How much patient movement is acceptable during scans? Is there any way of determining if there has been unacceptable patient movement at the time of the scan?
The only acceptable movements are: postural relaxation as the patient relaxes during the scan and the movement caused by breathing. Unacceptable patient movements include: gross movements of the torso of more than a couple of millimetres left or right across the FOV (a few pixels at 256 x N); rotation causing a similar shift in liver tissue at any point; or any perceivable shift along the bore of the MRI scanner. Shifts in the saline bag of greater than approximately 1.25 cm (half an inch) are also unacceptable. Unacceptable patient movement, including movement causing significant shift of the saline bag, will require the patient to be rescanned. It is possible to identify unacceptable patient movement at the time of scanning. You may choose to view the images directly after the scan, while the patient is still in the scanner. If this is performed and unacceptable movement is detected, a rescan can be performed immediately, rather than having to call the patient back. Detection of unac
