How do imaging tests help maintain and diagnose your health?

The quality of your exam and results are used by your doctor to diagnose your health, develop a course of treatment, if needed, and monitor your progress with treatment.

Who will perform your imaging tests?

All imaging testing at Longmont United Hospital is performed by registered and highly qualified personnel. These are the same technologists that perform your imaging exams when you are in the hospital.

CT: Computed Tomography (64 slice)

Computed Tomography is a scan of x-rays that produces detailed images of organs, bones, soft tissues and blood vessels. During the process, the CT rotates around your body taking images (slices) of the body. Small amounts of radiation are used. You will need an order from your physician for any CT exam.

Digital Radiography

Digital Radiography is a digital x-ray image that is available to the physicians on the computer.


Fluoroscopy captures "live" moving images of moving body structures, similar to an x-ray video camera.

Interventional Radiology

The Interventional Radiology process is when image guidance is used during minimally invasive procedures. Interventional Radiology is used for both diagnostic and treatment purposes.

 +   Mammography
MRI: Magnetic Resonance Imaging

Magnetic Resonance Imaging provides high-resolution images of internal organs and tissues.

Nuclear Medicine

Nuclear Medicine is different from x-ray, ultrasound, and other diagnostic images in that it helps find disease in the body by viewing images that show structural change. Patients are given a radioactive material through injection, swallowing, or inhalation then an image is taken of the organ, bone or tissue in question.

Ultrasound Imaging

Ultrasound exams produce live images that show movement and structure of internal organs. The process uses high frequency sound waves instead of ionizing radiation.

Do I check in at registration every time I come for an imaging test?

Each time you come in for testing your insurance company sees it as an individual visit which requires you to check in at registration. Registration will verify a new account number, insurance, and consent for treatment. Some of the imaging tests require “pre-authorization” from your insurance company prior to the test being done.

May I take my medications before my imaging procedure?

Can I get a copy of my results?

You will need to fill out an Authorization to Release Protected Health Information and have identification available to give the Imaging file room or Medical Records Department. This gives us legal permission to give you a copy of your images and results. View HIPAA Statement
