CDP’s Radiology Services Further Explained

New Onsite Magnetic Resonance Imaging (MRI)

To better serve our patients, CDP now offers onsite MRI imaging services using the latest technology. MRI uses a powerful magnet, low-intensity radio waves, and computer technology to create multi-dimensional images of your body. MRI is most commonly used to look at muscles, nerves, and soft tissues in the body.

The new state-of-the-art MRI system at Coteau offers multiple patient-friendly features including quiet scanning and a wide 71 cm bore opening. These features create a safe and pleasant scanning environment, resulting in faster exams. Our new advanced MRI technology has the ability to consistently produce high-quality images of the brain, spine, knee and more.

If a provider orders an MRI, patients are encouraged to make the best, most convenient choice when it comes to scheduling their scan.

CT Scans

Computed tomography (CT) is a widely used diagnostic imaging modality. CT scans allow imaging of the internal anatomy in greater detail than general radiography. It produces multi-dimensional images that can be post-processed into 3D images. CT scans show several types of tissue – including lung, bone, soft tissue, and blood vessels with great detail allowing the radiologists to diagnose cancer, cardiovascular disease, infectious disease, trauma and musculoskeletal disorders.


Ultrasounds are a form of diagnostic testing that uses high-frequency sound waves to produce images of soft tissue and surrounding structures. Ultrasound is often used during pregnancy but has many other applications including visualization of abdominal and pelvic organs, veins and arteries, the heart and other tissues.

Bone Density Scanning (DEXA)

CDP offers bone density scans—also called dual energy X-ray absorptiometry (DEXA) scans. DEXA scans are used to measure bone mineral density or bone mass. These types of scans are helpful in diagnosing osteoporosis, a disorder characterized by bones becoming weak, fragile and brittle, increasing the risk for breaks and fractures.


Getting regular mammograms is the most effective way for women to monitor their breast health. This important screening uses low energy X-rays and takes multiple images of the breasts so radiologists can look for tissue abnormalities or lumps that may indicate the need for additional testing. Mammography breast imaging can detect cancer up to two years before lumps, or other symptoms, occur. And like all cancers, early detection is key to treating, and beating, breast cancer. The American Cancer Society recommends women start receiving regular mammograms at age 40. For those with a family history of breast cancer, talk to your primary care provider; you may need to start this important screening at a younger age. Don’t delay this critical screening that saves lives. One in eight women will have a breast cancer diagnosis in her lifetime. Routine mammography screenings are the best protection to find, treat—and beat—breast cancer.

Nuclear Medicine

Nuclear Medicine uses radioactive substances in the diagnosis and treatment of disease. Tests include:

  • Stress tests
  • Hepatobiliary (HIDA)
  • Bone
  • Thyroid
  • Lung perfusion scans

General Radiology

Radiography is a general imaging modality that can aid in a variety of diagnoses. Radiographs are a one-dimensional image that can show bone and internal organs. CDP utilizes the newest form of fixed and portable digital radiography equipment. Thus, in any situation, you’ll be provided with the highest quality exam.

Electrocardiogram (EKG), Holter & Event Monitors

EKGs, Holter, and Event Monitors allow CDP Health to record and monitor a patient’s heart rate. Electrocardiograms look at potential problems with the electrical activity of a patient’s heart. Holter and event monitors—or ambulatory electrocardiography devices—are often used to diagnose problems with a patient’s heart rhythm or rate, especially arrhythmias. These monitors are a portable form of testing used to look at the cardiovascular system’s electrical activity for an extended period of time.

Electroencephalogram (EEG)

EEGs are used to measure and record the electrical activity of the patient’s brain. This test tracks and reports the patterns of brainwaves. This test aids us in diagnosing seizure disorders, epilepsy, and other neurological disorders.
