A brain MRI can help doctors look for conditions such as bleeding, swelling, problems with the way the brain developed, tumors, infections, inflammation, damage from an injury or a stroke, or problems with the blood vessels. The MRI also can help doctors look for causes of headaches or seizures. It can show if a shunt is working. Fetal MRI is commonly used to investigate underlying etiology for ventriculomegaly and morphologic brain abnormalities that are incompletely assessed with US. The brain evolves throughout gestation, making evaluation challenging to those unaware of the normal appearance of the anatomy at a specific gestational age [ 6 ]. Full integration of MRI and O.R. tables from various manufacturers offers hospitals maximum flexibility and workflow efficiency in cranial procedures. The Brainlab registration matrix with integrated MR markers is designed for use with a 3-pin skull clamp and therefore does not compromise standard patient positioning. A brain MRI (magnetic resonance imaging) scan, also called a head MRI, is a painless procedure that produces very clear images of the structures inside of your head — mainly, your brain.

If a scan is ordered to evaluate a headache disorder, MRI with contrast is preferred as it is a more sensitive test than CT and does not involve any radiation. However, as it is so sensitive, there are often abnormal findings unrelated to the headache that may lead to further testing. The most common abnormalities are small spots in the brain. Magnetic resonance imaging (MRI)-only radiotherapy treatment planning is attractive since MRI provides superior soft tissue contrast without ionizing radiation compared with computed tomography (CT). However, it requires the generation of pseudo CT from MRI images for patient setup and dose calculat. Ten healthy volunteers (mean age 29 +/- 7) were studied in supine and upright (sitting) postures. A Cine phase-contrast MRI technique was used to image the pulsatile blood flow to the brain, the venous outflow through the internal jugular, epidural, and vertebral veins, and the bi-directional CSF flow between the cranium and the spinal canal.

FUNDAMENTALS OF MR SPECTROSCOPY. MR spectroscopy provides a measure of brain chemistry. The most common nuclei that are used are 1 H (proton), 23 Na (sodium), 31 P (phosphorus). Proton spectroscopy is easier to perform and provides much higher signal-to-noise than either sodium or phosphorus. Proton MRS can be performed within 10-15 minutes and. The StealthStation™ S8 surgical navigation system has an intuitive interface, improved patient registration software, and advanced visualization to navigate neurosurgery procedures.

MRI is a noninvasive way for your doctor to examine your organs, tissues and skeletal system. It produces high-resolution images of the inside of the body that help diagnose a variety of problems. MRI of the brain and spinal cord. MRI is the most frequently used imaging test of the brain and spinal cord. It's often performed to help diagnose:. MR Spectroscopy - Single Neuro Protocol. The radiologist will plan the spect voxels. Typically they will want one on whatever lesion they are looking at, and one in normal healthy white matter. Voxel sizes: maximum 20 x 20 x 20, but you can go as small as 10 x 10 x 10. Make every effort possible to avoid placing any part of the voxelss inside .... The purpose of this study is to test whether an additional magnetic resonance image (MRI) sequence can improve the ability to distinguish radiation damage from tumor recurrence in participants with brain metastasis who have previously been treated with stereotactic radiosurgery (SRS). MRI allows the evaluation of the spinal cord. The cord may be directly damaged by a traumatic event or by impingement because of an associated injury, such as a herniated disk (Figures 4 and 5). 18 MRI can identify the level of cord injury and the associated soft tissue injuries. Because of this, it can assist in operative planning.
