Description
Estimated cost for Coronary CT Angiography at general public hospitals in China is about ¥560-1200, and at Grade 3A hospitals about ¥800-1500, varying by hospital tier and region.
Main Uses
The primary purposes and applicable scenarios for a Coronary CTA include: 1) Evaluating patients with chest pain to rule out coronary artery disease, 2) Assessing the extent and severity of known coronary artery disease, 3) Planning for revascularization procedures like angioplasty or bypass surgery, 4) Follow-up after coronary interventions, 5) Screening for coronary anomalies in asymptomatic individuals with high risk factors.
Normal Range
For a Coronary CT Angiography (CTA), the normal range typically indicates no significant stenosis or blockage in the coronary arteries. The report will usually state that there is less than 50% narrowing of the artery lumen, which is considered within the normal range.
Low Values - Possible Causes
Low values or findings in a CTA, such as underestimation of stenosis, can be due to: 1) Motion artifacts from patient movement during the scan, 2) Inadequate contrast enhancement, 3) Technical issues with the imaging equipment, 4) Very small vessel size making it difficult to accurately assess, 5) Presence of heavily calcified plaques obscuring the true lumen.
High Values - Possible Causes
High values or abnormal findings, indicating more than 50% stenosis, can be caused by: 1) Atherosclerosis, 2) Coronary artery disease, 3) Plaque buildup, 4) Spasm of the coronary arteries, 5) Anomalous origin of a coronary artery.
