Summary
Human immunodeficiency virus (HIV) impacts the central nervous system (CNS), affecting cerebral blood flow and brain structure. Neuroimaging techniques like MRI and PET offer insights into HIV-related neurological changes and treatment monitoring.
Area of Science:
- Neuroscience
- Radiology
- Infectious Diseases
Background:
- Human immunodeficiency virus (HIV) infection is linked to significant central nervous system (CNS) alterations.
- These neurological changes can impact cerebral blood flow (CBF), brain metabolism, structure, and diffusion processes.
- Understanding these effects is crucial for managing HIV-associated neurocognitive disorders.
Purpose of the Study:
- To review experimental studies that utilize neuroimaging techniques to evaluate CNS changes in HIV.
- To highlight the utility of various imaging modalities in understanding HIV's neurological impact.
- To discuss the potential of neuroimaging in monitoring disease progression and treatment efficacy.
Main Methods:
- Review of experimental studies employing advanced neuroimaging techniques.
- Inclusion of techniques such as SPECT, PET, volumetric MRI, fMRI, MRS, DTI, and pMRI.
- Analysis of studies focusing on cerebral blood flow, metabolism, structure, and diffusion in HIV.
Main Results:
- Neuroimaging reveals diverse CNS changes associated with HIV.
- Each technique provides unique insights into HIV neuropathogenesis.
- Imaging can potentially track disease progression and response to antiretroviral therapy.
Conclusions:
- Neuroimaging is a valuable tool for studying HIV-related CNS alterations.
- Advanced imaging techniques offer a comprehensive view of HIV's neurological effects.
- These methods hold promise for personalized treatment strategies and patient monitoring.
