Urgent PET-CT
Urgent PET-CT: — When It Cannot Wait
A PET-CT scan can be arranged urgently when a clinical emergency makes waiting dangerous. Not every new symptom qualifies — urgency is a clinical judgement made by your treating team. Knowing which situations cannot wait gets you the right help at the right speed.

- Cord compression cannot wait — New weakness, numbness or loss of bladder or bowel control in a cancer patient needs immediate assessment — hours matter, not days.
- Not every symptom is an emergency — Urgency is a clinical judgement. The treating team assesses whether a situation qualifies before the urgent request is made.
- The pathway is direct — Your oncologist contacts the imaging partner directly. Urgent requests go outside the standard booking queue.
- Preparation still applies — Even urgent scans require fasting and a blood sugar check. Your team will confirm what to do before you leave home.

PET-CT can be arranged urgently when a clinical emergency — cord compression, airway involvement or rapid new neurological symptoms — makes waiting for a routine slot dangerous. Your oncologist requests it directly through the imaging partner and the scan is prioritised within hours. Not every new symptom qualifies; the treating team assesses urgency before the request is made.
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.
Does this situation need an urgent scan or can it wait?
| Can wait for routine booking | Needs urgent or same-day scan | |
|---|---|---|
| Clinical picture | Stable, no new neurological symptoms, next review already scheduled | New weakness, numbness, loss of bladder or bowel control, or breathing difficulty |
| Speed of change | Gradual or unchanged over days to weeks | Rapid change over hours to a couple of days |
| Risk of delay | Low — imaging will not change immediate management | High — delay could worsen an irreversible complication |
| Who initiates | Oncologist at your next scheduled appointment | Oncologist, after immediate clinical assessment of your symptoms |
| Timeline | Standard booking — days to weeks ahead | Same day to within 24 hours in genuine emergencies |
What should I tell the team when I call?
- When the symptom started and how fast it is worsening
- Any new weakness or numbness, and which part of the body
- Whether you have lost control of your bladder or bowel, or cannot pass urine
- Any new shortness of breath that has worsened over hours
- New back or neck pain that is severe and different from your usual pattern
- What you have eaten and when — needed to plan scan preparation

How does the urgent PET-CT pathway actually work?
When your oncologist decides a scan cannot wait, they contact the imaging partner centre directly. CION coordinates PET-CT through partner imaging centres, so urgent requests go outside the standard booking queue.
You will still need standard preparation even for an urgent scan — typically fasting for several hours and a blood sugar check on arrival. Your team will confirm what is needed before you leave home, because these steps matter for image quality.
Once the scan is complete, the report is turned around quickly. Your oncologist will explain what was found and what happens next, usually the same day.
Did you know?
Spinal cord compression from cancer is a neurological emergency. NCCN guidance states that imaging and intervention should begin within hours, because the window for preserving walking and bladder control narrows the longer compression continues unreported.
Reporting new weakness or loss of bladder control the moment it appears is what keeps that window open.

What should I expect from the urgent scan process?
Can a PET-CT really be arranged the same day?
In a genuine clinical emergency, yes. The imaging partner prioritises urgent requests that your oncologist has flagged directly. Same-day availability depends on scanner capacity on that day, and your team will tell you when to arrive. For the most severe presentations — suspected cord compression or airway threat — same-day imaging is the clinical standard, not an exceptional favour.
I have already eaten. Does that cancel the scan?
Tell your team before you leave home. PET-CT requires a fast of several hours and a blood sugar check before the tracer is injected. If you have eaten recently, your team will advise whether to come in now for assessment and delay the scan by a few hours, or whether same-day imaging is still possible. Do not assume the scan cannot happen — ask, and let the team decide.
What if my oncologist is not immediately available?
Call the CION centre you normally attend and ask for whoever is available from the oncology team. If you have symptoms suggesting cord compression — sudden weakness, numbness spreading from the neck or mid-back downwards, or loss of bladder or bowel control — go directly to the nearest emergency department while someone else contacts your team. These symptoms need immediate assessment regardless of scan availability.
Will the scan be accurate if it is done urgently?
Yes, if standard preparation is completed. Urgency of the request does not affect image quality — what matters is whether preparation steps were followed. Your team will confirm what you need to do before arriving, so a scan done quickly also gives useful information. If preparation cannot be completed in time, your oncologist will decide whether scanning now is still preferable to waiting.
Will I be admitted to hospital after the scan?
Possibly, depending on what the scan shows. If it finds cord compression, airway involvement or another urgent finding, your oncologist will usually want to begin treatment the same day, which may involve admission. Either way, you will not leave without an explanation of what was found and what the next step is.
CION does PET-CT in Hyderabad from Rs 10,499 — among the lowest published prices in the city — including an oncologist-reviewed report and a free Rs 950 consultation. Indicative price, as of September 2026.

Common questions
Frequently asked questions
My back pain is getting worse. When does that become urgent?
Back pain that is new, severe, and worsening quickly in a cancer patient deserves a same-day call rather than wait-and-see. The specific concern is cord compression, which typically begins with pain and progresses to weakness and loss of bladder or bowel control. If any numbness or weakness has appeared alongside the pain, call immediately. If it is pain alone but worsening faster than your usual pattern, call today rather than waiting for your next appointment.
Can a family member call to request an urgent scan?
A family member can call the CION centre to describe what they are seeing and ask for guidance. The decision to arrange an urgent scan belongs to the treating oncologist. Describe the symptoms clearly — when they started, how fast they are changing, and whether there is any new weakness or loss of bladder control — and ask to speak to whoever is available from the oncology team.
Does an urgent PET-CT cost more than a routine scan?
Indicative costs at partner imaging centres may differ from routine bookings and vary by centre. Your team will give you an indication before the scan is arranged. If cost is a concern, say so when you call — there may be options depending on your circumstances and how the scan is coordinated through CION.
What if the urgent scan shows nothing serious?
A scan that comes back without an emergency finding is reassuring, not wasted. The purpose is to rule out the things that cannot be safely missed — cord compression, airway involvement or rapid new disease. A clear result changes management in the same way a serious finding would: it tells your team what to continue and whether a different investigation is needed. Calling when something felt wrong was the right decision regardless of the result.
Is it safe to travel to the scan centre when I feel very unwell?
If you have new weakness, loss of bladder or bowel control, or severe difficulty breathing, go to the nearest emergency department rather than directly to the scan centre. For less acute symptoms, your team will advise on how to travel. Do not drive yourself if you have any neurological symptoms — weakness, numbness or dizziness — as these affect your ability to control a vehicle safely.
Why might an MRI be ordered instead of a PET-CT in an emergency?
MRI shows the spinal cord and surrounding structures in much greater detail than PET-CT, so it is often preferred when cord compression is suspected — it shows precisely where and how much the cord is being compressed. PET-CT is more useful when the question is about disease extent throughout the body, or metabolic activity in a suspected new area. Your oncologist will specify which scan best answers the clinical question.
