gamma-camera-breast-tumors.jpg Tumors that went invisible with mammography are now visible with the new Gamma camera. Researchers at the Mayo Clinic in collaboration with GE Healthcare and Gamma Medica have developed a new device that is capable of identifying breast tumors, as small as 1/5th of an inch. The latest innovation in breast imaging uses a dual-headed gamma camera and is superior to currently used mammography for detection of tumors.

Procedure Review
a. Detects cancer tumors that go unidentified with the present mammography.
b. It can detect tumors of size less than 10 millimeters and tumors that are invisible on a
mammogram in women with dense breasts.
c. Although the device would cost a little more than mammography, it is more comfortable to women as low pressure (15 pounds) is used to image breast, compared
to 45 pounds pressure used in mammogram.
d. The procedure involves, where women would be injected with little amount of radioactive drug, which travels to tumors and is absorbed.
e. The Gamma camera then takes images of the women’s breasts.
f. The images show the absorption of the radioactive drug, the areas where the drug absorption is more, doctor’s presume that it might be due to cancerous cells.
g. The study results would be presented at 2006 meeting of San Antonio Breast Cancer Symposium, on Dec.16th of this year.
h. The device is not ready for regular use, as trial studies are expected to continue for next 2 years.
