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.
