Overall IQ | |
Grading | 1: Good |
2 Moderate | |
3: Poor | |
Vessel visualization | |
Grading | 1: clear visualization of all hepatic arteries including fine peripheral hepatic arteries at the subcapsular region without blurring |
2: clear visualization of hepatic arteries up to subsegmental level without blurring, but indisctinct fine peripheral hepatic arteries at the subcapsular region | |
3: blurriness of hepatic arteries but traceable up to subsegmental level | |
4: moderate blurring of hepatic arteries with pruning of subsegmental arteries | |
5: severe blurring of hepatic arteries with difficulty in tracing segmental hepatic arteries | |
Presence of (cardiorespiratory) artifacts | |
- Diaphragmatic motion d | Definition: Motion artifact width of right hemidiaphragm on sagittal image |
Grading | 0: none (< 0.1 mm) |
1: mild (0.1- 2 mm) | |
2: moderate (2.1–3.5 mm) | |
3:severe (> 3.5 mm) | |
Hepatic artery-to-parenchyma ratio | Definition: Ratio of intraarterial HU value 2 cm distally to the catheter tip (ROI fitted to two thirds of the vessel diameter) and maximal parenchymal enhancement |
Preferred dataset for TACE | CACTOrg vs. CACTMC_no bone |
Need for additional imaging | Yes/no |
