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.
Recent studies show that CT lung screening is more sensitive than standard lung screening methods (ie, chest X-ray, sputum cytology) in detecting lung cancer. Unlike standard chest X-rays, CT lung screening takes cross-sectional images of the lungs. This allows the radiologist to see the lungs from top to bottom.
