OBJECTIVE The objective of our study was to prospectively compare the diagnostic performance of MR arthrography and conventional MRI with surgical correlation in the same patient for detecting labrum and articular cartilage defects. SUBJECTS AND METHODS Twenty-eight patients (mean age, 31.8 years) underwent MR arthrography, conventional MRI, and(More)
OBJECTIVE The purpose of this article is to identify the most rotation-stable hindfoot alignment measurement techniques on hindfoot alignment view and long axial view radiographs. MATERIALS AND METHODS Hindfoot alignment was quantified on hindfoot alignment view and long axial view radiographs of a phantom in different rotation positions. Rotation(More)
OBJECTIVE The purpose of this study was to evaluate the frequency of oedema and fatty degeneration of the soleus and gastrocnemius muscles in patients with Achilles tendon abnormalities. METHODS Forty-five consecutive patients (mean 51 years; range 14-84 years) with achillodynia were examined with magnetic resonance (MR) images of the calf. The frequency(More)
OBJECTIVES To investigate the accuracy of biplane radiography in the detection of fractures of the thoracic spine in patients with minor trauma using multidetector computed tomography (MDCT) as the reference and to compare the dose of both techniques. METHODS 107 consecutive trauma patients with suspected fractures of the thoracic spine on physical(More)
PURPOSE To gain insight into the professional characteristics of radiologists in Switzerland and to determine how to enhance the attractiveness of radiology to medical graduates as a specialty. MATERIALS AND METHODS Data from 262 members of the Swiss Society of Radiology (m:f = 76:24%) obtained in a questionnaire survey were analysed regarding(More)
The arousal or novelty response (increased frequency of electric organ discharge in the presence of an electric stimulus delivered by a pair of electrodes placed in the water of the experimental chamber) and its habituation were studied in Gymnotus carapo, a weak field electric fish, in different seasons (September and March) and in animals with extensive(More)
OBJECTIVE Focal myositis of the iliopsoas muscle is a rare condition. A case is presented, emphasizing the value of ultrasound for detection, localisation, image-guided biopsy and follow-up in correlation with CT and MRI findings. MATERIAL AND METHODS A 58-year-old woman was referred to our clinic with strong left sided inguinal pain, which radiated to(More)
OBJECTIVE To investigate the ability of coronal non-weight-bearing MR images to discriminate between normal and abnormal hindfoot alignment. METHODS Three different measurement techniques (calcaneal axis, medial/lateral calcaneal contour) based on weight-bearing hindfoot alignment radiographs were applied in 49 patients (mean, 48 years; range 21-76(More)
Imaging of the hip abductors plays an increasing role for the evaluation of greater trochanteric pain in patients with and without total hip arthroplasty. This review article addresses the anatomy of the hip abductors and their intervening bursae. It highlights different possible imaging appearances such as tendinopathy or partial and full thickness tears(More)
We report the observation of a child born at 38 5/7 weeks' gestation, who presented with marked microcephaly and suffered from persistent intractable epilepsy up to his death at the age of 5 days. Magnetic resonance imaging suggested lissencephaly. But interestingly no submicroscopical deletion in LIS-1 gene could be detected and true lissencephaly could(More)
