Reading Your Report
How Long Does a — PET-CT Report Take?
The wait for a PET-CT result is one of the hardest parts of the process. The scan does not generate a report automatically — a specialist has to review every image and write it up before your oncologist receives anything.
Medically reviewed by Dr. C. Raghavendra Reddy, Medical Oncologist, MBBS (Gold Medal) · DNB · DM (Medical Oncology, Gold Medal) · Last reviewed September 2026
- Not an automatic result — A nuclear medicine physician reviews every image before a report is written.
- A working-days wait — The report travels from the imaging centre to your oncologist — ask when to expect it at check-in.
- Urgent reads exist — If your oncologist needs the result faster, they can request a prioritised turnaround.
- The disc is not the report — Getting a CD of your images at the end of the session is not the same as receiving the written report.

PET-CT results are not instant. The images are reviewed by a nuclear medicine specialist who writes a formal report, which your oncologist then receives and discusses with you. The wait after your scan is usually measured in working days, not hours. Ask your imaging centre when the report is expected when you check in.
What do the terms in a PET-CT report mean?
- Nuclear medicine physician
- The doctor who reads and interprets your PET-CT scan. They are trained in imaging and write the formal report that your oncologist receives. The report is not produced by a machine or technician.
- SUV (Standardised Uptake Value)
- A number that measures how much radioactive tracer a particular area absorbed. It appears throughout PET-CT reports. Your oncologist interprets what it means in the context of your specific cancer and treatment history — the number alone is not a verdict.
- Preliminary read
- An informal or verbal interpretation given before the full written report is finalised. It is not the same as the signed document your oncologist uses to make decisions, and it may not cover every finding.
- Final report
- The written, reviewed, and signed document that is the authoritative interpretation of your scan. This is what your oncologist discusses with you at your appointment.
- DICOM images
- The raw scan files stored on the disc or CD you may receive after your session. These are the underlying images from which the report is written — having them early does not mean the written report will arrive sooner.
What should I do while waiting for my PET-CT report?
- Ask the imaging centre at check-in when the report will be sent to your oncologist.
- Note your appointment date — the result is discussed there, not delivered to you directly.
- Keep your scan disc or CD safe if one was given to you at the end of the session.
- Write down questions you want to ask your oncologist when you see them.
- Tell your treating team if your symptoms or condition change while you are waiting.
- Avoid interpreting specific terms from a preliminary read using internet searches.

Routine report versus urgent read: what is the difference?
| Routine report | Urgent or expedited read | |
|---|---|---|
| What it is | Full written, signed report from the nuclear medicine physician | A verbal or informal read given before the complete written report is ready |
| Who requests it | Your oncologist at the time of booking | Your oncologist, with the referral marked urgent |
| Typical purpose | Staging, restaging, or treatment response assessment | Pre-surgical planning or a time-sensitive clinical decision |
| Limitations | Not available same day at most centres | May not address every finding in the detail of a full report |
Why does a PET-CT report take so long to come back?
What actually happens between the scan and the report?
The scan produces thousands of images. A nuclear medicine physician works through each one, correlates it with the CT images, and checks areas of increased tracer uptake against your clinical history and any previous scans. That review cannot be rushed without compromising the accuracy your oncologist will base decisions on.
Can the report be done faster if it is needed urgently?
Yes. Most imaging centres can prioritise a report when the referring doctor marks the request urgent. This is a clinical decision made by your oncologist, not something you can request directly at the imaging centre. If the wait is causing you significant anxiety, tell your oncology team — they can request a faster turnaround where it is clinically appropriate.
I received the report before my appointment. Should I read it?
You can, but read it knowing it is written for doctors. Terms like 'avid', 'uptake', and 'SUV' have technical meanings that need your full clinical picture to interpret correctly. A word that sounds alarming in isolation may not be alarming in context. Prepare questions to bring to your appointment rather than drawing conclusions on your own.
Why does the report compare my scan to an older one?
A scan in isolation shows what is present. A scan compared with a previous one shows whether things have changed — whether areas of concern are new, stable, growing, or smaller. For someone already in treatment, change over time is often the more important question. If no prior scan is available for comparison, the radiologist will note this in the report.
The report and what my oncologist said seem different. Why?
The report describes what the specialist observed in the images. Your oncologist interprets that within your full clinical picture — your cancer type, treatment history, symptoms, and blood results. What sounds like a difference is usually the added layer of clinical context, not a contradiction. Your oncologist decides what the findings mean for your care.
Can I get a second opinion on the report?
Yes, and a responsible oncologist will not be offended by it. Take your scan disc and the written report to another nuclear medicine specialist or cancer centre. If the second reading differs, ask your oncologist to discuss both interpretations with you and explain which one they are working from and why.
A whole-body PET-CT at CION is Rs 10,499 — among the lowest published prices in Hyderabad — with a free Rs 950 oncologist consultation to talk through your report. Indicative price, as of September 2026.

Common questions
Frequently asked questions
When exactly will my PET-CT report be ready?
Your imaging centre is the only source of an accurate answer for your specific scan. Ask at check-in when the report is expected to be sent to your oncologist, and ask for a contact number in case you have not heard within that timeframe. Most centres can give you an expected date when you arrive for the scan.
Does a longer wait mean something is wrong with my result?
No. The wait is a fixed part of the process, not a signal about what the scan found. Every PET-CT goes through the same steps: image processing, specialist review, report writing, and delivery to your oncologist. A longer wait at a busy centre reflects workload, not anything about your findings. If you have waited noticeably longer than the centre indicated, call and ask for an update.
Will my oncologist call me with the result, or do I wait for my appointment?
In most cases, the result is discussed at your appointment. Your oncologist needs to interpret the report alongside your full clinical picture, and a phone call rarely allows for that properly. If your situation is urgent, your team will contact you. If your appointment is approaching and you have not heard that the report has arrived, call the clinic to confirm.
Can I take a CD of the scan images immediately after the scan?
Most imaging centres provide a disc with the raw scan images at the end of the session or on request. The disc contains the images but not the written report — that is a separate document produced after the nuclear medicine physician has reviewed everything. Having the disc early does not mean the report will arrive sooner.
The report uses words I cannot understand. What should I do?
Keep the report safely until your oncologist appointment and bring it with you. Write down any words or phrases that concerned you so you can ask about them directly. PET-CT reports are written in clinical language intended for doctors, not patients. Do not rely on internet searches to interpret what specific terms mean for your situation — the same word can carry very different weight depending on your clinical context.
My friend's PET-CT result came back the same day. Why is mine taking longer?
Different imaging centres have different turnaround times depending on their workload, staffing, and whether a nuclear medicine physician is reading on site or remotely. Your friend may also have had an urgent referral marked on their request. Neither pace is a signal about the result — it reflects the centre's capacity at that time, nothing else.
