    Notes: Abstract We report herein a case of an iatrogenic superior pancreaticoduodenal arterial aneurysm which ruptured into the duodenal stump of a Billroth II partial gastrectomy. Superselective angiography was used for the diagnosis, and successful embolization performed nonoperatively. A review of the literature revealed both the etiology and site of rupture in this case to be extremely uncommon.

    Topics: Medicine
    Notes: Abstract In order to test MRI ability to detect the number and the sites of coronary artery by-pass grafts (CABGs), 22 patients with CABGs were studied. The detection of a neo-vessel in even one of the examination slices was considered as positive for the study, disregarding the difference between its origin and course. With such a criterion, MRI total percentage of vascular bridges identification resulted in 76.1% (51/67) with very low values for CABGs implanted on diagonal, obtuse marginal and posterior descending vessels (11/24=45.8%). These results lead to the conclusion that, although MRI has some advantages in the identification of CABGs implanted on the main coronary vessels in the early post-operative period, its extensive use cannot be proposed at the present state of the art.

    Notes: Abstract The authors have used MRI for investigation of 41 patients with pancreatic tumours. MR examinations were performed with 0.5 T superconductive equipment. Short TR, short TE spin echo (SE) sequences were obtained with 8 averages and 256×256 matrix. T2-weighted sequences were also acquired. T1-weighted SE sequences provided more detail, with high intrinsic contrast between the tumour and the normal pancreas; small lesions (19 smaller than 3 cm in diameter) were always detected on these images. T2-weighted SE sequences were not useful for lesion detection, due to the lower intrinsic contrast and the number of artefacts. T2-weighted sequences proved helpful for lesion characterisation in two cases of cystoadenocarcinoma only. Staging of the tumour was possible with MRI, with good assessment of local spread, lymphoadenopathy, vascular involvement and hepatic metastases. MRI of the pancreas at medium field strength can be an alternative to CT in selected cases.

    Keywords: Liver, MRI studies ; Pancreas, MRI studies ; MR contrast agents
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract The authors describe the results obtained with dynamic MRI of the parenchymal organs during the infusion of contrast agents. Thirteen patients with hepatic and pancreatic lesions were studied. RASE sequences were characterized by TR of 260 ms, TE of 16 ms, NEX 1, matrix 128 × 256. Infusion of the contrast agent started 15 s prior to the beginning of the pulse sequence and continued throughout the pulse sequence (25 s). In this way, a continuous inflow of contrast agent in abdominal organs was expected during the acquisition time. The conventional dose of Gd-DTPA was employed (0.1 mmol/kg). The results demonstrate a highly relevant pancreatic enhancement in the early arterial phase of perfusion, with values of SE/N of 18.1 versus 8.5 in the subsequent sequence. However, in the liver the perfusion study did not improve the parenchymal enhancement, with values of 9.3 versus 15.3 in the late phase. There was no improvement of hypontense lesion detections in the liver, while the hypervascular lesions were visualized with a high signal intensity in the early perfusion study, disappearing in the later sequences.
