The purpose of this discussion forum is to to create a collaborative environment in which you can strengthen your use of medical terminology and critical thinking skills while constructively sharing ideas and opinions regarding a medical scenario.
MRI was performed through the brain, cervical spine, and upper thoracic region.
Scans were generated in the transaxial, sagittal, and coronal (frontal) planes.
Evaluation of the brain parenchyma demonstrates the presence of multiple areas of abnormal increased signal intensity scattered through the white matter of both cerebral hemispheres. These areas are periventricular in location . The pattern is most compatible with a demyelinative process. Scans through the cervical spine and spinal cord demonstrate no definite areas of abnormal increased or decreased signal within the cord. The discs are intact. Evaluation of the upper thoracic region demonstrates an appearance similar to that of the cervical region.
Note: The image to the left is an example and is not the MRI of this scenario.
1. Using the scenario above, answer the following questions:
A. What is an MRI? Briefly explain how it works.
B. What combining forms indicate the regions of the body imaged?
C. What is the brain parenchyma?
D. From the report, what is a likely diagnosis (Alzheimers, Parkinsons, Amyotrophic lateral sclerosis, and Multiple Sclerosis) ? Explain why.
Follow these guidelines when answering the questions:
