——————————————————————————–
A PET scan (positron emission tomography) is one of the most powerful diagnostic imaging tools available, but the cost of a PET scan can be a real financial concern. Prices vary widely by facility, the part of the body being scanned, the tracer used, and your insurance — so any single number is only a rough guide. As a broad estimate for 2026, a self-pay PET/CT scan often falls somewhere between about $1,300 and $7,600 or more, with national averages commonly cited in the low-to-mid four figures. Where you land within that range depends heavily on where you have the scan.
Whether your doctor has recommended a PET scan for cancer staging, cardiac evaluation, or a neurological assessment, understanding the cost of a PET scan beforehand can help you plan and explore ways to reduce your out-of-pocket expense.
What Is a PET Scan?
A positron emission tomography (PET) scan is an imaging test that uses a small amount of radioactive tracer to show how your tissues and organs are functioning. Unlike CT scans or MRIs, which mainly show anatomical structure, PET scans reveal metabolic activity, making them especially valuable for detecting cancer, evaluating heart conditions, and assessing certain brain disorders.
Most modern PET scans are performed as combined PET/CT scans, which overlay metabolic data on detailed anatomical images for greater diagnostic accuracy. According to the National Cancer Institute, PET/CT is a standard tool in oncology for staging cancer, monitoring treatment response, and detecting recurrence.
PET Scan Cost Without Insurance
The self-pay cost of a PET scan varies based on the type of scan, the facility, and your location. The ranges below are 2026 estimates, not fixed prices — always request a specific quote from the facility:
PET/CT scan (most common): roughly $1,300 to $7,600+. This combined scan is the standard for most oncology, cardiac, and neurological applications, and it shows the widest spread because of facility type. PET-only scan: roughly $1,000 to $3,000. Standalone PET scans are less common today but may be used in specific situations. Brain PET scan: roughly $2,000 to $5,000+. Specialized brain PET (for Alzheimer’s disease, epilepsy, or brain tumors) can cost more due to specialized tracers. Cardiac PET scan: roughly $2,000 to $5,000+. Used to evaluate blood flow to the heart and detect coronary artery disease.
The radioactive tracer itself accounts for a significant portion of the cost and is sometimes billed as a separate line item. FDG (fluorodeoxyglucose) is the most common tracer, but specialized tracers for specific conditions can raise the price substantially. The radiologist’s interpretation fee is usually included but may be billed separately at some facilities, so ask whether the quoted price is all-inclusive.
PET Scan Cost With Insurance
Most health insurance plans, including Medicare, cover PET scans when they are medically necessary and ordered by a physician for a covered indication. The Medicare Coverage Database and national/local coverage determinations specify which oncologic, cardiac, and neurologic uses are covered. Coverage is generally tied to the clinical indication, so a scan for an approved cancer, cardiac, or neurologic reason is far more likely to be paid than one ordered outside accepted criteria.
With commercial insurance, your out-of-pocket cost depends on your deductible, coinsurance, copay, and whether the facility is in-network — it can range from a modest copay to a four-figure amount if you have not met your deductible. Under Original Medicare, PET scans are generally covered under Part B, and after you meet the Part B deductible you typically pay 20% coinsurance of the Medicare-approved amount; the exact figure depends on the site of service and the year’s fee schedule. Medicare Advantage plans set their own cost-sharing and network rules. In nearly all cases, prior authorization is required, so make sure your doctor’s office secures approval before the scan is scheduled — an unauthorized scan can be denied, leaving you responsible for the bill.

Factors That Affect PET Scan Pricing
The facility type has the biggest impact on price. Hospital outpatient departments can charge two to three times more than freestanding imaging centers because of facility fees. The identical PET/CT scan that costs $2,000–$3,000 at an independent imaging center can run well into five figures of billed charges at a hospital — though what you actually pay depends on your coverage and any negotiated rates.
Geographic location also matters: areas with a higher cost of living tend to have higher imaging prices. The type of tracer affects cost, since newer or specialized tracers are more expensive to produce and have short shelf lives. Whether the scan runs on a fixed scanner or a mobile PET unit can influence pricing as well. And the body area scanned matters — a targeted study can differ in price from a whole-body oncology scan.
How to Save on a PET Scan
Ask for a good-faith estimate: If you are uninsured or paying cash, federal No Surprises Act rules generally entitle you to a good-faith estimate of expected charges in advance. Request one in writing so you can compare and plan.
Consider a freestanding imaging center: If your doctor agrees, an independent imaging center rather than a hospital can save you a substantial amount. Many use comparable equipment and employ board-certified radiologists — confirm accreditation and that the results will be accepted by your care team.
Confirm prior authorization: Ensure your insurer approves the scan before it is performed; without authorization, your claim could be denied.
Compare cash prices: Call multiple facilities and ask for self-pay rates. Insurer and third-party price-transparency tools can also help you compare.
Ask about financial assistance: Many hospitals have charity care or financial-assistance programs; nonprofit hospitals are generally required to offer them.
Negotiate the bill: If you receive a large bill, contact the billing department. Many facilities offer discounts for prompt payment or demonstrated need.
Check financing options: Programs such as CareCredit can spread the cost over time, sometimes with promotional interest-free periods — read the terms carefully.
What to Expect During a PET Scan
A PET scan appointment typically takes two to three hours total, though the scan itself often lasts only 20 to 40 minutes. You will receive the radioactive tracer through an IV injection about an hour before the scan to let it distribute through your body, then lie still on a table while the scanner captures images.
Preparation usually involves fasting for several hours before the scan and avoiding strenuous exercise beforehand. People with diabetes may need special instructions on blood-sugar management. The radiation exposure is low and the tracer clears from your body within hours; follow your care team’s specific instructions.
Frequently Asked Questions
Is a PET scan dangerous?
PET scans involve a small amount of radiation, but the dose is considered acceptable for diagnostic purposes. According to RadiologyInfo.org (from the RSNA and ACR), the radiation exposure from a typical PET/CT scan is comparable to what a person receives from natural background radiation over a period of a few years. For most patients, the diagnostic benefit outweighs the small risk, but discuss any concerns — including pregnancy or breastfeeding — with your doctor.
How long does it take to get PET scan results?
Results are typically available within one to three business days. A radiologist reviews the images and sends a report to your ordering physician, who will discuss the findings with you. In urgent cases, preliminary results may be available sooner.
Why is a PET scan so expensive?
Several factors contribute. The radioactive tracer must be produced in a cyclotron and has a very short shelf life, making it costly to manufacture and deliver on a tight schedule. The scanning equipment costs millions of dollars, and the procedure requires specialized nuclear-medicine technologists and radiologists. Hospital facility fees add further to the total.
Can I get a PET scan without a doctor’s order?
No. PET scans require a physician’s order because they involve radioactive materials and the results require medical interpretation. Your doctor determines whether a PET scan is clinically appropriate based on your symptoms, diagnosis, and treatment plan.
Does insurance always cover a PET scan?
Not automatically. Coverage generally applies when the scan is medically necessary for an approved indication and prior authorization is obtained. Scans ordered outside accepted criteria may be denied. Always verify coverage with your specific plan before scheduling.
Making Your PET Scan More Affordable
The cost of a PET scan is significant, but it provides information that can directly shape your treatment plan and outcomes. By choosing an appropriate facility, securing insurance prior authorization, requesting a good-faith estimate, and exploring financial assistance, you can reduce your financial burden while getting the imaging your doctor recommends. Do not let cost concerns keep you from a necessary scan — instead, advocate for yourself by comparing prices, confirming coverage, and asking about every available discount.
TL;DR: PET/CT scan prices vary widely — often about $1,300 to $7,600+ self-pay in 2026 — driven mostly by facility type, body area, and tracer. Insurers and Medicare generally cover medically necessary scans for approved oncology, cardiac, and neurologic indications, usually with prior authorization; with Medicare Part B you typically pay 20% after your deductible. Get a good-faith estimate and verify coverage with your facility and plan before scheduling.
