Abstract

Objectives To compare Magnetic Resonance (MR) and Computed Tomography (CT) for the assessment of left (LV) and right (RV) ventricular functional parameters. Methods Seventy nine patients underwent both Cardiac CT and Cardiac MR. Images were acquired using short axis (SAX) reconstructions for CT and 2D cine b-SSFP (balanced-steady state free precession) SAX sequence for MR, and evaluated using dedicated software. Results CT and MR images showed good agreement: LV EF (Ejection Fraction) (52+/-14% for CT vs. 52+/-14% for MR; r=0.73; p>0.05); RV EF (47+/-12% for CT vs. 47+/-12% for MR; r=0.74; p>0.05); LV EDV (End Diastolic Volume) (74+/-21 ml/m(2) for CT vs. 76+/-25 ml/m(2) for MR; r=0.59; p>0.05); RV EDV (84+/-25 ml/m(2) for CT vs. 80+/-23 ml/m(2) for MR; r=0.58; p>0.05); LV ESV (End Systolic Volume)(37+/-19 ml/m(2) for CT vs. 38+/-23 ml/m(2) for MR; r=0.76; p>0.05); RV ESV (46+/-21 ml/m(2) for CT vs. 43+ Conclusions Cardiac CT provides accurate and reproducible LV and RV volume parameters compared with MR, and can be considered as a reliable alternative for patients who are not suitable to undergo MR. Key Points Cardiac-CT is able to provide Left and Right Ventricular function. Cardiac-CT is accurate as MR for LV and RV volume assessment. Cardiac-CT can provide accurate evaluation of coronary arteries and LV and RV function.
