In 2016, the Board of the Acta Radiologica Foundation decided that an international prize should be awarded annually for the best scientific manuscript for a nonNordic country, consisting of a diploma and SEK 40,000. After a formal voting procedure, the section editors of Acta Radiologica have decided that the Acta Radiologica International Prize 2020 should be awarded to Dr Kim See Hyung (Fig. 1) from Kyungpook National University Hospital, Radiology, Republic of Korea, for his article “Determination of Gleason score discrepancy for risk stratification in magnetic resonanceultrasound fusion prostate biopsy” (1). Dr Kim See Hyung was born in 1972 in the Republic of Korea and got his MD at The Korean Board of Radiology in 2004. He defended his PhD in 2012 at Chungbuk National University, Republic of Korea. Dr Kim See Hyung is currently working as a professor at Kyungpook National University Hospital, Radiology in the Republic of Korea. Dr Kim See Hyung has authored/co-authored 42 papers in peer-reviewed journals – four in Acta Radiologica. The aim of the study was to characterize the clinical and MRI features of clinically significant prostate cancer with the discrepant Gleason score in MRIultrasound fusion biopsy. A total of 400 consecutive patients with suspected cancer lesions who underwent MRI-ultrasound fusion biopsy and subsequent prostatectomy were included. In the comparison of biopsy Gleason score with pathology Gleason score, matched lesions were defined as a Gleason score and discrepant lesions were defined as an upgrade of the Gleason score. Descriptive statistics were used to define clinical characteristics, including age, prostate-specific antigen, prostate-specific antigen density, and maximal cancer core length. There were 130 lesions with discrepant Gleason score in 124 patients. There was no significant difference in the age, prostate-specific antigen, and prostate-specific antigen density between the two groups, except for the maximal cancer core length. The lesions were distributed with 88 in the peripheral and 42 in the transition zone; 33, 50, and 47 lesions were at the apex, mid-gland, and base, respectively. In comparison with matched lesions, discrepant lesions had significantly smaller cancer volume measured by multiparametric MRI. Knowledge of discrepant Gleason score in MRIultrasound fusion biopsy is important and a careful approach is needed to reduce this discrepancy. The official presentation of the Prize will take place during Nordic Congress of Radiology in Helsinki at the Acta Radiologica Award Session in May 2023. The manuscript will be presented orally during the Acta Radiologica Award Session. The Editorial Board congratulates Dr Kim See Hyung for winning the 2020 International Scientific Prize.
