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)
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)
O1 The functional properties of paraspinal muscles in adolescents with idiopathic scoliosis (AIS): A systematic review of the literature 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.(More)
INTRODUCTION Computed tomography colonography (CTC) is the primary radiological examination for detection of colorectal cancer and premalignant polyps. It is a complex technique that requires special training and experience of both the radiographers performing the colonography and the radiologists who interpret the results. The considerable number of CTC(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)
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)
