Eric Barnes[email protected]CTSubtraction CTA boosts in-stent restenosis evaluationA new study of digital subtraction CT angiography (DSCTA) found that it vastly improved the visualization of the stent lumen by eliminating metallic artifacts, according to researchers from Japan. The technique was particularly effective in improving the assessment of very small stents.January 8, 2015CTAuntMinnie.com CT InsiderJanuary 6, 2015CTCAD for virtual monochromatic CTC images shows high accuracyA computer-aided detection (CAD) algorithm analyzed virtual monochromatic dual-energy CT colonography (CTC) images accurately with few false positives in a study from Massachusetts General Hospital. The researchers believe the study could pave the way to more accurate minimal-prep CTC.January 5, 2015CTAJR: CT shows evidence of lung cancer spread via airwaysNew research with CT supports the hypothesis that lung adenocarcinoma may spread through the airways and not just through the blood. So-called aerogenous metastasis of lung cancer has implications for staging, management, and prognosis and may be underrecognized, the authors report in the American Journal of Roentgenology.December 29, 2014AICAD detects lymph nodes at chest CTA new automated tool developed at the National Institutes of Health can detect mediastinal and abdominal enlarged lymph nodes more accurately than previous techniques, according to a presentation at the 2014 RSNA meeting.December 23, 2014CTChest CT referrals from x-ray yield high rate of abnormalitiesNearly half of patients who receive radiologist recommendations for chest CT to evaluate abnormal findings on chest radiography have clinically relevant findings at CT, including a substantial number of new malignancies, according to a new study in Radiology.December 22, 2014CTNonsolid lung nodules found on CT screening harbor few cancersNonsolid nodules detected with CT lung cancer screening are often indolent, and even when they do harbor cancer, the long lead times before such nodules develop make it safe to follow them up less often, according to new long-term data presented at the RSNA 2014 meeting.December 17, 2014CTCT ties emphysema to mortality, independent of other risksCT scans show that people with emphysema are at risk of earlier death than those without the disease, even if they have no evidence of chronic obstructive pulmonary disease or airflow obstruction, according to a study published on Monday in the Annals of Internal Medicine.December 14, 2014CTCoronary CTA plus stress MPI nails ischemia-causing lesionsCombined dual-energy coronary CT angiography and CT myocardial perfusion imaging (CCTA-MPI) improves both the identification and discrimination of ischemia-causing coronary artery stenoses over CCTA alone, according to a Korean study presented at last week's RSNA meeting.December 7, 2014CTFatty liver disease occurs with risky plaqueCHICAGO - People with nonalcoholic fatty liver disease are very likely to harbor high-risk atherosclerotic plaque as well, creating a double health hit that may have a common origin, researchers from Boston reported at RSNA 2014.December 3, 2014Previous PagePage 40 of 258Next PageTop StoriesDigital X-RayChest x-rays reveal atherosclerosis in patients undergoing amputationsLower limb amputation is an increasingly common major complication of advanced peripheral arterial disease and diabetes mellitus.MRI3D MRI technique helps plan treatment for pediatric heart conditionsWomens ImagingCould AI scoring help with managing DCIS?CTClinicians, beware: CT diagnostic accuracy varies by adnexal lesion typePractice ManagementRadiology coding update for 2026
