AbstractIn this paper, 64-slice spiral computed tomography (CT) retrospective electrocardiographic (ECG) gating technology was used to perform coronary CT angiography scans. The aorta and aortic pulmonary artery diameter were measured quantitatively in healthy people and patients with hypertension and cerebrovascular disease. Corresponding aortic pulmonary artery ratios were obtained through calculation, and the changes of aortic diameter, aortic pulmonary artery ratio, and aortic diameter difference between different cardiac phases, ages, sexes, and levels of hypertension were discussed. Through research, it can be concluded that 64-row spiral CT scan combined with ECG gating technology can accurately measure the dynamic changes of the aortic diameter with the cardiac cycle. At the same time, the aortic diameter measured by multidetector CT scan combined with ECG gating technology and the phase difference between different phases can objectively reflect the degree of arterial damage in patients with hypertension; therefore, early screening of aortic diseases in patients with hypertension can be performed. Diagnosis to detect abnormalities as early as possible and start treatment as early as possible to prevent the disease from progressing and even affecting other tissues and organs can also be obtained.Copyright © 2020 Elsevier Inc.
