Services: Imaging

Diagnostic imaging has made great strides since the discovery of x-rays more than a century ago. Today’s sophisticated, computer-aided imaging technologies allow physicians to diagnose and treat diseases more quickly and less invasively than ever before.

The Columbia Memorial Hospital Imaging Department, in partnership with Pacific Coast Imaging, provides a complete range of medical imaging procedures (see below). Our staff is highly trained and our facilities are certified by the U.S. Food and Drug Administration and American College of Radiology. Click here to visit the Pacific Coast Imaging website.

Prior to every exam, CMH Radiology Services patients are required to fill out a history form. Please note that the form is designed to protect your health and safety. It is very important to take time and think about the information you submit. You may download the form here prior to your exam.

It is important that your provider know what medications you are taking. Please click here and download a copy of our Medication Information Form. Fill it out and bring a copy with you when visiting any health care provider. It is a good idea to make copies of the completed form and carry one with you at all times.

Columbia Memorial Hospital Imaging Department offers many kinds of imaging


An ultrasound is the use of high-frequency sound waves to obtain images of the human body and visualize internal tissues and organs. Ultrasound is a useful way of examining many of the body’s internal organs, including, but not limited to, the heart, liver, kidneys and bladder.

Computed tomography (CT)

Columbia Memorial’s 32-slice CT scanners use a minimal amount of radiation and are fast and accurate. They provide thin image slices in high resolution, allowing for more accurate diagnosis. This technology makes results available to your doctor almost immediately. CT scans are generally performed to help diagnose the condition of organs and bony structures. Targeted CT scans are frequently used to diagnose various cancers, including lung, liver and pancreatic cancer. The exams also detect early heart disease.

Computed tomography angiography (CTA)

CTA is a high-quality, noninvasive diagnostic option that avoids the time, inconvenience and possible complications of an angiogram. The CTA almost always provides enough diagnostic information to avoid additional diagnostic tests. For the patient, there is decreased exam time (10 to 20 minutes total), no recovery time, less cost and a more accurate diagnosis.

Magnetic resonance imaging (MRI)

MRI is the imaging procedure of choice for most brain and spine conditions because of its superior contrast resolution and multiplanar capabilities. Columbia Memorial’s 1.5 Tesla MRI offers increased image quality, faster scanning time (20 minutes instead of 45 to 60 minutes) and increased patient comfort.

Digital radiography (DR)

Columbia Memorial is pleased to offer digital technology with digital radiography (DR) and computerized radiography (CR). Exams using DR take approximately half the time of conventional film radiography; a chest x-ray that used to take five minutes now takes about two minutes. Conventional spinal x-rays that can take 30 to 45 minutes are now done in 20 minutes using DR. Most importantly, DR reduces the need for repeats, which in turn reduces the possibility of unnecessary radiation exposure to patients.

Nuclear medicine

Nuclear medicine uses small amounts of radioactive materials to demonstrate both function and structure in nearly every major organ system. It is particularly good for diagnosing and staging many types of cancer and, increasingly, for the detection of cardiac disease. Nuclear medicine scans physiological functions of the body as opposed to structural imaging, which is performed with x-ray.

Women’s imaging

Columbia Memorial offers a complete range of mammography and ultrasound imaging. We recently added a state-of-the-art digital mammography system that has dramatically improved the quality and quantity of images we produce.

Bone densitometry

In a continuing effort to provide the best technology available, Columbia Memorial Hospital purchased a new Hologic bone densitometer. The bone densitometer evaluates the strength of your bones by measuring a small part of one or a few bones.


This is a noninvasive test that uses sound waves to produce a study of the motion of the heart’s chambers and valves and an assessment of blood flow. The echo sound waves create an image on the monitor as they pass over the heart. This is a noninvasive, highly accurate and quick assessment of the overall health of the heart. A cardiologist can quickly assess a patient’s heart valves and degree of heart muscle contraction. The images are displayed in real time on a video screen, and are recorded. No radiation is involved and the procedure can be performed on patients of all ages.
