    Notes: Summary Cocaine drug packets were found in the gastro-intestinal tract of seven persons, charged with and arrested for presumed drug smuggling. Plain abdominal roentgenograms were positive in 4, while computer tomography of the abdomen (CT-scan) was necessary in 3 others to make the diagnosis. There were no signs of acute intoxication or bowel obstruction. All patients were treated with enemas and/or laxatives in order to evacuate the hidden packets; no complications occurred. A clinical description of the seven cases is followed by a short review of the literature, mainly focused on the possible complications of ingested drug packets and possible methods of removal.

    Notes: Abstract Two patients (a 16-month-old boy and a 53-year-old man) were referred for MR imaging of a small, subcutaneous nodule at the forearm. Plain films were available in one patient and showed a non-specific well-circumscribed lesion. Upon ultrasonography (1 patient), a nodular, well-circumscribed, hyperechoic lesion was seen. In both cases spin-echo (SE) T1-weighted images (T1W1) showed homogeneous, intermediate signal intensity (SI). On gadolinium-enhanced T1W1 (1 patient), no enhancement was observed. Both lesions showed predominant low-to-intermediate SI on T2WI. At histological examination characteristic findings of pilomatricoma were observed.

    Intestinal stenosis from mesenteric injury after blunt abdominal trauma (1999)
    Springer

    Notes: Abstract. We report a case in which blunt abdominal trauma resulted in injury to the mesentery with subsequent ischemic stricture of the adjacent small bowel. We present CT images at the time of trauma and 5 weeks later when clinical signs of intestinal obstruction occurred. We include images of enteroclysis and angiography of this uncommon sequela of blunt abdominal trauma. At surgery, a stenotic small bowel loop was found adjacent to a healed defect in the mesentery. Histological examination of the resected segment showed mucosal and submucosal ischemia with mucosal ulceration, mural inflammation, and fibrosis. Posttraumatic intestinal stenosis subsequent to a mesenteric tear should be included in the differential diagnosis in a patient with a history of blunt abdominal trauma and signs of intestinal obstruction.

    Effect of field strength on gadolinium enhancement in MR imaging (1994)

    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.

    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.

    Postmortem MRI of the brain with neuropathological correlation (1995)

    Topics: Medicine
    Notes: Abstract We prospectively correlated in vitro MRI of the brain with the neuropathological findings in patients with suspected intracranial disease. In vitro MRI was performed on 91 consecutive formalinfixed whole-brain specimens. In 60 cases, the images were correlated with the neuropathological findings (number of lesions, lesion boundaries, spread of oedema and type of lesions). As compared with neuropathology, MRI showed an equal number of lesions in 50 cases, more in 5, and less in 5 specimens, resulting in a sensitivity of 83.3%. The extent of perilesional oedema was better seen on in vitro MRI than on gross pathology. Microscopic extent of glial tumours was underestimated on both T2-weighted images and macroscopic examination. Neuropathology remains the reference study, since on in vitro MRI primary brain tumours, metastatic deposits and non-neoplastic space-occupying lesions cannot be differentiated. However, in our study MRI had a specificity of 76.6%. MRI of postmortem specimens is sensitive to focal brain lesions, and can foucus the attention of the neuropathologist to abnormal regions.

    Clinical usefulness of contrast-enhanced MP-RAGE of the brain (1996)

    Notes: Abstract Our purpose was to evaluate the usefulness of a 3D T1-weighted gradient-echo sequence (MP-RAGE) in clinical practice. We prospectively examined 200 patients with a variety of neurological disorders and symptoms. We compared lesion conspicuity and contrast enhancement on MP-RAGE images with conventional gadolinium-enhanced spin-echo (SE) T1-weighted images. Both the original MP-RAGE data and the reformatted images were characterised by improved differentiation between grey and white matter. More lesions were found on the 3D series, in both patients with neoplastic and non-neoplastic disease. Contrast enhancement of small oedematous lesions affecting the white matter in demyelinating disease was less obvious. Multiplanar reformatting, which can be realised in any desired plane and surface rendering with sophisticated segmentation algorithms superbly displayed the underlying anatomical relationships between lesions and normal brain structures. Excellent spatial resolution, the absence of posterior fossa artefacts and equivalent contrast enhancement resulted in an increased number of space-occupying lesions being found on the MP-RAGE images. Thus contrast-enhanced MP-RAGE is an alternative to conventional SE imaging in the investigation of intracranial masses. Although the total number of lesions found in patients with demyelinating disease was significantly higher on MP-RAGE, demonstration of blood-brain-barrier breakdown in active lesions was less obvious.

    MRI after successful lumbar discectomy (1996)

    Notes: Abstract Our aim was to establish the normal range of MRI findings after successful lumbar discectomy. We prospectively examined 34 consecutive patients with an excellent clinical outcome by MRI 6 weeks and 6 months after surgery. All examinations included sagittal and axial spin-echo (SE) T1-weighted images before and after intravenous gadolinium-DTPA and fast SE T2-weighted images. Contrast enhancement along the surgical tract was seen in all patients 6 weeks and 6 months after surgery. After 6 months minimal or no mass effect on the dural sac by epidural scar was seen. In 20 % of patients there was recurrent disc herniation, with mass effect. Enhancing nerve roots were seen in 20 % of patients 6 weeks postoperatively, and half of these were associated with recurrent disc herniation at the same side. None of these patients still showed nerve root enhancement 6 months after surgery. Postoperative MRI studies must be interpreted with great care since the features described in the failed back surgery syndrome are also found, to some extent, in asymptomatic postoperative patients.

    The value of MRI in the diagnosis of postoperative spondylodiscitis (2000)

    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.
