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 Comprehensive.

Meridiko's Comprehensive tier includes one CT by region, and chest is one of the options. This is that scan. It is not included at the Essential tier. See /pricing/, or KMI's dedicated Lung precision program 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.
