[Mini-invasive interventions under magnetic resonance guidance in the clarifying diagnosis of small pelvic tumors].

Objective: To perfect and estimate the possibilities of using a mini-invasive diagnostic procedure under magnetic resonance (MR) guidance in the complex anatomic situations in cases of pathological small pelvic changes of unknown origin.

Material And Methods: Ten small pelvic interventions were made under MR guidance. The indications for bone biopsy under MR guidance were poor visualization of bone changes or their absence during radiography, including computed tomography.
