Abstract:
Intraoperative MRI (iMRI) is a neurosurgical adjunct used to maximize the removal of glioma, the most common primary brain tumor. Increased extent of resection of gliomas has been shown to correlate with longer survival times. iMRI units are variable in design and magnet strength, which can affect patient selection and image quality. Multiple studies have shown that surgical resection of gliomas using iMRI results in increased extent of resection and survival time. Level II evidence supports the use of iMRI in the surgical treatment of glioma.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
