PURPOSE To retrospectively determine which features of urinary calculi are associated with their detection after virtual elimination of contrast medium at dual-energy computed tomographic (CT) urography by using a novel tin filter. MATERIALS AND METHODS The institutional ethics committee approved this retrospective study, with waiver of informed consent.(More)
During the 11-month period 1 October 1977 to 31 August 1978 a total of 44 patients with acute supination trauma of the ankle were examined. The clinical findings were compared with the results of arthrography. This revealed that direct and indirect tenderness of the anterior talofibular ligament and calcaneofibular ligament respectively, combined with a(More)
The material comprises 444 patients, aged 12-50 years, with acute sprain of the ankle, seen over an 11-month period (1.10. 1977 to 31.8. 1978). Clinical examination showed no rupture of the ligaments in 53. Arthrography in the remaining patients revealed rupture of the lateral ligaments in 209 (in two-thirds of the anterior talofibular ligament and in(More)
Diagnosis and classification of chronic obstructive pulmonary disease (COPD) may be seen as difficult. Causal reasoning can be used to relate clinical measurements with radiological representation of COPD phenotypes airways disease and emphysema. In this paper a causal probabilistic network was constructed that uses clinically available measurements to(More)
OBJECTIVE Metatarsalgia is often treated by metatarsal osteotomy. Exact knowledge of the normal anatomy of the forefoot is essential for pre-operative planning. The objective of this study was to investigate the forefoot arch during maximal loading in a randomly selected population sample. METHODS Two hundred subjects randomly selected from a municipality(More)
INTRODUCTION Patients with chronic obstructive pulmonary disease (COPD) frequently suffer from comorbidities. COPD severity may be evaluated by the Global initiative for chronic Obstructive Lung Disease (GOLD) combined risk assessment score (GOLD score). Spirometry, body plethysmography, diffusing capacity of the lung for carbon monoxide (DLCO), and(More)
Introduction: Exercise-based approaches exist; however, it is unclear whether these approaches are based on scientific findings in the literature on trunk muscle deficits in scoliosis that could be targeted by exercises. The aims of this study were to systematically review the literature to understand the functional muscular properties of paraspinal muscles(More)
In a prospective consecutive investigation radiologic tests for lateral and anterior instability in acute ankle distortion were found to be reliable indications of lateral ligament ruptures. Arthrography of the ankle joint was used as reference. Absence of instability, however, gives little information as to the ligamental status. The size of this group(More)
A method for automatically quantifying emphysema regions using High-Resolution Computed Tomography (HRCT) scans of patients with chronic obstructive pulmonary disease (COPD) that does not require manually annotated scans for training is presented. HRCT scans of controls and of COPD patients with diverse disease severity are acquired at two different(More)
As part of a clinical prospective investigations 102 patients with fresh ankle injuries underwent ankle arthrography and surgery for rupture of the lateral ligaments of the ankle. Three hypotheses concerning the improvement of the arthrographic diagnosis of rupture of the calcaneofibular ligament were tested. Two were rejected. Improvement in the diagnostic(More)
