To explore the diagnostic and therapeutic values of stereotactic guidance of intraoperative high-field magnetic resonance imaging (iMRI) for multiple intracranial lesions.
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).
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.
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.
探讨术中高场磁共振成像（iMRI）立体定向引导对颅内多发病变的诊断及治疗价值。
回顾性分析2011年6月至2013年5月间18例接受高场iMRI立体定向引导的颅内多发病变患者。手术包括立体定向引导下活检（n = 6）、脑脓肿立体定向穿刺引流（n = 4）、混合性实性和囊性颅咽管瘤立体定向穿刺及腔内32P照射（n = 3）和立体定向血肿清除术（n = 5）。
6例高场iMRI立体定向引导病例中，目标病变被精确预定，病理标本经临床随访结果证实。12例多发囊性病变和多发颅内血肿病例中，血肿及液体抽吸效果满意。临床治疗疗程明显缩短，术后并发症发生率较低。
iMRI可精确引导立体定向手术。对确诊颅内多发病变及缩短其治疗疗程具有重要临床意义。
