Iodine-123 MIBG is a norepinephrine analog which can be used to image the sympathetic innervation of the heart. The authors report a patient with myotonic dystrophy whose I-123 MIBG SPECT revealed accelerated washout of I-123 MIBG from infero-posterior and a part of lateral wall, although Tl-201 SPECT showed no abnormal finding. The authors conclude that I-123 MIBG can be more sensitive in detecting the cardiac abnormality than Tl-201 SPECT in this disease.
碘-123间碘苄胍(I-123 MIBG)是一种去甲肾上腺素类似物,可用于对心脏的交感神经支配进行成像。作者报告了一名患有强直性肌营养不良的患者,其I-123 MIBG单光子发射计算机断层扫描(SPECT)显示下后壁和部分侧壁的I-123 MIBG洗脱加速,尽管铊-201(Tl-201)SPECT未显示异常发现。作者得出结论,在这种疾病中,I-123 MIBG在检测心脏异常方面比Tl-201 SPECT更敏感。
