Eric Barnes[email protected]CTReconstruction kernel dramatically affects stent evaluationVIENNA - If the results of a phantom study are valid in patients, the choice of reconstruction kernel with 64-slice CT has a critical impact on coronary artery stent evaluations. And as Dr. Florian Wolf explained at today's cardiac imaging sessions at the European Congress of Radiology (ECR), the evaluation of stents for detecting restenosis is critical for patient outcomes.March 10, 2007CTCoronary CTA saves money in intermediate-risk individualsVIENNA - Studies continue to show the value of coronary CT angiography (CTA) in individuals at high risk of coronary artery disease, but its value in individuals at intermediate risk is unclear. Now researchers of a new study, presented at the European Congress of Radiology (ECR), report that CTA is not only warranted for individuals in the middle of the Framingham risk profile, but that it saves money compared to other diagnostic modalities.March 9, 2007CTItalung-CT results show efficacy of lung cancer screeningVIENNA - The first results of a sizeable Italian multicenter screening trial suggest once again that CT screening of smokers is effective in finding lung cancer in time to cure it. Presented at the European Congress of Radiology (ECR), the results are among the first of several randomized trials undertaken to assess the efficacy of CT lung cancer screening.March 8, 2007CTMDCT offers cost-effective, reliable diagnosis in low-risk angina patientsAs many as 6 million patients with chest pain are admitted to emergency departments every year in the U.S. Coronary CT angiography (CTA), despite real limitations, has been shown to diagnose some patients quickly and accurately. In a new study, 64-slice CTA provided the correct diagnosis in 95% of patients with low-risk acute chest pain, leading the authors to conclude that CTA was well suited to diagnosing this population. Still, a quarter of the patients needed additional examination to determine that CT had been correct all along.March 6, 2007CTMR colonography disappoints in reduced-prep protocolThe largest MR colonography (MRC) study of its kind to date showed high specificity, but disappointing per-polyp sensitivity, for a reduced-prep technique in patients in a low-prevalence population. Still, most patients with significant polyps were identified, according to the researchers from the Netherlands.March 5, 2007CTCalcium scoring requires individualized reconstruction phasesPreset reconstruction phases won't cut it for retrospectively gated CT calcium scoring -- not if you want accuracy and reproducibility. A preliminary but ongoing study from the Netherlands has found that large errors can be introduced by the use of predetermined reconstruction intervals, particularly when hearts beat fast.March 4, 2007Digital X-RayAuntMinnie.com Cardiac Imaging InsiderFebruary 27, 2007CTCT spot sign predicts hematoma expansion in stroke patientsIn patients with intracerebral hemorrhage (ICH), hematoma expansion in the first critical hours after symptom onset is associated with significantly poorer outcomes. Thanks to CT imaging and a new drug in the pipeline, it may be possible to identify and treat ICH patients at risk of hematoma expansion while there is time to improve outcomes, according to two new studies.February 25, 2007CTAuntMinnie.com CT InsiderFebruary 20, 2007CTASPECTS stroke scoring improved with perfusion CTThe Alberta Stroke Program Early CT Score (ASPECTS) rates the presence or absence of ischemia in 10 regions of the brain. Paired with noncontrast CT when a patient presents with stroke symptoms, ASPECTS has been shown to effectively predict which patients will benefit from thrombolytic therapy. A recent study using perfusion CT has found that ASPECT increases the accuracy for predicting radiological and clinical outcomes over noncontrast CT.February 20, 2007Previous PagePage 179 of 258Next PageTop StoriesMolecular ImagingPET predicts faster cognitive decline in women than menWomen initially outperformed men at low brain tau levels, but the advantage diminished as tau levels increased over time.MRIUnclear explanations of contrast MRI exams heighten patient anxietyWomens ImagingMammography screening improves survival for late-stage cancersUltrasoundUltrasound MinnieCast, Episode 2: Body imaging with RUS-PATSponsor ContentHow Agentic AI Is Transforming Radiology Ops
