Immunoscintigraphy with technetium-99m labelled anti-granulocyte antibodies (AGA) is an equivalent technique to imaging with in vitro-labelled leucocytes, which is now considered state of the art in the diagnostic work-up of patients with suspected post-traumatic chronic osteomyelitis. In this study, we evaluated the use of a combined single-photon emission(More)
OBJECTIVE The purpose of our study was to assess the added value of MR mammography, mammography, and sonography compared with mammography and sonography in diagnostic evaluation of the breast. MATERIALS AND METHODS We evaluated reports of MR mammography, conventional mammography, and sonography of the breast in 89 patients who had been referred for(More)
PURPOSE To evaluate the feasibility of high-resolution magnetic resonance imaging (MRI) of trabecular bone of the wrist at 3 Tesla (3T) in vivo and to assess the potential benefit of the increased resolution for clinical assessment of structural changes in spongy bone. MATERIAL AND METHODS High-resolution MRI of the wrist was performed with a whole-body(More)
PURPOSE To evaluate the safety, efficacy, and pharmacodynamic properties of a new superparamagnetic parenteral iron oxide contrast agent for magnetic resonance (MR) imaging. MATERIALS AND METHODS Thirty-six patients with liver lesions received a bolus injection of Resovist (SH U 555 A; Schering, Berlin, Germany) at a dose of 4, 8, or 16 micromol iron per(More)
AIMS AND BACKGROUND Preoperative embolization of vertebral metastases has been shown to lower intraoperative blood loss. Nevertheless, excessive up to life-threatening blood loss can occur despite embolization. We therefore decided to evaluate possible parameters for predicting significant blood loss in a surgically homogeneous group of patients with(More)
A three-dimensional (3D) gradient-echo sequence with interleaved double-slab excitation was developed and optimized for the requirements in pediatric cardiac imaging. For this purpose high contrast between blood and myocardium signal should be obtained without the use of contrast agents. An acceptable measuring time for a large region examined with high(More)
PURPOSE To develop and to test an easily produced biological colon model with simulated polypoid lesions. Application of this phantom for the selection of an optimized scan protocol of 16-row CT colonography (CTC) for clinical use. METHODS AND MATERIAL Six polypoid lesions (1 - 6 mm) were simulated with sutures on the inner face of a porcine colon segment(More)
Hintergrund. Computertomographische Untersuchungen erlauben eine v. a. im Kopf- und Halsbereich bedeutsame überlagerungsfreie Darstellung anatomischer Strukturen. In der Regel genügt eine präoperative Untersuchung zur Beurteilung des Ausgangszustands, bei bestimmten Indikationen ist jedoch eine intraoperative Kontrolle des Behandlungserfolgs wünschenswert.(More)
