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.
Patients also spend just 20 minutes in the scanner with PET/CT as compared to 45 minutes with conventional exams. Although NaF PET/CT scans deliver a slightly higher dose of radiation than conventional scans (5 mSv versus 7.4 mSv), the radiation exposure is still low. In fact, NaF PET/CT may prove accurate enough to reduce the need for additional imaging tests, leading to lower overall radiation exposure for patients.
