Application of intraoperative magnetic resonance imaging in large invasive XXXX surgery.

OBJECTIVE: To investigate the clinical application value of intraoperative magnetic resonance imaging (iMRI) in large invasive @entity977 surgery. METHODS: A total of 30 @entity1 with large @entity977 underwent microscopic @entity5 resection under the assistance of an iMRI system; 26 cases received surgery through the nasal-transsphenoidal approach, and the remaining four cases received surgery through the pterion approach. iMRI was performed one or two times depending on the need of the surgeon. If a @entity41 was found, further resection was conducted under iMRI guidance. RESULTS: iMRI revealed @entity41 in 12 cases, among which nine cases received further resection. Of these nine cases, iMRI rescanning confirmed complete resection in six cases, and subtotal resection in the remaining three. Overall, 24 cases of @entity5 were totally resected, and six cases were subtotally resected. The total resection rate of @entity5 increased from 60% to 80%. CONCLUSION: iMRI can effectively determine the resection extent of @entity977 . In addition, it provides an objective basis for real-time judgment of surgical outcome, subsequently improving surgical accuracy and safety, and increasing the total @entity5 resection rate.
