Abnormalities incidentally discovered in the Shanghai Changfeng study IFs could be observed on different images; here are some examples; the imaging features of the abnormalities are indicated with red arrows in each case. (A) Axial SWI image clearly depicts CMBs in the thalamus as hypointense areas; (B) Axial FLAIR image shows hyperintense areas in the deep white matter, representing WMH; (C) Axial T2-weighted image depicts crescent-shaped lesion that is isointense relative to the cerebrospinal fluid, findings that indicate chronic subdural hematoma; (D) Axial SWI image reveals venous malformation in the frontal lobe as hypointense atypically shaped areas; (E) Sagittal T1-weighted image demonstrates well-defined rounded foci that are isointense relative to gray matter in the sella turcica, representing pituitary adenoma; (F) Axial T2-weighted image shows meningioma as a hyperintense extra-axial mass that associated with the falx cerebri.
