Application and Clinical Value of 3.0T Magnetic Resonance Whole Heart Coronary Angiography in the Diagnosis of Coronary Artery Stenosis
Abstract
Object: To study the clinical value of 3.0T magnetic resonance whole heart coronary angiography in the diagnosis of coronary artery stenosis.
Method: 38 patients with suspected coronary artery stenosis were randomly selected from our hospital from September 2017 to September 2018. All patients were diagnosed with whole heart coronary angiography by 3.0T magnetic resonance examination. Angiography was adopted as the gold standard to evaluate the value of whole heart coronary angiography via 3.0T magnetic resonance. All the 38 patients have completed the examinations, including 13 segments with grade 0 image quality and 28 segments with grade I image quality. Of 38 patients, 25 underwent coronary angiography, 29 of 25 patients had coronary artery stenosis, while 30 of 25 patients had coronary artery stenosis.The results of 22 coronary stenoses which were confirmed by coronary angiography are consistent with the results obtained from whole heart coronary stenosis by 3.0T MRI. The accuracy, sensitivity, specificity, negative predictive value and positive predictive value of the imaging scheme were 75.86%, 75.86%, 96.67%, 73.33% and 80.00%, respectively.The 3.0T MR whole heart coronary angiography is of outstanding value in the diagnosis of coronary artery stenosis and is worthy of utilization.
