It allows intraoperative localization of tumor extent and identification of residual disease, hence maximizing tumor resection. Its utility has been widespread in high-income countries for the past 20 years, but in lower-middle-income countries (LMIC), it is still not widely available due to several reasons, including cost constraints. The use of intraoperative pMRI may be a cost-effective and efficient substitute for conventional MRI machines. The authors present a case where a pMRI device was used intraoperatively in an LMIC setting. Case Description: The authors performed a microscopic transsphenoidal resection of a sellar lesion with intraoperative imaging using the pMRI system on a 45-year-old man with a nonfunctioning pituitary macroadenoma. Without the need for an MRI suite or other MRI-compatible equipment, the scan was conducted within the confinements of a standard operating room. Low-field MRI showed some residual disease and postsurgical changes, comparable to postoperative high-field MRI. Conclusion: To the best of our knowledge, our report provides the first documented successful intraoperative transsphenoidal resection of a pituitary adenoma using an ultra-low-field pMRI device. The device can potentially enhance neurosurgical capacity in resource-constrained settings and improve patient outcomes in developing country.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/130d7e40-a393-4b54-b634-3a358f4f2791/featured/hero-1781560224066.png","publishDate":"2023-06-23T00:00:00.000Z","doi":"10.25259/SNI_124_2023","categories":["Unique Case Observations","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2023/06/12380/SNI-14-212.pdf"}
