Computer generated three-dimensional stereolithographic models of middle Pleistocene skulls from Petralona and Broken Hill are described and compared. The anterior cranial fossae of these models are also compared with that of another middle Pleistocene skull, Arago 21. Stereolithographic modelling reproduces not only the outer surfaces of skulls, but also(More)
The 600,000-year-old cranium from Bodo, Ethiopia, is the oldest and most complete early Middle Pleistocene hominid skull from Africa. "Virtual endocast" models created by three-dimensional computed tomography (CT) techniques indicate an endocranial capacity of about 1,250 cc for this cranium (with a reasonable range between approximately 1,200-1,325 cc,(More)
The corpse of a Late Neolithic individual found in a glacier in Oetztal is unusual because of the intact nature of all body parts that resulted from the characteristics of its mummification process and its protected geographical position with regard to glacier flow. Anthropological data indicate that the man was 25 to 40 years old, was between 156 and 160(More)
Since the discovery of the Tyrolean Iceman in 1991 advanced imaging and post processing techniques were successfully applied in anthropology. Specific techniques include spiral computed tomography and 3-dimensional reconstructions including stereolithographic and fused deposition modeling of volume data sets. The Iceman's skull was the first to be(More)
PURPOSE To investigate the feasibility of imaging crossing vessels at the ureteropelvic junction (UPJ) preoperatively by means of contrast agent-enhanced color Doppler imaging (CDI). MATERIALS AND METHODS Twenty-nine patients (13 female patients, 16 male patients; age range, 17-76 years; mean age, 45 years) with symptomatic UPJ obstruction were examined(More)
OBJECTIVE The aim of this study was to identify recognizable landmarks on coronal CT (CCT) scans for the localization of the anterior and posterior ethmoid arteries, which are important anatomic structures and surgical landmarks within the ethmoid sinuses. MATERIALS AND METHODS Four series of plastinated cadaver specimens and 80 CCT examinations were(More)
A 65 year old man was found to have mucormycosis cerebri during immunosuppression after treatment of hairy cell leukaemia with 2-chlorodeoxyadenosine. Although mucormycosis cerebri has a poor prognosis, the patient survived after systemic administration of high dose amphotericin B, extensive excision of the abscess, and additional local application of(More)
A short introduction to the technical aspects of magnetic resonance imaging (MRI) - knowledge of which is indispensable for the appropriate obtaining and interpretation of MRI images of the spine - is followed by an overview of detectable physiological bone marrow changes as seen on MRI over the course of life. The ability of MRI to depict degenerative and(More)
The wall of the vertebral canal is formed differently at various levels of the spinal column. These differences depend both on the formation of the elements of the neural arch (pedicle and lamina), and on the arrangement of the joints of the articular processes. The outline of the vertebral canal is determined by the ligaments between the vertebrae, one of(More)
