It’s ‘only’ converting each pixel into 4, so the starting point is not going to change a lot. Also keep in mind that interpolating has been part of image reconstructions for 20+ years. MR suffers from slow acquisition times so we cheat and image resolution is rarely symmetrical in pixel dimensions when you compare x, y and z directions.
Previously we just made pixels square (made up data) then doubled the pixel count (more made up data). It was that dumb.
I’ve tried acquiring an image and up scaling it 2x. Then acquiring the same image at double the resolution and not upscaling.
It’s hard to compare as the longer acquisition is often hampered by patient movement.
When I set up a scan with the AI I’d estimate it as adding about about 30% signal. I make up a scan that will look good. Then turn the AI on, then shorten the scan or increase the resolution such that it’s 30% ish down on signal, then I press go.
We are seeing things we didn’t previously, particularly with cartilage injuries.
The same way we do for everything. We scan in multiple planes and image weighting’s (t1, t2fs, etc). Ax, sag cor. We do other angles for various things too. Eg for knees we do dedicated views for the patella cartilage and ACL.
