Erik L. Ridley[email protected]Digital X-RayPrevention key for reducing CR, DR image artifactsBy being aware of the causes of computed radiography (CR) and digital radiography (DR) image artifacts, users can develop appropriate countermeasures to reduce their occurrence, according to research presented at the 2007 RSNA meeting in Chicago.December 24, 2007UltrasoundAuntMinnie.com Ultrasound InsiderDecember 20, 2007CTCAD offers value in detecting lung nodules with CTComputer-aided detection (CAD) technology offers a relatively high detection rate for detecting lung nodules on CT scans, according to two studies presented at last month's RSNA 2007 meeting in Chicago. The first analyzed the performance of a CAD scheme for detecting lung nodules of various sizes and patterns on thin-slice CT studies, while the second study looked at CAD's effect on the performance of thoracic radiologists for detecting lung nodules.December 16, 2007AIAuntMinnie.com Advanced Visualization InsiderDecember 11, 2007PACS/VNAClinicians still need access to older imaging studiesReferring physicians still require the ability to access medical images older than one year, according to researchers from the University Medical Center Groningen in the Netherlands. They looked at how many older studies were requested by referring physicians after seven years of fully digital radiology operations, and presented their findings at the recent RSNA 2007 meeting in Chicago.December 9, 2007UltrasoundCEUS aids in discriminating hypoechoic prostate lesionsContrast-enhanced grayscale transrectal ultrasound (CETRUS) may offer value in characterizing peripheral zone hypoechoic prostate lesions, according to research presented at the recent 2007 RSNA meeting in Chicago. Contrast-enhanced ultrasound offers an innovative approach for imaging neovascularity associated with prostate cancer, the team from China reported.December 5, 2007PACS/VNAAuntMinnie.com PACS InsiderDecember 4, 2007CT'Patch view' may improve efficiency of VC CAD viewingCHICAGO - A new method for viewing virtual colonoscopy computer-aided detection (CAD) results may be more efficient than traditional sequential browsing of CAD hits, according to a pilot study presented at the 2007 RSNA meeting.November 28, 2007PACS/VNACommunicating abnormal findings to clinicians may not ensure follow-upCHICAGO - Directly communicating abnormal findings and follow-up recommendations to clinicians does not guarantee they will always follow through with additional imaging studies, according to research presented Wednesday at the 2007 RSNA meeting.November 27, 2007PACS/VNAConsumer displays compare well with medical-grade displaysCHICAGO - While medical-grade displays offer a longer life span and superior consistency over time, the growing capabilities and significantly lower cost of consumer displays may offer a more compelling PACS display alternative, according to research presented at the 2007 RSNA meeting.November 26, 2007Previous PagePage 286 of 393Next PageTop StoriesCTNew benchmark helps monitor cumulative CT radiation doseThe findings highlight the need for systematic dose tracking and rigorous justification of imaging.Radiation Oncology/TherapyStudy questions routine use of radiotherapy after bone surgeryUltrasoundCEUS outshines color Doppler imaging for indeterminate kidney lesionsWomens ImagingWomen's Imaging MinnieCast, Episode 2: Risk-based vs. annual mammography screening, part 1Digital X-RayChest x-rays reveal atherosclerosis in patients undergoing amputations
