There is a very large overlap between patients with normal chests and patients with pectus excavatum regarding Haller indices—normal patients can have technically abnormal Haller index without pectus, and vice versa.
Depending on the phase of respiration, the Haller index can change—some patients have abnormal indices at end expiration but normal indices at end inspiration despite clinical pectus excavatum.

clinicalThe depression index (greater than 0.2) accounts for variable chest shapes (barrel-shaped versus elliptical) and should be abnormal in pectus excavatum regardless of chest configuration.↗

clinicalThe earlier you get a CT and the higher the dose, the greater your long-term risk of developing malignancy; pediatric tissues divide more rapidly and have more time to develop DNA breaks.↗

clinicalA standard CT dose for pectus can deliver about 7 millisieverts of radiation, equivalent to about 2 years of background radiation in one scan.↗
