Flashcards
Early Arterial Phase
Early Arterial Phase
Occurs about 20 seconds after contrast administration begins, highlighting the arterial tree with minimal pancreatic parenchyma enhancement.
Purpose of Arterial Phase
Purpose of Arterial Phase
Used to visualize the arterial tree and detect hypervascular tumors or metastases in the pancreas.
Study Notes
- Contrast enhanced imaging of the pancreas occurs in three phases.
- The early arterial phase takes place around 20 seconds after contrast administration begins.
- During this phase, contrast uptake is visible in the arterial tree.
- There is minimal enhancement of the pancreatic parenchyma during the early arterial phase.
- This phase is useful when CT angiography is needed.
- The arterial phase helps in identifying pancreatic hormone-producing tumors due to their hypervascular nature.
- Hypervascular metastatic deposits in the pancreas can also be detected in this phase.
