THE ROLE OF MRI IN PINEOBLASTOMA
Pineoblastoma is one of several different types of tumors that arise in the area of the pineal gland, requiring different therapies. The exact diagnosis is critical for choosing the correct therapy. Pineal tumors typically present with hydrocephalus, a buildup of fluid pressure within the brain.
When it comes to identifying this particular disease, there are a number of tests that can be carried out but the most efficient and most approved method is the use of magnetic resonance imaging (MRI) of the brain. It will show the location, the size and the shape of the tumor.
In the last 20 years, magnetic resonance imaging has proved to be the most informative imaging procedure for determining the anatomical localization of the mass, its relationship to adjacent vascular structures, and its spread by either direct invasion or subarachnoid dissemination.
Both CT scans and MRIs however lack specificity as to the histological nature of the tumor. It may however be popular for being highly accurate in determining the presence of a pineal region mass. New in the diagnostic field is magnetic resonance spectroscopy that has the role of evaluating pineal region tumors. It is currently relatively unknown but indeed promising. When it comes to matters of determining the nature and position of the tumor, the use of MRI to do this is clearly the best there is.
