Key Benefits of Radiology That You Should Know


Information provided by the

At ADC, our Diagnostic Imaging Department is equipped to provide a wide range of radiology services. These services include CT Scans, General and Vascular Ultrasonography, Bone Density testing and EKG’s. All studies are interpreted by independent radiologists who are board-certified by the American Board of Radiology. Listed below are the key benefits of each test and what it can do for the body.

CT Scans

A computed tomography (CT) of the body uses special x-ray equipment to help detect a variety of diseases and conditions. CT scanning is fast, painless, noninvasive and accurate. In emergency cases, it can reveal internal injuries and bleeding quickly enough to help save lives.

Benefits of CT include:

  • Determining when surgeries are necessary
  • Reducing the need for exploratory surgeries
  • Improving cancer diagnosis and treatment
  • Reducing the length of hospitalizations
  • Guiding treatment of common conditions such as injury, cardiac disease and stroke

General/Vascular Ultrasonography

Vascular ultrasounds use sound waves to test the body’s circulatory system to help identify blockages and detect blood clots. A Doppler ultrasound study is a technique that evaluates blood flow through a blood vessel. An ultrasound does not use ionizing radiation, has no known harmful effects, and provides a clear picture of soft tissues that don’t show up well on x-ray images.

Benefits of a ultrasonography include:

  • Most ultrasound scanning is noninvasive (no needles or injections).
  • Occasionally, an ultrasound exam may be temporarily uncomfortable, but it is almost never painful.
  • Ultrasound is widely available, easy-to-use and less expensive than other imaging methods.
  • Ultrasound imaging is extremely safe and does not use any ionizing radiation.
  • Ultrasound scanning gives a clear picture of soft tissues that do not show up well on x-ray images.

Bone Density

Bone densitometry uses a very small dose of ionizing radiation to produce pictures of the inside of the body (usually the lower spine and hips) to measure bone loss. It is commonly used to diagnose osteoporosis and to estimate an individual’s risk for developing fractures. It’s simple, quick and noninvasive. Additionally, it’s the most accurate method for diagnosing osteoporosis.

Benefits of a bone density test include:

  • DXA bone densitometry is a simple, quick and non-invasive procedure.
  • No anesthesia is required.
  • The amount of radiation used is extremely small—less than one-tenth the dose of a standard chest x-ray, and less than a day’s exposure to natural radiation.
  • Bone density testing is the most accurate method available for the diagnosis of osteoporosis and is also considered an accurate estimator of fracture risk.
  • The equipment is widely available making bone densitometry testing convenient for patients and physicians alike.
  • No radiation remains in a patient’s body after an x-ray examination.
  • X-rays usually have no side effects in the typical diagnostic range for this exam.


Screening tests may include laboratory tests to check blood and other fluids, genetic tests that look for inherited genetic markers linked to disease, and imaging tests that produce pictures of the inside of the body. These tests are typically available to the general population; however, an individual’s needs for a specific screening test are based on factors such as age, gender and family history. An EKG measures the electrical activity of the heart and reveals information on heart rate and rhythm.

The benefits on an EKG may include:

  • Cardiac CT for calcium scoring is a convenient and noninvasive way of evaluating whether you may be at increased risk for a heart attack.
  • The exam takes a small amount of time, causes no pain and does not require injection of contrast material.
  • No radiation remains in a patient’s body after a CT examination.
  • X-rays used in standard CT scans have no immediate side effects.

Staying healthy is one of the most important things that a person can do for themselves. Contact us to answer any questions or to schedule an appointment.

  1. I really like the idea of using vascular radiology to try to find a problem because, like you said, its a non-invasive way to look at things. My dad recently had to have lung surgery, and I’m glad they were able to use vascular radiology to be able to figure out the problem he was having. I’m really glad that there are ways that we can figure out health problems early, and without having to cut or stick anyone!
