Answer to Question 1

radiopaque contrast

Rationale: A radiopaque contrast is a positive agent that has a high atomic number. Radiopaque contrast agents could be barium or iodinated contrast. The contrast will appear white on the radiograph.

Answer to Question 2

increased sensitivity

Rationale: A greater amount of oxygen in tissues increases their radiosensitivity. The Oxygen Enhancement Ratio is determined by comparing the dose required to cause effect with and without oxygen.
