This info is included in the Health Page, in the one entitled "MRI Protocol for the Diagnosis and Follow-up of MS."
It is a long and technical document, so I wanted to highlight a section towards the end which describes the details which should be included in the radiology report. It states:
"The report should use common language and be descriptive including:
• Lesion number, location, size, shape, character and a qualitative assessment of brain atrophy.
• Comparison with previous studies for new, enlarging and/or enhancing lesions and atrophy.
• Interpretation and differential diagnosis."
In looking back on my numerous MRI reports, all of this data is not always included. I finally get my Nov 2008 results from my GP on Monday, and will be checking for this. If any of it is not included, I'm going to push the envelope a bit and request she follow up with the radiologist for what might be missing.
