Abstract		Background. The purpose of this study was to estimate the value of native magnetic resonance imaging (MRI) and direct gadopentate (Gd-DTPA) magnetic resonance arthrography (MRA) in diagnosing posttraumatic pathological changes of the glenohumeral joint. Patients and methods. In 27 consecutive patients with clinicaly significant trauma in whom native MRI of the glenohumeral joint was not diagnostically conclusive direct MRA with paramegnetic contrast agent was accomplished. Following intraarticular injection of Gd-DTPA diluted in saline (concentration 0.2 mmol/l) T1W spin echo (SE) and gradient echo (GE) images were performed. Diagnostic results of native MRI and MRA were compared. Results. MRA revealed 5 rotator cuff lesions, 7 labral lesions, 4 osteochondral injuries and a loose body which were not definitely proved by native MRI. All the pathological findings of MRA were confirmed operatively or arthroscopically. Conslusion. Direct MRA with Gd-DTPA showed to be a more sensitive technique for the demonstration of clinically significant intraarticular posttraumatic changes than noncontrast MRI.
Summary		Izhodišča. Namen študije je bil ugotoviti vrednost nativnega slikanja z magnetno resonanco (MRI) in direktne magnetnoresonančne artrografije (MRA) s paramagnetnim kontrastnim sredstvom (Gd-DTPA) pri diagnostični opredelitvi posttravmatskih sprememb ramenskega sklepa. Bolniki in metode. Direktna magnetnoresonančna artrografija je bila narejena na 27 bolnikih s težjo poškodbo ramenskega sklepa, pri katerih MRI ni omogočila zanesljive diagnoze. Po intraartikularni aplikaciji Gd-DTPA v fiziološki raztopini (koncentracija 0.2 mmol/l) je bilo narejeno slikanje s spin echo in gradient eho tehniko. Primerjali smo rezultate obeh preiskav. Rezultati. MRA je pokazala strgano rotatorno manšeto pri 5 bolnikih, lezije labruma v 7 primerih, 4 osteohondralne poškodbe in prosto telo v sklepu, posttravmatske spremembe, ki jih MRI ni odkrila. Vsi rezultati MRA so bili potrjeni artroskopsko ali z operativnim posegom. Zaključki. V naši študiji se je MRA v primerjavi z MRI pokazala kot občutljivejša tehnika za prikaz klinično pomembnih posttravmatskih intraartikularnih sprememb ramenskega sklepa.
