ABSTRACT

Objective To investigate the diagnostic value of helical CT study in pulmonary thromboembolism.Methods A retrospective analysis was made on 16 misdiagnosed cases,studied previously with plain CT scanning.Results All of the 16 cases had positive findings on CT scanning,with sensitivity 100%.Among them,11 cases were misdiagnosed as pleural effusion plus pneumonia;3 pleural effusion;and 2,each of organized pneumonia and peripheral lung cancer.Conclusion The strong evidence of the disease could be given even with plain CT studies.The procedure is simple,safe and reliable,If a patient is suspected with the disease,and if CT is available in the hospital,CT should be the first choice in the study.
