PURPOSE To test the feasibility of k-space segmented gradient-echo pulse sequences for free-breathing coronary magnetic resonance angiography (cMRA) on a clinical 3T system. MATERIALS AND METHODS T2-prepared, fat-suppressed turbo field echo (TFE, turboFLASH, SFPGR) as well as balanced TFE (b-TFE, trueFISP, FIESTA, segmented SSFP) sequences with navigator(More)
PURPOSE Evaluation of digitized chest x-ray for the detection of pulmonary infiltrations in bone marrow transplant patients during aplasia. METHODS Digitized chest x-rays of 40 patients (21 female, 19 male) with "Fever of unknown origin" (FUO) were evaluated concerning radiological signs of pulmonary infiltrations and correlated to clinical findings,(More)
Tardive dyskinesia (TD) is a debilitating side effect of long-term treatment with neuroleptics with an unclear pathophysiologic basis. It has been proposed that TD may be a result of neuroleptic-induced oxidative stress. To investigate this hypothesis, we studied if neuroleptic-induced oral dyskinesias in rats, a putative analogue to human TD, could be(More)
Neurological complications are a relevant cause of morbidity and mortality after haematopoietic stem cell transplantation (SCT). We retrospectively analysed neurological complications of 165 paediatric patients who underwent SCT between 1996 and 2003. In all, 111 (67%) transplantations were allogeneic and 54 (33%) transplantations were autologous. Post-SCT(More)
PURPOSE The purpose of this study was to compare refractions measured with three different autorefractors. METHODS The refractive error of each eye of 50 adults aged 17 to 59 years (mean, 30.5 years) was measured without cycloplegia using the Canon R-1 and two newer instruments, the Grand Seiko WR-5100K and the Nidek ARK 700-A. For the first two, an(More)
Twenty autologous bone marrow (BM) and 25 peripheral blood stem cell (PBSC) grafts were collected from a total of 40 consecutive patients with BCR-ABL+ acute lymphoblastic leukemia (ALL) in first (n = 37) or second (n = 3) complete morphological remission and subsequently purged with a cocktail of anti-CD19, -CD10, AB4 MoAbs and immunomagnetic beads (IMB).(More)
PURPOSE To compare the radiation dose of whole-body multislice CT (MSCT) and conventional radiography with organ-specific CT in polytrauma. MATERIALS AND METHODS The whole-body MSCT encompassing brain, neck and midface, chest, abdomen and pelvis was performed on a Somatom Volume Zoom (Siemens). Conventional radiography consisted of chest and cervical,(More)
UNLABELLED Since aspects of demographic transition have become an essential part of socioeconomic, medical and health-care research in the last decades, it is vital for the radiologist to discriminate between normal ageing related effects and abnormal imaging findings in the elderly. This article reviews functional and structural aspects of the ageing lung(More)
Reduction of homologous blood requirement in cardiac surgery is of increasing interest and may be achieved by various technical and pharmacological means. High-dose aprotinin (about 840 mg, equivalent to 6 million Kallikrein inactivator units), a serine proteinase inhibitor, was administered during open heart surgery to 60 patients refusing homologous blood(More)
PURPOSE To evaluate the image quality of thin-section MSCT examinations of low-contrast objects such as liver lesions, and to find out whether a thin slice technique requires an increase in radiation dose. MATERIALS AND METHODS MSCT examinations of the liver were performed in the portal venous phase on a Volume Zoom Scanner (Siemens, Erlangen) with a(More)
