'''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 ...'

'''Computed tomography-derived fractional flow reserve (FFR-CT) may have a lower positive predictive value (PPV) than expected, according to a new analysis published in JACC: Cardiovascular Imaging.[1] How could this impact its overall value? FFR-CT has ...'

'''The first of an innovative range of high-performance X-ray CT (computed tomography) systems offering enhanced levels of precision, resolution and scan speed has been introduced and is ready to order from the Industrial Metrology Business Unit (IMBU) of ...'

'''Keya Medical has launched the DeepVessel FFR, a software device that utilizes deep learning to facilitate fractional flow reserve (FFR) assessment based on coronary computed tomography angiography (CCTA). Cleared by the Food and Drug Administration ...'

'''Magnetic resonance imaging (MRI) guidance in stereotactic body radiotherapy (SBRT) for prostate cancer offers significant advantage over computed tomography (CT) guidance, with lower physician-scored toxic effects and patient-reported symptom burden, ...'

'''For computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography computed tomography (PET/CT), Dr. Sahani said contrast media is utilized in the majority of these exams for cardiovascular imaging and oncology imaging in ...'

'''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 ...'

'''The U.S. Food and Drug Administration (FDA) Sept. 30 cleared the world's first photon-counting computed tomography (CT) scanner, the Siemens Naeotom Alpha. Both the FDA and CT experts say this is the start of a revolution in new CT scanner technology, ...'
