PURPOSE To determine the ability of dynamic ultrasonography (US) to depict finger pulley injuries in extreme rock climbers. MATERIALS AND METHODS Sixty-four extreme rock climbers (climbing levels 8-11 on a scale ranging from 1 to 11; Union Internationale des Associations d'Alpinisme) with finger injuries (75 symptomatic and 181 asymptomatic fingers) were(More)
OBJECTIVE The purpose of this study was to compare the diagnostic accuracy of 64-slice CT with that of invasive angiography in the detection of greater than 50% graft stenosis within 2 weeks of coronary artery bypass grafting and to investigate the clinical value of 64-slice CT. SUBJECTS AND METHODS Forty-one patients (70 grafts, 46 arterial and 24(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)
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 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 In September 1991, a mummified corpse was discovered soon after it was released by the receding ice of the Similaun glacier in the Tyrolean Alps. This body proved to be an astonishingly well-preserved man from the late Neolithic Age or early Bronze Age. To preserve the fragile mummy, scientific investigations were required to be as noninvasive and(More)
PURPOSE We describe postoperative surgical anatomy after orthotopic reconstruction of the lower urinary tract using 3-dimensional (D) computerized tomography (CT) and virtual reality endoscopy. MATERIALS AND METHODS Electronic beam CT was performed in 39 men and 15 women a mean of 60 years old with an orthotopic ileal neobladder (50) or ureteroileal(More)
The aim of this pilot study in 54 patients was to improve the visualization of the anatomy and postoperative changes in the pelvic topography after bilateral ureteroileal urethrostomy, using surface rendering of electron beam CT (EBCT) data for the 3D display. Fifty-four patients (39 men and 15 women) were scanned with an EBCT unit between 3 and 110 months(More)
PURPOSE OF REVIEW Prostate cancer is the most commonly diagnosed malignancy in men. Gray-scale ultrasound-guided systematic biopsy is the standard of care for prostate cancer detection in men with an elevated prostate-specific antigen or an abnormal digital rectal examination. Systematic biopsy may miss up to 35% of clinically relevant cancers. Color and(More)
