Best QA Parameter

Answer this...

If it were possible to measure only one parameter as part of an MR QA programme, which would you measure? Why?

The signal-to-noise ratio (SNR). It is sensitive to many faults which may occur in the MR system. This also means that whilst you may be able to detect a fault, it is a fairly non-specific indicator as to the source of the problem.
