Comparison of magnetic resonance tomography with computerized axiography in diagnosis of temporomandibular joint disorders.

This study compared the accuracy of two noninvasive methods, computerized axiography and magnetic resonance tomography (MRT), in diagnosing temporomandibular joint (TMJ) disorders. Forty-seven subjects underwent axiography and subsequent assessment of the TMJ by MRT. The statistical analysis referred to the correlations of the most relevant clinical diagnoses, i.

Wide scapholunate joint space in lunotriquetral coalition: a normal variant?

The radiologic appearances of 70 lunotriquetral coalitions in 52 patients were evaluated to determine whether a wide scapholunate joint space in subjects with this congenital abnormality reflects a scapholunate ligament disruption or is a normal variant. When the middle of the scapholunate joint space was larger than the capitolunate or third carpometacarpal joint space widths, it was considered to be abnormally wide. In 32 of 70 wrists (46%), a wide scapholunate joint space was detected.

[The percutaneous aspiration and drainage of infected fluid retention after organ transplantation].

Local postoperative infections in immunosuppressed patients carry a high mortality rate. In this group of patients interventional radiological procedures are particularly valuable in diagnosis and treatment. We report on the results of radiologically controlled aspirations (11 cases) and drainage (37 cases) of infected fluid collections in 47 patients following transplantation of various organs.

[MRI of the temporomandibular joint. Demonstrability and significance of the retro-articular vascular plexus].

The retro-articular vascular plexus of the temporomandibular joint (TMJ) is of great importance for the function of this joint. Aim of this study was to determine the amount of increase of signal intensity in the retro-articular vascular plexus after intravenous injection of contrast medium and to figure out potential advantages of this procedure. The posterior band of the articular disc--a landmark in the diagnosis of disc dislocations--becomes prominent after injection of contrast medium.

MRI of cartilaginous tumours of the larynx.

Cartilaginous lesions of the larynx are uncommon, approximately 250 cases being documented in the literature. In general, these tumours grow slowly, exhibiting only local aggressiveness. Distant metastases are rare.
