Interventional brain neurosurgery has become one of the main approaches for treating neurological and psychiatric disorders. A cutting-edge trend in neurosurgical interventions is the use of MRI for guiding puncture procedures. However, most puncture needles are made of metal, which can cause significant image artifacts during MRI. For a given puncture needle, the magnetic resonance artifact is considered to be influenced by MRI sequences, with the choice of MRI system also playing a significant role in the resulting image quality.This study employs a titanium-zirconium alloy puncture needle to systematically evaluate its MRI artifact characteristics using A manufacturer and B manufacturer MRI systems under gradient echo (GRE) and fast spin echo (FSE) sequences. Electromagnetic simulations were also performed to model the MRI environment, and the simulated B1 field distributions were compared with the measured artifact results for comprehensive analysis. The radial artifact caused by the puncture needle under 3.0T MRI was approximately 7–9 mm. Electromagnetic simulations showed the distrotion of B1 closely matched the measured artifact size.

摘要

Interventional brain neurosurgery has become one of the main approaches for treating neurological and psychiatric disorders. A cutting-edge trend in neurosurgical interventions is the use of MRI for guiding puncture procedures. However, most puncture needles are made of metal, which can cause significant image artifacts during MRI. For a given puncture needle, the magnetic resonance artifact is considered to be influenced by MRI sequences, with the choice of MRI system also playing a significant role in the resulting image quality.This study employs a titanium-zirconium alloy puncture needle to systematically evaluate its MRI artifact characteristics using A manufacturer and B manufacturer MRI systems under gradient echo (GRE) and fast spin echo (FSE) sequences. Electromagnetic simulations were also performed to model the MRI environment, and the simulated B1 field distributions were compared with the measured artifact results for comprehensive analysis. The radial artifact caused by the puncture needle under 3.0T MRI was approximately 7–9 mm. Electromagnetic simulations showed the distrotion of B1 closely matched the measured artifact size.
