Acquire images in the appropriate plane – i.e., along the observation’s longest axis. If CEUS is performed for follow up of a previously detected observation, replicate the prior imaging plane using anatomic landmarks (e.g., portal and hepatic veins, gallbladder, falciform ligament) for orientation.
Measure the observation’s outer-to-outer edge dimension along its longest axis, using precontrast B-mode images if possible. If the margins are not clear on precontrast B-mode images, choose the CEUS image on which the margins are most clearly defined, avoiding the peak of arterial phase enhancement if possible. To evaluate size change between exams, select images on each exam acquired in the same plane and temporal phase.
