Common Mistakes Made on MRI in MS
MR images are the most important paraclinical tool in diagnosis and follow up of multiple sclerosis. There are clear cut parameters and criteria to make diagnosis, but often mistakes are made when based on imaging characteristics alone. It is very important to recognize the lesions on MRI and to be able to provide an adecuate differential diagnosis in order to make a correct diagnosis and therefore provide the adecuate treatment.
Objectives:
The purposes of this poster are:
To show the most common mistakes made on MRI interpretation in MS patients
To review the morphology of MS lesions on MRI and to allow a correct differential diagnosis based on imaging characteristics.
Methods:
This presentation reviews the imaging characteristics and the diffential diagnosis on MRI of T2 hyperintense (periventricular , subcortical and yuxtacortical lesions), black holes, dirty white matter, active lesions, pseudotumoral lesions, basal ganglia lesions, posterior fossa lesions, and lesions of the corpus callosum and the spinal cord.
Results:
This presentation reviews the imaging characteristics and the diffential diagnosis on MRI of T2 hyperintense (periventricular , subcortical and yuxtacortical lesions), black holes, dirty white matter, active lesions, pseudotumoral lesions, basal ganglia lesions, posterior fossa lesions, and lesions of the corpus callosum and the spinal cord.
Conclusions:
It is very important to recognize and comprehend the morphology of the tipical MS lesions on mri and to be able to tell them appart from similar lesions caused by other diseases, in order to establish a correct diagnostic and allow therefor the adecuate therapeutic approach.
