''The world's first computed tomography (CT) scan was performed in 1971 on a patient at Atkinson Morley Hospital in Wimbledon, now part of St George's Hospital. It was a brain scan performed by Sir Godfrey Hounsfield under the supervision of Jamie ...'

''The American College of Radiology issued a heads up on Thursday regarding potential payment denials at certain facility types. ACR highlighted the delivery of low-dose CT lung cancer screening at independent diagnostic testing facilities. Following a ...'

''We aimed to compare dedicated coronary computed tomography angiography (CCTA) followed by high-pitch scanning and triple-rule-out computed tomography angiography (TRO-CTA) in terms of radiation dose, contrast media (CM) use, and image quality. Patients ...'

''Modifications to pack-year history and smoking quit duration thresholds beyond those recommended in the 2021 United States Preventative Services Task Force (USPSTF) criteria for low-dose computed tomography lung cancer screening may more than double the ...'

''The aims of this study were to determine the objective and subjective image quality of high-pitch computed tomography (CT) angiography of the aorta in clinical dual-source photon-counting detector CT (PCD-CT) and to compare the image quality to ...'

''Previous studies have shown that low-dose, whole lung radiation in the form of X-rays can effectively treat severe pneumonia, with minimal side effects. Two clinical trials are applying a modern version of this concept to test patients who have acute ...'

''Solid-state radiation detectors use crystalline semiconductors, such as silicon or germanium, to directly convert X-ray photons into electrical current. Such devices outperform other detection technologies in terms of both sensitivity and detection ...'

''Children are a distinct group of patients in terms of medical imaging. Their size, physiology and the location of their organs change as the child grows, and the fact that children have a longer life expectancy than adults must also be taken into account ...'

''Common medical imaging procedures use low doses of radiation that are believed to be safe. A new study, however, finds that in human cell cultures, these doses create breaks that allow extra bits of DNA to integrate into the chromosome. Roland Kanaar and ...'

''CT protocols and radiation doses vary significantly across different countries, according to a new study published in the BMJ. The authors added, however, that developing a consistent standard 'should be possible.' It is important to minimize ...'
