| 1 | Echoplanar diffusion - weighted MRI with intravenous gadolinium - DTPA显示文摘It is occasionally necessary to repeat diffusion weighted imaging(DWI)after giving intravenous contrast medium(CM).However,the effects of CM on DWI and apparent diffusion coefficients(ADC)have not been fully ex-amined.The aim of this prospective study was to investigate whether there are any diagnostically significant dif-ferences between echo-planar imaging(EPI)-DWI before and after intravenous CM.EPI-DWI was acquiredtwice in 203 consecutive patients before and after i.v.CM.Three blinded readers rated the diagnostic | Fitzek C Mentzel HJ Fitzek S Sauner D Kaiser WA Reichenbach JR | 2003 | 中国神经肿瘤杂志2003，1，4： | 15 |
| 2 | Magnetic resonance imaging in children and adolescents with chronic inflammatory bowel disease显示文摘Inflammatory bowel diseases(IBD) represent challenges, both from a diagnostic, and therapeutic point of view. Deep-seated anatomic structures are difficult to assess by ultrasound technique alone. As radiation-free alternative cross-sectional imaging method, magnetic resonance imaging of the intestinal structures is costly and time-consuming. Examination of pediatric patients imply additional considerations: reduction of body motions in younger children and consideration of the most appropriate preparation, and examination technique. The demanding Sellink technique is the only means for appropriately distending the lesser intestine in order to detect small bowel strictures. Oral intake of contrast medium(CM) alone shows its limitations regarding distensibility. The need for intravenous contrast media application needs to be considered, too. Active inflammation of both intestinal wall, and mesentery can be demonstrated accurately. Nevertheless, viable alternatives to CM application is desirable, considering non-negligible adverse reactions. Recent data suggest diffusion weighted imaging might fill this diagnostic gap. Irrespective of sequence technique chosen, bowel movement remains a major obstacle. Antispasmolytics in their function as smooth muscle relaxants help in improving image quality, however, their use in children might be off-label. Optimal preparation for the examination and appropriate imaging technique allow for diagnosing typical patterns of changes in IBD, such as bowel wall thickening, ulcers, mural stratification, strictures, creeping fat, and comb sign, and lymphadenopathy. The article gives a detailed overview of current significance of magnetic resonance imaging pediatric patients suffering from IBD, considering indications, limitations, and safety aspects. | Hans-Joachim Mentzel Steffen Reinsch Monika Kurzai Martin Stenzel | 2014 | World Journal of Gastroenterology2014，20，5： | 8 |
| 3 | Cutaneous perivascular epithelioid cell tumors:A review on an infrequent neoplasm显示文摘'Perivascular epithelioid cutaneous' cell tumors(PEComa) are a family of mesenchymal tumors with shared microscopic and immunohistochemical properties: They exhibit both smooth muscle cell and melanocytic differentiation. Non-neoplastic counterpart of PEComa's cells are unknown, as well as the relationship between extracutaneous PEComa and primary cutaneous ones. We will review the clinical setting, histopathologic features, chromosomal abnormalities, differential diagnosis and treatment options for cutaneous PEComa. | Mar Llamas-Velasco Luis Requena Thomas Mentzel | 2016 | World Journal of Methodology2016，6，1： | 2 |
