Neuroinflammation plays a crucial role in HIV-infected subjects at risk of cerebral small vessel disease. As MR-Elastography (MRE) has shown the potential to link inflammation with brain stiffness reduction, we investigated the brain viscoelastic properties of the HIV-infected and HIV-uninfected individuals. The preliminary results with MRE are promising, complementing other imaging modalities such as diffusion MRI (DTI, NODDI) to investigate brain microstructure integrity in HIV infection.
