Hybrid cardiac magnetic resonance/computed tomographic imaging: first fusion of three-dimensional magnetic resonance perfusion and low-dose coronary computed tomographic angiography.

摘要

A 65-year-old male patient with typical chest pain underwent low-dose coronary computed tomo-graphic (CT) angiography (CCTA) with 1.4 mSv for evaluation of coronary artery disease (CAD). Panel A shows a curved multiplanar reformation of the left circumflex artery with a high-grade stenosis (white arrow) in the large first obtuse marginal branch (OM1). Subsequently, a stress cardiac magnetic resonance perfusion imaging (CMR) (adenosine 140 |Ag/kg/min, 0.1 mmol/kg Gadobutrolum, kt-SENSE) was performed with a new sequence allowing three-dimensional (3D) perfusion assessment.
