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)
By increasing the strength of the magnetic field gradients of a whole-body imager to 9.4mT/m, it was possible to obtain spin-echo images with short echo delays and high spatial resolution. The reduction of the pixel size was effected either by decreasing the field of view or by increasing the scan matrix (512(2) pixel). To prevent loss of signal-to-noise(More)
This is the first report to be published on olfactory evoked potentials in patients with well-defined lesions of the central nervous system and the trigeminal nerve. Absence of olfactory evoked potentials is seen in post-central and parietotemporal lesions. The first peak of the so-called olfactory evoked twin potential is absent in lesions of the basal(More)
A new fracture type visible on CT images of the base of the skull is described. In this fracture the sphenoidal connection to the zygomatic and temporal bone breaks off all its three extensions. It was recognized in five patients with severe head injuries. In three surviving patients it was associated with ipsilateral persistent amaurosis. This fracture(More)
