MRI颅表定位网在颅内小病灶定位中的应用

Application of MRI cranial surface locating device in localization of small intracranial space-occupying lesions

目的:探讨MRI颅表定位网在颅内小病灶术前定位中应用的可行性。方法:采用MRI颅表定位网定位技术,对30例颅内小占位病灶进行术前定位,然后通过手术验证精确度,并与徒手定位的方法进行比较。结果:30例应用MRI颅表定位网定位技术的患者经过术中检验,定位精确度明显超过用徒手定位的方法。结论:MRI颅表定位网可以明显提高颅内小病灶术前定位的准确性,且安全有效,无损伤,是用于颅内小的占位性病变术前定位的重要方法,值得推广。

Objective To explore the feasibility of applying MRI cranial surface locating device in localization of small intracranial space-occupying lesions before the surgeries. Methods Thirty patients with small intracranial space-occupying lesion were localized by MRI cranial surface locating device before the surgeries. The clinical accuracy was verified during the surgeries and the results were compared with cases without using the device. Results According to the verifications during the surgeries, 30 cases which used MRI cranial surface locating device showed much higher accuracy than that using the traditional method. Conclusions MRI cranial surface locating device can precisely delineate the surgical target area. The device is easy to operate and also can help to design the rational surgical approach with minimum injuries, significantly improve accuracy of locating small intracranial space-occupying lesions and it is safe, effective and worthy of widely used clinically.
