Eighteen patients with mediastinal involvement of Hodgkin disease were examined with magnetic resonance (MR) imaging before and during therapy to find out if size of residual masses could be predicted from the MR characteristics of the tumor at diagnosis. After the first treatment, a significant decrease in T2 values and signal intensity ratios of tumor to(More)
PURPOSE To evaluate the collective incidence of, and experience with, aortoenteric fistula after endovascular aortoiliac therapy. MATERIALS AND METHODS A systematic literature research was performed to identify cases of aortoenteric fistulation after aortic stent-graft procedures or stent implantation. RESULTS The review revealed 16 cases of(More)
An attempt was made to explore whether relaxation times and/or normalized image intensities obtained from magnetic resonance imaging (MRI) can separate malignant and non-malignant lymphomatous tissue. Spin-echo (SE) techniques with repetition times of 500 and 1,500 ms and echo times of 35 and 70 ms were used for estimating T1 and T2. Estimation of T1 and T2(More)
BACKGROUND Transcatheter arterial embolization (TAE) is considered a safe, life-saving procedure in postpartum hemorrhage (PPH), but its long-term effect on menstruation and fertility is unclear. PURPOSE To investigate technical aspects and the evaluation of complications, focused on menstrual cycle and fertility, using TAE in patients with PPH. (More)
The bone marrow of the spine, pelvis and proximal femora was examined with MR imaging at diagnosis in 30 cases of multiple myeloma (MM), and during treatment on 69 occasions. The MR pattern was normal, focal or diffuse and correlated to stage. A tumour mass index (TMI) was calculated by estimating the total myeloma mass visualised at MR imaging. The TMI(More)
PURPOSE To describe the radiologic findings in patients with spinal tuberculosis (TB). MATERIAL AND METHODS Out of a total of 503 patients with TB, 63 (13%) had involvement of the spine. RESULTS In 40 patients, the spine was the only location; 20 patients had concomitant chest TB. Conventional radiographs gave a good overview, CT visualized the(More)
PURPOSE To prospectively compare the diagnostic accuracy of duplex ultrasonography, captopril renography, computed tomography angiography (CTA), and 3D Gd magnetic resonance angiography (MRA) in diagnosing hemodynamically significant renal artery stenosis (RAS). MATERIAL AND METHODS The standard of reference was measurement of transstenotic pressure(More)
Twenty-four patients with malignant bone marrow involvement or polycythemia vera, 8 patients with reactive bone marrow and 7 healthy individuals were examined with spin-echo magnetic resonance imaging at 0.35 T and 0.5 T. Signs of an increased longitudinal relaxation time, T1, were found when normal bone marrow was replaced by malignant cells, polycythemia(More)
Fifty patients with non-Hodgkin lymphoma (NHL) were examined with magnetic resonance (MR) imaging in order to analyze whether it is possible to distinguish in vivo between the two major prognostic groups, low-grade NHL and high-grade NHL. Most high-grade NHL nodes (15 of 24 [63%]) had an inhomogeneous appearance at MR imaging, in contrast to low-grade NHL(More)
PURPOSE To retrospectively compare the outcome of transcatheter arterial embolization (TAE) and surgery as salvage therapy of upper gastrointestinal bleeding after failed endoscopic treatment. MATERIALS AND METHODS From January 1998 to December 2005, 658 patients were referred to diagnostic/therapeutic emergency endoscopy and diagnosed with upper(More)
