- “In patients scheduled to undergo noncoronary cardiovascular surgery, coronary CT angiograms are of diagnostic image quality in 81% of cases.”
Ruling Out Coronary Artery Disease with Noninvasive Coronary Multidetector CT Angiography before Noncoronary Cardiovascular Surgery
Catalan P et al.
Radiology 2011; 258:426-434 - “ The presence of severe coronary artery calcification is the only independent predictor of nondiagnostic coronary CT angiography: an Agaston score of about 600 shows the best predictive accuracy for performing diagnostic coronary CT angiography.”

Catalan P et al.
Radiology 2011; 258:426-434 - “ In nonselected patients scheduled to undergo noncoronary cardiovascular surgery, preoperative coronary CT angiography was diagnostic in 81% of cases. Preoperative ICA could be safely avoided in patients without significant CAD by using coronary CT angiography. The Agaston score, but not the presence of atrial fibrillation, was an independent predictor of nondiagnostic coronary VT angiography.”

Radiology 2011; 258:426-434 "Triple rule-out CT is feasible in patients with suspicion of PE, reveals a wide range of vascular and non-vascular chest disease, and offers an excellent overall diagnostic performance."
