Why PET-CT Prices Vary — Between Centres

Most Indian health insurance policies cover PET-CT when it is recommended in writing by an oncologist and the centre is on the insurer's network. The key step is pre-authorisation: contact your insurer before you book, not after, and get the approval number in writing. Some policies cap the PET-CT benefit at a fixed amount per year, which may not cover the full cost at premium centres. Ask your insurer about the cap and whether the centre you are considering is cashless-enabled under your specific policy.

Not automatically. Scanner generation does vary between centres, and a higher-specification machine can produce sharper images — useful in complex staging. But the reporting specialist matters more than the machine generation for most oncology questions. A lower-cost centre may have a current-generation scanner and a general radiologist; a higher-cost centre may have the same scanner and a nuclear medicine physician. Ask both questions separately rather than using price as a proxy for machine quality.

Aarogyasri and similar state schemes cover PET-CT for eligible patients when it is pre-authorised for a covered indication. The scheme sets a ceiling on what it reimburses, and not every centre is empanelled under it. Check whether the centre you are considering is an Aarogyasri-empanelled facility and whether your specific indication is covered before you book. Your oncologist or the hospital's insurance help desk can confirm both.

The report will carry the reporting doctor's name and qualifications at the end. Before you book, ask the centre directly: 'Is the PET-CT reported by a nuclear medicine physician, or by a general radiologist?' A centre with a nuclear medicine specialist will say so clearly. If the answer is vague, that is information. You can also ask your oncologist whether the reporting standard at a particular centre is adequate for your specific clinical question — they will usually have a view.

The FDG tracer used in most PET scans is radioactive for a very short time. The radiation dose is considered acceptable for clinical use under AERB and IAEA safety standards. The tracer clears from your body quickly, mainly through urine. You will be asked to stay away from young children and pregnant women for a few hours after the scan — your centre will give you specific instructions. If you are pregnant or breastfeeding, tell your team before booking; the timing may need to change.

For scans intended to track your response to treatment, your oncologist will compare images directly with the previous scan. Having the follow-up done at the same centre, on the same scanner, with the same protocol, makes that comparison more reliable. Differences in machine type, slice thickness, and image reconstruction between centres can make it harder to judge whether a change in a lesion is real or an artefact of different equipment. If you have to change centres, tell your oncologist so they can account for it.
