Brachial Plexus MRI Positioning Positioning for the brachial plexus exam is especially important. To ensure the nerves and forelimbs can be well assessed, both limbs should be positioned as symmetrical as possible, and pulled rostrally and well secured. Proper limb positioning will ensure that the peripheral brachial plexus nerves can be imaged closest to isocenter, compared slice-to-slice, and without excessive slice coverage. Typically dorsal recumbency is preferred, and any compatible coils…

Brain Herniation Brain Herniation Brain herniation is the protrusion of brain tissue through an opening due to compression. The cause of compression may be due to edema, swelling or dilation of tissues, mass effect from a tumor, congenital malformation, or hemorrhage. There are several types of brain herniation:

Cervical Spine MRI Scan Coverage and Planning Cervical Spine Anatomy page in development. Sagittal Plane On the axial and dorsal scout imaging, plan the slices parallel to the center of the spinal cord. On the sagittal scout image, center the FOV on C5. For each patient, the FOV should be re-sized to include the Cerebellum to include the T3 vertebral body. On the dorsal scout image, add enough slices to cover the entire vertebral body out to the transverse processes.

Cranial Nerve Pathology Cranial Nerves The cranial nerves in feline and canine patients are similar to those in humans; there are 12 pairs or nerves, many of which serve similar functions and have similar naming conventions as compared to humans. This page will not be an in depth discussion of cranial nerve anatomy or specific pathology, but will focus on concise and applicable information for identifying pathology and selecting and using appropriate imaging techniques.

Hemorrhage Hemorrhage Hemorrhage is the presence of blood outside of a vessel, and may have a number of different causes. Some of the most common causes of hemorrhage in the brain are neoplasia and trauma. Patient presentation and symptoms will vary depending on the location and size of the hemorrhage. Unlike ischemic disease, patient with brain hemorrhage may progress to worse symptoms and outcomes due to swelling or continued bleeding, leading to an increase in intracranial pressure. When…

Anonymous (anonymous@undisclosed.example.com) — 2026-05-26T17:16:54+00:00

Ischemia Ischemia Ischemia is reduced perfusion to an area of tissue due to an occlusion of a vessel. The occlusion of a vessel reduces or prevents downstream cells from getting fresh oxygenated blood resulting in a state of hypoxia. If severe enough, cell death and infarction can occur. Most occlusions are due to a thrombus, embolism, or thromboembolism.

Intervertebral Disc Disease Intervertebral Disc Disease (IVDD) Intervertebral disc disease results from degeneration of the intervertebral disc and is most common in dogs. IVDD can occur in any section of the spine and in any breed of dog, though there are breed and location predilections. IVDD has both external factors like trauma, and genetic factors. The primary genetic predilections are between Chondrodystrophic Breeds and Non-chondrodystrophic Breeds. Herniation may refer to any displacem…

Meningioma Meningioma Meningiomas are typically benign and slow growing tumors arising from the meninges. They are commonly well encapsulated, focal, round, and solid. Less commonly, meningiomas can be invasive, have plaque-like shapes, or varied internal composition. They can occur anywhere along the CNS, but are most common around the brain. Meningiomas have a few key identifying characteristics; some or all may be present:

Plexus Pathology Plexus Pathology Locating pathology in either the brachial or lumbar plexus can be difficult; the nerves are small, have tortuous routes, extend far into the limbs, and run parallel to veins and arteries. In the case of the brachial plexus, there is also respiratory motion and ventral location to consider. An imaging approach appropriate for these pathologies is described in the
