The increased diagnostic usefulness of multiplane over biplane transesophageal echocardiography has not yet been conclusively determined. In this study the diagnostic yield of multiplanar and biplanar imaging was compared blindly by using the information content obtained from multiplane transesophageal echocardiography to that derived from biplanar type of imaging planes available in the multiplane echocardiography recordings in 80 patients with a variety of cardiac disorders. Among these patients 9 new abnormalities were identified by multiplane transesophageal echocardiography in 8 patients. Multiplane imaging yielded better delineation of 40 various lesions in 31 patients. Thus multiplane transesophageal echocardiography has a greater diagnostic yield than biplane imaging by depicting more lesions in 10% of patients and by enhanced delineation of the extent of pathologic characteristics in 39% of patients. This versatility, coupled with the ease of obtaining a vast assembly of imaging planes without undue probe manipulations, makes multiplane transesophageal echocardiography more useful than biplanar imaging.
多平面经食管超声心动图相较于双平面经食管超声心动图在诊断方面的更高实用性尚未得到最终确定。在本研究中，对80例患有各种心脏疾病的患者，通过比较多平面经食管超声心动图所获信息与双平面成像（从多平面超声心动图记录中可用的双平面成像平面得出），对多平面成像和双平面成像的诊断率进行了盲法比较。在这些患者中，多平面经食管超声心动图在8例患者中发现了9个新的异常情况。多平面成像对31例患者的40种不同病变进行了更好的描绘。因此，多平面经食管超声心动图比双平面成像具有更高的诊断率，它在10%的患者中发现了更多病变，并在39%的患者中更清晰地描绘了病理特征的范围。这种多功能性，再加上无需过度操作探头就能轻松获得大量成像平面，使得多平面经食管超声心动图比双平面成像更有用。
