Intraoperative imaging offers potential for utility in many clinical scenarios. Portable computed tomography (CT) offers a versatile potential alternative when immediate imaging may alter the surgical plan and magnetic resonance imaging is not practical.
The medical records from the University or New Mexico were reviewed for portable head CT scans done in the operating room since the scanner has been available. Operative reports and imaging studies were reviewed to determine changes in surgical decision after the CT scan.
The portable head CT scanner was used in 50 cases from May 2007 through March 2010. Average operative time overall was 121 minutes and for reservoir placement was 54 minutes. Procedures included reservoir placement (28%), tumor resection (24%), cerebrospinal fluid shunting (24%), vascular lesion resection (8%), trauma craniotomy (6%), abscess drainage (4%), stereotactic biopsy (4%), and open reduction internal fixation of facial fractures (2%). Findings on the CT scan lead to alterations in the surgical plan 16 times (32%).
In select cases, intraoperative portable head CT leads to changes in the surgical plan in 32% of cases. This potentially prevents a return to the operating room and offers a cost-effective alternative to fixed intraoperative imaging facilities.
术中成像在许多临床情况下都有应用潜力。当即时成像可能改变手术计划且磁共振成像不实际时，便携式计算机断层扫描（CT）提供了一种多功能的潜在替代方案。
自该扫描仪投入使用以来，对新墨西哥大学医学记录中在手术室进行的便携式头部 CT 扫描进行了回顾。对手术报告和影像学研究进行了回顾，以确定 CT 扫描后手术决策的变化。
2007 年 5 月至 2010 年 3 月，共使用了 50 例便携式头部 CT 扫描仪。总体手术时间平均为 121 分钟，储液器放置时间为 54 分钟。手术包括储液器放置（28%）、肿瘤切除（24%）、脑脊液分流（24%）、血管病变切除（8%）、创伤开颅术（6%）、脓肿引流（4%）、立体定向活检（4%）和面部骨折切开复位内固定（2%）。CT 扫描结果导致手术计划改变 16 次（32%）。
在某些情况下，术中使用便携式头部 CT 会导致 32%的病例手术计划发生变化。这可能避免了再次返回手术室，并提供了一种经济有效的固定术中成像设施替代方案。
