Low-dose CT scan
(loh-dose ... skan)
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. Low-dose CT scan 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 LDCT and low-dose computed tomography.
