The diagnostic yield of computerised tomography in human immunodeficiency virus (HIV) positive psychiatric patients at a tertiary hospital in the Western Cape
Background. HIV infection increases the risk for mental illness. Neuroimaging is an important part of the diagnostic workup in HIV+ psychiatric patients; CT is the primary neuroimaging modality available in resource limited settings. Despite advances in neuroimaging no clear guidelines exist for …
