Question

There are a variety of nervous system pathologies that present a challenge for producing quality images. For example, the movements associated with Parkinson’s can make it difficult to image a patient.

For this discussion use the PMI online library to research various nervous system pathologies.

1. In your first post, identify a pathology and provide a very brief synopsis of the disease, including signs/symptoms that may affect the quality of imaging.

Answer 1

Newrous System pathology: Multiple Sclerosis • It is predominantly a white matter diseas & a neurodegenerative disorder of the central hervous system that includes the brain, of Spinal cord & neuves. . It is an inflammatory 4 demyelinating diseas - Inflammation : body's own immune cells attack the newous system - Demyelination: myelin (protective covering of the newes) is destroyed leaving multiple areas of scout tissue or sclerosis. .
