Embodiment

[0019] Sequential selection of 107 inpatients who underwent coronary artery CTA examination in the CT room of Liaocheng People's Hospital from 2017.02.01 to 2017.10.01. The patients were required to be younger than 75 years old, blood pressure 90 / 60mmHg-140 / 90mmHg, BMI value 18-26, heart rate <60 times / min, 14 patients with renal insufficiency were included in the selected patients.

[0020] According to the heart rate, 18ml of contrast agent iopamidol 370 was used to scan and image the coronary artery with CTA. The contrast agent staining of the right atrium was observed with the naked eye, and the scan was performed according to the concentration of contrast agent staining and heart rate. The scanning time is 0.3-0.8s.

[0021] Coronary artery scan was performed with 18ml contrast dose, and the results were as follows: figure 1 as shown, figure 1 Middle, A: ascending aorta CT value 311.2HU; B: left coronary artery (LAD) CT value 292.1HU; C: right coronary artery (RCA) CT v...

Abstract

The invention discloses application of an ultra-low-amount contrast agent in coronary artery imaging of a renal insufficiency patient, and belongs to the field of imaging diagnosis medicine application. The contrast agent is iopamidol 370, and the ultra-low amount is 18 ml. According to the application, the problem that contrast agent-induced nephropathy is easily caused by using a conventional dose (50-70ml) of a contrast agent for coronary artery imaging of general patients with suspicious coronary heart disease and coronary artery imaging of patients with renal insufficiency is effectively solved, and particularly, the influence of the contrast agent on renal function is greatly reduced; and the specific diagnosis and treatment of the coronary heart disease by special patient groups are realized.

Description

technical field [0001] The invention relates to the application of contrast agent in coronary artery imaging, in particular to the application of ultra-low contrast agent in coronary artery imaging of patients with renal insufficiency, and belongs to the application field of imaging diagnostic drugs. Background technique [0002] Millions of people around the world suffer from angina pectoris on a regular basis, even as a disabling disease. Definitive diagnosis and proper management of prognosis in patients with suspected coronary artery disease (CAD) aim to improve and reduce complications. In the diagnosis and treatment of coronary heart disease, how to obtain images of coronary arteries is very critical and important. Only clear and accurate display can facilitate doctors to observe and analyze. So far, coronary angiography based on two-dimensional imaging is still the "gold standard" for diagnosing coronary heart disease. Angiographic image sequences can display dynamic...
