South Gujarat's first digital PET/CT

See it sooner. See it clearly.

A PET/CT is a scan that shows how the cells inside your body are behaving — not just what they look like. Prismaa runs Surat's only high-resolution digital PET/CT — sharper images, half the scan time, and a lower radiation dose. At the same price as a conventional scan.

So what is a PET/CT scan?

An X-ray or a CT scan is like a photograph of a city: you can see the buildings and the roads. A PET scan is like the same city photographed at night — now you can see which buildings still have their lights on. Cancer cells are the ones burning the most energy, so they light up brightest.

Understanding your scan

Why your doctor asked for a PET/CT

There are usually one of four reasons. Knowing which one applies to you makes the report much easier to understand when it arrives.

To find out if it is cancer at all

A lump on a CT scan may be a tumour, or scar tissue, or an old infection. PET shows whether it is metabolically active — and often spares people an unnecessary biopsy or operation.

To see how far it has spread

Treatment for cancer confined to one organ is completely different from treatment for cancer that has travelled. One whole-body scan answers that in a single pass, instead of six separate tests.

To check if treatment is working

A tumour can shrink and still be alive, or stay the same size and already be dead. PET shows which — usually months before size alone would tell you, so a failing regimen can be changed early.

To check for recurrence

After treatment ends, PET/CT can distinguish harmless scar tissue from disease that has come back, and can find recurrence while it is still small enough to treat aggressively.

What happens on the day

Your scan, from arrival to report

Around two and a half hours in the centre in total — most of it spent resting. The scan itself is the shortest part.

  1. Step 115 min

    Check in and get ready

    You come in having fasted for about six hours — water is fine and we want you to drink it. We check your blood sugar with a finger-prick, confirm your history and answer your questions.

    Bring a relative. They can stay with you until the injection.

  2. Step 22 min

    A small injection

    A tiny amount of a tracer — usually a sugar molecule carrying a safe, short-lived radioactive tag — goes into a vein in your arm. It is a single needle prick. You will not feel anything from the tracer itself: no warmth, no taste, no reaction.

    The dose is small, and it clears from your body within hours.

  3. Step 345 – 60 min

    Rest quietly while it works

    You rest in a quiet room while the tracer travels through your bloodstream and collects in the cells that are working hardest. Staying still and relaxed matters here — moving muscles absorb tracer too, and that can blur the picture.

    You can lie down. Most people doze off.

  4. Step 4≈ 15 min

    The scan itself

    You lie on a padded table that moves slowly through a wide, short ring. It is open at both ends — nothing closes over your face. There is no noise beyond a soft hum, and no pain at all. On a conventional scanner this part takes 25–30 minutes; our digital scanner does it in about fifteen.

    You can talk to the technologist at any moment. They can see and hear you throughout.

  5. Step 5Same day

    Go home

    You eat normally straight afterwards and go home. We ask you to drink plenty of water to flush the tracer out, and to keep a little distance from pregnant women and young children for the rest of the day — a precaution, not a danger.

  6. Step 6Usually within 24 hours

    Your report

    A fellowship-trained onco-radiologist reads your scan and issues a structured report written in the response criteria your oncologist uses. If you would like the findings explained face to face, we will sit down with you and your family and go through the images.

    Ask us. Nobody should leave holding a report they cannot read.

The technology difference

The same price. A generation ahead.

Most PET/CT scanners in India still use photomultiplier tubes — 1950s vacuum-tube technology that converts light into an electrical signal, losing a great deal of it along the way. The uMI Vista replaces those tubes with silicon photomultipliers: solid-state digital detectors that count individual light photons. More of the signal your body gives off actually reaches the image.

Take in less radiation

Higher sensitivity means we can achieve diagnostic images with a reduced injected dose — which compounds over a course of follow-up scans.

AI-assisted reconstruction

Deep-learning reconstruction suppresses noise without smoothing away the small lesions that matter, so lower-dose and shorter scans still read cleanly.

Pay no more for it

We priced the advantage in, not on top. There is no reason to accept an older-generation scan to save money — because you would not be saving any.

Point by point, against a conventional scanner

The right-hand column is the typical range for the analogue, photomultiplier-based PET/CT scanners still in routine service — a comparison of technology generations, not of any particular centre.

Detector technology

How the scanner turns your body's signal into a picture

Prismaa · Digital SiPM (silicon photomultiplier)

Conventional · Analogue PMT (photomultiplier tube)

Digital detectors count light photon by photon instead of averaging them, so far less of the signal is lost before it becomes an image.

Spatial resolution

The smallest lesion the scanner can resolve clearly

Prismaa · ≈ 2.9 mm

Conventional · ≈ 4 – 5 mm

Small deposits are found earlier — and in cancer, earlier detection is what changes the treatment plan.

Time-of-flight resolution

How precisely the scanner pinpoints where a signal came from

Prismaa · ≈ 302 picoseconds

Conventional · ≈ 500 – 550 picoseconds

Sharper localisation means less blur and better contrast — the difference is most obvious in larger patients, where conventional images go soft.

System sensitivity

How much of the signal the scanner actually catches

Prismaa · ≈ 12 cps/kBq

Conventional · ≈ 5 – 9 cps/kBq

Catching more signal is what allows either a shorter scan, a lower injected dose, or a sharper image — usually some of all three.

Scan time (whole body)

How long you lie still on the table

Prismaa · ≈ 15 minutes

Conventional · ≈ 25 – 30 minutes

Shorter scans mean less movement blur — and are far kinder to patients in pain, breathless, or unable to lie flat for long.

Injected radiation dose

How much radioactive tracer has to go in

Prismaa · Reduced protocols routinely possible

Conventional · Standard weight-based dose

A more sensitive detector needs less tracer for the same image quality — which matters most for young patients and anyone facing repeated follow-up scans.

CT component

The anatomical map PET is laid on top of

Prismaa · 160-slice, 0.3 s rotation

Conventional · 16 – 64 slice, 0.5 – 0.8 s rotation

A faster, finer CT means crisper anatomy, fewer breathing artefacts, and a diagnostic-quality CT in the same sitting.

Bore & comfort

What it feels like to be scanned

Prismaa · Wide bore, short ring, ambient lighting

Conventional · Narrower bore, longer acquisition

Nothing closes over your face. Claustrophobic and elderly patients get through the study far more comfortably.

Advanced molecular imaging

Tracers that lock on to one specific target

Standard PET follows sugar, which every busy cell consumes. Gallium-68 tracers are built differently: each is designed to fit one protein found on one kind of tumour cell — so the cancer lights up and almost nothing else does.

Why this matters to you

Several cancers are poorly seen on a standard sugar-based scan — prostate cancer, neuroendocrine tumours, and pancreatic and peritoneal disease among them. A targeted tracer is often the difference between a scan that finds the disease and one that reports nothing abnormal.

These studies are produced to order, so please give us a few days' notice when booking.

Beyond oncology

A PET/CT is not only for cancer

Roughly a fifth of the scans we perform are for something else entirely. If your neurologist, cardiologist or physician has asked for a PET/CT, this is why.

  • Neurology

    Memory loss, dementia and epilepsy

    MRI shows the brain's shape. PET shows how it is working — which is how Alzheimer's is told apart from frontotemporal or Lewy body dementia, and how the origin of drug-resistant seizures is located before surgery.

  • Cardiology

    Is this heart muscle worth operating on?

    After a heart attack, weakened muscle may be dead scar or alive but starved. On an echo they look identical; they demand opposite decisions. PET tells them apart before bypass surgery is agreed.

  • Infection & inflammation

    Weeks of fever and every test normal

    White cells fighting infection burn sugar just as tumours do. One whole-body scan finds the hidden abscess, the inflamed artery or the occult lymphoma — and shows the physician exactly where to biopsy.

Worries we hear most often

“A PET scan will give me cancer.”
The radiation from a PET/CT is comparable to a few years of the natural background radiation everyone receives from soil, food and cosmic rays. The risk from a scan is very small, and it is weighed against the far larger risk of treating a cancer blind. Our digital scanner lets us use lower doses than a conventional one requires.
“It is painful, or I will be trapped in a tunnel.”
There is one needle prick for the injection and nothing after that. The PET/CT ring is short and wide, open at both ends, and your face stays clear. It is nothing like an MRI tunnel.
“I will be radioactive and dangerous to my family.”
The tracer decays and washes out within hours. Ordinary contact with adults is safe the same day. We simply ask you to avoid prolonged close contact with pregnant women and infants until the next morning.
What is a PET/CT scan, in simple words?
It is two scans done at once. The CT half photographs your anatomy — the shape and position of every organ. The PET half shows which cells are working hardest, using a small amount of a tagged sugar injected into a vein. Overlaid on each other, they show your doctor not only where something is, but whether it is active. That is why PET/CT is the standard scan for staging cancer and for checking whether treatment is working.
What makes a digital PET/CT better than a conventional one?
Conventional scanners use photomultiplier tubes — analogue vacuum tubes that lose a lot of the signal on the way to the image. Our uMI Vista uses silicon photomultipliers, which count light photon by photon. In practice that means about 2.9 mm resolution instead of 4–5 mm, roughly 15 minutes on the table instead of 25–30, and the ability to use a lower injected dose. Smaller lesions are found, and they are found with less radiation and less time lying still.
Does a digital PET/CT cost more?
No. Prismaa charges the same as conventional PET/CT scans in Surat. We invested in the newer scanner rather than in a price premium, because there is no good reason for a patient to accept an older-generation scan simply to save money.
How long does the whole appointment take?
Plan for about two and a half hours in the centre. Most of that is the quiet resting hour after the injection, while the tracer distributes. The scan itself is around fifteen minutes.
Is the radiation dangerous?
The dose from a PET/CT is roughly comparable to a few years of natural background radiation. It is a real but small risk, and it is weighed against the much larger risk of planning cancer treatment without accurate information. Because our detector is more sensitive, we can often use less tracer than a conventional scanner would need for the same image quality.
Do I need a doctor's prescription to book a PET/CT?
Yes. A PET/CT should be requested by a treating doctor, because the right tracer and the right protocol depend on the clinical question. If you are unsure whether a scan is appropriate, call us and we will discuss it with your doctor.
Which scans do you offer besides cancer imaging?
PET/CT is also used for brain conditions such as dementia and drug-resistant epilepsy, for cardiac viability assessment before bypass surgery, and for tracking down hidden infection or inflammation in patients with prolonged unexplained fever. We also perform diagnostic 160-slice CT and CT-guided biopsies.
What advanced tracers are available at Prismaa?
Alongside standard 18F-FDG, we offer gallium-68 based molecular studies: PSMA for prostate cancer, DOTA-TATE/TOC/NOC for neuroendocrine tumours, and FAPI for cancers that FDG images poorly, such as pancreatic and peritoneal disease. Rarer tracers including Exendin-4 and Trivehexin can be arranged on request.
How soon will I get my report?
Most structured reports are released within 24 hours, and urgent studies faster. Reports use the standardised criteria your oncologist works with — RECIST 1.1, PERCIST, Deauville and others — so they can be compared directly against your previous scans.
Where exactly are you, and is parking available?
We are on the ground floor of the Zenon Building, opposite Unique Hospital, Surat-395002. Access is step-free from the street, and parking is available. Call +91 93169 25516 and we will guide you in.

Next at Prismaa

A complete theranostics centre

Imaging tells you where the disease is. The next step is treating it with the very same molecule — and we are building it.

We are commissioning a dual-head gamma camera and a dedicated radionuclide therapy suite. Together with our digital PET/CT, that will let one centre find the disease, confirm the target, and deliver the therapy — without patients travelling to another city between each step.

Dual-head gamma camera & SPECT/CT

Bone scans, thyroid and renal studies, cardiac perfusion, sentinel node mapping and DMSA — the everyday nuclear medicine that Surat currently sends patients out of the city for.

Radionuclide therapy suite

Shielded therapy rooms for I-131 for thyroid cancer, Lu-177 PSMA for advanced prostate cancer, and Lu-177 DOTA-TATE (PRRT) for neuroendocrine tumours.

Theranostics, end to end

Scan with gallium-68, confirm the target lights up, then treat with lutetium-177 attached to the same molecule. See it, then treat exactly what you saw.

Tell us your diagnosis and we will let you know as soon as the relevant service opens.
