Chapter 13, Problem 6QFS

Which medical imaging technique is most dangerous to use repeatedly, and why?

In which direction would an MRI scanner move to produce sequential images of the body in the frontal plane, and in which direction would an MRI scanner move to produce sequential images of the body in the sagittal plane?

What are two major disadvantages of MRI scans? release of radiation and poor quality images high cost and the need for shielding from the magnetic signals can only view metabolically active tissues and inadequate availability of equipment release of radiation and the need for a patient to be confined to metal tube for up to 30 minutes
