Why Guidelines are Important? Inter observer variability in assessing MRI signs of Endometriosis between reader following ESUR guidelines versus reader using prior domain knowledge
Oral Presentation at the European Congress of Radiology, Vienna, 2019
To assess the interobserver variability in identifying the MRI signs of endometriosis as described by European society of urogenital radiology.
Methods and Materials
This retrospective study included 77 randomly selected cases of endometriosis diagnosed on MRI. The cases were pulled from PACS, anonymized and assigned to two radiologists with 16 years and 11 years of experience in body imaging. The radiologists identified the presence or absence of following signs in each case: Retroflexion of uterus, torus
The interobserver variability ranged from ‘fair to good’ (Fleiss bounds, 0.41-0.75) in 9 labels (retroflexion, ovaries adherent to
We identified the MRI signs of endometriosis having high inter-observer variability. There is scope for improvement in the
