Motivation: Limitations of the FIGO classification of fibroid by MRI include interobserver variability, especially for large lesion, leading to distortion of the uterine landmarks.
Goal(s): We aim to evaluate the accuracy and reliability of FIGO type using organ-axial T2WI .
Approach: Organ- and body-axial T2WI were used to identify FIGO classification of fibroids. FIGO types assigned by each radiologist and operation outcome were compared. The association and correlation between FIGO types and cavity compression parameters were analysis.
Results: Organ-axial images showed excellent consistency (kappa=0.877, P=0.04) and accuracy (kappa=0.932, P=0.037) . Compression angle exhibited linear correlation with FIGO types with r of 0.68 (P<0.001) .
Impact: High resolution organ-axial T2 weighted MR could provide exceptional reliability and accuracy in identifying the FIGO classification for uterine fibroid and can be applied to assist in treatment planning and assessing response assessment.
