The entirety of the acquired data is in the image you see.
You can turn the processing off and look at the images without it if you are worried.
You also don’t diagnose off one image. You use several in each plane, and more than one image weighting. The software is unaware of the other planes and images when processing.
You don’t need long playing with it to be very confident that it’s utterly transformed MR imaging.
An example: decent resolution cervical spine Sag T2 imaging used to take a few minutes (2 or 2:30?), it’s now 40 ish seconds. It’s made scans faster, and better looking.
