The value of CT combined with MRI in the diagnosis of occult cerebral vascular malformation
CT联合MRI诊断隐匿性脑血管畸形的价值探讨

摘要

目的 探讨CT联合MRI诊断隐匿性脑血管畸形的临床价值。方法 在我院收治的隐匿性脑血管畸形患者中，择取2019年01月至2021年12月收治的30例作为研究对象。其在入院时，分别实施CT和MRI检查。然后以术后病理诊断作为参照，来就单一检查方案和联合检查方案的准确性进行统计，并分析该类疾病的影像学特点。结果 在病理检查后，30例患者均确诊为隐匿性脑血管畸形，联合检查的准确率相较于单一检查准确率更高，且MRI检查的准确率相较于CT检查偏高，差异显著（P＜0.05）。在CT检查中，病灶存在不规则斑点、高混杂密度病变等现象，临近皮层有病灶内线条状钙化；在MRI检查中，存在信号复杂化、病灶周围细小血管影等多种现象。结论 CT联合MRI诊断隐匿性脑血管畸形患者，相较于单一检查来说，其诊断准确率更高，且能够通过多个方面来反应患者的脑血管状况，具有较高的推广价值。

Abstract

Objective To explore the clinical value of CT combined with MRI in the diagnosis of occult cerebrovascular malformation.
Methods From January 2019 to December 2021, 30 patients with occult cerebrovascular malformation admitted to our hospital were selected as the research object. On admission, CT and MRI examinations were performed. Then, the accuracy of single examination regimen and combined examination regimen was statistically analyzed with postoperative pathological diagnosis as a reference, and the imaging characteristics of the disease were analyzed.
Results After pathological examination, all 30 patients were diagnosed as occult cerebrovascular malformation. The accuracy of combined examination was higher than that of single examination, and the accuracy of MRI examination was higher than that of CT examination, the difference was significant (P < 0.05). CT examination showed irregular spots, high confounding density lesions, and strip calcification in the adjacent cortex. In MRI examination, there are many phenomena such as complicated signal and shadow of small blood vessels around the lesion.
Conclusion   CT combined with MRI in the diagnosis of occult cerebrovascular malformation patients has higher diagnostic accuracy than single examination, and can reflect the patients' cerebrovascular status through multiple aspects, which has higher promotion value.
