作者为研究肝脏转移瘤MR成像上病灶周边强化与组织病理学结果之间的联系,选择7例符合下列标准的肝转移瘤病人:①已切除肝转移瘤及周围肝实质。②在一个月之内完成MR检查和手术。③在行MR检查至手术期间未接受过介人治疗,包括化疗。男4例,女3例,年龄41～71岁,平均56.1岁。转移瘤来自结肠直肠癌(n=5)、胰腺神经内分泌肿瘤(n=1)及膀胱移行细胞癌(n=1)。对于有多个转移灶的病例,仅测量最大的一个病灶。作者应用
In order to study the relationship between peripheral lesion enhancement and histopathological findings on MR imaging of liver metastases, we selected 7 patients with hepatic metastases who met the following criteria: 1 Liver metastases and surrounding liver parenchyma were removed. 2 Complete MR examination and surgery within one month. 3 During the period of MR examination to surgery, no intercourse treatment was included, including chemotherapy. There were 4 males and 3 females aged 41-71 years with an average age of 56.1 years. Metastatic tumors were from colorectal cancer (n=5), pancreatic neuroendocrine tumors (n=1), and bladder transitional cell carcinoma (n=1). For cases with multiple metastases, only the largest lesion was measured. Author application
