| Research Abstract |
To improve cardiovascular CT imaging workflow, we developed an interpretation support system. The system can record information regarding the disease location, nature of the plaque, and presence or absence of calcification. In addition, we developed image classification method utilizing DICOMTag to help radiologists to choose images for reading. To investigate whether a newly developed support system could reduce the time taken by radiologists to read coronary artery CT images, as well as to improve diagnostic accuracy, a total of 20 studies including 10 initial and 10 follow-up CT were reviewed by two readers. As a result, the reading time for both readers was reduced by 20%. The diagnostic concordance rate for disease location was increased from 92% to 100%.
