A short quality control acquisition was developed to detect hardware issues and receiver coil positioning errors in whole-body MRI (WB-MRI). Individual coil element images were reconstructed to investigate potential broken elements and coil positioning was assessed by comparison with images acquired using the integral body coil.
This approach was implemented in a group of healthy volunteers and patients with myeloma and successfully identified a previously undetected broken coil element. The expected signal difference between coil array and integral body coil images was defined and deviation from this expected profile was used to distinguish images acquired with deliberately imperfect coil set-ups.
