Evaluating the diagnostic accuracy of magnetic resonance angiography versus digital subtraction angiography for spinal dural arteriovenous fistulas: a systematic review and meta-analysis
{{output}}
Spinal dural arteriovenous fistulas (SDAVFs) are underrecognized, and delayed diagnosis can result in irreversible neurological deficits. Magnetic resonance angiography (MRA) provides noninvasive, high-resolution vascular imaging of SDAVFs. Digital subtraction... ...
