초록

Background and Objectives: Multi-detector CT (MDCT) is becoming more commonly used as a diagnostic tool
for various cardiac diseases, and this modality can also incidentally detect a significant number of non-cardiac
findings during cardiac work-ups. The objectives of this study were to evaluate the incidence of non-cardiac
findings during cardiac MDCT and to compare them with chest CT. Subjects and Methods: We enrolled 1,007
consecutive subjects (mean age: 49±10 years, males: 63%) who underwent both cardiac and chest CT (64-slice
MDCT) as a part of a routine health check-up. The subjects were evaluated for the incidence of non-cardiac
findings and the therapeutic consequences according to the CT protocols during the mid-term follow-up (average
length of mid-term follow-up: 533±39 days). Results: Eight hundred sixty incidental non-cardiac findings were
identified in 627 patients (62%) with cardiac CT. Forty-three subjects (4%) had clinically significant lesions that
required additional diagnostic work-up or radiological follow-up, and these lesions were 23 cases of non-calcified
nodule, 2 cases of ground glass opacity, 6 cases of pneumonia, 1 case of active tuberculosis, 2 cases of focal bronchiolitis,
3 cases of arterial lesion, 1 case of liver cirrhosis and 5 cases of extra-pulmonary masses. Five subjects
(0.5%), including 2 cases (0.2%) of malignancy, had therapeutic consequences during their follow-up. Compared
with chest CT, 68% (40/59) of the significant intrathoracic lesions and 67% (4/6) of the intrathoracic lesions with
therapeutic consequences were documented by cardiac CT. Conclusion: In the present study, 4% of the asymptomatic
patients who underwent cardiac MDCT were found to have significant non-cardiac findings that
required further work-up. To avoid missing a number of clinically important findings, physicians who analyze
cardiac MDCT scans should carefully evaluate not only the heart, but all the other organs that are within the
scan range.
