"FDG-PET/CT often (~75%) reveals regions of hypometabolism associated with the location of the DVA, especially in older patients 14,16."

"DVAs are very common as an incidental finding, with an estimated prevalence of 3-9% on contrast-enhanced MRI brain scans 13. Prevalence increases after the age of 1 year 13, passing from 1.5% in newborns to 9.6% in adults 21. Lesions are usually solitary (75%) 2. There are no sex differences 8."
"If there is an associated cavernous malformation, then susceptibility weighted sequences will also be most sensitive to this component 4. Additionally, in ~10% of cases, high T2/FLAIR signal can be seen in the surrounding white matter; the aetiology is not clear but may be due to gliosis, oedema or leukoaraiosis 12."
"developmental venous anomalies can be subtle on many MRI sequences; T1 C+ (Gd) and SWI are most sensitive"
