Sentinel node localization is a technique used locate the sentinel lymph nodes. Patients who have been diagnosed as having cancer, most commonly breast cancer and melanoma, may require surgery to remove the primary cancer and also some nearby lymph nodes. The initial spread of these types of cancer is often via the lymphatics.
Salivary Gland Scintigraphy or Salivagram is a Nuclear Medicine scan used to show the function of the salivary glands. Abnormal salivary function can be seen in patients with symptoms such as dry mouth, bad breath and may be associated with a sensation of dry gritty eyes. The scan is also a useful way
The Milk Scan is done to demonstrate the presence of gastroesophageal reflux, its extent in the esophagus and delayed images for evaluation of aspiration. Gastroesophageal scintigraphy is a convenient, tubeless, and accurate technique for detecting gastroesophageal reflux that can be performed rapidly with minimal patient discomfort. The procedure is currently being utilized throughout the
Lung Perfusion is a scan of the lungs showing the distribution of blood in the lungs. The lungs are made of multiple segments each with its own air and blood supply. The test is most commonly used to diagnose a clot in the lung (pulmonary embolus). ❰❰ PATIENTS
Direct Radionuclide Cystography is a diagnostic nuclear test that uses a solution containing radioactive material to outline the bladder to diagnose conditions such as reflux, distention or incomplete emptying. ❰❰ PATIENTS INSTRUCTIONS • This procedure requires exposure to radioactive material. • If there is a possibility
Cortical Renal Scintigraphy assesses kidney function and displays viable kidney tissue. It is based upon the use of the radioactive tracer, Tc-99m dimercaptosuccinic acid (DMSA). This agent is delivered to the renal cortex and is retained for several hours. This allows measurement of relative left and right renal (kidney) function and is a very
Dynamic Renal Scintigraphy can determine overall renal (kidney) function and also relative left and right kidney function. The test is performed using the radiotracer called Tc99m-DTPA (Diethylene Triamine Pentacaetic Acid) or Tc99m-MAG3 (Mercaptoacetyltriglycine). The test is often used in combination with a diuretic drug such as frusemide to determine if a kidney is
A Meckel's Diverticulum Scintigraphy is a nuclear medicine test that detects the abnormally-located gastric mucosa. Gastric mucosa is the mucous membrane layer of the stomach. Meckel's diverticulum is an abnormality in the small intestine that is present at birth. ❰❰ PATIENTS INSTRUCTIONS • This procedure requires an
G.I.T. Protein leak Study is for detection and localization of protein leakage from the blood stream into the intestine.The site of active protein leak is identified by leak of 99mTc-labeled HSA within the bowel lumen. Chronic protein leak bleed can be by intestinal lymphangectasia. ❰❰ PATIENTS INSTRUCTIONS •
Gastric emptying study is a test that evaluates the process of emptying food from the stomach. For a gastric emptying study, a patient eats a meal in which the food or beverage is mixed with a small amount of radioactive material. A "Gamma Camera" is placed over the stomach to monitor the amount of
