摘要:
目的 分析磁共振成像（MRI）的磁敏感加权成像（SWI）技术在颅内海绵状血管瘤（ICCA）中的诊断效能及影像学征象。方法 选取2021年10月-2022年10月本院收治的90例疑似ICCA患者，对所有患者行常规MRI与SWI检查，以手术病理检查为“金标准”，分析SWI技术在ICCA中的诊断效能及ICCA影像学特征。结果 90例疑似ICCA患者中，手术病理检查结果共检出例38例ICCA，SWI技术共检出37例ICCA，常规MRI共检出30例ICCA；SWI技术检查ICCA的灵敏度为94.74%、准确度为96.63%、阴性预测值为96.15%，高于常规MRI检查的73.68%、86.52%、83.05%，差异有统计学意义（P＜0.05）；Kappa检验显示，SWI技术检查结果与“金标准”检查结果的一致性极好（Kappa值=0.931，P=0.000）。38例经手术病理检查确诊的ICCA患者中，SWI检查呈现完全低信号20例，少数病灶存有相连的小静脉影，与蝌蚪形态相似，称作“蝌蚪”征；呈现为混杂信号18例，病灶内部信号不均匀，称作“爆米花”或“桑葚”样变化；病灶中央高信号，周围绕以低信号，称作“铁环”征；相位图呈现为混杂信号，周围绕以高信号环，称作“光环”征。结论 SWI在ICCA患者诊断中效能良好，可提高疾病的诊断准确率，为临床提供可靠的参考信息，具有较高的应用价值。
Abstract:
Objective To analyze the diagnostic efficacy and imaging signs of magnetic resonance imaging (MRI) susceptibility weighted imaging (SWI) in intracranial cavernous hemangioma (ICCA).Methods A total of 90 patients with suspected ICCA admitted to our hospital from October 2021 to October 2022 were selected. All patients underwent routine MRI and SWI examinations. Surgical pathology was used as the "gold standard" for examination. The diagnostic efficacy of SWI technology in ICCA and ICCA imaging features were analyzed.Results Among the 90 patients with suspected ICCA, 38 ICCA patients were detected by surgical pathological examination, 37 ICCA patients were detected by SWI, and 30 ICCA patients were detected by conventional MRI. The sensitivity, accuracy and negative predictive value of SWI in detecting ICCA were 94.74%, 96.63% and 96.15%, respectively, which were higher than 73.68%, 86.52% and 83.05% of conventional MRI, and the differences were statistically significant (P<0.05). Kappa test showed that the results of SWI were in good agreement with the results of "gold standard" (Kappa value=0.931, P=0.000).Among the 38 ICCA patients confirmed by surgical and pathological examination, 20 patients showed complete low signal on SWI examination, and a few lesions had connected small venous shadows similar to tadpole morphology, known as the "tadpole" sign; 18 patients showed mixed signals, with uneven internal signals within the lesion, known as "popcorn" or "mulberry" like changes; the lesion was characterized by high signal intensity in the center and low signal intensity surrounding it, known as the "iron ring" sign; the phase diagram presents as a mixed signal surrounded by a high signal loop, known as the "halo" sign.Conclusion SWI has good efficacy in the diagnosis of ICCA patients, which can improve the diagnostic accuracy of the disease, provide reliable reference information for clinical practice, and has high application value.
