The value of plate thermography in the determination of placental localization was investigated in 120 cases, and compared with the results obtained by the ultrasonic B-Scan method. The duration of pregnancy in these cases ranged from 15 to 37 weeks. The results of plate thermography corresponded with ultrasonic localization in 94 cases (78.3%), but the placenta was incorrectly localized by plate thermography in 26 patients. The highest degree of correspondence was observed in the group of anterior wall placentae, the localisation of the placenta by plate thermography being correct in 52 out of 62 cases. The group of posterior wall placentae showed the lowest rate or correspondence, plate thermography giving the correct localization in only 32 out of 45 cases. Hence, plate thermography does not appear to be of sufficient accuracy for clinical use or scientific investigations. Furthermore, no accurate determination of placental surface area and placental thickness is possible with plate thermography. For all these reasons it may be concluded that this method is greatly inferior to the ultrasonic B-Scan method in respect to placental localization.
对120例患者进行了平板热成像在确定胎盘定位方面的价值研究,并与超声B超扫描法所得结果进行了比较。这些病例的孕周为15至37周。平板热成像结果与超声定位相符的有94例(78.3%),但有26例患者平板热成像对胎盘的定位有误。在前壁胎盘组中观察到的相符程度最高,62例中有52例平板热成像对胎盘的定位正确。后壁胎盘组的相符率最低,45例中只有32例平板热成像定位正确。因此,平板热成像对于临床应用或科学研究而言,准确性似乎不足。此外,平板热成像无法准确测定胎盘表面积和胎盘厚度。基于所有这些原因,可以得出结论,在胎盘定位方面,该方法远不如超声B超扫描法。
