Imaging It's #WHOWEARE
The Most Common Imaging Procedures We Perform Are:
Magnetic Resonance Imaging (MRI) is a test that uses powerful magnets, radio waves, and a computer to make detailed pictures of the inside of your body. Unlike X-rays and Computed Tomography (CT) scans, an MRI doesn’t use radiation.
An MRI helps a doctor diagnose a disease or injury, and it can monitor how well you’re doing with a treatment. MRIs can be done on different parts of your body.
Before you get an MRI, here are some things to tell your doctor prior to your scan:
- If you have any health problems, such as kidney or liver disease
- Recently had surgery
- Have any allergies to food or medicine, or if you have asthma.
- Are pregnant or might be pregnant
No metal will be allowed in the MRI suite. Notify your doctor or MRI tech if you have any of these devices present in your body:
- Artificial heart valves
- Body piercings
- Cochlear implants
- Drug pumps
- Fillings and other dental work
- Implanted nerve stimulator
- Insulin pump
- Metal fragments, such as a bullet or shrapnel
- Metal joints or limbs
- Pacemaker implantable cardioverter-defibrillator (ICD)
- Pins or screws
On the day of the test, wear loose, comfortable clothing that doesn’t have snaps or other metal fasteners. You will be able to wear your clothes for the exam if this is done. If not, you’ll have to change into a gown.
Remove all of these before you go into the MRI room:
- Cell phone
- Hearing aids
- Underwire bra
If you don’t like enclosed spaces or you’re nervous about the test, tell your doctor. We also offer Sedation MRIs.
A specially trained doctor called a radiologist will read the results of your MRI and send the report to your doctor.
Your doctor will explain the meaning of your test results and what to do next.
A CT scan, also known as a CAT scan or Computed Tomography scan, is an imaging test that details the inside of the body. Contrast dye may be used to help visualize some abnormalities.
A CT scan uses a combination of X-rays and a computer to create pictures of your organs, bones and other tissues. It shows more detail than a regular X-ray. You can get a CT scan on any part of your body. The procedure doesn’t take very long, and it’s painless.
How CT Scans Work
A CT scan use a narrow X-ray beam that circles around one part of your body. This provides a series of images from many different angles. A computer uses this information to create a cross-sectional picture. Like one piece in a loaf of bread, this two-dimensional (2D) scan shows a “slice” of the inside of your body.
This process is repeated to produce a number of slices. The computer stacks these scans one on top of the other to create a three-dimensional (3D) image. This can give your doctor a better view of your organs, bones, or blood vessels.
A radiology technologist will perform the CT scan. During the test, you’ll lie on a table inside a large, doughnut-shaped 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. Movement can blur the image, so you’ll be asked to stay very still. You may need to hold your breath at times.
How long the scan takes will depend on what parts of your body are being scanned. It can take anywhere from a few minutes to a half-hour.
CT Scan with Contrast
In a CT scan, dense substances like bones are easy to see. But soft tissues don’t show up as well. They may look faint in the image. To help them appear clearly, you may need a special dye called a contrast material. They block the X-rays and appear white on the scan, highlighting blood vessels, organs, or other structures.
Contrast materials are usually made of iodine or barium sulfate. You might receive these drugs in one or more of three ways:
- Injection: The drugs are injected directly into a vein. This is done 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, the pathway of food through your body.
- Enema: If your intestines are being scanned, the contrast material can be inserted in your rectum.
After the CT scan, you’ll need to drink plenty of fluids to help your kidneys remove the contrast material from your body.
Ultrasound scans use high-frequency sound waves to make an image of a person’s internal body structures. Doctors commonly use ultrasound to study a developing fetus (unborn baby), a person’s abdominal and pelvic organs, muscles and tendons, or their heart and blood vessels. Other names for an Ultrasound scan include 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 that can be seen on a monitor. The sound waves are emitted and received from a small, hand-held probe, called a transducer. The high frequency of sound means the human ear cannot hear it.
An Ultrasound scan is usually non-invasive (done from outside the body). However, some scans are done with a special probe that is inserted into the person’s body (for some obstetric, pelvic examinations or prostate examinations). Sometimes radiologists will use Ultrasound scanning to monitor and guide during invasive procedures.
Methodist McKinney Hospital offers many types of Ultrasound scans:
- Abdominal scans – may be used to investigate abdominal pain, nausea, vomiting, and lumps. Structures to be examined may include the gallbladder, bile ducts, liver, pancreas, spleen, and kidneys.
- Pelvic scans – may 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 – May include musculoskeletal scans (to check regions like a shoulder, hip or elbow) or breast scans (for example, to further investigate an abnormality picked up by physical examination or mammogram). A special type of Ultrasound scan, called a Doppler Ultrasound, is used to detect the speed and direction of blood flow in certain regions of the body, for example, neck and extremity vasculature.
Some Ultrasound examinations require special preparation beforehand, such as:
- You may be asked not to eat for 6 hours before an abdominal scan.
- Some pelvic examinations require you to have a full bladder before the scan.
You will need to ask your doctor or the Ultrasound technologist if you need to do any special preparation before your scan.
X-rays are radiation that utilize 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 is because different tissues attenuate different amounts of radiation. Calcium in bones absorbs X-rays the most, so bones look white. Fat and other soft tissues absorb less, and look gray. Air absorbs the least, so lungs look black.
The most familiar use of X-rays is checking for broken bones, but X-rays are also used in other ways. For example, chest X-rays can spot pneumonia. Mammograms use X-rays to look for breast cancer.
When you have an X-ray, you may wear a lead shield to protect certain parts of your body (If not in the area of interest). The amount of radiation you get from an X-ray is small. For example, a chest X-ray gives out a radiation dose similar to the amount of radiation you’re naturally exposed to from the environment over 10 days.
Special Radiology Procedures (Myelograms, Barium Studies, etc.)
Myelography is an imaging examination that involves the introduction of a spinal needle into the spinal canal and the injection of contrast material in the space around the spinal cord and nerve roots (the subarachnoid space) using a real-time form of X-ray called Fluoroscopy.
When the contrast material is injected into the subarachnoid space, the radiologist is able to view and evaluate the status of the spinal cord, the nerve roots, and the meninges. Myelography provides a very detailed picture (myelogram) of the spinal cord, nerve roots, subarachnoid space, and spinal column. The radiologist views the passage of contrast material in real-time within the subarachnoid space as it is flowing using fluoroscopy but also takes permanent images of the contrast material around the spinal cord and nerve roots in order to document abnormalities. In many of these cases, the myelogram may be followed by a Computed Tomography (CT) scan to better define the anatomy and any abnormalities.
How to Prepare
You should inform your physician of any medications being taken and if there are any allergies, especially to iodinate contrast materials. Also, inform your doctor about recent illnesses or other medical conditions. Specifically, the physician needs to know if (1) you are taking medications that need to be stopped a few days before the procedure and (2) whether you have a history of reaction to the contrast material used for the myelogram.
Some drugs should be stopped one or two days before a Myelography study. These include certain antipsychotic medications, antidepressants, blood thinners, and some other drugs. The most important type of medication that must be stopped is blood thinners (anticoagulants). If you are taking blood thinners, you should speak with your physician about alternative methods of maintaining anticoagulation while you are undergoing a Myelogram.
You will be asked to remove some of your clothes and will be given a gown to wear during the exam. You may also be asked to remove jewelry, removable dental appliances, eyeglasses and any metal objects or clothing that might interfere with the X-ray images.
At the conclusion of the Myelogram, the patient usually remains in the ER for an observation period of about two-three hours and is then discharged. You should arrange to have a relative or friend take you home.
An X-ray to view bone structures following an injection of a contrast fluid into a joint area. When the fluid leaks into an area that it does not belong, disease or injury may be considered, as a leak would provide evidence of a tear, opening, or blockage.
A radiologist, a physician specialized in radiology, injects the contrast medium into the joint using Fluoroscopy to help guide the injection needle into the correct position.
Once the injection is finished, images of the joint are taken using Magnetic Resonance Imaging (MRI) or Computed Tomography (CT) scan. While a plain MRI or CT can provide some information of the soft tissue structures, an arthrogram can sometimes provide much more detailed information about what is wrong within the joint.
How to prepare:
No specific preparation is usually required.
If you have already had a plain X-ray, CT or MRI of the joint to assess any pain or other symptoms at another facility other than Methodist McKinney Hospital, you will need to bring these scans to your Arthrogram appointment.
It may be best to wear comfortable clothing with easy access to the joint being examined.
