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 CT scan of the chest may be performed to assess the chest and its organs for tumors and other lesions, injuries, intrathoracic bleeding, infections, unexplained chest pain, obstructions, or other conditions, particularly when another type of examination, such as X-rays or physical examination, is not conclusive. CT scan of the chest may also be used to evaluate the effects of treatment of thoracic tumors. Another use of chest CT is to provide guidance for biopsies and/or aspiration of tissue from the chest.
