Thirty-two macerated femora were examined by CT in order to determine the degree of anteversion and to relate this to the position of the femur and to the various reference lines quoted in the literature. The accuracy of CT is the same as that of the Rippstein method, provided the following conditions are met: 1. Position of the femur with its long axis(More)
A CT procedure for objective measurements of tibial torsion independent of axial rotation in the nearby joints is described. Transverse sections in defined planes of the tibia permit easy calculation of normal and abnormal congenital or posttraumatic angles of torsion. In 69 limbs normal tibial torsion was 40 degrees +/- 9 degrees. In a series of 42 limbs(More)
Owing to the rapid development of scanner technology, thoracic computed tomography (CT) offers new possibilities but also faces enormous challenges with respect to the quality of computer-assisted diagnosis and therapy planning. In the framework of the Virtual Institute for Computer Assistance in Clinical Radiology cooperative research project, a(More)
We report on two spontaneous cases of microangiopathic hemolytic anemia (MAHA) as first manifestation due to metastasized signet ring carcinoma, one of gastric and one of unknown origin. The patients presented with an acute onset of Coombs negative hemolytic anemia and fragmentocytes in the peripheral blood smear which are typical for MAHA. These case(More)
The temporomandibular joints (TMJs) of 60 patients with arthrographically confirmed internal derangements and 30 volunteers were examined with single photon emission computed tomography (SPECT). Semiquantitative evaluation was done by forming a quotient from the counts of a constantly sized TMJ-ROI relative to the overall counts of the cranium. The(More)
The computed tomographic morphology of malignant choroidal melanoma and its perfusion characteristics are described. Thirty-three static and serial CT examinations made on 29 patients with choroidal melanoma, three with pseudotumors of the macula and one with choroidal metastasis revealed the choroidal melanoma to be usually a hyperdense, markedly perfused(More)
Evaluation of tibiofibular motion in vivo has been possible only by invasive methods. A new noninvasive method has been developed that uses computed tomography (CT). A special device was constructed for use on the CT table to study fibular motion with load placed across the ankle. From dorsal to plantar flexion the fibula moved 1.1 +/- 0.4 mm medially with(More)
33 CT-investigations of 23 patients with malignancies of the shoulder girdle were analyzed. In 80% of the surgically treated bone tumours of 17 patients the presence and extend of soft tissue infiltration and of osseous destruction could be delineated. The size of the 6 soft tissue tumours was better demonstrated by CT than by any other radiologic(More)
