Medical imaging has revolutionized modern healthcare, giving doctors the ability to detect, diagnose, and monitor countless conditions with accuracy that wasn’t possible just decades ago. However, despite these advancements, many patients still feel uneasy about scheduling imaging exams — often because of misinformation or outdated myths.

At GLMI, we believe that informed patients make confident decisions. That’s why we’re addressing some of the most common myths about medical imaging and explaining the truth behind them. If you live in Buffalo, Williamsville, Cheektowaga, Orchard Park, or Cambria, here’s what you should know before your next scan.

Myth #1: Imaging Tests Expose You to Unsafe Levels of Radiation

Fact: Modern imaging technology uses extremely low doses of radiation — often comparable to what you’re exposed to naturally in the environment over a short period of time. At GLMI, our low-dose CT scans and other radiology services use advanced equipment designed to minimize exposure while maintaining exceptional image clarity.

In fact, for most patients, the diagnostic benefit of imaging far outweighs the minimal radiation involved. Our radiologists and technologists follow the “ALARA” principle — As Low As Reasonably Achievable — ensuring that every scan is performed safely, efficiently, and only when medically necessary.

Myth #2: Imaging Tests Are Only for People Who Are Sick

Fact: Imaging isn’t just for diagnosing illness — it’s a key part of preventive healthcare. Many serious conditions, such as vascular disease, osteoporosis, and certain cancers, develop silently without symptoms. Preventive imaging helps identify early changes in the body so doctors can intervene before problems worsen.

Services like bone densitometry or ultrasound screenings can detect issues early, supporting better outcomes and less invasive treatments. Imaging plays a major role in keeping patients healthy — not just diagnosing them once they’re sick.

Myth #3: All Imaging Tests Are the Same

Fact: Different types of imaging serve very different purposes. Each uses unique technology to capture specific details about your body. For example:

• Ultrasound uses sound waves to evaluate blood flow, soft tissue, and organs — with no radiation at all.
• CT scans use X-rays to create detailed cross-sectional images of internal structures like the lungs, arteries, or bones.
• PET/CT scans combine two technologies to detect both anatomical and metabolic activity, helping doctors assess cancer, infection, and inflammation.
• Nuclear medicine evaluates how organs and tissues are functioning at a molecular level.

Each imaging test provides unique insights, and your doctor chooses the best one for your condition — there’s no “one-size-fits-all” in medical imaging.

Myth #4: Imaging Tests Are Painful or Uncomfortable

Fact: Most imaging exams are completely painless and non-invasive. You may need to lie still for a few minutes, but there’s no discomfort or recovery time involved. Exams like ultrasound or bone density scans feel similar to a routine checkup.

Even imaging that uses contrast dye — such as a CT scan or interventional radiology procedure — typically involves only a brief warm sensation or metallic taste, which passes quickly. Our technologists explain every step before your scan so you know exactly what to expect.

Myth #5: Imaging Results Take Weeks to Receive

Fact: While older systems once required long turnaround times, modern digital imaging allows results to be processed and reviewed quickly. At GLMI, our state-of-the-art technology ensures that your images are ready for interpretation promptly, and reports are sent directly to your referring physician as soon as possible.

Your doctor can then discuss the findings with you — often within just a few days. Faster results mean faster answers and faster peace of mind.

---

Myth #6: You Should Avoid Imaging if You’re Older

Fact: Preventive imaging becomes more valuable as we age. Age-related conditions such as vascular disease, osteoporosis, and certain cancers are best managed through early detection. Imaging allows doctors to identify and monitor changes that could otherwise remain hidden until symptoms appear.

For example, bone density testing helps prevent fractures, while vascular ultrasound can detect circulation problems before they become serious. Regular, low-dose imaging supports healthy aging and promotes independence.

---

Myth #7: All Imaging Centers Offer the Same Quality

Fact: Imaging quality varies widely depending on the technology, equipment calibration, and radiologist expertise. Low-quality images can lead to unclear results or even missed diagnoses. That’s why choosing a trusted imaging provider matters.

GLMI invests in advanced imaging systems, including PET/CT, nuclear medicine, and low-dose CT, maintained and operated by highly trained technologists. Our board-certified radiologists specialize in precise, reliable interpretation, ensuring the highest standards of accuracy for every patient.

---

Myth #8: Imaging Is Too Expensive to Be Preventive

Fact: Preventive imaging is one of the most cost-effective tools in modern healthcare. By detecting disease early, imaging often prevents the need for expensive emergency treatments, surgeries, or hospital stays down the road. Many insurance plans also cover medically necessary or preventive imaging — especially for patients with risk factors such as age, family history, or chronic conditions.

At GLMI, our staff helps patients navigate insurance questions to ensure they receive the imaging care they need without financial surprises.

---

Myth #9: You Can Skip Imaging If You Feel Fine

Fact: Many conditions don’t show symptoms until they’re advanced — including heart disease, cancer, and vascular disorders. Imaging helps doctors identify issues long before they cause pain or discomfort. Feeling fine doesn’t always mean you’re in the clear.

Preventive screenings — like low-dose CT scans or ultrasound evaluations — can reveal early warning signs that allow for fast, effective treatment and long-term wellness.

---

Myth #10: Imaging Isn’t Necessary After Treatment

Fact: Imaging plays a vital role even after treatment or surgery. Follow-up scans confirm healing, check for recurrence, and ensure that medical devices or implants are functioning properly. For chronic conditions, repeat imaging helps track stability and ensure ongoing health.

Regular post-treatment imaging allows doctors to adjust care plans as needed and prevent complications before they arise.
