Methods: Thirty consecutive patients who underwent abdominal MRI examinations because of pancreatic cystic lesions under observation between June 2024 and July 2024 were enrolled. We qualitatively and quantitatively evaluated the image qualities of SshTSE2mm and SshTSE5mm with and without DLR-SR. Results: The SNRs ofthe pancreas, spleen, paraspinal muscle, peripancreatic fat, and pancreatic cystic lesions of SshTSE2mm with and without DLR-SR did not decrease in compared to that ofSshTSE5mm with and without DLRSR. There were no significant differences in contrast-to-noise ratios(CNRs)ofthe pancreas-to-cystic lesions and fat between 4 types of images. SshTSE2mm with DLR-SR had the highest image quality related to pancreas edge sharpness, perceived coarseness pancreatic duct clarity, noise, artifacts, overall image quality, and diagnostic confidence of cystic lesions, followed by SshTSE2mm without DLR-SR and SshTSE5mm with and without DLRSR (P \u003C0.0001).  \nConclusions: SshTSE2mm with DLR-SR images had better quality than the other images and did not have decreased SNRs and CNRs. The thin-slice SshTSE with DLR-SR maybe feasible and clinically useful for the evaluation of patients with pancreatic cystic lesions.  \nKeywords: deep learning reconstruction, magnetic resonance imaging, pancreatic cystic lesion, single-shot turbo spin echo, thin-slice  \n1Department of Radiology, Hamamatsu University School of Medicine, Hamamatsu, Shizuoka, Japan  \n2Philips Japan, Tokyo, Japan  \n3Department of Radiological Technology, Faculty of Medical Science, Kyoto College of Medical Science, Nantan, Kyoto, Japan  \n4Department of Radiology, Hamamatsu University Hospital, Hamamatsu, Shizuoka, Japan  \n5Radiation Oncology, Hamamatsu University School of Medicine, Hamamatsu, Shizuoka, Japan  \n6Startup Support and URA Office, Institute of Photonics Medicine, Hamamatsu University School of Medicine, Hamamatsu, Shizuoka, Japan  \n*Corresponding author: Department of Radiology, Hamamatsu University School of Medicine, 1-20-1, Handayama, Chuo-ku, Hamamatsu, Shizuoka 431-3192, Japan.
