10 questions to ask your doctor after getting a CT scan
Most patients leave follow-up appointments having understood less than they needed — not because their doctor wasn't helpful, but because they didn't know the right questions to ask. These 10 questions are designed to help you understand your results, know what happens next, and leave the appointment with clarity instead of anxiety.
You've got your CT scan report. Maybe you've read it, maybe you haven't. Either way, you have a follow-up appointment coming up and limited time with your physician. The right questions make the difference between leaving with clarity and leaving with more confusion than you arrived with.
Here are the 10 most important questions — plus what to listen for in the answers.
This gets your physician to prioritize. CT reports can be dense and contain many incidental observations. You want to know which findings actually matter clinically and which are essentially background noise.
Establishes the timeline and urgency before everything else. If something needs to happen in the next 24–48 hours, you need to know that first.
Replace [specific finding] with the actual term from your report — "pulmonary nodule," "hypodense lesion," "ground glass opacity," or whatever is there. Physicians sometimes assume patients understand medical shorthand. You are entitled to a plain-English explanation.
Context matters enormously in radiology. A finding that has been stable for 5 years is far less concerning than one that appeared in the last 6 months. If your physician has access to prior imaging, they should compare.
Many CT findings require surveillance — a follow-up scan in 3, 6, or 12 months to confirm stability. Understanding why a specific interval was chosen helps you understand the level of concern.
Some CT findings are best evaluated by a specialist (pulmonologist for lung findings, gastroenterologist for abdominal findings, neurologist for brain or spine findings, etc.). If your primary care physician or ER physician reviewed your results, ask whether a specialist should be involved.
This is your safety net question. Even if your follow-up is scheduled for 6 months from now, you need to know which symptoms would move that timeline up — things that might indicate the finding is progressing or causing problems.
If you have a prior medical history (cancer, autoimmune disease, chronic infection, medications), ask whether the CT finding could be explained by it. Your physician has the clinical context; make sure they've connected the dots.
You have the legal right to your imaging data. DICOM files are the raw image data from your scan — far more informative than a printed CD image or a screenshot. Having your own copy lets you share with other physicians, get second opinions, and track changes over time.
Radiology findings often have implications beyond the immediate clinical question. An incidental kidney cyst found on a chest CT, a spine finding on an abdominal CT — these need to travel with your medical history. Ask your physician to flag anything worth carrying forward.
Bonus: how to prepare for your appointment
- Read the Impression section of your report before the appointment — the numbered summary at the end
- Write down the terms you don't understand and look them up before going in
- Bring a list of your questions — it's completely normal and your physician will respect it
- Consider uploading your scan to DICOM Reader before your appointment so you understand your own images and arrive with context
- Ask if you can record the explanation if you find you can't retain everything in the moment
