    MR imaging of eosinophilic granuloma: report of 11 cases (1993)
    Springer
    Skeletal radiology 22 (1993), S. 163-166 
    Details
    ISSN: 1432-2161
    Keywords: Eosinophilic granuloma ; Magnetic resonance imaging (MRI)

    Topics: Medicine
    Notes: Abstract The findings in 11 patients with histologically proven eosinophilic granuloma (EG) examined by magnetic resonance imaging (MRI) are described. In contrast with the variable appearance of EG on conventional radiography and computed tomography (CT), relatively constant features — intermediate to high signal intensity on T1-weighting, high signal intensity on T2-weighting, marked enhancement — were found on MRI. MRI was superior to other imaging methods in demonstrating bone marrow involvement and any accompanying soft tissue mass or inflammation. Intermediate to high signal intensity on Tl-weighting and marked contrast enhancement could not be “explained” by histological findings. Prediction of the evolutionary phase of EG by MRI remains questionable because of the phase I (proliferative) histology of all 11 lesions.

    Angiographic diagnosis and intervention in iatrogenic gastrointestinal hemorrhage: report of five cases (1992)
    Springer
    European radiology 2 (1992), S. 66-69 
    Details
    ISSN: 1432-1084
    Keywords: Angiography ; Iatrogenic gastrointestinal hemorrhage ; Embolization
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract We present five patients with iatrogenic gastrointestinal hemorrhage. In all cases angiography was successful in localizing the site of bleeding. In four cases transcatheter etnbolization therapy with Gelfoarn particles or Gianturco coils was carried out. This was completely successful in three patients and partially successful in the fourth. Complications occurred in two patients.

    Effect of field strength on gadolinium enhancement in MR imaging (1994)
    Springer
    European radiology 4 (1994), S. 557-560 
    Details
    ISSN: 1432-1084
    Keywords: MR ; Contrast media ; Gadolinium ; Contrast enhancement ; Field strength

    Topics: Medicine
    Notes: Abstract This studv was designed to evaluate the influence of magnetic field strength on the relative enhancement effect (RE) of gadolinium (Gd)-chelates. Dilution series of two paramagnetic contrast agents (Gd-DTPA and Gd-DOTA) were examined in three commercially available MR systems. operating at different field strengths (02 T, 1. T, and 1.5 T). The RE was plotted against Gd concentration. The highest increases in signal intensity occurred with Gd concentrations of approximately L.0 mmol/L. No significant difference in RE was observed between MR systems ranging in field strength from 0.? T to 1.5 T. The RE of Gd-DTPA and Gd-DOTA was found to he equivalent.

    The value of MRI in the diagnosis of postoperative spondylodiscitis (2000)
    Springer
    Neuroradiology 42 (2000), S. 580-585 
    Details
    ISSN: 1432-1920
    Keywords: Key words Spine ; surgery ; Infection ; Magnetic resonance imaging

    Topics: Medicine
    Notes: Abstract We evaluated the role of MRI in the diagnosis of postoperative spondylodiscitis. Spondylodiscitis is a serious complication of surgery, and the diagnosis frequently depends on a combination of clinical, laboratory and imaging findings. We compared the MRI findings in six patients with biopsy- or surgery-proven spondylodiscitis with those in 38 asymptomatic postoperative patients. Contrast enhancement and signal changes in the intervertebral disc or the vertebral endplates are not specific for spondylodiscitis, being also seen in the asymptomatic patients. However, absence of Modic type 1 changes, of contrast enhancement of the disc or of enhancing paravertebral soft tissues suggests that the patient does not have spondylodiscitis. MRI appears more useful for exclusion than for confirmation of postoperative spondylodiscitis.
