Misconceptions about medical imaging can cause confusion or delay important screenings and diagnoses. Whether you are a patient, caregiver or healthcare provider, separating fact from fiction is essential for making informed health decisions.
Here are seven common myths about imaging — and the facts you need to know:
- Myth: All radiologists read the same types of studies.
Fact: At Fairfax Radiology, all radiologists are subspecialized, meaning each focuses on specific areas of the body or types of imaging. This ensures every exam is reviewed by an expert with deep knowledge in that specialty. For example, breast imaging radiologists are fellowship-trained and interpret only breast imaging studies every day. This focus, combined with advanced technology, helps detect cancer earlier and more accurately than national and regional averages. - Myth: A clear mammogram means there’s nothing to worry about.
Fact: While a negative mammogram is reassuring, it does not always tell the full story. In patients with dense breast tissue, some abnormalities may be harder to detect. Supplemental imaging such as ultrasound or MRI may be recommended based on risk factors and screening history. - Myth: All imaging exposes patients to high levels of radiation.
Fact: Radiation exposure varies by type of imaging. Tests such as MRI and ultrasound use no ionizing radiation. When radiation is involved, as with X-rays or CT scans, strict guidelines are followed to keep doses as low as possible. For example, low-dose CT scans used for lung cancer screening deliver significantly less radiation while still providing lifesaving information. - Myth: Mammograms are only necessary if you feel a lump.
Fact: Waiting until a lump is palpable may mean the cancer has progressed. Screening mammograms are designed to find cancer early — before symptoms develop — when treatment is most effective. Annual screening is recommended starting at age 40, or earlier for those at higher risk. - Myth: MRIs expose patients to radiation.
Fact: MRI uses magnetic fields and radio waves — not radiation — making it a safe and powerful tool to image soft tissues, neurological conditions, joints and more. - Myth: You only need imaging after something is wrong.
Fact: Many imaging exams are preventative, designed to catch disease early, before symptoms appear. Screening tests such as mammograms, coronary calcium scoring and lung cancer screening help detect conditions early, leading to better treatment options and outcomes. - Myth: Ultrasound is just for pregnancy.
Fact: Ultrasound is a versatile, radiation-free imaging method used far beyond pregnancy. It helps evaluate the abdomen, breast, thyroid, blood vessels, muscles and joints — offering quick and safe insight into many health conditions.
