Microvessels may Confound the “Swallow Tail Sign” in Normal Aged Midbrains: A Postmortem 7 T SW‐MRI Study
CONCLUSIONBoth iron deposits and microvessels contribute to the hyposignal surrounding nigrosome 1 in susceptibility weighted imaging of normal aged midbrains at ultrahigh ‐field strength. When assessing the substantia nigra for the presence or absence of the “swallow tail sign,” intrinsic vessels may be a sporadic confounder.
