Abstract:
Objective:To investigate the distribution of diseases in Air Force pilots by cranial MRI examination.Methods:Four hundred and twenty-four pilots were checked cranial MRI plain examination, magnetic resonance angiography (MRA) and susceptibility weighted imaging (SWI). The results of 424 pilots′ disease spectrum were statistically analyzed. The pilots were divided into 4 groups according to age: 20-30 years group, 31-40 years group, 41-49 years group and ≥50 years group. The positive detection rates of white matter hyperintensities (WMHs) among these groups were analyzed and compared.Results:The number of positive pilots during cranial MRI examination was 134 and the positive rate was 31.6%, of which 9 pilots had 2 kinds of lesions at the same time. The main diseases of 134 pilots were WMHs (24.29%), intracranial calcification (1.89%), arachnoid cyst (1.89%), venous malformation (1.65%), aneurysm (1.18%), moyamoya disease (0.71%), pituitary cyst (0.47%), cavernous hemangioma (0.47%), remote hemorrhage (0.24%), encephalomalacia foci (0.24%), intraventricular benign tumor (0.24%), pineal cyst (0.24%), choroid plexus cyst (0.24%). The differences of WMHs detection rates among different age groups were statistically significant ( χ2=86.457, P<0.01). Conclusions:Some potential cranial diseases of pilots could be found by MRI examination. Cranial MRI examination is very important in pilots′ physical examination.
