3D Volume Rendering of Pelvic Floor Anatomy Based on MRI Scans - Fan Ka Siu

Pdf Summary

This study aimed to evaluate the feasibility of using magnetic resonance imaging (MRI) scans to create three-dimensional (3D) models of the pelvis, focusing on fibroids and lower urinary tract symptoms (LUTS). The researchers used MRI scans of three patients with fibroids and mixed urinary incontinence to render 3D models of the bladder, uterus, and fibroids. They used image processing applications 3D Slicer and OsiriX to view and process the image sequences.<br /><br />The models created were of sufficient resolution to allow for measurements of the spatial relationships between the bladder, uterus, and fibroids. Measurements of fibroid volumes ranged from 5336 to 418012 mm3, and distances between the fibroids and bladder ranged from 0.10 to 83.60 mm. Statistical analysis showed no significant differences in measurements between the two image processing applications.<br /><br />The researchers concluded that image processing and 3D volume rendering is a feasible technique for studying pelvic anatomy in cases of uterine fibroids. It provides detailed anatomical dimensions and data on spatial relationships that were previously unobtainable from 2D MRI images. They also suggested that a 3D pelvic model could be valuable for preoperative surgical planning and clinical education. Further studies could evaluate the clinical role of this imaging modality.<br /><br />Uterine fibroids can affect urinary tract function and cause or worsen LUTS. Bladder compression by fibroids can lead to frequency, urgency, incomplete bladder emptying, and even obstruction. The development of 3D models from MRI scans could provide valuable information for understanding the impact of fibroids on pelvic anatomy and may aid in the management of fibroids and LUTS.
