摘要
目的探讨术中磁共振（iMRI）影像导航应用于穿刺活检术的临床初步经验、优势与不足。方法在0．15TPoleStarN一20iMRI实时影像引导下，对6例颅内占位性质不明患者进行穿刺活检术。结果6例均获得组织病理学诊断，活检阳性率为100％；1例颅内多发占位患者术后并发左基底节活检区域局限性血肿。结论iMRI影像导航能及时纠正术中脑移位，即只有当iMRI确定穿刺针已位于病灶内才进行活检，从而有利于提高活检阳性率，减少术后并发症。
Objective To study the preliminary clinical experience, advantage and disadvantage of the brain biopsy procedure guided by low- field intraoperative magnetic resonance imaging （iMRI）. Methods Between August 2006 and February 2009, 6 consecutive brain biopsy procedures were performed using the mobile 0. 15 - tesla PoleStar N - 20 iMRI system in order to identify the pathological diagnosis of the intracranial lesions in these patients. Results All biopsy samples comprised pathological tissue, leading to a diagnostic yield of 100%. A tiny hematoma was detected at the region of biopsy of the left basal ganglion on postoperative CT scans in only one patient with intracranial multi - lesions. Conclusions iMRI - basedneuronavigation is feasible when using the mobile 0. 15 - tesla PoleStar N - 20 iMRI system for brain biopsy procedures. The most obvious advantage of using the system for brain biopsies is offering the opportunity of immediate verification of the location of needle tip, and this method produces a high histological yield and low complication rate.
