Tests · Low-dose chest CT

The lung-cancer screening test.
Ten minutes, minimal dose.

A low-dose chest CT is a rapid CT scan of the lungs, optimised to find small nodules at a fraction of a standard CT's radiation dose. It is the recommended screening test for lung cancer in current and former heavy smokers, and a common add-on for anyone screening the chest.

What it finds, and what it does not

What it finds, and what it does not.

Lung nodules, including small ones a whole-body MRI would miss, and other structural findings in the chest.

A low-dose chest CT does not evaluate the heart, abdomen or pelvis, and a nodule it finds is not automatically cancer. Most small nodules are not; the report sets out a follow-up interval rather than a diagnosis.

Suitability

Who it suits, and who should not have it.

Suits: Current and former heavy smokers, and anyone who wants dedicated lung screening alongside a broader work-up.

Should not have it: People who are pregnant. Tell your coordinator if you are or may be pregnant so the protocol can be adjusted.

In context

How it differs from the related test.

A whole-body MRI covers five regions but is not sensitive to small lung nodules; a low-dose CT is the narrower, purpose-built test for exactly that.

Which tier includes it

Included from Essential.

Every Medione checkup programme includes a low-dose chest CT outright, starting in the Essential band. Its two whole-body MRI programmes are the exception, and carry no chest CT. Severance includes one from Premium upward. Neither KMI programme carries one, and Hanaro sells a low-dose lung CT as an add-on instead. See /pricing/, or Medione's B-5. Precision - Respiratory Checkup for a chest work-up on its own.

FAQ

Questions worth asking before you book.

Who should get a low-dose chest CT?
It is most strongly recommended for current and former heavy smokers, following published lung-cancer screening criteria; anyone can add it to a broader screening program.
Is the radiation dose safe?
The dose is a small fraction of a standard chest CT, low enough that annual screening is the recommended protocol for the highest-risk group.
What happens if a nodule is found?
Most small nodules are not cancer. The report states a size, and a recommended follow-up interval or further test. Your own doctor decides next steps with that report in hand.
