A Safe, Comfortable Patient Experience

We invest in the latest imaging equipment because we put your comfort, safety and goals first. This advanced technology also means we can provide your doctor with clearer images, faster, allowing for sooner diagnosis and treatment. 


Our highly trained radiologists, technologists and patient care coordinators will walk you through your entire imaging appointment. We are also currently taking extra steps to ensure your safety and comfort:


  • You will check in on your phone from your car when you arrive for your appointment. A patient care coordinator will bring any necessary paperwork out to you. 
  • Our staff wears gloves and masks at all times. We will also use disinfectant wipes to open doors for and hand things to you, including any paperwork and insurance cards. 
  • All of our facilities are spacious enough to adhere to social distancing standards.  
  • The patient care coordinator will bring you inside when it is time for your appointment. A sanitized changing area, where you can store your items in a locker and change, if necessary, will be available to you.

Affordable, Accessible, and Worry-Free

Finally, given the financial concerns that often accompany health complications, we pledge to make your imaging as affordable as possible. Our exams cost up to 75% less than equivalent tests at hospitals, we accept most insurance plans, and we offer competitive self-pay rates.

At American Health Imaging, we know you have a choice in imaging providers. We hope to see you soon.

Services Offered

Magnetic resonance imaging (MRI) is a safe, pain-free imaging technique that combines magnets and radio waves to create detailed images of your body’s structures. While x-rays are typically used to view bones and joints, MRI is perfectly suited for organs, muscles and other soft tissues.

What to Expect During Your MRI

Typically lasting 30 to 60 minutes, MRI exams require very little preparation. Your technologist will simply ask you to remove jewelry, belts and other metal objects, and they will help you lie comfortably on a cushioned table. That table will then slide into the circular MRI machine, where you’ll remain for the duration of the exam. As the technologist collects images, they’ll be able to see, hear and speak to you, alleviating any concerns you may have.

Computed tomography (CT) uses a rotating series of x-rays to produce cross-sectional pictures of your body. These pictures appear as “slices” of a specific body part, and they show much more detail than traditional, flat x-rays.

Like MRI, CT is safe, painless and noninvasive. While MRI is most often used to examine muscles, organs and tumors, CT is generally applied to fractures, blood clots and abdominal injuries. In all cases, our skilled radiologists will consult with your doctor to determine which scan will deliver the most accurate and informative results.

What to Expect During Your CT Scan

Even faster than MRI, CT scans take just 15 to 30 minutes. You’ll set aside jewelry, belts and other metal objects, and depending upon the body part being scanned, you may be asked to remove your normal clothing and wear a hospital gown.

Some types of CT scans also require a contrast dye, which may be given as a flavorless drink or quick, painless injection. This dye appears bright white on your final images, helping doctors to differentiate between different types of tissue. If your CT scan does require a contrast dye, your doctor, radiologist or technologist may ask you to fast for a few hours before your exam.

Once you’re ready for the exam, you’ll simply lie on a cushioned table, which will slide your body into the circular CT machine. You’ll be able to communicate with your technologist throughout the exam, and they can help to alleviate any concerns you may have.

An arthrogram is a series of pictures that offers physicians a more detailed view than a single image. Typically used to examine shoulders, knees and other complex joints, arthrograms may be created from multiple x-rays, MRI images or CT images. Ultimately, this series of images helps doctors to find defects not only in bones, but in other joint structures such as tendons, ligaments, muscles and cartilage.

What to Expect During Your Arthrogram Exam

Most arthrograms require the use of an injectable contrast fluid, which helps to highlight a variety of joint structures. Injections may cause a slight burning sensation, but your technologist will use local anesthesia and a thin needle to minimize pain and soreness.

Once the dye is injected, you’ll be taken to an x-ray, MRI or CT machine for imaging, and the procedure should take one hour at most. Each of these imaging methods is safe, noninvasive and pain-free.

DTI, sometimes called DT-MRI, is short for Diffusion Tensor Magnetic Resonance Imaging. This innovative diagnostic technique is a variation of the standard brain MRI that is used to create high-resolution images of the anatomy of the brain. The DTI isolates water movement within the brain, which allows doctors to visualize regions that are not functioning properly. A traditional brain MRI scans cannot highlight these abnormalities, because they do not have the capability of tracking the normal patterns of water through the white matter of the brain. When that water flow is disrupted, DTI scans show the problem clearly. Tracking water diffusion allows doctors to see how the water normally flows through healthy parts of the brain’s axons and compare places where water diffusion is obstructed, signaling brain injury.

How does an DT-MRI work?

To have a DT-MRI, you lie on a cushioned table in front of a large tube containing a strong magnet. A coil will be used to help concentrate the magnetic field and radio waves to the head and neck. The result of the scan is a 3-dimensional digital image that a physician can review with you. The different amounts of realignment among atoms in different tissues allow us to visualize different types of tissue, such as muscle, fat, and bone, in your body. This can allow your doctor to detect unusual tissues, such as tumors, or damaged tissues, such as torn ligaments. American Health Imaging has invested in this technology that allows the (Tube) to have a largest wide bore and openings on both ends so you don’t feel like you’re going inside a tunnel. The most AHI centers this opening is 70 cm wide and only 125cm long so your head and feet are in the open on many exams. Claustrophobia is much less of a concern with the latest technology to obtain a high-resolution MRIs in a more open environment.

When should my doctor order an DT-MRI?

DT-MRI is utilized to help doctors determining the extent of a brain injuries (otherwise know at traumatic brain injury or concussions). Unlike traditional MRIs that use magnetic fields and computer technology to excite and then map the hydrogen atoms of the body, DTI machinery tracks the pathway of water throughout the brain. Because water in the brain only goes in one direction, it is easier to track this motion and thus map the different nerve paths of the brain as they are very complex. Many developmental, aging, and pathologic processes of the central nervous system are influenced these pathways of water in the brain. Once the nerve pathways are clearly mapped, neurologists can see if there is damage, bleeding or symptoms of other neurological or mental conditions.

Thanks to DTI, concussions are now being thoroughly imaged. Before the advanced technology of DTI MRIs, concussions could be examined through traditional MRIs but smaller amounts of bleeding and nerve damage were extremely difficult to determine. Now, doctors can track the nerve pathways in the brain with high clarity and understand the genetic and biological causes of some medical conditions.

DTI MRI has been instrumental in uncovering the area of the brain that possibly contributes to autism. Scientists have determined that Fragile X syndrome is the leading cause of mental developmental issues and the most frequent cause of autism spectrum disorders. Their conclusion found that FMRP (fragile X mental retardation protein) is critical in brain development and that if the correct positioning of brain cells during the development of the cortex is not made, autistic traits can emerge as a child becomes older. Read the full study These factors could not have been studied in such high detail without the help of DTI MRI imaging. The advanced technology of DTI MRI could be finding the causes and cures for more diseases and conditions in coming years.

How do I prepare for an DTI exam?

Minimal preparation is necessary for a DTI scan (also known as a DT-MRI). Because the MRI scanner is a giant magnet, we ask you to remove all metallic items from your body and pockets before approaching it. If you’re wearing anything that contains metal, including jewelry or sunglasses, you will need to remove those items. Braces and dental fillings typically won’t pose a problem, but pocketknives, pens, pins, and certain dental appliances can interfere in the test and cause problems with the MRI machine. The staff may ask you to wear a gown or clothing that do not contain metal fasteners. We also need to know if you have any metal in your body such as inner ear implants, vascular stents, brain aneurysm clips, a defibrillator / pacemakers, or an artificial joint. Next, you lie on a flat table that we slide into the tube to start the DT-MRI scan. We provide headphone and music to help you rel
