A high-resolution computed tomography (HRCT) scan is an important tool to evaluate IPF. Several abnormalities can be observed using this method: ground-glass opacities, consolidation, reticulation, and honeycombing. The extent of fibrosis may also be measured by evaluating the combination of reticulation and honeycombing.

CT head (sometimes termed CT brain), refers to a computed tomography examination of the brain and surrounding structures. It can be performed as a single non-contrast study or the combination of a non-contrast and post-contrast (delayed) study. This allows the identification of abnormal contrast enhancement (e.g. tumours) and allows enhancement to be differentiated from intrinsic hyperdensity (e.g. blood). Dynamic contrast-enhanced studies can also be performed to assess specific vascular structures (see CT venogram and CTA circle of Willis) as well as assess how blood passes through the brain parenchyma (see CT perfusion).

A stress test, sometimes called a treadmill test or exercise test, helps your doctor find out how well your heart handles its workload. As your body works harder during the test, it requires more fuel and your heart has to pump more blood. The test can show if there’s a lack of blood supply through the arteries that go to the heart. You’re hooked up to equipment to monitor your heart. You walk slowly in place on the treadmill. It tilts so you feel like you’re going up a small hill. It changes speeds to make you walk faster after certain time interval. You can stop the test at any time if you need to.
