背景。与超声心动图相比，心血管磁共振（CMR）具有更高的空间分辨率，但正常测量的评估却落后于其日益增长的临床应用。我们通过 CMR 评估了健康和患病受试者的心房大小，以确定成人的正常范围。方法。对 20 名正常成人和 20 名患有肥厚型或扩张型心肌病的心脏病患者进行了研究。测量并比较四腔和二腔左心房面积以及四腔右心房面积以及左右心房深度，并提出这些测量值的正常范围。结果。正常四腔左心房和右心房收缩面积平均各为 21 cm(2)。平均深度分别为 53 厘米和 52 厘米。对于左心房和右心房，< 24 cm(2) 的收缩面积包括正常范围的上 95 个百分位，并且（特别是对于左心房）最好区分正常心脏和异常心脏。对于心房深度，收缩压值 < 58 cm 可以最好地区分正常与异常，并且还包括正常范围的上 95 个百分位。结论。提出了 CMR 测量的一维和二维左心房和右心房尺寸的正常范围。这些值通常大于超声心动图报告的值。
Background. Cardiovascular magnetic resonance (CMR) has superior spatial resolution compared with echocardiography, but assessment of normal measurements has lagged behind its increasing clinical application. We assessed atrial size by CMR in healthy and diseased subjects to determine normal adult ranges. Methods. Twenty normal adults and 20 cardiac patients with hypertrophic or dilated cardiomyopathy were studied. Four and two chamber left and four chamber right atrial areas and left and right atrial depths were measured and compared, and a normal range for these measures was proposed. Results. Normal four-chamber left and right atrial systolic areas each averaged 21 cm(2). Average depths were 53 and 52 cm, respectively. For both the left and right atrium, a systolic area of < 24 cm(2) included the upper 95th percentile of the normal range and ( especially for the left atrium) best separated normal from abnormal hearts. For atrial depth, a systolic value of < 58 cm best distinguished normal from abnormal and also included the upper 95th percentile of the normal range. Conclusions. Normal ranges for 1- and 2-dimensional left and right atrial size by CMR are proposed. These values are in general greater than those reported for echocardiography.
