Eric Barnes[email protected]CTCoronary calcium found on CT packs extra peril for smokersAccording to an analysis of more than 44,000 subjects over five years, smokers with coronary artery calcium (CAC) had higher mortality rates than smokers without CAC. But an absence of CAC didn't help smokers much, as they still had mortality similar to nonsmokers with mild to moderate atherosclerosis, researchers wrote in JACC: Cardiovascular Imaging.October 10, 2012CTCanadian C-spine rule rules, but may not cut imagingThe Canadian C-spine rule is more accurate for diagnosing cervical spine injuries than another common rule addressing the injury, according to a new study in the Canadian Medical Association Journal.October 8, 2012CTNovel CT analysis tool refines COPD diagnosisA new image analysis technique for chest CT scans could have a big effect on the diagnosis and treatment of chronic obstructive pulmonary disease (COPD), according to a new study in Nature Medicine.October 8, 2012CTDSCT compares full- to half-dose VC by patientMayo Clinic researchers used iterative reconstruction to acquire half-dose virtual colonoscopy exams with dual-source CT (DSCT) and compare them to full-dose exams without scanning patients twice. The technique offers a more accurate way to compare dose levels between different CT protocols, according to a new study in the Journal of Computer Assisted Tomography.October 7, 2012CTAutomated tube current, voltage settings cut CT liver doseA software protocol that enables the use of both automatic tube voltage selection and automatic tube current modulation in the same CT scan can reduce radiation dose significantly in patients with suspected liver disease, according to a new study in Radiology by Korean researchers.October 4, 2012CTNoncontrast CT may underestimate lung nodule volumeLow-dose unenhanced CT scans may underestimate the volume of smaller lung nodules compared with standard-dose contrast CT studies, creating potential problems when tracking nodules over time, wrote researchers in the October issue of the American Journal of Roentgenology.September 30, 2012CTNLST stands alone in finding lung screening mortality benefitA new meta-analysis of lung cancer screening studies shows that only one of three randomized trials that looked at mortality found a benefit from screening. Still, the comparison is questionable inasmuch as the two studies analyzed along with the National Lung Screening Trial (NLST) may be too small with too little follow-up.September 27, 2012CTRadiology: Time to mothball 'low-dose' terminologyThe terms "low dose" and "standard dose" are meaningless, so if the paper you're submitting to Radiology includes them, expect to get it back, say the editors of the specialty's flagship journal.September 25, 2012CTFast video cards enlisted in drive to curb CT doseHigh-speed computer graphics cards are being used to provide faster and cheaper radiation dose estimates than supercomputer-based software that has traditionally taken several hours to compute doses from CT scans, say researchers from Rensselaer Polytechnic Institute.September 23, 2012CTCTA, not CTP, makes the call for ischemic stroke treatmentPatient outcomes also depend on factors such as ischemic preconditioning and the presence of collateral vessels, so perfusion CT imaging is unlikely to add much to the therapeutic decision, Lev said. Future research will model multiple univariate imaging predictors, including collateral vessels.September 23, 2012Previous PagePage 80 of 258Next PageTop StoriesCTRevealed: The cause of CT safety incident in BelgiumA single bottle of contaminated contrast agent was the cause of eight patients' illness after undergoing CT in Belgium.AIAgentic AI as the new infrastructure for interoperabilityWomens ImagingAI interpretation leads to high NPV, recall rates in breast imagingPractice ManagementHow does practice consolidation affect radiology services pricing?Sponsor Content"Join Us"
