InflammationIQ™ PET/CT Scan

See Where Inflammation is
Hiding in Your Body

PET/CT imaging helps localize areas of increased metabolic activity that may correspond to inflammation, infection, or immune-related disease — revealing what may not be clearly identified with blood tests or structural imaging alone.

Physician-Led Interpretation

All imaging reviewed by experienced radiologists. Report delivered within 24–48 hours.

Advanced Imaging Technology

Metabolic PET combined with high-resolution CT — function and anatomy in a single scan.

The Technology

The same clinical signal — but now you can see exactly where

Traditional labs and blood panels can confirm that inflammation exists. But they can't tell you which organ, which lymph node, or which tissue is under attack.

PET/CT bridges that gap. By tracking how your cells use energy, it creates a precise metabolic map of where disease is active — right now, in your body.

  • Can reveal metabolically active inflammation that may not be clearly visible on structural imaging alone
  • Highlights lymph nodes with increased metabolic activity that may reflect inflammation or immune activation
  • May help assess whether metabolically active inflammation is responding to treatment over time
  • Often helps distinguish metabolically active disease from inactive scar tissue

How PET + CT Work Together

PET
Function
Tracks metabolic activity. Cells with increased glucose consumption — including inflamed, infected, or malignant tissue — absorb more of the FDG tracer.
+
CT
Structure
Maps precise anatomy — organs, vessels, lymph nodes, and bones — in high detail.
Combined result: You see not just that increased metabolic activity exists, but exactly which tissue or organ it's in. Increased FDG uptake must be interpreted in clinical context by your physician, as it can reflect inflammation, infection, or malignancy.
The Process

What Happens During Your PET/CT Scan

The entire process typically takes 2–3 hours, most of which is simply waiting for the tracer to distribute through your body.

Tracer Injection

A small dose of FDG (fluorodeoxyglucose) — a mildly radioactive glucose analog — is injected. It's safe, and most of the tracer decays and is cleared from the body within several hours.

Uptake Period (~60 min)

You rest quietly for about an hour as the tracer distributes through your body. Hyperactive cells — inflamed, infected, or malignant — absorb more of it.

The Scan (~30 min)

You lie still on a table as the scanner detects gamma ray signals from the tracer. The CT runs simultaneously for structural context. No tube, no claustrophobia for most patients.

Why Not Just…

Traditional Imaging Comes With Blind Spots

Most imaging tests were designed to find structural problems. Autoimmune disease is a functional problem — which is why it often goes undetected for years.

Who May Benefit

Conditions Where PET/CT Changes the Picture

If you or your physician are working to localize the source of systemic inflammation, PET/CT can provide additional insight when conventional testing is inconclusive.

Vasculitis

Large-vessel vasculitis can be difficult to fully assess with structural imaging alone. PET/CT can detect metabolically active inflammation in major vessels such as the aorta and its branches.

Sarcoidosis

PET/CT helps evaluate the extent of active disease and may identify occult sites, supporting biopsy targeting.

Lupus (SLE)

PET/CT may help identify areas of active inflammation when organ involvement is unclear or other imaging is inconclusive.

IgG4-Related Disease

PET/CT can help identify multi-organ involvement and may be useful in assessing treatment response.

Inflammatory Bowel Disease

In select cases, PET/CT may demonstrate active inflammation and help evaluate disease beyond the gastrointestinal tract.

Unexplained FUO / Systemic Symptoms

Fever of unknown origin, persistent fatigue, or elevated inflammatory markers with no clear source — PET/CT can help identify potential underlying causes when initial workup is inconclusive.

Questions We Hear Often

Frequently Asked Questions

Is PET/CT safe? Am I exposed to a lot of radiation?
The radiation exposure from a PET/CT scan is comparable to other standard diagnostic imaging procedures and is considered medically acceptable. The FDG tracer has a short half-life of approximately 110 minutes, and most of the tracer decays and is cleared from the body within several hours. Your physician will weigh the diagnostic benefit against any risk before ordering the scan.
Do I need a doctor's referral to schedule a scan?
In many cases you can schedule directly, but a physician order is typically required for the scan itself. Our team can walk you through the process and advise on the best path based on your situation. Call us at 212-636-7315 for guidance.
Is this covered by insurance?
Insurance coverage for PET/CT varies by plan and indication. Our team will work with you to verify benefits prior to your appointment. We also offer self-pay pricing options — contact us for details.
How is this different from a regular CT or MRI?
Standard CT and MRI show the structure of your body — they reveal what things look like. PET shows function — how your tissues are metabolically behaving. Combined, PET/CT tells you both where something is and what it's actively doing. For inflammatory and autoimmune conditions, this functional layer is often where the diagnosis lives.
How soon will I get my results?
A board-certified radiologist reviews your images within 24–48 hours of your scan. There is no waitlist. You will receive a detailed written report that you can share with your treating physician.
Can PET/CT tell me if my treatment is working?
In some inflammatory diseases, repeat PET/CT scans may help evaluate whether metabolically active inflammation is increasing, decreasing, or spreading over time. By comparing scans, your physician can gain objective metabolic evidence of how disease is responding — information that blood markers alone may not fully capture. Your physician will determine whether serial imaging is appropriate for your condition.

Stop guessing where the inflammation is.

PET/CT gives your doctor a metabolic map of your immune system. Next-day appointments available in Midtown Manhattan.
