Charles Daniel Johnson is an American radiologist.

Johnson graduated from the College of Idaho with a degree in zoology. He subsequently studied medicine at Mayo Medical School, where he later completed medical residencies in internal medicine and diagnostic radiology. Johnson pursued a master's degree in diagnostic radiology from the University of Minnesota, followed by a fellowship and research training at Duke University. Johnson holds a second master's degree in medical management from Carnegie Mellon University. He is a professor of radiology and consultant to the Mayo Clinic Alix School of Medicine Department of Radiology.[1] In February 2014, Johnson became editor-in-chief of the journal Abdominal Imaging, succeeding Morton Meyers.[2] During Johnson's tenure as chief editor, the journal was renamed Abdominal Radiology in January 2016.[3]

Johnson has studied the effectiveness of virtual colonoscopy (colon cancer screening using CT scans) as compared to colonoscopy.[4] He said virtual colonoscopy finds 90% of large, precancerous polyps but is less successful with smaller ones.[5]
