How to Report a Coronary CT Angiography Michael Poon, MD, FACC

ProcedureCT Angiography of the coronaries with and without contrast was performedusing a 16/32/40/64/128/256­detector CT scanner. Axial images were obtainedfrom the level of the subclavian artery/aortic arch/ascending aorta through tothe diaphragm at 0.6 collimation mm section thickness during breath hold withor without ECG­gated current modulation. 65 ­110 ml of intravenous contrastwas injected via a right/left antecubital intravenous catheter at 4­7 ml/sec with50 ml of (dual flow (30C/70S) or 50 ml of saline saline) infused immediatelyafterward. Image reconstructions were performed at 0.6 mm thickness/0.4interval mm using retrospective cardiac gating. 3D and multiplanarreconstructions were performed. 0­40 mg of Lopressor (+/­ additional calciumchannel blocker) was given intravenously and the heart rate at the time ofimage acquisition was approximately 65 bpm. One dose of 0.4 mgsublingual/sublingual nitroglycerin was given ~5 min prior to the CTA. Theheart rhythm was regular/irregular with/without frequent atrial orventricular premature beats.
