Hvad er forskellen på en MR-scanning og en CT-scanning?

CT-scanning er baseret på røntgenstråling, mens MR-scanning benytter magnetfelter og radiobølger til at danne billeder af kroppen. MR-scanneren har den fordel, at den kan danne billeder i flere planer (vandret, lodret og skråt), hvorimod CT-scanning primært kun optager billeder på tværs (aksialplan).

Noncontrast CT is often normal in early cases of uncomplicated meningitis. 5 Later, the meninges may show contrast enhancement, suggesting inflammation. However, meningeal enhancement alone is not specific for meningitis ( Fig. 40-1 ).

How do you detect N meningitidis in real time?

Species-specific real-time PCR assays PCR detection of N. meningitidis, H. influenzae, and S. pneumoniae can be achieved by amplification of several potential gene targets ( 8, 35, 53, 60 ). The following assays have been developed and validated to be used on DNA extracted from clinical specimens (typically, blood and CSF) and bacterial isolates.

What is the clinical presentation of meningitis?

Clinical Presentation. The classic clinical features of meningitis include headache, neck stiffness, pyrexia, vomiting, and photophobia, followed by mental status changes. The definitive diagnosis is made by culture from blood or cerebrospinal fluid (CSF).
