LDCT

A procedure that uses a computer linked to an x-ray machine that gives off a very low dose of radiation to make a series of detailed pictures of areas inside the body. The pictures are taken from different angles and are used to create 3-D views of tissues and organs. LDCT is recommended as a screening test for adults who have a high risk of developing lung cancer based on their age and smoking history. Also called low-dose computed tomography and low-dose CT scan.
