摘　　要：BACKGROUND With very high mortality and disability rates,cerebrovascular diseases and intracranial tumors severely threaten the health and fighting strength of flying personnel,requiring great concern and intensive screening in clinic,early warning in an early and accurate manner and early intervention of diseases possibly resulting in inflight incapacitation are key emphases of aeromedical support in clinic.AIM To probe into the spectra of intracranial diseases,flight factors and medical imaging characteristics of military pilots(cadets)in the physical examination for transfer to pilot modified high performance aircraft,thus rendering theoretical references for clinical aeromedical support of pilots.METHODS A total of 554 military pilots(cadets)undergoing physical examination for transfer to pilot modified high performance aircraft from December 2020 to April 2024 in a military medical center were enrolled in this study.Then,a retrospective study was carried out on intracranial disease spectra and head magnetic resonance imaging(MRI)data of 36 pilots(cadets)who were unqualified for transfer to pilot modified high performance aircraft.Besides,a descriptive statistical analysis was conducted on the clinical data,age,fighter type and head MRI data of such pilots(cadets).RESULTS Abnormal head images were found in 36 out of 554 pilots(cadets)participating in the physical examination for transfer to pilot modified high performance aircraft,including arachnoid cyst in 17(3.1%)military pilots(cadets),suspected very small aneurysm in 11(2.0%),cavernous hemangioma in 4(0.7%),vascular malformation in 2(0.4%),and pituitary tumor in 3(0.5%,one of which developed cavernous hemangioma simultaneously).Among the 17 pilots(cadets)with arachnoid cyst,4 were identified as unqualified for transfer to pilot modified high performance aircraft because the marginal brain tissues were compressed by the cyst>6 cm in length and diameter.The 11 pilots(cadets)with suspected very small aneurysms identified by 3.0T MRI consisted of 6 diagnosed
