CONTEXT Deciding on the appropriate therapy for patients with malignant diseases mandates accurate tumor staging with whole-body coverage. Magnetic resonance imaging (MRI) and a combined modality including positron emission tomography (PET) and computed tomography (CT) provide whole-body tumor staging in a single session. OBJECTIVE To determine the(More)
INTRODUCTION The purpose of this study was to assess the diagnostic accuracy of magnetic resonance colonography (MRC) for its ability to detect and quantify inflammatory bowel disease (IBD) affecting the colon. Endoscopically obtained histopathology specimens were used as the standard of reference. MATERIALS AND METHODS Fifteen normal subjects and 23(More)
The aim of this study was to compare the results of whole-body MRI using a recently developed rolling table platform with findings of nuclear scintigraphy in patients with bone metastases. Twenty-six patients with known or suspected bone metastases who had undergone radionuclide scintigraphy were examined by MRI. Patients were placed on a rolling table(More)
PURPOSE To compare the results of whole-body magnetic resonance (MR) imaging with staging based on computed tomographic (CT), dedicated MR imaging, and nuclear scintigraphic results as standard of reference. MATERIALS AND METHODS Fifty-one patients with known malignant tumors were included in the study. Patients were placed on a rolling table platform(More)
PURPOSE To assess a strategy for fecal tagging with barium sulfate as an inexpensive tagging agent in conjunction with magnetic resonance (MR) colonography in patients suspected of having colorectal lesions. MATERIALS AND METHODS Twenty-four patients suspected of having colonic lesions because of rectal bleeding, positive fecal occult blood test results,(More)
An ultrafast three-dimensional (3D) sequence was developed, enabling the acquisition of 44 contiguous 2.0- to 2.2-mm thin sections, during intravenous application of paramagnetic contrast, in a single breath-hold. To estimate the potential clinical usefulness, images were assessed qualitatively and quantitatively with regard to visibility of main, lobar,(More)
PURPOSE The aim of this study was to assess a new strategy of MR colonography for the detection of colonic polyps/malignancy. The technique is based on a rectal enema with water in combination with the intravenous application of a paramagnetic contrast agent. METHODS Twelve subjects were included in this study either due to suspected colorectal tumors or(More)
Kardiovaskuläre Erkrankungen und ihre Folgen stellen in den westlichen Ländern ein bedeutendes Gesundheitsproblem mit steigender Prävalenz dar. Der Früherkennung und Vorsorge dieser Erkrankungen kommt deshalb in der Zukunft eine wachsende Bedeutung zu. Mit der Magnetresonanztomographie (MRT) gelingt heute eine umfassende Analyse des kardiovaskulären(More)
The authors qualitatively and quantitatively assessed a solution containing 0.2% locust bean gum (LBG) and 2.5% mannitol (mannitol-LBG) dissolved in water to provide a negative oral contrast material in dual-modality positron emission tomography (PET)/computed tomography (CT) scanning. PET/CT was performed in 60 patients with cancer after oral(More)
OBJECTIVE The purpose of this study was to determine the added diagnostic value of various three-dimensional (3D) data viewing techniques when analyzing contrast-enhanced 3D MR angiography. MATERIALS AND METHODS Twenty patients (mean age, 62 years) with symptomatic peripheral vascular disease were assessed with breath-hold, contrast-enhanced 3D MR(More)
