Eric Barnes[email protected]CTMI is visible on nongated chest CT, but often missedGeneral radiologists appear to be missing their chance to detect myocardial infarction (MI) during routine CT imaging. Researchers found that general radiologists prospectively detected fewer than half of MI on CT -- even though cardiac specialists found all of the cases when reviewing images after the fact.December 28, 2010CTQuantitative lung CT refines COPD diagnosis in smokersBy analyzing CT values in the affected lung regions, quantitative CT is improving the diagnosis of chronic obstructive pulmonary disease (COPD) to enable physicians to tailor treatment to individual patients, according to a study presented at the 2010 RSNA meeting.December 27, 2010CTAuntMinnie.com CT InsiderDecember 22, 2010CTReduced kVp CT still finds renal stonesUsing CT with a reduced tube-current protocol to image patients with suspected renal stones is as sensitive as full-dose studies, according to a research presented at this month's RSNA meeting by researchers from New York University.December 22, 2010CTCT predicts hemorrhagic transformation in stroke patientsPerfusion CT can predict the risk of hemorrhagic transformation in acute stroke patients with accuracy comparable to that of diffusion-weighted MR imaging, say researchers from Massachusetts General Hospital in Boston.December 21, 2010CTMinimal-prep VC achieves high sensitivity in large cohortUsing both electronic cleansing and computer-aided detection, a large multicenter trial has shown high sensitivity for minimal-prep virtual colonoscopy. The minimal-prep approach is being closely watched for its potential to nudge more adults into colorectal cancer screening.December 20, 2010CTVariable CT pitch cuts contrast dose in graft assessmentWhen using CT to assess graft patency after coronary artery bypass graft surgery, employing a variable-pitch technique speeds scanning and reduces contrast dose by a third, Japanese researchers said in a presentation earlier this month at the RSNA meeting in Chicago.December 19, 2010CTAuntMinnie.com Virtual Colonoscopy InsiderDecember 15, 2010CTMedicare paying for more diagnostic VC examsAcross the U.S., Medicare is paying for more diagnostic virtual colonoscopy exams and is issuing fewer reimbursement denials, according to a new study of U.S. data. However, the trend varies substantially by geographic region, researchers said in a presentation at this month's RSNA meeting in Chicago.December 14, 2010Industry NewsRiesgo de cáncer de pulmón mayor que de mama por TC torácicoCHICAGO - Aún en las mujeres, quienes enfrentan riesgos mayores que los hombres cuando reciben exámenes por TC, el riesgo de cáncer de pulmón supera con creces al de cáncer de mama, según los investigadores de la Universidad Médica de Carolina del Sur en Charleston.December 14, 2010Previous PagePage 110 of 258Next PageTop StoriesMRICheck for middle neck involvement for nasopharyngeal cancer prognosis"Our study establishes [MNI] as an independent prognostic determinant in N1 and N2 nasopharyngeal carcinoma," researchers wrote.Molecular ImagingPET links brain receptor to emotional numbing in PTSDWomens ImagingCEM, DBT show promise for preoperative breast cancer stagingMRIMRI illumines how the brain maintains 'representation' of phantom limbsDigital X-Ray3D DEXA reveals lower bone density in diabetes patients
