Noticeably, patients with more than four T1 hypointense lesions had EDSS scores≥4. The presence of T2/FLAIR hyperintense brain lesions correlated with EDSS (3.6±1.6 vs 2.3±1.7; p-value=0.01). EDSS was similar between those with and without positive AQP-4 (2.7±1.6 vs. 3.2±1.7; p-...
All of the 51 enhancing lesions were hyperintense on DWI (type I lesion). Of the 51 enhancing lesions, one was hypointense on the ADC map and hyperintense on the eADC map (type IA lesion; Figure 1), while the other 50 lesions were isointense to hyperintense on the ADC map and ...
The classification of lesions based on their hypointense or hyperintense appearance is hampered by the influence of field strength and pulse sequence parameters. An alternative approach (but not commonly used today, clinically) is to calculate tissue relaxation times, thus providing a quantitative ...

The aims of the present study were: (a) to assess for the first time the effect of interferon-尾-1a on T1 weighted MRI hypointense lesion volume; and (b) to evaluate the relation between changes on hypointense, hyperintense, and enhancing lesion volume before and during interferon-尾-1a ...
