How to Read a CT Report
A CT report has a structure similar to an X-ray report, but contains more detail because the exam is more thorough. Understanding its parts helps you follow your doctor's explanation.
Parts of the report
A CT report usually includes the reason for the exam, the technique (whether contrast was used and which protocol), findings organ by organ, and an impression. Findings can be long, so the impression is the most important summary.
Reports also often compare results with previous studies to assess change over time.
Terms you may encounter
'Lesion' means an abnormal area, but it does not automatically mean cancer. A 'nodule' is a small mass, while a 'mass' is usually larger. 'Calcification' means calcium deposits, which are often benign.
'Enhancement' indicates an area that takes up contrast, while 'hypodense' means an area that looks darker than the surrounding tissue.
Steps after reading
Do not draw conclusions on your own from the wording in the report. Write down anything you do not understand and ask the doctor who ordered the exam.
If the report recommends further testing or monitoring, follow the schedule. Routine monitoring is often the best approach for small findings that are not yet clear.
Key points
- The 'impression' section summarizes the key findings.
- Follow-up questions are best discussed with your doctor.
