| 摘 要： | 目的探讨螺旋CT及高场强MRI对肝孤立性坏死结节（SNNL）的诊断价值。方法回顾性分析8例经病理证实的肝孤立坏死结节的CT及MRI表现。结果 CT平扫病灶均为低密度影,增强动脉期及门脉期均未见明显强化,延迟期部分病例轻度强化。MRI T1WI病变呈等或略低信号,T2WI病变呈略高到中高信号,增强各期均无强化。结论多层螺旋CT及高场强MRI扫描均能很好的反映SNNL的病理学特点,可以提高SNNL的诊断准确性。

| Abstract: | 【Objective】To explore the value of spiral CT and high field MRI in the diagnosis of solitary necrotic nodule of liver.【Methods】CT and MRI images of 8 patients with surgically and pathologically confirmed Solitary necrotic nodule of the liver.【Resluts】Plain CT scan showed low density shadow, enhanced arterial phase and portal venous phase were no obvious enhancement, some cases mild enhancement of delayed phase enhancement.MRI T 1 WI lesions showed equal or slightly low signal, T 2 WI lesions were slightly high to high signal, enhance the showed no enhancement. 【Conclusion】 Multi slice spiral CT and high field MRI scan can well reflect thepathological features of SNNL, can improve the diagnostic accuracy of SNNL. |
