Diagnostic Imaging

Bone Densitometry (DEXA)

Bone Densitometry is a form of x-ray technology known as dual-energy x-ray absorptiometry (DXA) and is commonly referred to as “DEXA”. DXA is a quick and painless procedure for measuring bone loss. Measurement of the spine and hip are most commonly done. Bone Densitometry is a widely used technique for measuring bone mineral density and diagnosing the presence of osteoporosis.

Osteoporosis can affect anyone, but is most common in post-menopausal women. Bone Densitometry is of limited use in people with spinal deformity or those who have had previous spinal surgery. It is also limited in patients who have had bilateral hip replacements. Osteoarthritis and vertebral compression fractures may also interfere with the accuracy of the test.

Common MRI Exams

MRI Abdomen

MRI’s of the abdomen are commonly performed to detect issues in the liver, gallbladder, digestive tract, and other organs. It can also be used to evaluate the state of blood vessels and organs prior to a surgery or transplant.

MRI Pelvis

MRI’s of the pelvis are commonly performed to detect issues in the bladder, prostate, reproductive organs, lymph nodes, rectum, anus and pelvic bones.

MRI Breast

MRI’s of the breast are many times administered after an initial mammogram to further explore abnormalities. Breast MRI’s are ideal for patients with “dense” breast tissue, because MRI images show more detail allowing radiologists to see more than with a standard x-ray image.

MR-Guided Biopsy

Using an MRI machine to guide a biopsy is very efficient because the clear images help radiologists to accurately sample the abnormality.

MRI Extremities

MRI is frequently used to scan major joints in the body. Including shoulders, wrists, knees and hips. MRI can locate and identify the cause of pain, swelling, and bleeding in the tissues around joints and bones. The images can see tears and injuries to tendons, ligaments and muscles. MRI can also show arthritis and tumors involving bones and joints.

MRI Spine

MRI is frequently used to determine the causes of back pain, leg pain and numbness. The exam can detect a bulging, degenerated or herniated intervertebral disk. MRI can be done to help plan surgeries of the spine. MRI performed after surgery will show whether infection or post-op scarring is present. Patients that have had surgery of the spine may require an injection of contrast material.

MRI Brain

MRI of the brain is useful in detecting brain tumors, strokes and certain disorders such as multiple sclerosis. MRI can also detect abnormalities of the eyes or inner ear. Most exams of the brain will require an injection of contrast material to enhance the visibility of certain tissues or blood vessels. A small needle is placed into a vein of the hand or arm for the injection.

Magnetic Resonance Angiography (MRA)

MRA provides detailed images of blood vessels with or without the use of contrast material. MRA can detect blocking or narrowing of arteries, and can also detect aneurysms, an enlarged artery. Commonly preformed MRA Exams include brain, carotids (neck) and renal arteries.

MR Enterography

Magnetic resonance (MR) enterography is used to diagnose inflammation, bleeding, obstructions and other problems in the small intestine. Patients ingest a barium contrast medium before their scan that highlights certain parts of the digestive tract in the images.

MRI Machine Types

3T High-Definition MRI

AMI is the only outpatient center in Lincoln equipped with the most advanced MRI that provides highly detailed images, faster. The large bore design is made for patient comfort and is ideal for and larger patients.

HERO 3T

Advanced Medical Imaging is the first location in the entire midwest to install a HERO 3T with the latest technology. Scan times are reduced by 50% using Air Recon DL.

1.5T Standard MRI

The most common of MRI machines is used the most often and has many benefits. There is more signal than the 1T open MRI providing a faster and better image. Less signal than the 3T MRI means less noise and heat than the stronger machine.

1T High-field Open MRI

The only high-field Open MRI in Lincoln, allows for three times the amount of patient space than cylindrical MRIs. The open design perfect for claustrophobic and bariatric patients.

Procedure Process

Wear loose, comfortable clothing. If you avoid clothing with metal zippers, belts or buttons made of metal you will not need to change. Otherwise, you may be asked to change into a gown or scrub pants. Private changing rooms and secured lockers are available. There are no restrictions on what you can eat before the exam.

The exam will last approximately 15-30 minutes. You will lie on your back or side on a padded table to allow for the examination of your spine and hips. Once in position, a detector moves slowly over the area to be imaged. While the exam is in progress, you will be asked to hold as still as possible to ensure a clear image. This process is completely painless.

The results of your bone density exam are interpreted by a radiologist and sent to your doctor and the patient portal. When they receive the results, they will discuss them with you and develop a treatment plan.
