This work presents a study measuring and characterizing the brain ultrashort-T2* component in patients suffering from MS. Our results show that the measured T2* relaxation time of the ultrashort-T2* component is significantly lower in almost all white matter ROIs measured. Fitted signal curves for the fractional component suggest the fractional component fits well in certain patients but not as well in others suggesting a more robust fitting model may be necessary for using this UTE relaxometry technique in patients with MS.
