DQE is an actual number represented in a percentage. Which percentage below would be considered the highest DQE?

Explanation:
Detective Quantum Efficiency (DQE) shows how effectively a radiographic detector turns incoming x-ray quanta into a usable image, and it’s expressed as a percentage. The higher the DQE, the more efficient the detector, meaning you can achieve the same image quality with less dose or get better image quality at the same dose. Among the given values, 80% is the largest, so it represents the highest DQE. The other options—70%, 50%, and 30%—are lower and thus indicate less efficient detectors.
