinical significance. Previous studies have suggested wrist positioning can affect the ECU's position relative to the ulnar groove.

Unravelling the grey zone: cardiac MRI volume to wall mass ratio to differentiate hypertrophic cardiomyopathy and the athlete's heart.

Background: Differentiating physiological left ventricular hypertrophy (LVH) in athletes from pathological hypertrophic cardiomyopathy (HCM) can be challenging. This study assesses the ability of cardiac MRI (CMR) to distinguish between physiological LVH (so-called athlete's heart) and HCM.

Methods: 45 patients with HCM (71% men and 20% athletic) and 734 healthy control participants (60% men and 75% athletic) underwent CMR.

Anabolic androgenic steroid use is associated with ventricular dysfunction on cardiac MRI in strength trained athletes.

Background: Uncertainty remains about possible cardiac adaptation to resistance training. Androgenic anabolic steroids (AAS) use plays a potential role and may have adverse cardiovascular effects.

Objective: To elucidate the effect of resistance training and of AAS-use on cardiac dimensions and function.

Sport category is an important determinant of cardiac adaptation: an MRI study.

Background: Physiological cardiac adaptation in athletes is influenced by body surface area, gender, age, training intensity and sport type. This study assesses the influence of sport category and provides a physiological reference for sport category and gender.

Methods: Three hundred and eighty-one subjects (mean age 25±5 years, range 18 to 39 years; 61% men) underwent cardiac MRI and ECG: 114 healthy non-athletes (≤3 training h/week) and 267 healthy elite athletes (mean 17±6.

Impact of revised Task Force Criteria: distinguishing the athlete's heart from ARVC/D using cardiac magnetic resonance imaging.

Background: Cardiac magnetic resonance (CMR) evaluation of athletes for arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is complicated by overlapping features such as right ventricular (RV) volume increase. The revised ARVC/D diagnostic Task Force Criteria (TFC) incorporate cut-off values for RV ejection fraction (EF) and RV end-diastolic volume (EDV) on CMR.

Design: To distinguish ARVC/D patients from athletes we compared CMR ventricular volumes, function, TFC cut-off values, and LV/RV ratios since athletes show proportionate, and ARVC/D patients disproportionate, changes in LV and RV.
