초록
The purpose of this study was evaluated the relationship between echocardiography and cardiac computed tomography in normal adults by visual assessment, and evaluated the effective doses of cardiac computed tomography. The subjects were 100 normal patients who visited two general hospitals in Chungnam, from January 1 to May 30, 2018. We obtained images by using these modalities and evaluated the wall thickness and internal dimension of the Left Ventricle with visual assessment. To evaluate the appropriateness of the visual evaluation, two evaluators who were trained for one week were measured and the agreement between the evaluators were verified by statistical analysis. The effective doses of computed tomography were evaluated using the dose length product. As a result, there was a high correlation between the two modalities. The agreement between the two visual evaluator were also highly agreed. The mean X-ray dose of the subjects was 11.1±3.1 mSv. Although the purpose of imaging is somewhat different in the clinical setting, echocardiography could achieve the same results as radiation-invasive computed tomography. It is thought that utilization will become even larger.
