【摘要】：目的·探讨头颅磁共振(MRI)平扫脑外意外发现(IECFs)的发生率和漏诊率,评估其临床价值。方法·回顾性分析7 930例因怀疑颅内病变而行头颅MRI平扫的患者头颅MRI平扫资料,分析其IECFs。IECFs按临床意义分为3种类型:E1(无临床意义,如鼻窦黏膜增厚),E2(临床意义可能不大,如咽部对称性增厚),E3(有重要临床意义,如咽部非对称性增厚)。将结构式读片(从上至下按照器官系统逐一进行读片)的结果与初始的MRI报告结果进行比较,计算漏诊率。根据E3类IECFs患者的医疗记录,评价病变的临床意义和转归。结果·在7 930例患者中,发现53.13%的患者5 992处IECFs,其中E1类占82.2%(4 924/5 992),E2类占16.6%(995/5 992),E3类占1.2%(73/5 992)。IECFs和E1类的发现更常见于男性患者(P=0.000,P=0.024)。IECFs在不同的年龄组间比较,差异具有统计学意义(P=0.000)。IECFs总的漏诊率为56.9%(3 409/5 992);E3类IECFs的漏诊率为32.9%(24/73)。73例E3类IECFs患者中,34例(46.6%)患者在研究期间接受最终诊断和适当治疗。结论·在头颅MRI检查的患者中,IECFs普遍存在,近1/3的E3类IECFs可能会漏诊;根据临床价值对IECFs进行分级报告,有助于患者的诊治,减少漏诊。
[Abstract]:Objective to investigate the incidence and missed diagnosis rate of cranial magnetic resonance imaging (MRI) and to evaluate its clinical value. Methods the data of 7 930 patients who underwent MRI plain scan due to suspected intracranial lesions were retrospectively analyzed. According to their clinical significance, IECFs.IECFs was classified into three types: E1 (no clinical significance, such as nasal sinus mucosa thickening and E2). For example, symmetrical thickening of pharynx is of great clinical significance, such as asymmetrical thickening of pharynx. The results of structural reading (from top to bottom according to the organ system) were compared with the results of the initial MRI report, and the missed diagnosis rate was calculated. According to the medical records of E 3 IECFs patients, the clinical significance and outcome of the disease were evaluated. Results 53.13% of the 7 930 patients were found to have 5992 IECFs, of which E1 was 82.2 / 5992C, E2 was 16.6% / 5992% and E3 was 1.2% 73 / 5 992).IECFs and E1 was found to be more common in male patients than in male patients with P0. 000 P0. 024. IECFs were compared among different age groups. The total missed diagnosis rate was 56.9% (3409 / 5992C / E3 IECFs). The missed diagnosis rate of E3 IECFs was 32.9%. 34 of 73 E3 IECFs patients received final diagnosis and appropriate treatment during the study period. Conclusion IECFs are common in patients with cranial MRI, nearly one third of E3 IECFs may be missed diagnosis, according to the clinical value of IECFs classification report, it is helpful to diagnosis and treatment of patients and reduce missed diagnosis.
