| 中文摘要: |
| 目的：探讨肝癌自发性破裂出血的MRI图像特征。方法：对6 例经手术或肝动脉血管造影确诊为原发性肝癌破裂出血患者
的MR图像进行回顾性分析，总结其临床特点及MRI图像特征。结果：6例患者均行MR平扫及增强扫描，肝被膜下出血4例，腹
腔内出血2例。出血表现为T1WI呈高或等信号，T2WI呈高或低信号，5 例可清晰显示肿瘤破口。结论：MR诊断肝癌自发性破裂
出血及时、准确，T1WI及延迟扫描冠状位图像对诊断有定性意义。 |

| Objective: To discuss the MR imaging features of spontaneous ruptured hepatocellular carcinoma（HCC）. Methods:
The MRI findings of 6 ruptured HCC cases which were confirmed by surgery or digital subtraction angiography (DSA) were retrospectively
analyzed. Results: All patients underwent plain and enhanced MR scanning, the liver subcapsular hemorrhage in 4 cases, intraperitoneal
bleeding in 2 cases. Hemorrhage shows higher or equal signal in T1 weight imaging and high or low signal in T2 weight imaging.
The incomplete tumor capsule can be shown in 5 cases. Conclusion: The spontaneous ruptured HCC can be diagnosis through MR imaging
timely and accurately. T1 weight imaging and coronal images in delayed scanning are significant to the diagnosis. |
