Nuclear
Medicines in India
Nuclear medicine is now commonplace. As it involves use of radioactive
isotopes in very small doses in diagnosing and treatment of diseases,
radioactive medicine injected or administered orally and the distribution
in the organ is scanned using a Gamma camera. Tariffs are low
starting from US$ 95 for Thallium rest (SPECT), US$ 43 for lung perfusion
and venogram of upper or lower limbs, US$ 335 for Ventilation study, US$
40 for a whole body skeletal study and US4 20 for Tc-99m Thyroid scan.
Various non-cardiac planar / SPECT studies for bone, thyroid, liver and
lungs scanning functions are performed at specialized centers in India.
Diagnostic imaging of the brain, stomach, kidneys, heart, adrenal glands
as well as sites of occult infection with the help of sophisticated Gamma
Camera with tomographic facilities linked to computer systems can also
be performed at many of these centers.
Department of Nuclear - Medicine at Manipal Hospital,
Bangalore is equipped with the latest gamma camera assisted by an ultra-sensitive
fast computer and is managed by highly trained & competent medical
and technical experts. Our procedures commonly called (Scintigraphic investigations
or scan) provide valuable functional-information (to a certain extent
structural information as well) that can enable physicians / surgeons
to make an early diagnosis. These tests are relatively safe, painless
and are considered to be among the safest diagnostic tests available.

Nuclear Medicine
Nuclear medicine began approximately 50 years ago and has evolved into
a major medical specialty for both diagnosis and therapy of serious disease.
More than 3,900 hospital-based nuclear medicine departments in the United
States perform over 10 million nuclear medicine imaging and therapeutic
procedures each year. Despite its integral role in patient care, nuclear
medicine is still often confused with other imaging procedures, including
general radiology, CT, and MRI.
Nuclear medicine studies document organ and function and structure,
in contrast to conventional radiology, which creates images based upon
anatomy. Many of the nuclear medicine studies can measure the degree of
function present in an organ, often times eliminating the need for surgery.
Moreover, nuclear medicine procedures often provide important information
that allows the physician to detect and treat a disease early in its course
when there may be more success. It is nuclear medicine that can best be
used to study the function of a damaged heart or restriction of blood
flow to parts of the brain. The liver, kidneys, thyroid gland, and many
other organs are similarly imaged.
Manipal Hospital, Bangalore are among the most recognized
center in Bangalore and has strived to provide the best of the treatment
and always has looked out to incorporate the latest techniques and technology
in Nuclear Medicines.
Our nuclear medicine department offers a wide spectrum of Radionuclide
imaging procedures and some of its applications are given below:
++High risk patients having strong family history of heart disease/ DM/
Hypertension.
++Equivocal/ false Treadmill test.
++To rule out impending ischemia in other territories for future cardiac
events in
patients recovering from acute MI.
++For assessment of viable myocardium in patients with old MI.
++Follow up of patients who have undergone CABG/Post angioplasty
++To evaluate ventricular dysfunction in patients receiving CARDIO-TOXIC
drugs.
++Liver Scan
++Thyroid Scan
++Gallium Scan
++Pulmonary embolism (COPD)
Nuclear Medicines in India FAQ's
What is Nuclear Medicine ?
Nuclear Medicine involves the use of radioactive materials, or Isotopes,
to obtain specific diagnostic information. These Isotopes transmit a pattern
of rays representing the organ size, shape and function. The rays are
detected by a special camera which, when coupled with a computer, produces
a characteristic image on a screen. The amount of radiation to which the
patient is exposed causes no significant danger. The tracer material a
radionuclide is eliminated from the body in a day or two. Complications
or side effects are rare.
What Will The Exam Be Like ?
The individual who will be performing the examination on you is known
as a Nuclear Medical technologist. This technologist has completed a rigorous
course of education and training, and works under close supervision of
the radiologist (a radiologist is a physician who specializes in the study
of imaged tests such as Ultrasound, X-Rays etc.) to assure the most accurate
results from your exam. Your technologist will gently position you on
the scanning table under the camera A radionuclide will then be injected
or taken orally. This makes it possible for the camera to detect certain
organs and their functions. Most scans require many different images and
perhaps a few position changes. You will be asked to lie still. Each scan
will take about three minutes some may take longer. Movement may result
in the need for additional scans.
How Long Will The Exam Take ?
Time may vary significantly depending on the nature of the study and other
factors. Your doctor will advise you of the amount of time needed for
your particular exam.
Is it safe to nurse my baby after administration of the isotope
?
Although very little radioactivity is excreted in the breast milk, it
is better to discontinue nursing for a time. How long you stop depends
on the agent administered and can vary 24 hours or longer. It is important
for you to let us know if you are breast feeding, just as it is important
to inform the nuclear medicine personnel if you are pregnant, or think
that you could be pregnant.

Is Nuclear Medicines used for Cardiac Study ?
There are several types of heart studies in Nuclear Medicine. The most
common study is a myocardial perfusion scan to access coronary heart disease.
This is usually a two part study. Typically, the first part is a resting
myocardial perfusion scan - scanning is performed about 30 minutes after
the tracer is given to the patient intravenously in a resting condition.
The second part is a stress myocardial perfusion scan. Injection of the
tracer is done while the patient is exercising on a treadmill machine.
If the patient cannot exercise well, a pharmacological stress study can
be performed instead. The patient will be given a medicine, that dilates
heart blood vessels or makes the heart work faster, before the radiotracer
is injected.
I'm scheduled for a nuclear medicine exam and have had a reaction to
X-ray dyes. What should I do ?
Nuclear medicine employs tracer amounts of radioactive drugs called radiopharmaceuticals,
not iodinated dyes used in X-ray and CAT scans. No allergic reactions
are expected to occur.
Is the radioactivity I will receive harmful ?
More than 9 million nuclear medicine exams are done each year in the India.
The amount of radiation received is about what an individual receives
to the whole body each year in the course of daily life (so called "background"
or "natural radiation"). It is comparable to many conventional
X-rays, and less than those X-rays using fluoroscopy such as GI series
and angiography. Nuclear medicine exams are among the safest of radiological
procedures.
Why may it be necessary for my child to be sedated ?
As in adults, the scanning procedure can take several minutes (possibly
up to 45 minutes). It is very important that the patient lie absolutely
still during the acquisition of the scan. In children, generally aged
6 months to 6 years, it is frequently necessary to use sedation. This
is always done in conjunction with a trained radiology nurse, your referring
pediatric physician, and sometimes the Department of Anesthesiology according
to our sedation policies. |
