BACKGROUND The most typical symptoms of patients with nasal septal perforation (SP) are crusting and recurrent nosebleed. The objective of the study was to determine the influence of SP on intranasal temperature profile and airflow patterns during inspiration by means of numerical simulation. METHODS Two realistic bilateral models of the human nose with(More)
Im vorliegenden Beitrag wird eine Pilotstudie zur Überprüfung der Machbarkeit und des klinischen Nutzens einer hochauflösenden virtuellen Echtzeitlaryngoskopie aus Spiral-CT-Datensätzen vorgestellt. 12 Patienten mit Erkrankungen im Kehlkopfbereich (3 Stimmlippentumore, 2 Larynxkarzinome, ein in den Larynx eingebrochenes Schilddrüsenkarzinom und 6(More)
The aim of this study was evaluation of MRI alone and in combination with mammography and galactography in the diagnosis of intraductal papillomas. From 1994 to 1998, a total of 48 women presenting with pathologic mammary secretion underwent galactography and magnetic resonance mammography (MRM). Thirty-five patients aged 16–71 years (average age 46 years)(More)
The aim of this study was to evaluate and describe MRI epidurography as a new imaging tool. Five volunteers and one patient were investigated with MR epidurography after injection of 20 ml Gd-DPTA solution (1 : 250/1 ml Gd-DPTA/250 ml normal saline). Magnetic resonance epidurography is possible. With fat-suppression techniques, the contrast between Gd-DPTA(More)
Retrospective evaluation of interventional embolization therapy in the treatment of gastrointestinal hemorrhage over a long-term observation period from 1989 to 1997. Included in the study were 35 patients (age range 18–89 years) with gastrointestinal bleeding (GI) referred for radiological intervention either primarily or following unsuccessful endoscopy(More)
The aim of the study was to evaluate the additional findings of MRI following small bowel enteroclysis and to compare the efficacy of negative and positive intraluminal contrast agents. Fifty patients with inflammatory or tumorous small bowel disease were investigated by small bowel enteroclysis and consecutive MRI using breathhold protocol (T1-weighted(More)
Multi-detector row computed tomography (MDCT) enables fast and thin acquisition of the abdominal anatomy. This allows multi-pass multi-planar studies that can be obtained during defined circulatory phases. When bolus timing is adequate, arterial phases with high contrast levels provide "free lunch" CT angiographies eliminating the need for diagnostic(More)
After multiple revisions of her right hip arthroplasty, an 83-year-old woman developed deep infection with a chronic draining sinus. In August 2002 severe acute bleeding occurred through this fistula. Angiography revealed a pseudoaneurysm of the right external iliac artery. Because of the multiple pathologies affecting this ASA grade IV patient,(More)
Die proximale Humerusfraktur ist eine typische Verletzung des älteren Menschen mit osteoporotischer Knochenqualität. Dies erschwert die operative Stabilisierung, da es in der schlechten Knochenstruktur häufig zu sekundären Dislokationen kommt. Winkelstabile Implantate haben eine erhöhte Stabilität zum Ziel durch Anwendung des Fixateur-interne-Prinzips. Die(More)
