Fig. 4. Ultrasonography images and SERA diagnostic results of a 58-year-old man with a FNA-proven benign nodule. The lesion was assessed as ACR TI-RADS category 3 nodule by a radiologist. Compared with the original PACS image (A), the picture taken with a mobile phone (B) was brighter and had lower resolution, but the diagnostic results of SERA were both benign (A, B, respectively). ACR TI-RADS: American College of Radiology Thyroid Imaging Reporting and Data System, PACS: picture archiving and communication system, SERA: Severance Artificial intelligence program
