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 isointense to hypointense on the eADC map (type IB lesion; Figure 2). Among ...
Lesion appearance on combined T1-weighted, T2-weighted, and immediate gadolinium-enhanced spoiled gradient-echo images was as follows: 102 lesions (29%) were hypointense on T1-weighted images, were hyperintense on T2-weighted images, and exhibited diffuse heterogeneous enhancement; 52 lesions (15%)...

While clinical-radiological correlations are limited in general, hypointense T1 lesions (also known as Black Holes (BH)) have shown some promising results. The definition of BHs is very heterogeneous and depends on subjective visual evaluation. We aimed to improve ...
CONCLUSION: The absence or presence of contrast uptake may indicate a different pathologic basis for hypointense MS lesions on T1-weighted MR images. These differences should be kept in mind when considering T1 lesion load as a surrogate marker of disability in MS....
OBJECTIVE Recently, a strong correlation between the increase in hypointense lesion load on T1 weighted spin echo images, and the increase in disability was reported. Although the effect of interferon-尾 has been demonstrated both in reducing exacerbation rate, frequency of enhancing lesions, and ...
