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中选出。因
pancreas CT segmentationAccurate pancreas segmentation is critical for the diagnosis and management of diseases of the pancreas. It is challenging to precisely delineate pancreas due to the highly variations in volume, shape and location. In recent years, coarse-to-fine methods have been widely used...

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...
目前大多数胰腺癌的诊断是依赖其临床表现(腹痛、黄疸、体重下降、腹块等)、腹部B超或CT及血清CA19-9测定等检查。如CT检查结果不典型或正常,但仍有可疑者,可进一步通过经皮肝穿刺胆道造影(PTC)、内腔镜逆行胰胆管造影(ERCP)、经皮胰腺肿物穿刺活检(FNA)等检查以明确诊断。分期上由于TNM分期不能准确反映患者的治疗...
