Eric Barnes[email protected]CTCTA protocol slashes radiation dose tenfold in aortic diseaseA novel CT angiography (CTA) technique using nongated high-pitch images and iterative reconstruction delivered diagnostic scans across the board at about one-tenth the dose of standard exams, along with fewer motion artifacts and lower contrast media requirements, concludes a new study in Academic Radiology.May 10, 2015CTNew CT-based liver segmentation tool proves fast and accurateLiver segmentation, used to obtain liver volumes when planning for major interventions, can be automated without loss of accuracy compared to manual measurements, cutting procedure time by more than half, according to a new study in Academic Radiology.May 5, 2015CTCT reveals cardioembolic stroke that echo missesEchocardiography may be the de facto gold standard for cardiac evaluation of patients suspected of having cardioembolic stroke, but it isn't necessarily the best modality. A new study from Saudi Arabia used CT to discover several thrombi that echo had missed, along with other conditions.April 30, 2015CTNo cost difference between CTC, colonoscopy in elderlyA new analysis of Medicare data has found that after adjusting for patient demographic factors, costs are pretty much the same in the year following an initial screening exam for colorectal cancer, regardless of whether CT colonography (CTC) or optical colonoscopy is used, according to a report in Academic Radiology.April 29, 2015Image ProcessingLevelCheck algorithm targets wrong-site spinal surgeryA new algorithm called LevelCheck -- designed to prevent wrong-site spinal surgery -- boasted near-perfect accuracy in a trial by Johns Hopkins University researchers. By matching preoperative CT scans to intraoperative radiographs, LevelCheck confirms for surgeons that they are targeting the correct vertebral level.April 22, 2015CTARRS: Cancer diagnosis leads smokers to quitSmokers diagnosed with cancer are more likely to quit smoking than other smokers, according to a new study by the American Cancer Society presented at this week's American Roentgen Ray Society (ARRS) annual meeting in Toronto.April 20, 2015CTUC Davis group wins CT lung nodule surveillance grantResearchers from the University of California, Davis have received $2.3 million to run a new study aimed at improving surveillance practices for patients with small, low-risk lung nodules. The 26-center project will begin June 1.April 16, 2015CTCT technique enables single-kidney GFR calculationImprovements in CT hardware and software are enabling clinicians to measure glomerular filtration rate (GFR) in a single kidney, an advancement that replaces less accurate options and permits a range of useful new diagnostic tools, according to researchers writing in Radiology.April 15, 2015ISIT focuses on patients; teleradiology and ultrasound; is SPECT crying wolf?April 13, 2015CTHalf of positive SPECT patients negative at CCTANearly half of all patients who test positive on SPECT myocardial perfusion imaging are found to be negative at coronary CT angiography (CCTA), calling into question the routine use of SPECT myocardial perfusion imaging, a test that has been a mainstay of the diagnostic workup of patients with a clinical suspicion of coronary artery disease.April 12, 2015Previous PagePage 36 of 258Next PageTop StoriesRadiation Oncology/TherapyASTRO: Radiotherapy offers opportunities beyond cancer treatmentMolecular ImagingCase report: Pluvicto as a first-line treatment in late-stage prostate cancerMRINew brain MRI imaging technique could help identify Alzheimer'sRadiology EducationScholarly activity low among residency program directorsSponsor ContentDigital Innovations Shaping the Future of Radiology
