[Diagnosis of odontogenic maxillary sinusitis by spiral computed tomography using a dental program].

Genyantrum mucosal changes and the upper jaw ridge were analyzed in different forms of periodontitis and in cases of endodontic treatment failure with the dental filling material being in maxillary sinus cavity. Spiral computed tomography using the Denta Scan software could confirm the odontogenic nature of the changes found in 57 (85.0%) patients with suspected maxillary sinusitis.

[Magnetic resonance imaging of the ankle joint and foot: possible diagnostic errors].

The paper deals with the visualizing study of the ankle joint and foot by MRI and with the problems in the interpretation of magnetic resonance images in health. For this, 50 healthy volunteers without diseases and lesions of the ankle joint and foot were examined. The study was performed by using flexible superficial coils and T1-, T2-, and proton-weighed pulse-sequences in the orthogonal projections.
