It's for a time strange that the entity claiming to be a doctor seem to be answering a completely different sound out than the one you asked, Badius, but I will try to clear things up.
Loving_Heart's answer is in mention to bile duct disease and not coronary disease. It's intricate for anyone to say-so that coronary CT angiogram is "better" or "more reliable" than traditional coronary angiography because the studies that enjoy be published almost universally use traditional coronary angiography as the "gold ingots standard". The exactness of coronary CT is and so usually given within quotation to coronary angiography.
The studies that own be published suggest that 64-slice CT have a sensitivity of 93-100%, specificity of 90-95%, and positive and denial predictive values of 75-85% and 95-100%, respectively, for detecting significant coronary stenoses. In other words, CT angiography is a pretty moral check and will probably draw from better. Right immediately, it is a bit better at recitation us who DOESN'T hold coronary disease than who does, and it is much smaller quantity nifty surrounded by culture who hold stents or bypasses.
Invasive is the best solution as contained by baggage of bile duct the let cannot be see on Sonogram, so a verbs is passed to check its patency.
This interrogate be Put up contained by FRCS and several candidate flunked adjectives ticked Sonogram.
No. An invasive coronary angiogram is the gold ingots standard for visualize the coronary vessel.
The picture of a CT angio is recurrently obscured by artefact cause by calcium surrounded by the vessel, by chest movement of the patients, etc. Current facts have proven that the reproducibility of the invasive angio is markedly more than that of the CT angio.
That said, if a long-suffering of mine have low probability of coronary heart disease but complains of cardiac sounding chest pains next to a usual ECG/stress trial, I would be tricky pressed to transport him for an invasive angio and would opt instead for a CT angio.
Each have its place within clinical admin of culture near heart disease.
