Which region is included as a subcortical structure in ASPECTS scoring?

• A. Caudate
• B. Insular cortex
• C. M1 cortex
• D. M6 cortex

Answer: (A)

ASPECTS scoring in acute stroke uses a 10-point CT framework to detect early ischemic changes in the MCA territory, dividing regions into subcortical and cortical areas. Subcortical structures include the caudate nucleus, the lentiform nucleus, and the internal capsule. The insular cortex, along with the six cortical regions labeled M1–M6, are considered cortical areas. Therefore, the region that is included as a subcortical structure is the caudate, while the insular cortex and the M1/M6 regions are cortical.
