英文摘要	Conference Name:2013 International Conference on Bio-Medical Materials and Engineering, ICBME 2013. Conference Address: Hong Kong, China. Time:March 26, 2013 - March 27, 2013.; Doing the heart three-dimensional CT imaging (3DCT), the writers found 3DCT can clearly show the left ventricular apical thinning (LVAT). Purpose: To observe the shape of LVAT and measure related parameters in the end-systolic and end-diastolic phases. Methods: 12 cadaveric heart specimens were observed, and the thickness of LVAT was measured, as well as the thickest myocardium of left ventricle (TMLV). There are 69 cases imaging data of the end-systolic and end-diastolic phases without heart diseases from PACS in our hospital, with multiplanar reconstruction (MPR), Volume rendering (VR), the LVAT was clearly shown and measured. Measuring parameters include the thickness of LVAT, TMLV and the distance between the LVAT and the anterior descending branch of left coronary artery (DBLCA). Statistical comparisons were made. Results: In all cadaveric heart specimens of 12 cases were found the LVAT, the thickness of LVAT, TMLV was 1.74 mm ± 0.32 mm, 13.07 mm ±1.48 mm. 3DCT clearly showed the LVAT in the 69 cases, whose thickness was 1.17 mm ± 0.43 mm in the diastole phase and 1.19 mm ± 0.48 mm in the systole phase. The thickness of TMLV was 12.02 mm ± 1.66mm, and the distance between the LVAT and DBLCA was 13.70mm ± 3.78 mm in the diastole phase. There were not significant differences in the LVAT thickness between systole and diastole phases (t = 0.366, p > 0.5), but there are significant differences in measuring the thickness of myocardium between the anatomy and 3DCT (t = 2.210, 0.01< P<0.05). Conclusion: The LVAT can be clearly shown by anatomy and 3DCT, and its thickness does not change in the end-systolic and end-diastolic phases. ? (2013) Trans Tech Publications, Switzerland.
