| Abstract | ||||
| Background: One of the most fatal forms of cardiovascular disorder is coronary artery disease(CAD). It is brought on because of the blockage of coronary arteries. For diagnosis of CAD, It’s crucial to evaluate and find the best early detection method. Therefore, the purpose of this study is to assess the absorbed dose by the patient and image quality of two different CT scanners for coronary CT angiography(CCTA): the 256-slice Single PowerCT (SPCT) and the Dual Energy CT (DECT). This study aids in the selection of the most effective CT scanner for CAD diagnosis, providing the best image quality and delivering the least amount of patient dose. Methods: A total number of 30 patients were examined with 256-slice SPCT (group 1), and 30 patients with 192-slice DECT (group 2). A comparison was made between CT Effective Dose& CT Dose Index Volume, to evaluate the effectiveness and reliability of each device. Results: The mean estimated effective radiation dose of for 256-slice single source (first group) and for 192-slice Dual Energy CT (second group) was 33.7± 1.9 and 13.32± 5.1 mSv, respectively. Besides giving less dose than the single source CT, The dual energy CT provided a significantly higher diagnostic image quality and detection reliability. Conclusion: Compared to Single Source CT, CCTA displays lower dosage levels at DECT devices in the diagnosis of CAD. Additionally, DECT produces considerable increase in image quality while delivering a far lower effective dosage in a shorter amount of time than standard single source CT. | ||||
