T2WI SI ratio defined as (mean T2 SI at the solid portion of the tumor−mean T2 SI at the normal gluteus maximus muscle)/(mean T2 SI at the normal gluteus maximus muscle).
CI, confidence interval; MPMUT malignant pure mesenchymal uterine tumor; MRI, magnetic resonance image; SI, signal intensity; ULCD, uterine leiomyoma with cystic degeneration; WI, weighted image.
