Radiology Services We Offer:

*New Service at Memorial: Minimally Invasive Stereotatic Breast Biopsy*


CT SCANS

CT stands for "computerized tomography" and it uses x-ray beams to look at internal body parts.

We operate a GE Light speed 16. The 16 refers to the number of "slices" of information captured with one revolution of the x-ray tube. The unit is excellent for evaluations of the head, chest and abdomen. We also perform CT angiography also known as CTA. In addition we offer CT guided interventional exams.

Depending on what organ system is being scanned, you may be required to consume oral contrast. Oral contrast is used to opacity the stomach, small bowel and colon. If you are scheduled for a CT and it requires oral contrast we ask that you drink one bottle before bed time the night before the test and the second bottle one hour before the test.

You may also have to receive intravenous contrast or IV contrast. IV contrast helps to provide contrast between the various soft tissues of the body to better allow for detection of abnormalities.

If receiving IV contrast you will be screened. We use an Iodine-based IV contrast and a small percentage of the population are allergic to or have an allergy to a related organic compound. If you believe you are allergic please notify your physician and the technologist performing your exam.

Prior to any x-ray exam, if there is a chance you could be pregnant, notify your technologist.

If your physician or provider has given you an order to have a CT performed, depending on what exam you are having we can offer same day appointments. In addition to our normal weekday hours, we can offer late evening and weekend appointments.

IV CONTRAST - RISKS & BENEFITS

Intravenous contrast helps to provide soft tissue contrast to detect abnormalities on a CT scan.

If your CT examination is ordered with intravenous contrast, please notify your physician and the technologist on site if you are allergic to iodine-based CT contrast, or have renal insufficiency as these may be contraindications to receiving intravenous contrast. Some contrast-allergies may be prevented with premedication beginning 1 day before. Ask your physician if your allergy qualifies for premedication.

A small percentage of people may experience an allergic reaction to IV contrast including itching, hives, or difficulty breathing. Please notify the technologist immediately if you feel any of these symptoms prior to leaving the facility.

MRI

MRI stands for magnetic resonance imaging. This technique of imaging uses magnetic fields to image parts of the body so as to allow physicians and doctors to make a precise and accurate diagnosis. We operate a GE 1.5 Tesla high-field strength MRI, which allows excellent evaluation of soft tissues. This magnet offers the largest bore available on the market, excluding research units. We provide imaging of the brain, spine, joints, bones, and abdomen. Unlike CT and Plain Films, MRI utilizes powerful magnetic fields to generate images, instead of x-rays. Because of this difference, you will be asked to fill out an MRI questionnaire prior to undergoing your MRI examination to ensure your safety. Please be sure to mention any metal, medicinal skin patches, or electronic devices your may have in or on your body.

WHAT PATIENTS MUST DO BEFORE GETTING AN MRI

Please be sure to mention any metal, aneurysm clips, stents, artificial heart valves, pacemakers, neurostimulator devices, medicinal skin patches, metallic fragments in your eyes, or tattoos, as these may be contraindications to having an MRI examination. Your device card or other documentation stating MRI compatibility must be provided prior to undergoing an MRI examination. This can be faxed prior to your exam or presented in person on the day of your exam. Please inform your physician of pregnancy, breastfeeding, anemia, asthma or allergic reactions to MR contrast agents. Please continue to take all your medications prior to the exam unless informed otherwise by a physician.

MR INTRAVENOUS CONTRAST

MR contrast is used to better delineate the soft tissues. The major risk of using contrast is an allergic reaction. If your MRI examination has been ordered with intravenous contrast, please be sure to notify your physician and the technologist on site if you have had a previous allergic reaction to MRI contrast, are currently pregnant or breast feeding, or have liver disease, kidney disease, diabetes, or hypertension, as these may be contraindications to receiving MRI contrast. If you are cleared to receive intravenous contrast, an IV will be placed prior to your exam.

MRI - WHAT TO DO IF YOU ARE CLAUSTROPHOBIC

If you experience claustrophobia, please notify your physician prior to your exam . If you take anti-anxiety medication for the exam, you must bring a driver with you.

Day of the exam:

Please arrive 30 minutes prior to the exam to fill out the MR questionnaire and to change clothes. You will have to remove all metallic objects including glasses, keys, cell phones, wallet, and belt prior to the exam.

The exam will last between 30-60 minutes.

You will be positioned on the gantry table and guided into the doughnut hole. If contrast is used, an IV will be placed in your arm prior to the exam.

During the exam, it is important to remain as still as possible throughout the exam to get the most optimal exam. Knocking sounds will be heard during the exam which arises from the magnets working. You will be provided ear plugs to minimize these noises.

PLAIN FILM

We are able to offer x-rays of any body part. Plain x-rays are performed on a walk in basis.

STEREOTACTIC BREAST BIOPSY

A small probe is inserted into the breast through a tiny incision. The special needle used gently draws, cuts and collects tissue samples.    Stereotactic Breast Biopsy Patient Video

Advantages to this breast biopsy procedure:
- Simple, safe and painless
- Local anesthesia only
- Procedure takes less than an hour in a comfortable outpatient setting
- No stitches are needed
- Several samples can be taken without removing and reinserting the needle
- A tiny Tissue Marker can be placed in the breast, at the location of the biopsied tissue, for future follow-up
- Highly accurate diagnosis

Why do I need a breast biopsy?
Your recent mammogram may show an abnormality or tiny calcium deposits, called microcalcifications in your breast. Only a biopsy can determine if that abnormality is cancerous or benign (noncancerous).

What is Stereotactic Breast Biopsy? Stereotactic biopsy is a diagnostic tool. It is a non-surgical way to obtain the tissue sample needed to make a conclusive diagnosis. The procedure is state-of-the-art and provides early, accurate results. Two digital x-ray images of breast tissue are taken at different angles. A computer uses the images to locate the abnormality and calculate precise coordinates. Then the computer guides the physician in placing the needle at the correct target site.

How is this different than other biopsy procedures? This procedure is less invasive and less painful compared to other methods. It takes far less time to perform this nonsurgical technique and you'll be back home the same day.

Will I be awake or asleep? You will be awake for this type of procedure. A local anesthetic will be used to numb only the breast area where the biopsy will occur.

How long does the procedure take? Biopsy times vary. Typically, it should take a total of 60 minutes from the time you enter the exam room to the time you leave. The actual biopsy procedure will take a very short time. After the biopsy, a final set of images may be taken and your physician may place a marker at the biopsy site for future reference to identify the exact location of the biopsy. The marker is made of titanium and poses no health or safety risk. You will not be able to feel or notice the marker after placement.

Is this procedure painful? You might feel a slight sting or pinch when the numbing medication is being inserted into the breast. Numbing the breast prior to the biopsy causes the rest of the procedure to be pain free.

Will I have a scar? Most women do not experience any permanent scarring.

Are there any side-effects? The treatment is generally free of side effects. In some cases, "black and blue" discolorations may occur in the region of the biopsy. Every such operation involves a minimal risk of infection.

ULTRASOUND SERVICES

Ultrasound utilizes sound waves to generate images and provides excellent contrast between soft tissue structures in the body. Ultrasound is used for imaging the solid abdominal and pelvic organs, arteries and veins of the extremities, thyroid, and other superficial parts of the body. Because ultrasound does not use x-rays or intravenous contrast agents, it is safe in pregnancy.

On the Day of your Ultrasound Examination:

If an ultrasound examination of your abdomen has been ordered, we ask that you abstain from eating or drinking 4 hours prior to your exam. All other ultrasound examinations do not require fasting.

Please arrive 30 minutes prior to your exam time to complete paperwork and to change clothes.

At the time of your exam, the technologist will bring you to the ultrasound room where you will lie on the exam table. The technologist will place warm gel on your skin and use an ultrasound probe to scan over the examination areas. You will be given a clean towel to clean the gel from your skin prior to leaving.

In addition to our normal weekday hours, we can offer late evening and weekend appointments. To schedule an appointment please call 903.438.4543.
