The Multislice CT Angiography Center at Jam Hospital offers the following diagnostic services and responsibilities to the esteemed clients:
The veins that supply blood to the heart muscle are called coronary arteries. These vessels may be narrowed by an object called plaque, which contains a number of cells, fatty deposits (cholesterol) and sometimes calcium, which reduce blood flow. The rupture or clotting of one of these plaques results in a sudden occlusion of the vein and myocardial infarction.
Coronary CT angiography is a new non-invasive procedure that is gradually replacing invasive coronary angiography in the world. In this method, 3D images are taken of your veins through X-ray within 15 minutes to determine if your veins are narrowing. In the case of stenosis, the exact location and extent are determined.
Comparing Diagnostic Ability of CT Angiography with Invasive Angiography
As discussed earlier, CT angiography provides comprehensive and practical information on vascular anatomy, the presence of congenital vascular anomalies, and the involvement manner of the affected vein. In addition, CT angiography adequately reveals the connection between congenital and acquired vascular anomalies such as aneurysm (abnormal vein dilation), dissection (internal aortic wall rupture), vascular shunts (abnormal connections between coronary arteries and veins or heart chambers), cardiac shunt including atrial septal defect (ASD), ventricular septal defect (VSD), and patent ductus arteriosus (PDA).
Comparing Diagnostic Ability of CT Angiography with other Non-Invasive Cardiovascular Methods
• Cardiac stress test has a sensitivity of 63%, a diagnostic ability of 74%, and about 25% of false positive and false negative cases.
• Nuclear medicine diagnostic methods such as thallium heart scan have a sensitivity of 85% and a specificity of 81%.
• Pharmacological diagnostic methods such as stress echocardiogram have a sensitivity of 85% and a specificity of 88%.
The sensitivity of MSCT coronary angiography is between 93% -97% and its specificity is 94% for diagnosis and screening of coronary artery disease and other vascular diseases, which is the highest among all non-invasive cardiovascular methods.
