This study aims to compare the apparent diffusion coefficients (ADCs) and proton magnetic resonance spectroscopy ((1)H-MRS) in the first 24 h of acute hypoxic-ischemic brain damage (HIBD) in piglets. Twenty-five 7-day-old piglets were subjected to transient bilateral common carotid artery occlusion followed by ventilation with 4% oxygen for 1 h.(More)
We analyzed the clinicopathological features of 9 breast malignant fibrous histiocytoma (MFH) patients. Immunohistochemistry was used to make both diagnosis and differential diagnosis, and to identify prognostic factors. All tumors lacked epithelial markers but expressed mesenchymal markers, suggesting a mesenchymal origin. Of the five cases expressing(More)
Ovarian yolk sac tumors (YSTs) are rare neoplasms. No radiological study has been done to compare the imaging findings between this type of tumor and other ovarian tumors. Here we analyzed the CT findings of 11 pathologically proven ovarian YSTs and compared their imaging findings with 18 other types of ovarian tumors in the same age range. Patient age,(More)
Homogeneous target dose distribution in intensity-modulated radiotherapy (IMRT) for sinonasal cancer (SNC) is challenging to achieve. To solve this problem, we established and evaluated a basal-dose-compensation (BDC) optimization approach, in which the treatment plan is further optimized based on the initial plans. Generally acceptable initial IMRT plans(More)
