Positron Emission Tomography (PET)

Positron Emission Tomography (PET)

A technique using short-lived radioactive substances which emit positrons, a highly sensitive way of detecting active tumor tissue. PET is offered at South Shore Hospital in partnership with Shields Health Care.

Ultrasound

A technique using high-frequency sound waves to create pictures of the body's organs. Since no ionizing radiation (x-rays) are used, it is ideal for imaging pregnant women and also is used for the neck, abdomen, pelvis and to examine blood vessels in the arms and legs.
