MRI features associated with infectious intracranial aneurysms in infectious endocarditis


  • Infectious intracranial aneurysms (IIAs) are a complicating factor in infectious endocarditis (IE), and in this study magnetic resonance imaging (MRI) features such as susceptibility-weighted imaging (SWI) lesions and contrast enhancement are associated with IIAs.

Why this matters

  • Digital subtraction angiography (DSA) is the gold-standard for detection of IIAs, but MRI may be used as a less invasive option for screening for IIAs in IE.
