Probe for MRI imaging and spectroscopy particularly in the cervical region
摘要
An insertable intracavity probe for use in magnetic resonance imaging of an area of interest in a relatively inaccessible region of the body particularly the cervix is disclosed. The probe has an inflatable balloon structure with an internal pickup coil carried at the distal end of a shaft for rectal insertion of the coil and an inflatable anti-migration cuff to hold the probe in position and prevent outward migration thereof during a procedure. The balloon structure has an outer balloon shaped to facilitate insertion and accommodation of the coil to areas of the anatomy adjacent the cervix. Internally, the balloon structure has an inflatable balloon which can be used to adjust the shape of the coil to accommodate uniquely shaped anatomical areas.
