[Abstract] Objective To assess the impact of intelligent quick magnetic resonance (IQMR) reconstruction technology on the image quality and quantitative parameters of diffusion-weighted imaging (DWI) in prostate cancer.Materials and Methods Axial T2-weighted imaging with fat-saturation (T2WI-FS) and field of view optimized and constrained undistorted single-shot DWI (FOCUS-DWI) sequences, along with clinical data, were retrospectively collected from 31 patients with prostate cancer. The FOCUS-DWI images were processed using the IQMR post-processing system to automatically generate IQMR-FOCUS-DWI images. Two radiologists independently evaluated two sets of images FOCUS-DWI and IQMR-FOCUS-DWI scoring them for noise level, geometric distortion, artifacts, and overall image quality. The signal-to-noise ratio (SNR) of prostate cancer lesions and the contrast-to-noise ratio (CNR) of prostate cancer lesions to the internal obturator muscles were measured and compared between the two image sets. Additionally, the apparent diffusion coefficient (ADC) values of prostate cancer lesions were measured and compared between the two sequences.Results Qualitative analysis showed that IQMR-FOCUS-DWI images received higher scores than FOCUS-DWI images in noise level, geometric distortion, and overall image quality (P ≤ 0.005). Although IQMR-FOCUS-DWI images also received higher artifact scores, the difference was not statistically significant (P = 0.313). Quantitative analysis revealed that SNR and CNR were significantly higher in IQMR-FOCUS-DWI images compared to FOCUS-DWI images (P < 0.001). There was no statistically significant difference in the lesion ADC values between the IQMR-FOCUS-DWI sequence and the FOCUS-DWI sequence (P = 0.061).Conclusions Compared to the FOCUS-DWI sequence, IQMR technology significantly improves the image quality of prostate DWI, resulting in higher SNR, CNR, and subjective image scores.
