Pancreas-CT 数据集包含 80 例(53名男性,27名女性)对比增强(静脉注射对比剂后约70秒在门静脉期进行)的 3D CT扫描,并且提供对胰腺的手工标注。数据集由美国国立卫生研究院临床中心提供,其中17名受试者是健康的肾脏捐献者在肾切除术前接受了扫描。其余65名患者由放射科医生从既无重大腹部病变又无胰腺癌病灶的患者...
MSD Pancreas Tumour 数据集是 MSD (Medical Segmentation Decathlon, 医学图像分割十项全能挑战赛) 中的 Task07 即第 7 个子任务,目标是从 CT 图像中分割出胰腺和肿瘤,MSD 选择该数据集的原因是“标签不平衡,其中包括大(背景)、中(胰腺)和小(肿瘤)结构”。胰腺肿瘤分割也是 MSD 最难的两项任务之一(另一个是...
PURPOSE: To describe the computed tomographic (CT) findings of ectopic pancreas and to identify the features that differentiate it from other similarly manifesting gastric submucosal tumors such as gastrointestinal stromal tumor (GIST) and leiomyoma, which are the most common gastrointestinal submucosal tu...
Abdominal CT showed a solid nodular lesion in the third portion of the duodenum, the presence of retropancreatic, aortic and caval lymph nodes, and four nodular splenic masses. 111In-octreotide scintigraphy revealed pathological tissue accumulation in the duodenal region, and in the retropancreatic,...
To identify the CT features in differentiating grade 3 neuroendocrine carcinomas from grade 1/2 neuroendocrine tumours.This study included 161 patients with surgically confirmed pancreatic neuroendocrine neoplasms. Pathology slides were reviewed to determine the tumour grade. CT image analysis included size...
We present a fully-automated bottom-up methodfor pancreas segmentation in computed tomography (CT) images of the abdomen.The method is based on hierarchical coarse-to-fine classification of localimage regions (superpixels). Superpixels are extracted from the abdominalregion using Simple Linear Iterative...
CT scan showed a tumor in the pancreas with secondaries in the liver, peri-pancreatic lymph nodes, vertebral bone marrow and subcutaneous tissue of the ... Chetty,S P,Clark,... - 《Pathology》 被引量: 70发表: 1993年 Light- and electron-microscopic study of synaptic connections in the par...
The tumor had central necrosis, which was poorly perfused on contrast-enhanced computed tomography (CT) and which had a high intensity on T2-weighted magnetic resonance imaging (MRI). Histology revealed the lesion to be a solid pseudopapillary tumor of the pancreas, with the characteristic pseudo...
Purpose We propose an automated pancreas segmentation algorithm from contrast-enhanced multiphase computed tomography (CT) and verify its effectiveness in segmentation. Methods The algorithm is characterized by three unique ideas. First, a two-stage segmentation strategy with spatial standardization of pancre...
