Final answer:
An improperly tuned receiver coil typically results in a decreased Signal-to-Noise Ratio (SNR), leading to lower quality diagnostic images.
Step-by-step explanation:
If a receiver coil is improperly tuned (transmit gain outside of range), the most likely result would be a decrease in Signal-to-Noise Ratio (SNR). This means that the quality of the image would be compromised because the background noise would be relatively high compared to the actual signal that represents the area of interest in the image. This scenario doesn't typically lead to a dramatically reduced matrix size, a patient burn, or a zipper artifact, but rather to reduced quality of the diagnostic image due to less distinctive signaling from the area being scanned.
