Abstract:
Objective To evaluate the diagosis value of different spiral computed tomography(CT) chest scanning methods in the differentiation of various pulmonary diseases,in order to avoid x-ray irradiation damage and reduce patients economic burden,but the diagnosis criterion should be guaranteed still.Methods 1000 cases of chest scan by spiral CT were randomly analyzed.In 927 conventional scan cases,including 155 cases of simple plainscan,474 cases of direct contrast scan,25 cases of plain plus contrast scans,73 cases of CT angiography.In addition,high resolution CT(HRCT) for 105 cases,thin layer scan for 86 cases,dynamic scan for 6 cases,and 40 cases bronchgraphy diagnosis were also carried out in the conventional scanning cases.Results The different CT scanning methods were adapted for diffenent pulmonary diseases.An adaptive scanning method and technique can decrease X-ray irradiation dosage and rise accuracy of diagnosis.Conclusions Aptimal scanning method and technique should be alternative according the clinical need and the patients status.
