How is pectus excavatum diagnosed?
The diagnosis of pectus excavatum is made with a simple physical examination. Quite often, the defect does not become noticeable until the early teen years. A more detailed workup, including chest imaging by MRI or CT scan and cardiopulmonary (heart and lungs) exercise testing, accurately measures how serious the pectus is and its effect on cardiopulmonary (heart and lung) function. Echocardiogram and pulmonary function tests (PFT’s) may also be used to evaluate pectus excavatum.
