The goal is to automatically detect really poor quality data (and then manually confirm the defects).
I found some studies about automatic quality control of MRI:
Image processing…

Depending on the size of the area being scanned and how many images
are taken, the whole procedure will take 15 to 90 minutes.

What is the difference between a regular and full body MRI?
I understand that normal MRIs use a "coil" which is wrapped around the body and the machine scans only the area where the coil is located and the area is only about 12-16 inches or so in width. So, for example, if the spine needs to be MRI'ed then…

Does a patient have to lie on their back (supine) for an MRI scan?
Could a patient be on their stomach or side during an MRI exam?
I have had CT scans while on my side and it was no problem. The MRI technician says it is impossible to perform an MRI unless the patient is flat on their back.

What would be the consequence if one does not drink a lot of water immediately after an MRI with contrast agent (intravenously injected)?
Since the most commonly used compounds for contrast enhancement are gadolinium-based, which is toxic, would drinking very little water over the e.g. 5 hours after the MRI procedure result in some long-lasting effect (from disposition of…

Is there commercially available MRI or CT that can be used for anthropometric rather than diagnostic purposes?
In research journals, there are often operationalisations of such terms as "muscle cross-sectional area", and "muscle volume", and "adipose tissue volume" by means of MRI or CT scanning. Hence, I understand that MRI or CT can be used to measure the…
