[Values of stereotactic guidance of intraoperative high-field magnetic resonance imaging for multiple intracranial lesions].

OBJECTIVE
To explore the diagnostic and therapeutic values of stereotactic guidance of intraoperative high-field magnetic resonance imaging (iMRI) for multiple intracranial lesions.


METHODS
We retrospectively assessed 18 patients with multiple intracranial lesions undergoing stereotactic guidance of high-field iMRI between June 2011 and May 2013. The procedures included biopsy of stereotactic guidance (n = 6), stereotactic aspiration and drainage for brain abscess (n = 4), stereotactic aspiration and intracavitary irradiation with (32)P for mixed solid and cystic craniopharyngiomas (n = 3) and stereotactic hematoma evacuation (n = 5).


RESULTS
For 6 cases with high-field iMRI stereotactic guidance, the target lesions were precisely predetermined and pathological specimens confirmed by clinical follow-up results. For 12 cases with multiple cystic lesions and multiple intracranial hematoma, aspiration of hematoma and liquids was satisfactory. And the course of clinical treatment was significantly shortened. And there was a lower incidence of postoperative complications.


CONCLUSION
iMRI may guide precisely stereotactic surgery. And it has important clinical significance for confirming the diagnosis of multiple intracranial lesions and shortening their treatment courses.
