Eric Barnes[email protected]UltrasoundEuropean, U.S. societies publish 3D echo guidelinesA joint committee of the European Association for Echocardiography and the American Society of Echocardiography has issued the first joint guidelines for image acquisition using 3D echocardiography.January 3, 2012CTCCTA shows cardiac revascularization beats statins aloneA study of more than 15,000 patients who underwent coronary CT angiography (CCTA) found that revascularization in patients identified by CT as high risk was associated with far fewer deaths than medical therapy (e.g., statins) alone.January 1, 2012CTAuntMinnie.com CT InsiderDecember 28, 2011PACS/VNATeleradiology brings VC to island outpostVirtual colonoscopy outperformed optical colonoscopy in an unusual teleradiology project that successfully screened hundreds of patients in Madeira, a Portuguese island off the coast of Morocco.December 26, 2011CTCT technique predicts transient vs. persistent lung nodulesAn image analysis technique presented at the RSNA 2011 meeting could facilitate CT lung cancer screening by differentiating potentially malignant part-solid nodules from the transient kind that are less worrisome.December 26, 2011CTNonobstructive plaque at CT shows higher mortality riskAn analysis of more than 10,000 patients with nonobstructive coronary artery plaque has found that statin use can reduce mortality by as much as half in patients at high risk at coronary CT angiography and using traditional risk measures.December 22, 2011CTAuntMinnie.com Virtual Colonoscopy InsiderDecember 21, 2011CTStudy finds happier patients with laxative-free VC prepA laxative-free virtual colonoscopy bowel preparation significantly improved the patient experience in a study of more than 600 screening subjects by researchers at Massachusetts General Hospital and three other U.S. institutions.December 20, 2011Cardiac ImagingAuntMinnie.com Cardiac Imaging InsiderDecember 19, 2011BreastDespite guidelines, older adults continue cancer screeningAfter age 75, routine screening is no longer recommended for cervical, prostate, breast, and colorectal cancers. But that inconvenient truth hasn't stopped older Americans from continuing to get the tests, according to a study appearing today in the Archives of Internal Medicine.December 11, 2011Previous PagePage 92 of 258Next PageTop StoriesWomens ImagingBreast imaging reads are shifting from generalists to specialistsSubspecialization may improve patient care, according to researchers.Practice ManagementRadiologists net $824M in industry research paymentsPractice ManagementImaging societies sound off on CMS MPFS final rule for 2026Digital X-RayAI predicts death risk from COPDSponsor ContentClinically Meaningful AI Detection of Interval Cancers
![Pittsburgh Compound B (PiB) PET distribution volume ratio (DVR) images were projected onto fsaverage surfaces from FreeSurfer and surface smoothed, with PiB (amyloid) slope maps created using ordinary least squares regression (time as only factor) and mixed effects models for 154 participants run at each vertex (P < .01; model: longitudinal Geriatric Depression Scale score estimated by amyloid slope × time + [sex + education + age] × time). This map visualizes the results of the linear mixed-effects models (t score of the main variable, amyloid slope × time) such that regions with a greater t score (red) represent areas in which greater depressive symptoms are associated with greater amyloid accumulation (amyloid slope). Anatomical landmarks are provided: L refers to the left hemisphere, R refers to the right hemisphere, and additional labels indicate the anterior and posterior ends of the brain.
