目的分析甲亢性心脏病患者心肌灌注显像的影像表现。方法在我院收治的甲亢性心脏病患者中随机抽取38例作为分析对象。对所有患者进行心肌灌注显像检查,对影像结果进行分析,通过6壁段的形式来分析患者是否存在左心室心肌肥厚和显像剂分布减少等现象。结果所有患者心肌灌注显像的影像结果为节段性心肌肥厚和显像剂分布减少,检出率分别为86.84%和65.79%;在显像剂分布减少在前壁出现几率最高,为65.79%;在节段性心肌肥厚在侧壁出现几率最高,为50%。结论甲亢性心脏病患者心肌灌注显像的影像表现普遍为节段性心肌肥厚和显像剂分布减少,其特征表现为多壁段和多病灶,有较高临床研究意义。
Objective To analyze the imaging manifestations of myocardial perfusion imaging in patients with hyperthyroid heart disease. Methods 38 patients with hyperthyroidism admitted to our hospital were randomly selected as the analysis object. Myocardial perfusion imaging was performed on all patients, and imaging results were analyzed. The presence of left ventricular hypertrophy and decreased imaging agent distribution was analyzed by the 6-wall segment. Results Myocardial perfusion imaging in all patients showed segmental myocardial hypertrophy and decreased imaging agent distribution, the detection rates were 86.84% and 65.79%, respectively. The decreased incidence of imaging agents in the anterior wall was the highest (65.79% ; In the segmental myocardial hypertrophy in the sidewall appears the highest probability of 50%. Conclusions Myocardial perfusion imaging in patients with hyperthyroid heart disease is generally characterized by segmental myocardial hypertrophy and decreased distribution of imaging agent, which is characterized by multi-wall segments and multiple lesions, which is of high clinical significance.
