計算方法と公式
Start at 10; subtract 1 for each of C, L, IC, I, M1–M6 with early ischaemic change.
Score each region for hypodensity/effacement consistent with acute ischaemia; exclude chronic change when possible.
計算例(数値代入)
以下の数値は本ツールの入力欄に定義された例示値であり、本ページの数式でサーバー側で実際に計算したものです。計算過程を素早く確認できます。代入方法の例示のみで、臨床上の助言ではなく、実在する症例でもありません。
| Caudate (C) early change | No (keep point) |
|---|---|
| Lentiform (L) early change | No (keep point) |
| Internal capsule (IC) early change | No (keep point) |
| Insular ribbon (I) early change | No (keep point) |
| M1 (anterior MCA cortex) early change | No (keep point) |
| M2 (MCA cortex lateral to insular ribbon) early change | No (keep point) |
| M3 (posterior MCA cortex) early change | No (keep point) |
| M4 (anterior MCA superior) early change | No (keep point) |
| M5 (lateral MCA superior) early change | No (keep point) |
| M6 (posterior MCA superior) early change | No (keep point) |
→ASPECTS10/10
- Regions with early change:0
- Bands (contextual):Higher score — less early MCA change
| Caudate (C) early change | Yes (−1) |
|---|---|
| Lentiform (L) early change | Yes (−1) |
| Internal capsule (IC) early change | Yes (−1) |
| Insular ribbon (I) early change | Yes (−1) |
| M1 (anterior MCA cortex) early change | Yes (−1) |
| M2 (MCA cortex lateral to insular ribbon) early change | Yes (−1) |
| M3 (posterior MCA cortex) early change | Yes (−1) |
| M4 (anterior MCA superior) early change | Yes (−1) |
| M5 (lateral MCA superior) early change | Yes (−1) |
| M6 (posterior MCA superior) early change | Yes (−1) |
→ASPECTS0/10
- Regions with early change:10
- Bands (contextual):Extensive early MCA change
結果の判読と層別
Higher scores = less early injury; thresholds for reperfusion are pathway-specific and must include NIHSS, time and advanced imaging.
ガイドライン要点(独自整理)
- 10 MCA regions.
- Pair with NIHSS and vascular imaging.
- 次: local stroke code / reperfusion checklist.
以上は該当ガイドラインの要点を本サイトが独自に整理したものであり、原文の引用ではありません。
注意点と限界
- 非適応: posterior-circulation-only syndromes (use pc-ASPECTS variants if locally adopted), non-MCA territory decisions alone.
- 落とし穴: scoring chronic infarcts as acute early change.
- ASPECTS alone must not approve or deny thrombolysis/EVT.
