Medicare claims show overuse of chest CT scans at many hospitals nationwide, but not at Mass General.

Repeat CT scans not an issue at Mass General

21/Jun/2011

Long after questions were first raised about the overuse of powerful CT scans, hundreds of hospitals across the country needlessly exposed patients to radiation by scanning their chests twice on the same day, according to federal records and interviews with researchers.

Massachusetts General Hospital, however, had a 0 percent double-scanning rate, according to the data, with only 5 out of 4,973 patients receiving repeat scans.
