Imaging

CT and thermography compared

The two methods offered here work in very different ways. This page explains what each one measures, what it cannot tell you and how both differ from MRI.

Cross-sectional X-ray imaging

CT imaging

Computed tomography combines X-ray measurements taken from many angles into cross-sectional images of internal structures. A scan covers a specific body region and uses a protocol chosen for the question being asked.

CT involves ionizing radiation, so the body region and protocol should match a clinical need.

Skin-surface temperature

Thermography (DITI)

Digital infrared thermal imaging records relative temperature differences on the skin. A qualified professional considers those patterns together with your history, symptoms and other appropriate tests.

A temperature pattern alone cannot establish a diagnosis, and thermography does not replace mammography.

Side-by-side comparison

MRI is included for comparison only. It is not one of the services described on this website.

How CT, thermography and MRI differ
MethodWhat it showsHow it worksKeep in mind
CTCross-sectional images of internal structuresX-ray measurements from many angles, using ionizing radiationShould answer a defined clinical question. A normal scan does not rule out every condition.
Thermography / DITIRelative temperature patterns on the skin surfaceAn infrared camera records heat given off by the skinUsed alongside other clinical information. Does not diagnose a condition by itself or replace mammography.
MRI (for comparison)Images of internal structuresMagnetic fields and radio wavesA different method. The CT and thermography services described here are not MRI examinations.

“Full body” describes an area, not a method. If an option is described as full body, ask which method it uses and exactly which areas it includes.

Choosing a method

The right method depends on the question your clinician is trying to answer, your history and any earlier tests. When you call, have that recommendation ready and ask what the examination involves and whether the requested study is available here.
