Reports & Second Opinions
Repeat Scan or Re-Read: — How to Get a Second Opinion on Your Images
Before you book a new PET-CT scan for a second opinion, ask whether your existing images can simply be re-read by another specialist. In most cases, they can — and it costs far less than a new scan.

- The images can travel — Your DICOM image files can be sent securely to any specialist, anywhere, without you repeating the scan.
- The report is not the images — A second opinion on a PDF report alone gives the reviewer far less to work with than the actual image files.
- New scans are sometimes necessary — If enough time has passed or your condition has changed, the existing images may no longer answer the question.
- Ask your oncologist first — They can tell you which option applies and refer you to the right specialist for the re-read.

Yes, the same PET scan images can be re-read by a different radiologist or nuclear medicine specialist without repeating the scan. Your DICOM image files — not just the printed report — go to the second reader along with your clinical notes. A re-read costs a fraction of a new scan and is available at most centres.
PET-CT at CION starts from Rs 10,499 — among the lowest published prices in Hyderabad, with no hidden charges. Indicative price, as of September 2026.
How do you get a second read on your existing images?
Request your DICOM image files
Contact the imaging centre where the scan was done and ask for your DICOM files on a CD or via a secure digital link. The printed or PDF report alone is not enough — the second reader needs the raw image data.
Collect your original report and clinical notes
Gather the written report from the first read, your oncologist's referral letter, and any relevant clinical summary. A re-read without this context gives the second reader less to work with.
Ask your oncologist for a referral
Your oncologist can refer you to a nuclear medicine physician or diagnostic radiologist with experience in your cancer type. Some centres also accept direct requests for a second read.
Send images and clinical notes together
The images, original report, and clinical summary go together as one package. Many centres accept secure digital transfer; some still need a physical CD.
Share the second report with your treating team
The new read goes back to your oncologist, not to you alone. Two reports that say different things need a clinical discussion to resolve — not a decision made in isolation.
When is a re-read not enough — and when do you need a new scan?
A re-read works when the question is about interpretation: whether a finding is suspicious, whether it represents disease or something benign, or whether the staging assessment looks correct.
A new scan is needed when the images themselves are the problem — when they are too old to reflect your current situation, when the original scan was technically inadequate, or when your oncologist needs to see how the disease has changed since the first scan was done.
If you are unsure which applies, ask your oncologist to name the exact question they are trying to answer. That question determines whether existing images can answer it.

Re-read or new scan: which applies to your situation?
| Situation | Re-read of existing images | New scan needed |
|---|---|---|
| You want a different specialist's interpretation | Yes — same images, second reader | No |
| The report is unclear or uses unfamiliar language | Yes — another reader can clarify | Rarely |
| You want to check whether the staging is correct | Yes — staging is an interpretation decision | Only if the original scan was technically inadequate |
| Significant time has passed since the scan | Less useful — images no longer reflect current disease | Yes |
| Your symptoms or condition have changed since the scan | Less useful — existing images cannot show current state | Yes, to assess current status |
| The original scan was technically poor quality | Second reader faces the same limitations | Yes — a repeat with better technique |
What to collect before requesting a re-read
- DICOM image files — ask for these by name, not just the printed or PDF report
- The written report from the original read
- Your referral letter or a brief clinical summary from your oncologist
- The exact date the scan was done and the name of the imaging centre
- Any earlier scans you have, for comparison — note if they are on different CDs or platforms
- A clear written question for the second reader, ideally agreed with your oncologist beforehand

Common questions
Frequently asked questions
Can any radiologist re-read a PET scan, or does it need a specialist?
PET-CT images are best reviewed by a nuclear medicine physician or a radiologist with specific training in nuclear medicine. A general radiologist may not have the depth of experience to comment reliably on PET uptake patterns. Ask your oncologist to refer you to someone with experience in your specific cancer type — the interpretation depends on knowing what normal variation looks like for that disease.
How much cheaper is a re-read compared to a new scan?
A re-read is substantially less expensive than a repeat PET-CT. The cost of a professional second read is a small fraction of what a full scan — including the radiopharmaceutical, scanner time, and reporting — costs. The exact figure depends on the specialist and the centre. Ask the second reader's centre for their reporting or consultation fee before you arrange it, so there are no surprises.
How long does a re-read take?
Turnaround depends on the specialist and the centre, and no standard time can be quoted here. When you submit the images, ask the second reader's centre directly what to expect. If your clinical question is time-sensitive, your oncologist can flag the request accordingly. Plan for at least a few working days in most situations rather than assuming a same-day result.
What if the two reports disagree?
Disagreement between two reads is more common than most people expect, and it does not automatically mean one reader is wrong. Both reports should go to your treating oncologist together. They will consider both interpretations alongside your full clinical picture and, if needed, discuss the case with a multidisciplinary team or seek a further opinion. Do not try to resolve a disagreement between two reports on your own.
Can CION help arrange a second read on my images?
Your treating team at CION can help you work out whether a re-read or a new scan is the right step, and can advise on referral to an appropriate specialist. PET-CT scans at CION are coordinated with partner imaging centres. Raise the question at your next appointment, or contact the centre directly, to discuss what is appropriate for your specific situation.
