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/m² for CT vs. 76  ±  25 ml/m² for MR; r  =  0.59; p > 0.05); RV EDV (84  ±  25 ml/m² for CT vs. 80  ±  23 ml/m² for MR; r  =  0.58; p > 0.05); LV ESV (End Systolic Volume)(37  ±  19 ml/m² for CT vs. 38  ±  23 ml/m² for MR; r  =  0.76; p  >  0.05); RV ESV (46  ±  21 ml/m² for CT vs. 43  ±  18 ml/m² for MR; r  =  0.70; p  >  0.05). Intra- and inter-observer variability were good, and the performance of CT was maintained for different EF subgroups.

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.
