Liver and spleen volume measurements are important for early detection and monitoring of liver disease. However, alterations in liver and spleen volumes with postural changes, i.e., the different effects of gravity, remain unclear. This study aims to evaluate the effects of posture on the liver and spleen in the supine and upright positions with an original magnetic resonance imaging (MRI) system capable of imaging in any posture (multiposture MRI). The liver and spleen volumes were assessed in ten healthy volunteers (age range: 20-24 years) in the supine and upright positions with multiposture MRI (0.4 T) and compared between postures. The liver and spleen volumes were significantly smaller in the upright position than in the supine position (P < 0.05 for both). Multiposture MRI offers more detailed information on liver and spleen volumes.
肝脏和脾脏体积测量对于肝脏疾病的早期检测和监测至关重要。然而，肝脏和脾脏体积随体位变化（即重力的不同影响）的改变仍不清楚。本研究旨在使用一种能够在任何体位成像的原始磁共振成像（MRI）系统（多体位MRI），评估仰卧位和直立位时体位对肝脏和脾脏的影响。使用多体位MRI（0.4T）对10名健康志愿者（年龄范围：20 - 24岁）在仰卧位和直立位时的肝脏和脾脏体积进行评估，并比较不同体位之间的差异。直立位时肝脏和脾脏体积明显小于仰卧位（两者P均<0.05）。多体位MRI提供了关于肝脏和脾脏体积更详细的信息。
