How to Read Your CT Scan Report: What Patients Need to Know

7 min readMarch 25, 2026Written by a Board-Certified Radiologist

CT scan reports describe findings in detail that can be alarming without context. Learn how to interpret the most common CT findings calmly and accurately.

What Is a CT Scan Report?

A CT (Computed Tomography) scan uses X-rays to create detailed cross-sectional images of the body. After a radiologist reviews these images, they produce a written report describing their findings.

CT scans are extremely detailed, which means the report can be long and contain many findings — some significant, some incidental, and some that are simply normal variations.

How to Read a CT Report

Start with the Impression. Skip to the last section of the report first. This is where the radiologist summarizes their most important findings. If the impression is reassuring, the detailed findings section is less likely to contain anything alarming.

Read the Findings in context. The findings section describes everything the radiologist sees, organ by organ. A finding that sounds alarming in isolation may be completely benign in context.

Look for the word "acute." As discussed in our previous article, "acute" means new or urgent. If the report says "no acute findings," that is reassuring.

Common CT Findings Explained

"Hypodense lesion" — An area that appears darker than surrounding tissue on CT. In the liver, a small hypodense lesion is often a simple cyst — very common and benign.

"Calcification" — Calcium deposits in tissue. These are extremely common and usually represent old, healed inflammation or injury. They are not the same as cancer.

"Diverticulosis" — Small pouches in the wall of the colon. Very common in adults over 50. Usually harmless unless inflamed (diverticulitis).

"Atherosclerotic calcification" — Calcium deposits in artery walls, indicating hardening of the arteries. Common with age.

"Mild hepatomegaly" — Slightly enlarged liver. Can have many causes and requires clinical correlation.
