How Much Does a PET Scan Cost in 2026? Complete Price Guide

Your oncologist or cardiologist has ordered a PET scan. Before you schedule, you should know that the price gap between a hospital and an outpatient imaging center for the exact same PET scan can exceed $5,000 — and insurance pre-authorization is mandatory in almost every case. Understanding PET scan pricing before you book can save you a substantial amount of money.

PET vs. PET/CT: What's the Difference?

Most modern PET scanners are combined PET/CT machines — they simultaneously capture PET metabolic data and CT anatomical data in a single session. A standalone PET scan (without CT) is rarely performed today. When your physician orders a "PET scan," they almost always mean a PET/CT. This distinction matters because:

Factor	PET-only	PET/CT (Combined)
What it provides	Metabolic activity map only	Metabolic activity fused with anatomical CT images
Clinical use today	Rarely ordered standalone	Standard of care for oncology, cardiac, neurology
Scan duration	45–60 minutes	60–90 minutes (includes uptake wait time)
Typical cash price (imaging center)	$1,500–$3,500	$2,000–$5,500
Insurance billing	Separate CPT codes for PET + CT	Combined PET/CT CPT code (higher reimbursement)

PET Scan Costs by Use Case (2026)

The reason for your PET scan — oncology, cardiology, or neurology — significantly affects both the type of tracer used and the price. Oncology PET scans (which use FDG, a glucose-based tracer) are the most common and widest-ranging in price; cardiac PET scans use different tracers and specialized protocols.

Oncology PET Scan Costs

The most common PET scan use case. FDG (fluorodeoxyglucose) tracer lights up cancer cells that consume glucose at higher rates than normal tissue. Used for initial staging, treatment response monitoring, and surveillance after treatment.

Scan Type	Imaging Center (Cash)	Hospital (List Price)
Whole Body PET/CT (skull to thigh)	$2,500–$5,500	$5,500–$9,500
Limited Body PET/CT (chest/abdomen/pelvis)	$2,000–$4,500	$4,500–$8,000
Brain PET (FDG — dementia/tumor)	$1,400–$2,500	$3,000–$6,000
Head & Neck PET/CT	$2,200–$4,800	$4,800–$8,500
Lymphoma Staging PET/CT	$2,500–$5,000	$5,200–$9,000

Cardiac PET Scan Costs

Cardiac PET scans assess heart muscle viability, blood flow, and function. They use rubidium-82 or ammonia tracers rather than FDG. A cardiac PET scan is used to evaluate coronary artery disease, determine if damaged heart muscle is viable before revascularization surgery, and diagnose cardiac sarcoidosis.

Scan Type	Outpatient Cardiology / Imaging Center	Hospital (List Price)
Cardiac PET (rest only)	$1,200–$2,200	$2,800–$5,500
Cardiac PET (stress/rest — myocardial perfusion)	$1,800–$3,200	$3,500–$7,000
Cardiac PET/CT (calcium scoring included)	$2,000–$3,800	$4,000–$7,500
FDG Cardiac PET (sarcoidosis/inflammation)	$2,200–$4,000	$4,500–$8,000

Hospital vs. Outpatient Imaging Center for PET Scans

For PET scans specifically, the facility type difference is even more dramatic than for MRI or CT. PET scanners are expensive capital equipment, and hospital billing structures add facility fees that can double or triple the final cost for the exact same scan.

Factor	Hospital Outpatient	Independent Imaging Center
Typical Price (Whole Body PET/CT)	$5,500–$9,500	$2,500–$5,500
Facility Fee Added	Yes — often $2,000–$4,000	No separate facility fee
Tracer/Radiopharmacy	Billed separately or bundled	Usually included in quoted price
Nuclear Medicine Physician	Billed separately	Usually included or separate
Scheduling	Days to weeks wait	Often within days
Best For	Complex cases, inpatient workups, pediatric oncology	Scheduled oncology staging/surveillance, cardiac PET

Insurance Coverage and Prior Authorization for PET Scans

PET scans are covered by most commercial insurance plans and Medicare — but pre-authorization is non-negotiable. Skipping this step means you could owe the full billed amount, which at a hospital can exceed $9,000.

Prior authorization: what's required

Your physician must submit documentation including: the clinical indication (cancer type and stage, cardiac symptoms, neurological findings), the specific clinical question the PET is meant to answer, prior imaging results, and pathology reports if applicable. For oncology PET scans, most insurers require documentation that the result will directly change the patient's management plan.

Medicare coverage for PET scans

Medicare Part B covers PET scans for a defined list of covered diagnoses. Coverage is generally available for:

• Oncology: Initial staging for breast, colorectal, esophageal, head/neck, thyroid, lymphoma, melanoma, lung, cervical cancer, and others. Also covers treatment response monitoring and restaging for most solid tumors and lymphomas.
• Cardiology: Myocardial viability assessment when planning revascularization in patients with coronary artery disease and left ventricular dysfunction.
• Neurology: Brain FDG PET for Alzheimer's disease diagnosis (under specific coverage criteria) and pre-surgical evaluation for refractory epilepsy.

Your typical Medicare out-of-pocket: 20% of the Medicare-approved amount after your Part B deductible. At an outpatient imaging center, the approved amount may be $2,000–$3,500, making your share $400–$700. At a hospital outpatient department, the approved amount and your 20% will be higher.

What you'll typically pay with commercial insurance

• After meeting deductible: Coinsurance only (typically 20–30%). On a $3,000 imaging center PET/CT, that's $600–$900.
• Before meeting deductible: You pay the full negotiated rate. At a hospital, this can still be $3,000–$6,000 even with insurance negotiation. At an imaging center, the negotiated rate may be $1,800–$3,500.
• Out-of-network: Without prior auth at an out-of-network facility, you may owe the full billed amount with no insurance discount — potentially $7,000–$12,000.

What Makes a PET Scan Expensive?

PET scans are among the most expensive outpatient imaging studies. Several factors combine to produce the high price tag:

• The radiotracer cost — FDG is produced at a cyclotron facility and has a 2-hour half-life, requiring same-day delivery. Tracer cost alone is typically $300–$800 per dose and is often billed separately.
• PET/CT scanner cost — These machines cost $2–3 million and require specialized shielding rooms, increasing facility overhead significantly compared to MRI.
• Nuclear medicine specialist — A specially trained physician interprets PET scans, often billed at $400–$800 separately from the facility fee.
• Body area and tracer type — Whole body scans use more tracer than limited scans; specialized tracers for cardiac and neurological PET cost more than standard FDG.
• Hospital facility fee — As with all hospital-based imaging, the facility fee can add $2,000–$4,000 to the base scan cost.

How to Lower Your PET Scan Cost

1. Get prior authorization confirmed before scheduling

This is not optional. Contact your physician's office to verify the authorization is in hand before you schedule at any facility. Most authorizations take 3–7 business days and are valid for 60–90 days. Some imaging centers will initiate the auth process on your behalf if you provide your physician's contact information.

2. Compare outpatient imaging centers to hospital outpatient

For scheduled, non-emergency PET scans with a prior auth already obtained, an accredited outpatient imaging center will almost always cost significantly less than a hospital. Use price transparency tools to compare in-network options in your area before calling to schedule.

3. Ask for an all-inclusive price estimate

PET scan billing is notoriously fragmented. Ask explicitly: "What is the total cost including the tracer, facility fee, and physician interpretation?" Get this in writing before you proceed. Some facilities provide bundled cash prices that are substantially lower than the sum of individual billed components.

4. Check for hospital financial assistance programs

If your PET scan is ordered as part of cancer care at a major hospital system, financial counselors can sometimes reduce or waive costs based on income. This is especially relevant for patients who are uninsured or underinsured.

5. Use price transparency data

Federal price transparency rules require hospitals to publish PET scan prices. CarePrices aggregates this data across 6,500+ facilities with 5 billion+ data points so you can compare PET scan costs in your area — including the hospital vs. imaging center gap — before you ever pick up the phone.

What to Expect During Your PET Scan

• Preparation (oncology FDG PET): Fast for 4–6 hours before the scan. Avoid strenuous exercise for 24 hours — muscle activity increases glucose uptake and can create false signals. If you have diabetes, special protocols are required; inform your physician and the imaging center in advance.
• Tracer injection: You'll receive an IV injection of the radiotracer and then wait 45–90 minutes in a quiet room while the tracer circulates and is absorbed by metabolically active tissue.
• The scan itself: You'll lie still on a table that moves through the PET/CT scanner — similar in appearance to a CT machine, wider bore than most MRI. The scan takes 20–40 minutes depending on coverage area.
• Radiation exposure: A PET/CT scan involves radiation from both the radiotracer and the CT component. The effective dose is comparable to a diagnostic CT scan. The radiotracer loses its radioactivity within hours.
• Results timeline: A nuclear medicine physician or radiologist reads the images and sends a report to your ordering physician, typically within 24–48 hours. For urgent oncology cases, same-day results are sometimes available.

PET Scan vs. CT Scan vs. MRI: Which Is Right?

Your physician chooses among these based on what clinical question needs to be answered:

• CT scan ($270–$5,500): Best for anatomy — finding tumors, measuring their size, identifying metastases to lymph nodes or organs. Fast, widely available, lower cost.
• MRI ($475–$4,800): Best for soft tissue detail — brain tumors, spinal cord, liver lesions, prostate. No radiation. Slower and more expensive than CT.
• PET scan ($1,200–$9,500): Best for metabolic activity — distinguishing active cancer from scar tissue, detecting cancer spread not yet visible on CT, assessing treatment response, cardiac viability. Significantly more expensive than CT or MRI and requires prior auth.

The Bottom Line

A PET scan is one of the most powerful diagnostic tools in oncology and cardiology — and one of the most expensive outpatient imaging studies you can have. The price gap between a hospital outpatient PET scan and an independent imaging center can exceed $5,000 for the identical scan, driven primarily by hospital facility fees and overhead rather than any difference in clinical quality.

The critical steps: secure prior authorization before scheduling, request an all-inclusive price estimate (tracer + facility + physician interpretation), and compare outpatient imaging centers to hospital pricing. Those three actions are typically the difference between a manageable out-of-pocket cost and a five-figure surprise bill.
