Computed Tomography (CT) Imaging

• What it is: CT scans use X-rays and computers to produce detailed cross-sectional
  images of the body.
• What to expect: You will lie on a padded table that moves through the scanner. The procedure is fast and designed to minimize discomfort, even for children and seniors.
• Why it’s important: Provides precise images to help your doctor diagnose conditions accurately and efficiently.
• Who performs it: Certified technologists guide you through every step for a smooth, reassuring visit.

All of these services are offered through using state-of-the-art equipment and are provided by highly-trained, professional technologists. Another way Mason District Hospital is High-Tech, High-Touch.

Dual-Energy X-Ray Absorptiometry (DEXA)

• What it is: Measures bone density to detect osteoporosis and assess fracture risk.
• What to expect: You will lie on a padded table for about 25 minutes. Safe, painless, no special preparation, and no clothing changes required.
• Why it’s important: Helps your doctor evaluate bone health and develop a plan to reduce fracture risk.
• Who is at risk: Family history of osteoporosis, low body weight, low calcium intake, smoking, mobility issues, hyperthyroidism, age.

Magnetic Resonance Imaging (MRI)

• What it is: MRI uses magnets, radio waves, and computers to create detailed images
  of organs, tissues, and bones.
• What to expect:
  • You will lie on a padded table that slides into a large magnet.
  • Non-invasive, no radiation exposure.
• Who performs it: Mobile Imaging services with a high-frequency, high-field 1.5 Tesla MRI unit.
• Coming soon: Permanent MRI in 2026!

Mammography

• What it is: Digital Mammography uses low-dose X-rays to create images for early
  detection of breast abnormalities.
• What to expect:
  • The scan is quick and performed by a certified technologist.
  • Images are shared immediately with your physician for faster results.
• When to start: Annual screening is recommended starting at age 40 by leading health organizations.
• Who performs it: Certified mammographers committed to patient comfort and accurate results.

Nuclear Medicine

• What it is: Uses a very small amount of radioactive material to examine organ function
  and detect abnormalities.
• Types of exams:
  • Single Photon Emission Computed Tomography (SPECT)
  • Whole-body scans
  • Cardiac imaging with stress tests
  • Thyroid imaging and treatment
• Why it’s important: Assesses kidney function, heart blood flow, lung health, gallbladder, bones, and detects cancer.
• Who performs it: Certified nuclear technologists dedicated to patient comfort and care.

Positron Emission Tomography – Computed Tomography (PET-CT)

• What it is: Combines PET (shows body function) and CT (shows body structure) for a
  complete diagnostic view.
• What to expect:
  • The PET tracer may be injected, swallowed, or inhaled depending on the exam.
  • The CT scan produces detailed images to locate abnormalities.
• Why it’s important:
  • Detect and monitor cancer
  • Evaluate brain disorders such as Alzheimer’s, epilepsy, or tumors
  • Assess heart disease and blood flow
• Who performs it: Mobile imaging services with a GE Discovery integrated PET and CT scanner in one gantry.

Ultrasound

• What it is: Ultrasound (sonography) uses high-frequency sound waves to create
  images of your body.
• What to expect:
  • A gel is applied to the skin and a handheld probe is moved across the area.
  • Non-invasive, painless, and safe for adults, children, and babies.
• Why it’s important: Provides real-time images for diagnosing a variety of conditions.

X-Ray

• What it is: X-rays use a focused beam of photons to produce images of bones and soft
  tissues.
• What to expect:
  • Quick, painless imaging.
  • Some exams may require specific positioning, guided by a technologist.
• Why it’s important: Commonly used to detect broken bones and other conditions.
• Who performs it: Highly trained technologists ensuring safe, accurate imaging.
