The Darling River, 1,160 miles (1,879 km) in length, flows southwest from the edges of the Great Dividing Range into the Murray River. The Murray rises in the Australian Alps and flows 1,200 miles (1,930 km) to the Spencer Gulf, directly west of Adelaide.
In lung cancer screening, individuals who have a high risk of developing lung cancer but no signs or symptoms of the disease undergo low-dose computed tomography (LDCT) scanning of the chest.
A chest computed tomography (to-MOG-ra-fee) scan, or chest CT scan, is a painless, noninvasive test. It creates precise pictures of the structures in your chest, such as your lungs. Noninvasive means that no surgery is done and no instruments are inserted into your body. A chest CT scan is a type of x ray. However, a CT scan's pictures show more detail than pictures from a standard chest x ray. Like other x-ray tests, chest CT scans use a form of energy called ionizing radiation. This energy helps create pictures of the inside of your chest.
