When a radiograph has high DQE, what combination of signal and noise is typically observed?

Explanation:
High DQE means the detector is efficient at converting incoming x-ray photons into a usable image signal while keeping noise low. When more of the incident photons contribute meaningfully to the image and random fluctuations (noise) are minimized, the resulting image has a strong signal with relatively little interference from noise. This improved signal-to-noise balance makes details easier to see and the image clearer for the same exposure. In short, high DQE translates to high signal with low noise, rather than low signal or high noise.
