摘　　要：目的:探讨放射性核素心室造影在评估右心室收缩功能准确性的应用价值。方法:选择30例本院住院病人,其中包括冠心病12例,高血压病8例,心肌病4例,肺动脉高压6例。分别经核磁共振(MRI)和放射性核素心室造影(SPECT)测量其右心室舒张末期容量(RVEDV),RVESV和右心室射血分数(RVEF),比较SPECT和MRI的相关性。结果 SPECT测得RVEDV数值(106.01±51.40)ml与MRI组(128.60±64.05)ml相比较,差异有统计学意义(t=3.36,P<0.05);SPECT测得RVESV和RVEF值与MRI组相比较,差异无统计学意义(P>0.05)。SPECT与MRI测得的RVEDV、RVESV和RVEF具有相关性(rEDV=0.622,rESV=0.570,rEF=0.538)。结论:SPECT核素心室造影可更为准确评估右心室收缩功能。Objective To explore the value of the application of single-photon emission computed tomography （SPECT） in evalu- ating the accuracy of systolic function of right ventricle. Methods 30 patients which contained coronary artery disease 12, hypertension 8, cardiomyopathy 4, pulmonary hypertension 6 underwent SPECT and MRI, then the RV end-diastolic volume （ RVEDV）, RV end-systolic volume（RVESV） ,and RV ejection fraction（RVEF） were measured. Results Compared with those in the MRI group, patients in the SPECT group manifested lower RVEDV, which was significantly different according to t-test （t = 3.36, P 〈 0.05）. The RVESV and RVEF values in the two groups showed no more difference. SPECT have a correlation with MRI in RVEDV, RVESV and RVEF（ rEDV = 0. 622, rESv = 0. 572,rEF = 0. 538）. Conclusion SPECT can assess right ventrieular systolic function accurately.
