利用直立式磁共振成像(MRI)对盆腔器官脱垂进行量化是一个很有前途的研究领域。这项研究确定了患者直立姿势下骨盆倾斜矫正系统(PICS)的角度，该角度假设偏离仰卧位PICS角度。还将讨论不同患者体位不同PICS角度的必要性。对113例患者直立体位的女性进行磁共振扫描，以确定直立的PICS角，定义为骶尾部-耻骨下点(SCIPP)线与水平线之间的夹角。用配对t检验和皮尔逊相关系数(R)分别计算直立和仰卧PICS角之间的差异和相关性。用测角法计算直立和仰卧PICS角的差异对测量的盆腔器官范围的影响。直立位平均PICS角29°(26~35°)，仰卧位平均33°(30~37°)。它们有显著差异(p<；0.001)，且相关性非常强(r=0.914，p<；0.001)。平均直立和仰卧PICS角度之间的4°差异导致直立扫描患者测量的宫颈高度平均低估了约0.5厘米。患者直立体位的PICS角为29°。对于不同的患者体位，使用专用的PICS角度可以对脱垂患者的盆腔器官范围进行更准确的分析。
Pelvic organ prolapse quantification by means of upright magnetic resonance imaging (MRI) is a promising research field. This study determines the angle for the pelvic inclination correction system (PICS) for upright patient position, which is hypothesized to deviate from the supine PICS angle. The necessity of different PICS angles for various patient positions will also be discussed. Magnetic resonance scans of 113 women, acquired in an upright patient position, were used to determine the upright PICS angle, defined as the angle between the sacrococcygeal–inferior pubic point (SCIPP) line and the horizontal line. The difference and correlation between the upright and supine PICS angles were calculated using the paired Student’s t-test and the Pearson’s correlation coefficient (r) respectively. The effect of the difference between the upright and supine PICS angle on the measured pelvic organ extent was calculated using goniometry. The mean (interquartile range) PICS angles were 29° (26–35°) for the upright and 33° (30–37°) for the supine patient position. They were significantly different (p<0.001) and very strongly correlated (r = 0.914, p<0.001). The 4° difference between the average upright and supine PICS angle results in an average underestimation of the measured cervix height of approximately 0.5 cm for patients scanned in upright position. The PICS angle for the upright patient position is 29°. The use of a dedicated PICS angle for different patient positions allows for more accurate pelvic organ extent analysis in patients with prolapse.
