Radionuclide Scanning


Radionuclide Scanning

  • The best method of investigation is case of acute cholecystitis is Radionuclide Scanning.
  • Neuroendocrine tumors (NET) can be best detected by Radionuclide Scanning.
  • Radionuclide scan is done for parathyroid adenoma is Sesta MIBI scan.
  • A patient presents with acute renal failure (ARF) and complete anuria. The USG is normal. DTPA Scan(Radiorenogram) will give best information regarding renal function.
  • Investigation of choice for locating Parathyroid gland is Tc-Thallium Substraction Scan.
  • Functional Analysis of Kidney is best done by Radionuclide Scanning.
  • The most sensitive test to detect GI bleeding is Radiolabelled, erythrocyte scanning .
  • Best Diagnosis for Ectopic gastric mucosa of meckels diverticulum is Radionuclide Scan(Technetium-99 scan).
  • Thallium Scan is performed to detect reversible myocardial ischemia.
  • In radionuclide imaging, the most useful radiophar­maceutical agent for skeletal imaging is Tc-99m linked to methylene diphosphonate (99m Tc-MDP).
  • Tc-99 pyrophosphate is used for defining hot spots in myocardial infarction/avid infarct imaging
  • 99m Tc-Sc is used in imaging of reticuloendothelial system (liver/ spleen), gastric emptying, GI bleeds
  • Gallium 67 is used for tumours/abscess.
  • Gamma camera is used for measuring the radioactivity and Radionuclide Scanning.

Scans used for:

  1. Hot spot in MI: Technetium scan
  2. Pancreatic scanning: Selenium 75
  3. Parathyroids: Sestamibi scan
  4. Renal GFR estimation: Tc 99DTPA scan
  5. Vesicourethral reflex: MAG3 Tc 99 scan
  6. Thyroid scan: 1-131
  • Radionuclide Scan is initial investigation of choice for a patient presenting with solitary nodule of thyroid.
  • Curie is a unit for quantity of radionuclide disintegrating per second.
  • Investigation of choice in parathyroid pathology is Technetium-thallium subtraction scan.
  • DTPA radionuclide is best suited for measurement of GFR.
  • Biliary radionuclide scanning (HIDA scan) may be of help in the atypical case. Lack of filling of the gallbladder after 4 hours indicates an obstructed cystic duct and, in the clinical setting of acute cholecystitis, is highly sensitive and specific for acute cholecystitis. A normal HIDA scan excludes acute cholecystitis.
