Acquisition value of signal to noise ratio (SNR), contrast to noise ratio (CNR) and apparent diffusion coefficient (ADC) on cross-sectional MRI (b = 1000s/mm2). a SNR and CNR measurement on readout segmentation of long variable echo-trains diffusion-weight imaging (RESOLVE DWI) image. ROI 1, the signal intensity (SI) of the lesion (SI lesion); ROI 2, SI of background noise (SI background); ROI 3, SI of the myosphere of the uterus (SI myosphere). b ADC value measurement of lesion on ADC maps of RESOLVE DWI. ROI 1, the ADC value of the lesion. The mean SNR, CNR and ADC values are 517, 348 and 635.1 × 10−6 mm2/s, respectively. c SNR and CNR measurement on single-shot echo-planar imaging diffusion-weighted imaging (SS-EPI DWI) image. ROI 1, the signal intensity (SI) of the lesion (SI lesion); ROI 2, SI of background noise (SI background); ROI 3, SI of the myosphere of the uterus (SI myosphere). d ADC value measurement of lesion on ADC maps of SS-EPI DWI. ROI 1, the ADC value of the lesion. The mean SNR, CNR and ADC values are 97.5, 73.7 and 605 × 10− 6 mm2/s, respectively. e Box plot shows significant differences were found in CNR values between the RESOLVE DWI and DWI group (P < 0.05). f The SNR values of the RESOLVE DWI group was significantly higher than that of the DWI group (P < 0.05)
