Our goal is to compare liver lesion detection with T2 weighted images at 3T MRI and at 1.5T. A total of 56 solid liver lesions were detected at 1.5T and 3T. Three radiologist scored lesion detectability on a 0 to 2 scale: 0=definitely absent; 1 = probably present; and 2=definitely present. The contrast to noise ratio (CNR) of lesion to liver was calculated and compared at 3T and 1.5T. There was no statistical difference in lesion detection at the two different field strengths (p = 0.15). There was no statistical significant difference in CNR at the two different field strengths( p = 0.07).
