Overview
MRI is useful for the assessment of the anatomical locations and severity of the disease. The typical appearance of endometriosis includes a characteristic hyper intensity on T1-weighted images and a hypointensity on T2-weighted images.
MRI
- MRI is the best diagnostic tool to assess the locations of the endometrial lesions and to assess the severity of the disease.[1][2]
- The typical appearance of endometrial lesions is a characteristic hyper intensity on T1-weighted images and a hypointensity on T2-weighted images.[3]
- Powder burn hemorrhages: lesions appear hyperintense on T1 and hypointense on T2 Adhesions, fibrosis and distortion of normal anatomy such as posterior displacement of the uterus and angulation of bowel loops. Fluid collections uterosacral involvement irregular margins, asymmetry and nodularity and thickening medially if bilateral uterosacral involvement with additional involvement, torus uterinus involvement results in an arciform abnormality vaginal involvement loss of hypointense signal of the posterior vaginal wall on T2 thickening, nodules and/or masses also potentially seen pouch of Douglas partial to complete obliteration suspended or lateralised fluid collections rectovaginal septum nodules or masses that have passed through the lower border of the posterior lip of the cervix gastrointestinal tract Sensitivity may be increased with the use of water enema and endovaginal coils: rectal wall thickening anterior displacement of the rectum abnormal angulation loss of fat plane between uterus and bowel inflammatory response due to repeated hemorrhage can lead to adhesions, strictures and bowel obstructions urinary tract localised or diffuse bladder wall thickening signal intensity abnormality nodules or masses usually located at the level of the vesicouterine pouch chest catamenial pneumothorax haemothorax lung nodules malignant transformation solid enhancing components
