为了研究各种MRI信号类型的小肝细胞癌(HCCs)的临床病理学及血管造影特征,作者对115例HCCs进行了MRI检查。男82例,女33例,年龄44～79岁,对术后切除的全部病灶进行病理学检查。115例中61例HCCs直径≤3cm(88个病灶),其中53例(75个)行血管造影。用Signa 1.5T超导磁共振扫描仪,采用多层面多回波技术检查12～16个层面,层厚10mm,层距2.5mm。矩阵256×128～ To investigate the clinicopathological and angiographic features of small hepatocellular carcinoma (HCCs) of various MRI signal types, the authors performed MRI examinations on 115 HCCs. There were 82 males and 33 females, aged 44-79 years old. Pathological examination was performed on all lesions after resection. Of the 115 patients, 61 had a diameter of ≤3 cm (88 lesions), and 53 of them (75) had angiography. Using the Signa 1.5T superconducting magnetic resonance scanner, 12 to 16 layers were inspected using a multilayer multi-echo technique with a layer thickness of 10 mm and a layer spacing of 2.5 mm.
