Imaging In Cns Infections

Imaging In Cns Infections Mr imaging is much more sensitive for detecting early changes of cns infections and depicting various imaging findings during each disease process, due to its high anatomy resolution, superb soft tissue differentiation, multiplanar acquisition, and versatile sequences of delineating different characters of pathologic processes of cns infections.

Imaging In Cns Infections Despite remarkable progress in prevention and treatment, infectious diseases affecting the central nervous system remain an important source of morbidity and mortality, particularly in less developed countries and in immunocompromised persons. bacterial, fungal, and parasitic pathogens are derived from living organisms and affect the brain, spinal cord, or meninges. infections due to these. Central nervous system (cns) infections—i.e., infections involving the brain (cerebrum and cerebellum), spinal cord, optic nerves, and their covering membranes—are medical emergencies that are associated with substantial morbidity, mortality, or long term sequelae that may have catastrophic implications for the quality of life of affected individuals. Imaging plays a central role in the early diagnosis of brain infections and in the detection of related complications, in patients presenting to the ed. while many organisms share non specific and overlapping manifestations, others have characteristic imaging findings that may allow a prompt confident diagnosis. Ct and mri are the choices of imaging modality in neuroinfections. neurosonogram plays a small but significant role in detecting intracranial infections in the early infantile period when fontanelle are open. [ 1] contrast mri is the ultimate imaging modality of choice in neuroinfections. the limitation of ct being usage of ionizing radiation.
