Fig. 2From: Optimal injection rate of ultrasound contrast agent for evaluation of focal liver lesions using an automatic power injector: a pilot studyExample of the workstation interface. A red circular region of interest is placed on the lesion (focal nodular hyperplasia) and a blue region of interest is placed in adjacent liver parenchyma. Time-intensity curves of the lesion (red curve) after modelization and of adjacent liver parenchyma (blue curve) after modelization are displayed on the right side Back to article page
