Haller found that patients with a Haller index greater than 3.25 were candidates for operation
guideline ·
Pectus Excavatum
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.
clinical ·
Pectus Carinatum
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.
clinical ·
Pectus Carinatum
The 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.

Statement
Haller found that patients with a Haller index greater than 3.25 were ones he operated on, but this was an observational retrospective study, not a rigorous scientific or prospective study.
Open
Quotation
I don't think it was very scientific. I think it was more of an observational thing he kind of looked at the number of the patients that he had performed in his surgery on and kind of came up with this number.

Open
Statement
The correction index (greater than 10%) shows no overlap between normal and abnormal patients, unlike the Haller index.
Open
Statement
The 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.

Children tolerate MRI very well; video goggle technology allows them to watch movies during the procedure, relieving anxiety.

Open
Statement
A standard CT dose for pectus can deliver about 7 millisieverts of radiation, equivalent to about 2 years of background radiation in one scan.
Open
Statement
There is data suggesting an increased risk of malignancy long term from even one CT, and the younger you are, that risk increases over your lifetime.

I think I'm a little bit claustrophobic. I find it hard being inside an MRI machine, but I have actually done an MRI with the goggles on. It's actually great.
