目的：建立由当前脉冲序列确定的左心室（LV）和右心室（RV）尺寸的正常范围。在心脏磁共振成像（MRI）。材料。和方法：对60名正常受试者（30名男性和30名女性;年龄范围，20-65岁）进行了检查;涡轮梯度回波（TGE）和稳态自由旋进（SS，FP）脉冲序列均用于获得从心室心尖到心脏底部的连续短轴电影数据集。采用改良辛普森规则计算左心室、右心室容积和左心室质量。结果：建立了正常范围，并以体表面积（BSA）和身高为指标。有统计学显着差异的测量之间的性别和TGE和SSFP脉冲序列。对于TGE，男性的LV舒张末期容积（EDV）/BSA（mL/m2）为74.4 +/- 14.6，女性为70.9 +/- 11.7，而在SSFP中，男性为82.3 +/- 14.7，女性为77.7 +/- 10.8。对于TGE，男性的LV质量/ BSA（g/m（2））为77.8 +/- 9.1，女性为61.5 +/- 7.5，而在SSFP中，男性为64.7 +/- 9 3，女性为52.0 +/- 7.4。对于TGE，RV EDV/BSA（mL/m2）在男性中为78.4 +/- 14.0，在女性中为67.5 +/- 12.7，而在SSFP中，男性为86.2 +/- 14.1，在女性中为75.2 +/-13.8。我们提供了性别特异性的正常范围以及可用于SSFP和TGE脉冲序列的年龄特异性正常范围的数据。
Purpose: To establish normal ranges of left ventricular (LV) and right ventricular (RV) dimensions as determined by the current pulse sequences. in cardiac magnetic resonance imaging (MRI).Materials. and Methods: Sixty normal subjects (30 male and 30 female; age range, 20-65) were examined; both, turbo gradient echo (TGE) and steady-state free precession (SS,FP) pulse sequences were, used to obtain contiguous short-axis cine data sets from the ventricular apex to the base of the heart. The LV,and RV volumes and LV mass were calculated by modified Simpson's rule.Results: Normal ranges were established and indexed to both body surface area (BSA) and height. There were statistically significant differences in-the measurements between the genders and between TGE and SSFP pulse sequences. For TGE the LV end-diastolic volume (EDV)/BSA (mL/m(2)) in males was 74.4 +/- 14.6 and, in females was 70.9 +/- 11.7, while in SSFP in males it was 82.3 +/- 14.7 and in females it was 77.7 +/- 10.8. For the TGE the LV mass/ BSA (g/m(2)) in males was 77.8 +/- 9.1 and in females it was 61.5 +/- 7.5, while in SSFP in males it was 64.7 +/- 9 3 and in females it was 52.0 +/- 7.4. For TGE the RV EDV/BSA (mL/ m(2)) in males was 78.4 +/- 14.0 and in females it was 67.5 +/- 12.7, while in SSFP in males it was 86.2 +/- 14.1 and in females it was 75.2 +/- 13.8.Conclusion: We have provided normal ranges that are gender specific as well as data that can be used for age-specific normal ranges for both SSFP and TGE pulse sequences.
