Treffsicherheit der Magnetresonanztomographie zum Nachweis von Meniskusrissen
2000
Zur Uberprufung der diagnostischen Treffsicherheit wurden prospektiv 172 Kniegelenke mittels Magnetresonanztomographie (MRT) untersucht. Nach der MRT erfolgte bei allen Kniegelenken die arthroskopische Uberprufung der bildgebenden Diagnose. Rissbildungen des Innenmeniskus fanden sich bei 102 Patienten, am Ausenmeniskus wurde 29-mal ein Riss befundet. Unter der Annahme, dass die Arthroskopie der “golden standard” diagnostischer Masnahmen am Kniegelenk darstellt, ergab sich, dass falsch-positive MRT-Befunde am Innen- und Ausenmeniskus in jeweils 3 Fallen und falsch-negative MRT-Befunde am Innenmenikus bei 2 Kniegelenken und am Ausenmeniskus 4-mal erhoben wurden. Fur den Innenmeniskus wurde ei…
Parosteal osteosarcoma of the talus.
1995
A case of parosteal osteosarcoma in the very rare location of the talus is presented. The radiological, pathological, and clinical characteristics of parosteal osteosarcoma are described and the differential diagnosis discussed.
Die dynamische31Phosphor-Magnetresonanz-Spektroskopie des M. quadriceps: Metabolische Veränderungen unter zwei verschiedenen Belastungsformen
1997
PURPOSE The aim of the present investigation was to examine the metabolism of the quadriceps muscles of normal young individuals using dynamic 31phosphorus magnetic resonance spectroscopy. METHODS 22 normal individuals were examined in a 1.5T-MRT using a 6 cm surface coil. The metabolic changes in the quadriceps muscle as shown by the phosphorus spectrum were evaluated during rest, exercise (isometric and isotonic exercise) and during a 36-second period of recovery. RESULTS The Pi/PCr quotient rose from its resting value of 0.11 +/- 0.02 following exercise to a maximum of 0.83 +/- 0.47 (isometric) or 1.40 +/- 0.59 (isotonic) (difference p = 0.0001). Half-time recovery of Pi/PCr was 35 +/- 1…
Einsatzmöglichkeiten der MR-Arthrographie bei Erkrankungen des Schultergelenkes
1994
In a prospective study possible indications for MR arthrography of the shoulder were evaluated. 37 patients were examined before and after intraarticular administration of a 2-mmolar solution of Gd-DTPA. MR arthrography was performed if there was no joint effusion and/or an uncertain finding concerning the rotator cuff or the capsulolabral complex on plain MR images. MR arthrography leads to a better demonstration of labrum pathology in 11/22 patients and to a superior delineation of the capsuloligamentous apparatus in 20/22 cases. In 9/15 patients with impingement lesions MR arthrography allowed a differentiation of severe tendinitis from partial and small full-thickness tears of the rotat…
Eine Mannitollösung als orales Kontrastmittel in der pelvinen MRT
1995
PURPOSE Improvement of pelvic MRI using peroral administration of an aqueous mannitol solution. METHODS We retrospectively evaluated magnetic resonance examinations of 72 patients with suspected or proven pelvic abnormalities: In 36 patients, no bowel marking was carried out. In further 36 patients, we performed a contrast enhancement of the bowel by oral application of 1000 ml of an aqueous mannitol solution. RESULTS 8/36 (22%) patients suffered from diarrhoea, nausea or meteorism as a result of mannitol application. In group 2, an excellent bowel marking of the small intestine could be obtained in 36/36 (100%) patients. Contrast enhancement of the bowel significantly improved delineation …
