No, they are not. The detail of information you get from the MRI machine is tremendous. Though you can peek into the human body without a surgical procedure, from the patients perspective there are some disturbing facts:
1.) Its not the most comfortable place. Sticking your body in a barely fitting tunnel with an odd mask for 15-20 minutes without moving is itself challenging. Once in, your face is just about 2-3 cm away from the top of the tunnel. Afraid of closed spaces ? This is not the place to be. Miners might feel at home. Why couldn't they make this tunnel any bigger ?
2.) Alone. The 20 minutes might appear lonely for the miner too. Not sure why there isn't a mechanism to communicate between the caved-in fellow and the operator outside - a status update would always do good.
3.) Noises - This rather complicated modern machine grumbles like a bad boy each time it works. Grumbles for the machine turn out to be noise for the patient. Again, can't this ear-drum breaking buzz be avoided? The operator might suggest sleep as an option. Sure, if your entire life was spent in the engine room.
4.) Exit path - No procedure is in place for the caved-in fellow to exit in case of an emergency - say when you feel real frustrated and you just want to get out. A red button with an arrow would be nice.
Though the results from machine are of great help, we appear to have a long way to go in terms of the MRI technology. A small wearable device which does the job in under minute should be perfect? Yeah. Lucky grand-son.
