WHAT IS NUCLEAR MEDICINE?
Nuclear Medicine is a method of imaging the body using radioactive materials.
Highly skilled professionals use special equipment and procedures to learn how
certain organs function and to diagnose and determine the extent of diseases.
The radioactive material is introduced into the body by injection, inhalation
or by swallowing. After the radiation has had time to travel to the body part of
interest, the imaging or scan begins.
WHAT CAN YOU EXPECT FROM YOUR NUCLEAR MEDICINE EXAMINATION?
The nuclear medicine technologist uses a special camera to detect the radiation
emitted from your body. A computer is used to help process the information and
to make the images easier to interpret.
The body part being scanned will be positioned close to the camera. You will
be asked to hold very still while the images are being made. There will be times
during the scan when the technologist will allow you to move and relax. It is
necessary to make several images in different positions to get a complete and
accurate study.
Upon completion of our routine views, the technologist will show your films
to the radiologist who is a doctor with special training in nuclear medicine.
At this time, the radiologist will review your study and may ask for extra views
or even x-rays to provide as much information as possible.
Be sure to tell us if you are pregnant.
The time that it takes to perform a nuclear medicine study varies. Some procedures
are more involved than others and naturally take longer to complete.
Please refer to the following list of scans for information about each individual
procedure.
BONE SCAN
Preparation: None.
Length of Study: Total body scan - approx. 3 1/2 - 4 hours
Limited scan - approx. 2 1/2 - 3 hours
Radioactive material is injected intravenously. There is a 2 hour wait after
the injections. You do not need to remain in our office during this wait. You
will need to drink at least 32 oz. of fluids within these two hours to aid in
absorption of the
injected radioactive material.
The actual scan time varies depending upon the area or areas of interest. A
total body bone scan will take approximately one hour to image the entire body.
Limited areas such as knees, shoulders, etc., take approximately 30 minutes
to scan.
THYROID SCAN
Preparation: Must be off of thyroid medication for at least
two weeks prior to scan. Should not have had any x-ray examinations using contrast
materials containing iodine for one month prior to scan.
Length of Study: Approximately 1 hour
Radioactive material is injected intravenously. Twenty minutes after
the injection, five views of the thyroid will be taken.
LIVER SCAN
Preparation: Abdomen should not have barium from x-ray studies,
otherwise no prep.
Length of Study: Approximately 1 hour
Radioactive material is injected intravenously. The scan will begin five minutes
after the injection. Nine different images are made of the liver and spleen.
KIDNEY SCAN (RENAL SCAN)
Preparation: None.
Length of Study: Approximately 1 hour
Radioactive material is injected intravenously and images are made during the
injection. There are two different methods used to scan the kidneys. One method
shows the anatomy (size, shape) of the kidneys and the other method is for kidney
function. With both studies, a radioactive material is injected and immediate
images are made. If only kidney anatomy is requested, there will be a one hour
delayed scan made after the initial injection films. When a kidney function
scan is requested by your doctor, you will be scanned continuously for 40 minutes.
GALLIUM SCAN (CHEST AND ABDOMEN)
CHEST
Preparation: None.
Length of Study: 30 minutes for three consecutive days.
Radioactive material is injected intravenously. Two images are made at 24,
48 and 72 hours.
ABDOMEN
Preparation: Liquid diet only for 72 hours prior to scan. Cleansing
enemas and laxatives each night before scan may be necessary.
Length of Study: 30-60 minutes for three consecutive days.
Radioactive material is injected intravenously. Two or four images are made
at 24, 48 and 72 hours. This will take approximately 1 hour each day.
HEPATOBILIARY SCAN
(LIVER, GALLBLADDER, COMMON BILE DUCT & SMALL BOWEL)
Preparation: No food or liquids for 8 hours before scan. Abdomen
should not have barium from x-ray studies.
Length of Study: At least 1 1/2 hours. Could take 6 1/2 hours
if delayed films are made.
Radioactive material is injected intravenously. After the injection, 2 images
are made at intervals of 5 minutes, 30 minutes and 60 minutes. These films are
then shown to the radiologist who will determine if delayed views are necessary.
SPECT Imaging
All of Wake Radiology Diagnostic Imaging's Nuclear Medicine departments are
fully SPECT (Single Proton Emission Computed Tomography) capable. Using SPECT,
we are able to provide 3-D computer reconstructed images of multiple views and
function of the organ being imaged, providing a much higher degree of resolution
and accuracy than with traditional planar imaging.
Please bring all insurance information to each visit. Most major insurers will
pay for radiology examinations, although some require prior authorization for
certain procedures. Patients may be required to pay at the time of service depending
on the type of insurance coverage. You should check your benefits with your
insurers at least a day before the exam.
Your insurance policy is a contract between you and your insurance company.
As a courtesy to you, we will be glad to file your insurance claims. Bring your
insurance card with you when you come for the exam. You will be responsible
for all services that are not covered by your insurance.
We participate with most health care plans. If you have any questions about
your coverage, you may call our business office at (919) 787-7411 or toll free
at 1-800-675-2232.
