Preparing for a Procedure

Your physician has scheduled you for a test in Putnam Hospital Center's Radiology Department. Choose the test you are scheduled for below for more information and to find out how to prepare for your procedure.

I am scheduled for:

CT Scan Procedures
A Computed Axial Tomography Scan (CT Scan) is a diagnostic test that combines the use of x-rays with computer technology. Contrast agents improve the accuracy of the exam. In preparation for your examination, you may be asked to drink oral contrast and/or receive intravenous contrast. If oral contrast is required, it must be administered at least 90 minutes prior to the examination.
Certain patients are at higher risk for experiencing reactions to intravenous (IV) contrast material. These include patients who have had previous reactions to contrast material or any other drug, as well as patients who have hay fever, allergies, asthma, emphysema, kidney disease, multiple myeloma, diabetes, or heart disease. If you have any of these conditions, please inform the technologist or radiologist that is performing your examination.
If you have had a CT scan at an outside facility previous to this Putnam Hospital Center exam, please bring your films with you at the time of your appointment.
If you are or think you may be pregnant, please notify the technologist.

Adults & Children Over 3 Years of Age :

  • Head Scan, Chest Scan, Abdomen Scan (without Pelvis Scan),

An intravenous pyelogram (IVP) is an x-ray procedure which provides detailed pictures of the urinary tract. The test requires injection of a contrast agent, which circulates through the body and highlights the kidneys, ureters, and bladder.
Certain patients are at higher risk for experiencing reactions to intravenous (IV) contrast material. These include patients who have had previous reactions to contrast material or any other drug, as well as patients who have hay fever, allergies, asthma, emphysema, kidney disease, multiple myeloma, diabetes, or heart disease. If you have any of these conditions, please inform the technologist or radiologist that is performing your examination.
If you are or think you may be pregnant, please notify the technologist.

Mammography
A mammogram is a set of x-ray images of the breasts. Mammography is the most effective means of detecting breast cancer at its earliest, most treatable stage. A technologist will carefully position you for the examination. Some pressure will be applied to compress the breast tissue to help see any abnormal areas. At least two x-rays of each breast are required for a thorough exam. The mammography service is accredited by the American College of Radiology (ACR).

If you have had a mammogram at an outside facility previous to this Putnam Hospital Center exam, please bring those films with you at the time of your appointment.

You will receive a letter notifying you of your results within 7 to 10 days after your mammogram.

If you are or think you may be pregnant, please notify the technologist.

Preparing for your mammography

  • No powders, cream, or deodorant on or around the breast or armpit area prior to the exam.
  • Do not place any patches (i.e., estrogen, nitroglycerin) on the chest or breast area prior to the exam.

Please register in the main lobby of the hospital and bring your insurance card and MD order (script) at the time of your examination. Thank you.

Magnetic Resonance Imaging (MRI)
Magnetic Resonance Imaging (MRI) produces images of internal organs and structures not obtainable by any other method. No x-ray radiation is used. MRI uses a magnetic field, radio waves, and a computer to produce its images. In some situations, you may receive an intravenous contrast agent to improve the accuracy of the exam. Our MRI facility has been accredited by the American College of Radiology (ACR).

MRI is very safe but precautions are necessary to prevent accidents or complications. Certain metals and electrical equipment are not allowed near the scanner. Patients with pacemakers or other implanted metallic devices may not be able to be scanned. For safety purposes, MRI staff screens patients prior to their appointment and at the time of their MRI.

If you have, or suspect you have any of the following implants, please speak with the technologist prior to your examination:

  • Metal Chips in Eyes Infusion pump
    (insulin, chemo, medication, etc.)
  • Aneurysm clip (brain) Pacemaker
  • Cochlear or stapes
  • Implants (ears) Neurostimulator
    (lower back)
  • Breast implants
  • Lens implants (eyes) Rods (Harrington)
  • Joint replacements Hearing aids
  • Medication patches
    (i.e. nitro) I.U.D. or pessary
  • Hickman/Broviac catheters, Metal screws, pins, shrapnel
  • Denture/dental appliances

Additional questions MRI staff will ask you prior to your exam:
Have you taken any medication to sedate or relax you prior to your MRI exam? If yes, what medication and dosage?

If you require sedation for your MRI, please make arrangements prior to your appointment to have transportation home.

If you are or think you may be pregnant, please notify the technologist.

Please bring your insurance card and MD order (script) at the time of your examination.

Ultrasound Procedures
An ultrasound examination is a diagnostic procedure that uses sound waves to produce pictures of the inside of the body. No radiation is used for these exams. The pictures are produced painlessly by a technologist or radiologist sliding a probe over the skin. A computer creates the images as it measures the high frequency sound waves bouncing off the internal structures of the body.
Adults:

  • Abdominal Ultrasound:Nothing to eat or drink after midnight or at least 8 hours before exam.
  • Pelvis or Bladder Ultrasound: Day of exam: Full bladder is necessary. Empty bladder 2 hours before exam and then drink 24-36 oz. of water within 30 minutes. Do not urinate again until exam has been completed.
  • Transrectal Ultrasound: Fleet enema (available at any pharmacy) 1-2 hours before scheduled exam.
  • Transvaginal Ultrasound: No preparation. (Not recommended if patient is having a heavy menstrual flow.)
  • OB Ultrasound: See prep for Pelvis/Bladder Ultrasound
  • Renal Ultrasound: Do not eat 4 hours before your exam. Drink plenty of water only, you may void.
  • Biopsy with Ultrasound Guidance: Follow physician's instructions.

Children: Same as above if older than 12 years.

  • If 3-12 years old, same as above, but need drink only 10-20 oz. prior to pelvic or bladder ultrasound.
  • If younger than 3 years old, contact your referring physician or our office for instructions.
  • Please bring your insurance card and MD order (script), at the time of your examination.
    Where to Go:

Park in the front enclosed parking lot (if you are handicapped, you may park in front in the designated spots). Enter through the hospital's main entrance, proceed past the gift shop to the registration area where you will be directed to the correct area of radiology after registering.

Upper Gastrointestinal (GI) Procedures
Barium Enema Procedures
GI Series and/or Small Bowel Series

The digestive tract is studied with x-ray pictures following ingestion of barium to coat the lining of the throat, esophagus, stomach, and small bowel, making it visible to the x-ray beam.

top

 

Barium Enema Procedures (Barium Enema or Air Contrast Barium Enema*): Barium Enema Prep: The large bowel (colon and rectum) is examined by administering barium (and sometimes air) through a rectal tube to coat the lining of the bowel, making it visible to the x-ray beam.
For the exam to be most accurate, it is important that the colon be thoroughly cleansed so that stool will not be confused for a tumor.
If you are or think you may be pregnant, please notify the technologist.

Adults: **Requires 24 hour prep: Drink clear liquids only (no food) 24 hours prior to exam**

  • Purchase two (2) bottles of Fleet Phosph-Soda, buffered saline laxative at any pharmacy.
  • Night before exam: 7:00 PM: add all contents of one of the 1 ½ ounce bottles to one half glass of water and drink; this can be followed by a glass of clear fruit juice. Drink at least three (3) 8 ounce glasses of clear liquid before retiring... more is permitted.
  • Morning of exam: 6:00 AM Add 1 ½ ounce bottle of the phospho-soda to one half glass of water and drink. This may be followed by one 8 ounce glass of clear fruit juice.

Children:
For pediatric patients, check with the Radiology Department at (845) 279-5711 ext. 2428 or 2429
*If Bowel Obstruction or Ulcerative Colitis is suspected, the referring physician should consult with the radiologist prior to administration of bowel prep.
.
Please bring your insurance card and MD order (script), if applicable, at the time of your examination.
