The purpose of this work was to evaluate the enhancement of different concentrations of gadolinium (Gd), ytterbium (Yb) and iodine in vitro and in vivo. Comparisons were made of the enhancement (HU) of Gd, Yb and iodine in concentrations ranging from 0.1 to 30 mg/ml. In vivo dynamic CT studies were performed in ten dogs with 0.5 M Gd, Yb and iodine.(More)
PURPOSE Evaluation of MRI in radiotherapy of humeroscapular periarthritis. PATIENTS AND METHODS Seventy-seven patients with humeroscapular periarthritis prospectively underwent MRI before radiotherapy. RESULTS Six months after radiotherapy, 34% of the patients had achieved complete pain relief, 35% major pain relief. Twenty percent had only slight(More)
PURPOSE The aim of this study was to evaluate whether intravenous injection of an ultrasound contrast agent aids in the visualization of focal liver lesions on power Doppler images. METHODS Fifty patients with focal liver lesions were studied by B-mode and power Doppler sonography before and after intravenous injection of the contrast agent Levovist(More)
PURPOSE The purpose of this study was to ascertain whether MR imaging, with the use of a surface coil, can accurately show small intraorbital structures; in particular, the septum orbitale. METHODS Examinations of 26 patients who underwent unilateral orbital high-resolution MR imaging for different indications were evaluated to differentiate the septum(More)
In spite of procedures such as CT angiography, MR angiography, and rotation angiography, panangiography is still indispensable in therapeutic planning for cerebral aneurysms. It is the only method that provides exact details about the size, anatomic localization, and multiplicity of aneurysms as well as relation to surrounding vessels, the presence of an(More)
The ultrasound findings of 58 patients with AIDS and ARC were analysed retrospectively. In 55% an enlarged liver, in 62% an enlarged spleen, partially with focal lesions, and in 21% enlarged abdominal lymph nodes were diagnosed. The typical focal segmental glomerulosclerosis of the kidney was observed in one case, and cholangitis in 2 patients. Abdominal(More)
In 50 patients with pulmonary disease of varying aetiology and involvement of the pulmonary interstitium, high resolution CT with 1 mm sections have been performed. Various morphological changes within the secondary lobule could be demonstrated which helped in reducing the differential diagnosis. Compared with conventional CT with 10 mm cuts it was also(More)
In 32 patients with fractures of different localisation the transverse CT layers were compared with three-dimensional reconstructions. Evaluation showed that three-dimensional CT can better visualize complicated anatomical conditions especially if there are dislocated fragments in the facial part of the skull and in the trunk of the body. Hence, 3-D CT is a(More)
