Patient Education

New & Improved MRI Experience

Advanced Motion Correction Technology
With this new MRI technology (Signa Explorer Lift) comes faster and more efficient studies, enhanced imagery, and drastic sound reduction. This cutting-edge technology ensures that image quality doesn’t suffer when a patient moves or breathes during the scan. Previously, the slightest movement resulted in repeat scans and low-quality images. Now, patients can be confident that they won’t have to endure multiple retakes—resulting in less time spent in a confined space.

Scan time decreased by up to 40%.
Scans are significantly quieter to increase patient comfort. Our revolutionary technology shatters industry norms to reduce noise like never before—reducing it to less than 3 decibels above ambient. We also provide headphones for patients to listen to their preferred music or podcasts.
We lowered our charges, which gave us a competitive edge against freestanding imaging centers. Plus, you won’t receive separate bills from radiologists because our fees include the radiologist interpretation for MRIs.
Image Resolution will increase dramatically—providing superior quality for both our Radiologists and ordering Physicians.
Advanced imaging gives us the ability to offer more detailed vascular studies.
Improved SNR (Signal to Noise Ratio)
Metal suppression technology (eliminates artifact from metal)
Evening and weekend availability

Sedated MRI

We can perform a general Sedation MRI for any region of the body. We administer the sedation medication through an IV or a mask, so no breathing tube or other assisted ventilation is required. We monitor each patient with an oximeter, a blood pressure cuff, or an EKG—under the supervision of a trained anesthesiologist. We also offer oral sedation for patients who prefer that option.

We typically recommend MRI sedation for patients who are extremely anxious, claustrophobic, or have medical conditions that make it either difficult or impossible to remain motionless duration the exam. MRI sedation also might be a good option for young children and adolescents who are incapable of remaining motionless the whole time or might struggle to understand directions.

Radiological advantages of anesthetized MRI:

Extremely accurate imaging
Improved patient experience and compliance
Minimized time in MRI suite
Constant and direct care by MMH anesthesiologist and radiology staff

CT Scan

A CT scan—also known as a CAT scan or Computed Tomography scan—is an imaging test that details the inside of the body. A CT scan uses X-rays and a computer to create pictures of your organs, bones, and other tissues. CT scans show more detail than a generic X-ray. The procedure can be done on any body part, and it’s easy and painless.

CT Scan with Contrast

In a CT scan, dense substances—like bones—are easy to see. However, things like soft tissue doesn’t show up as well and might appear faint in the image. To help the images appear more clearly, we might use a special dye called a contrast material. The contrast material blocks the X-rays and appears white in the scan. It highlights blood vessels, organs, and other less dense structures.

Contrast materials usually are made of iodine or barium sulfate. You might receive these drugs in one or more of the following three ways:

  • Injection: The drugs are injected directly into a vein to help your blood vessels, urinary tract, liver, or gallbladder stand out in the image.
  • Orally: Drinking a liquid with the contrast material can enhance scans of your digestive tract.
  • Enema: If your intestines are being scanned, the contrast material can be inserted in your rectum.

After the CT scan, drink plenty of fluids to help your kidneys remove the contrast material from your body.

How CT Scans Work

A CT scan uses a narrow X-ray beam that circles around one part of your body—providing a series of images from various angles. A computer uses this information to create a cross-sectional picture. This two-dimensional (2D) scan shows an image of the inside of your body.

This process is repeated to produce multiple images. The computer stacks these scans on top of each other to create a three-dimensional (3D) image. From here, your doctor has a better view of your organs, bones, or blood vessels.
A radiology technologist performs the CT scan. During the test, you’ll lie on a table inside a large, round CT machine. As the table slowly moves through the scanner, the X-rays rotate around your body. It’s normal to hear a whirring or buzzing noise. Since movement can blur the image, we’ll ask you to stay very still.

The length of scan time depends on what body parts are being scanned. The process can take anywhere from a few minutes to 30 minutes.

Ultrasound scans use high-frequency sound waves to create an image of a patient’s internal body structures. Doctors commonly use ultrasound scans to study a developing fetus, a patient’s abdominal and pelvic organs, muscles and tendons, or heart and blood vessels. Ultrasound scans are sometimes referred to as a Sonogram or Sonography.

The Ultrasound machine directs high-frequency sound waves at the internal body structures being examined. The reflected sounds or echoes are recorded to create an image you can view on a monitor. The machine emits and receives sound waves from a small, hand-held probe called a transducer.

While an Ultrasound scan is typically non-invasive, some scans are done with a special probe that’s inserted into the body (for some obstetric, pelvic examinations, or prostate examinations). Sometimes radiologists use Ultrasound scanning to guide them during invasive procedures.

Methodist McKinney Hospital offers the following types of Ultrasound scans

Abdominal scans: Might be used to investigate abdominal pain, nausea, vomiting, and lumps. Structures such as the gallbladder, bile ducts, liver, pancreas, spleen, and kidneys might be examined.
Pelvic scans: Might be performed if a woman is suffering from pelvic pain, has abnormal periods, fibroids, cysts, or other conditions associated with the female reproductive system.
Other uses: Might include musculoskeletal scans (to check regions like a shoulder, hip, or elbow) or breast scans. A special type of Ultrasound scan, called a Doppler Ultrasound, detect the speed and direction of blood flow in certain regions of the body.

Special Instructions

Some Ultrasound examinations require special preparation beforehand, such as:

  • You might be asked not to eat for six hours before an abdominal scan.
  • Some pelvic examinations require a full bladder before scanning.

Ask your doctor or the Ultrasound technologist if you need to complete any special preparation before your scan.


X-rays are a form of radiation that utilizes electromagnetic waves. X-rays create pictures of the inside of your body. The images show the parts of your body in different shades of black and white. This happens because different tissues attenuate different amounts of radiation. Bones look white because bone Calcium absorbs X-rays the most. Fat and other soft tissues look gray because they absorb less of the X-ray. Lungs look black because air absorbs X-rays the least.

X-rays are most commonly used for identifying broken bones. X-rays are used in other ways, too. For example, chest X-rays can spot pneumonia, and mammograms use X-rays to identify breast cancer.
It’s common for a patient to wear a lead shield when undergoing an X-ray to protect certain parts of the body. X-rays emit small amounts of radiation. For example, a chest X-ray produces an amount of radiation that’s similar to the amount you’re naturally exposed to from the environment over a ten-day period.

Myelography is an imaging examination that uses fluoroscopy—a type of X-ray—to insert a spinal needle into the spinal canal and inject contrast material into the area surrounding the spinal cord and nerve roots.

When the contrast material enters the subarachnoid space, the radiologist can view and evaluate the status of the spinal cord, nerve roots, and meninges. Myelography provides a detailed image (myelogram) of the spinal cord, nerve roots, subarachnoid space, and spinal column. The radiologist uses fluoroscopy to view the contrast material as it passes through the subarachnoid area. The radiologist also takes permanent images of the contrast material surrounding the spinal cord and nerve roots to document any abnormalities. In many cases, the radiologist might supplement the myelogram with a Computed Tomography (CT) scan to get a better look at a patient’s anatomy and any abnormalities present.

How to Prepare

Inform your physician of any medications being taken and any allergies—especially if allergic to iodinate contrast materials. Additionally, inform your doctor about any recent illnesses or other medical conditions. Specifically, the physician needs to know if (1) you take medications that you should stop taking a few days before your procedure and (2) whether you have a history of reacting poorly to the contrast material.

Some drugs—including antipsychotic medications, antidepressants, and blood thinners—shouldn’t be taken one or two days before undergoing a Myelography study. The most important type of medication that a patient should stop taking prior to a study is blood thinners (anticoagulants). If you take blood thinners, contact your physician about alternative methods of maintaining anticoagulation while you undergo a Myelogram.

When you come in for a myelography study, you will need to remove some of your clothes and will receive a gown to wear during the exam. You also might need to remove jewelry, removable dental appliances, eyeglasses, and any metal objects or clothing that might interfere with X-ray images.

When the Myelogram is complete, patients usually remain in the ER for an observation period of two to three hours before being discharged. With this in mind, you should arrange to have a relative or friend take you home afterward.


An arthrogram is an X-ray that views bone structures after contrast fluid is injected into a joint area. When contrast fluid leaks where it doesn’t belong, disease or injury is possible—as a leak might indicate a tear, opening, or blockage.
During the procedure, a radiologist injects the contrast fluid into the joint using fluoroscopy to guide the injection needle into the correct position.

Once the injection is finished, the radiologist uses a Magnetic Resonance Imaging (MRI) or Computed Tomography (CT) scan to take images of the joint area. While an MRI or CT scan provides some information about soft tissue structures, an arthrogram can provide much more detailed information about what’s wrong within the joint.

How to Prepare

No specific preparation is required.

If you have received a generic X-ray, CT scan, or MRI of the joint at another facility, bring those scans to your arthrogram appointment at Methodist McKinney Hospital.

Remember to wear comfortable clothing to your scheduled appointment to allow for easy access to the joint being examined.
