摘要
在许多特殊的临床条件下或在泌尿系统疾病的治疗或管理过程中,持续准确地监测膀胱容量是非常重要的。本研究试图通过基于磁共振成像(MRI)的重建膀胱三维模型,探索膀胱的动态储存过程,了解特定饮水条件下膀胱形状和膀胱内体积的变化。使用3T GE MRI系统获取膀胱图像,同时存储在横切面上。利用Mimics软件对膀胱MRI图像进行分割、三维模型重建和不同扫描阶段的体积测量。结果表明,膀胱在储尿过程中由小碗状变为不规则椭球状。在特定的饮水条件下,膀胱体积的增加是非线性的。尿潴留过程中不同方向膀胱直径变化不一致。
The Study of Nonlinear Change of Bladder During Urinary Store Based on MRI
It is significant to monitor bladder volume continuously and accurately in many specific clinical conditions or during treatment or management of urological disorders. This study try to explore the dynamic bladder storing process and understand the change of bladder shape and intra-vesical volume under the specific conditions of water-drinking using reconstructed three-dimension (3D) bladder models based on magnetic resonance imaging (MRI). A 3T GE MRI system was used to acquire bladder images while storing in the transverse section. Segmentation of the bladder MRI Image, 3D model reconstruction, and volume measurement in different scan phases were performed with Mimics software. The results showed that the bladder varied from small bowl-like shape to irregular ellipsoid during urinary store. The increase in bladder volume was nonlinear under the specific conditions of water-drinking. The diameter change of the bladder in different directions was inconsistent during urinary store.
