Nuclear Medicine Program

Nuclear medicine is a specialty within medical imaging and radiology that uses small amounts of radioactive material to diagnose or treat a variety of diseases, including many types of heart conditions, cancers, and gastrointestinal, endocrine and neurological disorders. 

Nuclear medicine examinations provide unique information such as functionality of the organs and anatomic structure of the body that is often unattainable using other imaging procedures. Nuclear medicine imaging procedures are noninvasive. Apart from IV injections, they are usually painless medical tests that help physicians diagnose and evaluate medical conditions. These imaging scans use radioactive materials called radiotracers and radiopharmaceuticals (the mix of radiotracers and pharmaceuticals). 

Different procedures are used in each case, depending on the type of exam. Sometimes the radiotracer is either injected into the body, at other times swallowed or inhaled as a gas. This eventually accumulates in the organ or area of the body being examined.  The emissions are detected by a special camera or imaging device that produces pictures and provides molecular information.

The Nuclear Medicine Program at Tufts Medical Center in downtown Boston, MA offers a full range of radiopharmaceutical imaging. Radiopharmaceutical imaging is different from radiographic imaging. The former looks into the functionality of the organs. At Tufts Medical Center, a wide range of imaging is offered, including: 

  • Adult and pediatric cardiac nuclear medicine
  • Lympho-scintigraphy to localize sentinel lymph node before surgery for cancer
  • I-131 therapy and diagnostic imaging of thyroid diseases
  • Radioimmuno-therapy like Bexxar and Zevalin treatment for patients with lymphoma and PET

Risks of nuclear medicine

Because the doses of radiotracer administered are small, diagnostic nuclear medicine procedures result in relatively low radiation exposure to the patient, acceptable for diagnostic exams. Thus, the radiation risk is very low compared with the potential benefits.

Public announcement concerning a proposed health care project

PET/CT Services by Tufts Medical Center and Shields, LLC (“Applicant”) with a principal place of business at 700 Congress Street, Suite 204, Quincy, MA 02169 intends to file a request for an amendment to a previously issued Notice of Determination of Need with the Massachusetts Department of Public Health to add two (2) additional days of PET/CT imaging at Tufts Medical Center located at 800 Washington Street, Boston, MA 02111(“Amendment Application”). No capital expenditures will be necessary for the project, and there will be no cost implications or service impacts on the Applicant’s existing patient panel as a result of this project. Any ten Taxpayers of Massachusetts may register in connection with the intended Amendment Application by no later than February 16, 2020 or 30 days from the filing date, whichever is later, by contacting the Department of Public Health, Determination of Need Program, 250 Washington Street, 6th Floor, Boston, MA 02108.
