Score | Description |
|---|---|
Arterial phase 1. Uninterpretable 2. Severely deficient but interpretable 3. Moderately deficient but interpretable 4. Mildly deficient but interpretable 5. Perfect reproduction of reference | Large and small arteries visible and crossing arteries are distinct 1. Unusable for diagnosis 2. Small vessels not discernible; larger vessels not sharply defined 3. Fair vessel delineation; useful for diagnosis 4. Good vessel definition; small vessels visible 5. Excellent visualization of proximal through small distal vessels |
Capillary phase 1. Uninterpretable 2. Severely deficient but interpretable 3. Moderately deficient but interpretable 4. Mildly deficient but interpretable 5. Perfect reproduction of reference | Capillary blush — assessment of contrast flow through capillary vessels 1. Unusable for diagnosis 2. Small vessels not discernible; larger vessels not sharply defined 3. Fair vessel delineation; useful for diagnosis 4. Good vessel definition; small vessels visible 5.
