| 目的 探讨软组织血管瘤的MRI和彩色多普勒超声表现,并分析临床应用价值。 方法 对65例经病理证实为软组织海绵状、蔓状血管瘤患者的MRI和彩色多普勒超声图像进行回顾性分析。 结果 海绵状血管瘤在MRI上呈团块或不规则状,呈等T1长T2信号。蔓状血管瘤在MRI上可见多发流空血管影。海绵状血管瘤在超声图像上多为高回声,血流信号丰富,加压时信号显示更为明显,大部分可探及静脉石。蔓状血管瘤在超声图像上多为液性低回声。MRI确诊54例,彩色多普勒超声确诊46例,二者对血管瘤的诊断准确率差异无统计学意义(χ2=2.13,P=0.13)。 结论 海绵状血管瘤和蔓状血管瘤的影像学表现具有特异性;超声可以显示血管瘤内的钙化、静脉石,MRI可显示瘤内的脉管及间质成分,对定性诊断有重要价值。 |

| Objective To assess the value of MRI and color Doppler ultrasonography in the diagnosis of soft tissue cavernous hemangioma (CH) and racemosum hemangioma (RH). Methods MRI and color Doppler ultrasonography findings of CH and RH were evaluated retrospectively in 65 patients with histological confirmation. Results On MRI, CH showed massive or irregular shape, intermediate high signal intensity on T1WI and T2WI. RH showed obvious signal void on both T1WI and T2WI. Color Doppler ultrasonography showed high-level echo with plentiful blood singles inside CH and hemic calculus could be seen in most lesions, and low-level echo with plentiful blood singles was showed in RH lesions. MRI diagnosed 54 patients, and Color Doppler ultrasonography diagnosed 46 patients. No difference of diagnostic accuracy was found between the two methods (χ2=2.13, P=0.13). Conclusion CH and RH have characteristics on MRI and ultrasound images. Ultrasonography can show the calcification and hemic calculus inside the hemangioma, MRI can display the characteristic vascular and fibrofatty structures inside the lesion, both play important role in defining the diagnosis of RH and CH. |
