Interventional magnetic resonance imaging, also interventional MRI or IMRI, is the use of magnetic resonance imaging (MRI) to do interventional radiology procedures.. Because of the lack of harmful effects on the patient and the operator, MR is well suited for "interventional radiology", where the images produced by an MRI scanner are used to guide a minimally-invasive procedure ...
Intraoperative magnetic resonance imaging (iMRI) is an operating room configuration that enables surgeons to image the patient via an MRI scanner while the patient is undergoing surgery, particularly brain surgery. iMRI reduces the risk of damaging critical parts of the brain and helps confirm that the surgery was successful or if additional resection is needed before the patient's head is ...
Functional MRI (fMRI) Blood-oxygen-level dependent imaging: BOLD: Changes in oxygen saturation-dependent magnetism of hemoglobin reflects tissue activity. [26] Localizing brain activity from performing an assigned task (e.g. talking, moving fingers) before surgery, also used in research of cognition. [27] Magnetic resonance angiography (MRA ...
A specialized growing subset of interventional MRI is intraoperative MRI, in which an MRI is used in surgery. Some specialized MRI systems allow imaging concurrent with the surgical procedure. More typically, the surgical procedure is temporarily interrupted so that MRI can assess the success of the procedure or guide subsequent surgical work ...

Image-guided surgery was originally developed for treatment of brain tumors using stereotactic surgery and radiosurgery that are guided by computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) via technologies such as the N-localizer [11] and Sturm-Pastyr localizer.

Volume rendering techniques have been developed to enable CT, MRI and ultrasound scanning software to produce 3D images for the physician. [24] Traditionally CT and MRI scans produced 2D static output on film. To produce 3D images, many scans are made and then combined by computers to produce a 3D model, which can then be manipulated by the ...
