Localization of Intracranial Lesions Using Superficial Stereotaxic Cranial Lesion Locator Based on Magnetic Resonance Images

摘要

Background. Detection of a deep-seated lesion located in the brain parenchyma and major neuroanatomical sites is a critical issue in neurosurgery. Some neurosurgical cranial navigation systems have been developed that are available; however, some preparation is necessary, including the installation of complex computer software programs and obtaining specific neuroradiological images. Objective. The purpose of this experimental study was to design and evaluate a superficial stereotaxic frameless lesion locator in order to localize mass lesions within the brain. Methods. A superficial stereotaxic frameless lesion locator system was designed using cardboard and the Cartesian coordinate system as a reference framework. This material was used in a model creating printed magnetic resonance images in the superficially marking of the lesion. This material easily located the lesion placement and superficially projected the lesion location. Results. The results of this study revealed that the superficial stereotaxic frameless lesion location procedure using a coordinate cardboard locator is a safe, fast, and simple procedure. This procedure provides an accurate means of locating the target lesion seated within the brain parenchyma. When compared with other models, we found that this device is reliable and has a high rate of superficial lesion detection. Conclusion. A superficial lesion locator may be used in clinical practice. This experimental study demonstrated the usability and reliability of the procedure. Additional detailed investigations are necessary to improve the procedure.
