Objective To investigate the application value of chest multislice spiral CT(MSCT)in the comparison before and after treatment of high altitude pulmonary edema(HAPE).Methods 50 Chest MSCT and clinical data with the diagnosis of HAPE from January 2019 to October 2022 were collected.HAPE was scored(SHAPE)in chest CT images according to the severity of pulmonary edema.The diameters of the main pulmonary artery(MPA),ascending aorta(AA)and descending aorta(DA)at the same level were measured in chest MSCT before and after HAPE treatment.The ratios of the MPA to AA and DA were calculated,and the differences were compared.Results Before treatment the diameter of the MPA was(3.18±0.38)cm.After treatment the diameter of the MPA was(2.83±0.42)cm.The diameter of the MPA was significantly reduced after treatment compared with that before treatment,with statistical significance(P＜0.05).There were statistically significant differences in the ratio of HAPE patients to the MPA,AA and DA before and after treatment(P＜0.05).SHAPE of HAPE was 11.62±3.57 before treatment and 6.12±4.22 after treatment,and the difference was statistically significant(t=10.978,P=0.00).The SHAPE of the right lung before and after treatment was greater than that of the left lung,and the difference was statistically significant(P＜0.05).Conclusion HAPE chest MSCT showed the lesions of the right lung were more serious than those of the left lung,combined with widening of the MPA.After treatment,the lesions in the lungs were reduced and absorbed in the chest MSCT accompanied by a reduction in the diameter of the MPA.MSCT can be used in the evaluation of HAPE before and after treatment.
