[Solid tumors of internal female reproductive organs: comparison of the diagnostic efficiency of ultrasound study and magnetic resonance tomography].
Comparison of the diagnostic importance of traditional US and low-field MRI (0,23 T) in the characterization of solid tumors of internal reproductive system at 55 patients is performed by calculation of operational characteristics of tests and use of characteristic curves (ROC-analysis). Advantage MRI in distinguishing between of benign and malignant tumors (accuracy of 82% against 71% at ultrasonic) is established. Advantage is based on use, besides morphological criteria of a tumor, the characteristic of its MR-signal in T2-weight imaging. Advantage MRI in determination of the organ of origin of pelvic mass appeared insignificant.
