Nuclear Medicine


Cardiac nuclear medicine studies provide pictures of the structure and function of
the heart to help diagnose heart disease.

A. Myocardial Perfusion imaging Sestambi Stress and Rest Tests (Treadmill
and Pharmacologic)
B. Radionuclide Ventriculography MUGA (Multigated Analysis) for
determination of ejection fraction, wall motion and shunt.

Plays a role in the assessment, diagnosis and monitoring of patients with respiratory
disease. It focuses on the diagnosis of pulmonary embolism and investigation of the
intrapulmonary infection and neoplasm.

A. Dacryoscintigraphy
Nasolacrimal Drainage System (NLDS) Obstruction

Contributes significantly to diagnosis, treatment planning, and the evaluation of response to treatment in patients with cancer. Tumor-specific radiopharmaceuticals are being used for non-invasive, targeted tumor therapy.

Radiopharmaceuticals with underlying uptake mechanisms are used to detect
Inflammatory disease or occult infection in patients.

A. Gallium Scan
B. Indium-WBC Scan

Permits the study of specific functioning signals of the blood/ brain barrier, blood
flow, metabolism (oxygen, glucose, amino acids), and neurotransmission (dooamine,
benzodiazepine, serotonin receptors).

A. Celebral Perfusion imaging
B. Cisternography
C. CSF shunt Patency/CSF Leak

Radionuclide imaging in endocrine disease helps obtain the functional and
morphological information on the affected endocrine organs especially in thyroid,
paratyroid, and adrenal disorders.

A. Thyroid Scan
B. Parathyroid Scan
C. Thyroid Uptake and Scan
D. Thyroid Uptake Measurement Only
E. Metaiodobenzylguanidine(MIBG)
Scan for Pheochromocytoma

  1.  Radioactive Iodine Therapy for:
    • Hyperthyroidism
    • Autonomously Functioning Thyroid Adenomas
    • Multinodular toxic Goiter
  2. Radioactive Iodine Ablation of Differentiated
    Thyroid Carcinomas and Metastases
  3. Radiouclide Therapy for Malignant Bone Pain Palliation
    Radioactive Iodine Therapy
    Radiation Monitoring after intake of the Radioactive Iodine Capsule


Test Requiring Special Preparation from Patients

l-131 Uptake and Thyroid Scan / RAI Treatment Whole Body Scan

  • No solid or oral intake at least 2 hours prior to scan.
  • Upon Clearance of attending physician, patient has stopped taking the following:
    • Anti-Thyroid Medications such as Methimazole / Carbimazole /
      Neomercazole / Strumazole for 3-5 days, and PTU (propylthiouracil)
      for 7 days prior to scan.
    • Pro-Thyroid medications such as Euthyox / Elthroxine / Tryrax /
      Synthroid for 1 month, and Tertroxin (T3) for 2 weeks prior to scan.

Cardiac Scan (Myocardial Scan or Thallium Scan)

  • No Solid or Liquid oral intake at least 4 hours prior to scan.
  • Abstain from any caffeine (Coffee, Tea, Chocolate, Softdrinks, and the like)
    for 24 hours before the test.
  • Wear loose clothing and rubbershoes if you are to undergo a treadmill test.
  • Medicines to be stopped prior to scan.
    • -Calcium Channel Blockers such as Amlodipine, & Nifedifine for 2
    • -Beta Blockers such as Trimetazidme, Nicarandil & Nitroglycerin for 1

Liver and Hepatobiliary Scan

  • No solid or liquid oral intake at least 4 hours prior to scan.
  • Patient should withhold IV morphine or similar pain medications 4 hours
    prior to the study.
  • Pediatric Variation for Biliary Atresia
    • Phenobarbital at a dose of 5mg/kg/day is given for 5 days.


Administering the Drug

The patient receives a chemical compound containing a small amount of radioactive substance. The substance is called is radiopharmaceutical, a radioisotope or radiotracer.

It may be administered through:
-injection or IV
Special tubing

Waiting Time

The patient may be asked to wait for a certain period of time before the actual scanning begins, During this time, the radioactive material travels to its target but the amount of time depends on the type of scan to be performed. i.e. Thyroid Scan: range of 10-20 minutes Bone Scan: range of 2-3 hours

Taking the Scan of Picture

The patient will be positioned next to a special detector called the GAMMA CAMERA which will provide images and readings of the studied organs and tissues.This equipment does not emit radiation. It Simply picks up photons emitted by the body for the radiotracer the patient received earlier.

During the process of scanning, the patient should breathe normally and remain still while pictures are being taken. Any movement may distort the images and make the results difficuly to interpret, thus increasing the likelihood of repeating the test.

Interpreting the Scan

Once the exam is completed, the images and readings acquired are reviewed and interpreted by a Nuclear medicine Specialist. The result may then be correlated with other results, such as x-rays and pathology reports to enable the interpreting physician to reach a better understanding of the patient’s medical problem.


Are nuclear medicine procedures safe?

Nuclear Medicine procedures are very safe. A patient receives only an extremely
small amount of radiotracer, just enough to provide accurate diagnostic information.
The radiotracer remains in the body for a short period of time and is cleared from
the body through natural bodily functions. Drinking plenty of fluids will help clear the
tracer from the patient’s body.

Do these radiotracers cause side effect?

Adverse reactions or side effect are rare, but the patient needs to inform the technologist if he/she experiences any untoward symptoms during or after the tracer injection.

Can I resume my daily activities after the test?

Patients may resume their daily activities after the test. Instructions will be given by the technologist regarding contact with other persons depending on the test taken or amount of tracer the patient has received.

Who performs my Nuclear Medicine test?

All test are performed by a licensed Nuclear Medicine technologist; while a Nuclear Medicine Specialist interprets the images.

When I am not allowed to undergo nuclear Medicine Procedure?

Generally, Nuclear Medicine Procedures are not recommended for pregnant women and lactating mothers, unless otherwise indicated.

What is Nuclear Medicine?

Nuclear Medicine is a specialty that uses very small amounts of radioactive material
to diagnose and sometime treat a disease. It can provide:

  • Accurate Images of the anatomy of the body
  • Valuable Information about organ and tissue function
  • Therapy as a way to fight some disease.
