Purpose Wish to search each equipment correlation great damage about ejection fraction, end diastolic volume, end systolic volume that express capacity and function of left ventricle that use multi detector computed tomography(MDCT). Recognized about end systolic phase and suitable section choice of end diastolic phase that is basic information of all-important EDV and ESV in functional analysis. Materials and methods From 560 patients who underwent cardiac MDCT in the Kwangju city C univesity hospital from january, 2008. to january, 2009, We enrolled 39 patients who underwent echocardiogarphy, myocardial perfusion SPECT during the same period for this study. Left ventricular end systolic volume(EDV), left ventricular end diastolic volume(EV) and ejection fraction(EF) were functional analyzed. Results Average volume(47.00±21.46ml, 41.80±13.81ml for 30% and 40% phase, 120.40±34.6ml, 132.40±29.13ml, 137.20±29.83ml for 70%, 80%, 90% phase), average EF(62.41%, 64.93%, 65.91% for 30%(ES), 70%~90% phase(ED), 5.27%, 68.12%, 69.12% for 40%(ES), 70%~90%(ED)) showed significant difference between each phase. Comparing correlation for each parameters between each groups. Average EF(r=0.88, p<0.00001 for MDCT & SPECT, r=0.83, p<0.00001 for MDCT & ECHO, r=0.81, p <0.00001 for SPECT & ECHO) showed high relevance. average EDV(r=0.88, p<0.00001 for MDCT & SPECT, r=0.79, p<0.00001 for MDCT & ECHO, r=0.86, p<0.00001 for SPECT & ECHO) showed high relevance. Average ESV(r=0.88, p<0.00001 for MDCT & SPECT, r=0.79, p<0.00001 for MDCT & ECHO, r=0.86, p<0.00001 for SPECT & ECHO) showed high relevance. Conclusion Qantiative assessment of left ventricular volume and function using 64 slice MDCT Showed high relevance compared with myocardial perfusion SPECT & echocardiogarphy. Hereafter, by technological development of MDCT, if coronary artery stenosis’ diagnosis and left ventricular function analysis consist abuzz, is expected to enforce test more simply because it is to patient.
