ASPECTS21 scoring on an NCCT of a 52-year-old woman 2.5 hours after the onset of a left hemiparesis. Ten defined regions of the MCA distribution are identified on a normal left cerebral hemisphere at ganglionic (A) and supraganglionic (B) levels: the caudate nucleus (C), the lentiform nucleus (L), the internal capsule (IC), the insular cortex (I), and M1, M2, M3, M4, M5, and M6. The outlined areas in the right hemisphere show hypoattenuation in 8 regions given an ASPECTS score of 2.
