| Abstract |
To correlate the left ventricular parameters obtained with 64-slice Volumetric Computed Tomography (VCT) with those obtained with the reference standard, cardiovascular magnetic resonance (CMR) imaging. VCT and a 3.0T MRI scanner were used. Results from both studies were independently evaluated by two cardiologists. A linear correlation and a paired Student's t test were used to analyze the data with a P<0.05 being considered significant. Thirty consecutive patients were evaluated with VCT and CMR. The left ventricular indices for CMR and VCT were, respectively, mass 86.4±25.8 vs. 82.7±27.6g (P=0.31); ESV 45.5±27.8 vs. 48.7±40.4ml (P=.405); EDV 101.3±32.7 vs. 105.1±44.0ml (P=0.475); SV 55.9±16.1 vs. 56.8±15.6ml (P=0.713); LVEF 57.5±13.2% vs. 56.9±12.4% (P=0.630). No differences in intraobserver variability for both methods were found, CT r=0.96, r(2)=0.92 P<0.0001 and MR r=0.96 r(2)=0.93 P<0.0001. There was no significant statistical difference in the presence of artifacts. There is a close correlation between CMRI and VCT in the evaluation of LV function. VCT is as useful as 3T CMR, and could be incorporated as another resource for evaluating LV function. |
