Abstract Objective To investigate the clinical application value of CS-MRCP by comparing the image quality of conventional 3D-MRCP and 3D-MRCP with compressed sensing (CS) technique. Methods A retrospective analysis was performed on 120 patients who received MR cholangiopancreatography in the First People’s Hospital of Huai’an from January 2022 to December 2022. All patients underwent 3D-RT-MRCP and CS-3D-RT-MRCP sequence scanning. Thepatients were divided into even breathing group and uneven breathing group according to respiratory rhythm, and the scanning time was recorded. The degree of respiratory motion artifact was scored, and the image of CNR and SNR were calculated according to the quality of the obtained image and the display of the pancreatic duct. The scanning time, image quality score, CNR and SNR of the two sequences were compared. Results The scanning time of CS-3D-RT-MRCP sequence was (79.32±23.64)s, lower than (240.32±41.78)s of 3D-RT-MRCP sequence, and the difference was statistically significant (P<0.05). According to the respiratory rhythm, 81 cases were divided into even breathing group and 39 cases were divided into the uneven breathing group. 3D-RT-MRCP sequence showed that the degree of artifact in the even breathing group was lower than that in the uneven breathing group, and the artifact degree of CS-3D-RT-MRCP sequence images in the uneven breathing group was lower than that in the 3D-RT-MRCP sequence, thus the difference was statistically significant (P<0.05), while the artifact degree of CS-3D-RT-MRCP sequence image between the two groups and the artifact degree of patients in the even breathing rhythm group had no statistically significant difference. The image quality scores, SNR and CNR scores of CS-3D-RT-MRCP were higher than those of 3D-RT-MRCP images, and the differences were statistically significant (P<0.05). The 3D-RT-MRCP sequence image scores, SNR and CNR scores in the uneven breathing group were lower than those in the even breathing group, and the difference was statistically significant (P<0.05). There was no significant difference in CS-3D-RT-MRCP image quality score, SNR orCNR scores between uneven breathing group and even breathing group (P>0.05). Conclusions The application of CS technique in 3D-MRCP examination can significantly shorten the scanning time, reduce the artifactsand improve the image quality.
