The pancreas is difficult to image because of its central location deep in the abdomen, often with overlapping artifact in parallel MRI reconstruction through the mid abdomen and drop off of signal. In this new concept for improved SNR and parallel MRI in pancreas MRI, a surface array is pushed/indented into the abdomen, bringing smaller array elements closer to the pancreas. Compared to the benchmark array, the Indenting Array demonstrated >2x SNR and 40% improved R=3 A-P parallel MRI with g-factor = 1 within the pancreas. This new “indenting” array design could have a significant impact on pancreas diagnostic MRI.
