The benefits of reduced field-of-view (rFOV) imaging with the single-shot echoplanar diffusion sequence such as lower distortion and better discrimination of tumor from benign tissue have been demonstrated in several anatomies. In most of these published works, lower ADC was reported using rFOV compared to the standard full FOV (fFOV) method, irrespective of the technique by which rFOV was achieved. In this work we conducted controlled experiments in 3 phantoms to avoid some of the confounding factors present in vivo and investigated if there is a systemic underestimation of ADC in rFOV DWI compared to fFOV DWI.
