Erik L. Ridley[email protected]PACS/VNALossy compression performs well in abdominal CT imagesLossy compression techniques are effective in abdominal CT exams at a range of compression ratios, according to a pair of recent studies. Researchers in Austria judged 3D JPEG 2000 to be suitable at ratios up to 15:1, while a South Korean team found 5:1 JPEG 2000 to be visually lossless.January 15, 2008BreastMammo CAD results show reproducibility in serial examsThe sensitivity and reproducibility of computer-aided detection (CAD) software is consistently high for breast cancer detection in both initial and short-term follow-up digital mammograms, according to research published in the January issue of Radiology.January 9, 2008UltrasoundComprehensive musculoskeletal US exam offers most valueWhile a focused musculoskeletal sonographic exam can identify most abnormalities, a protocol-based exam allowed for identification of 98% of symptomatic abnormalities in a recent retrospective study, according to researchers from the University of Michigan Hospitals in Ann Arbor.January 2, 2008Digital 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, 2007Previous PagePage 281 of 388Next PageTop StoriesMolecular ImagingPET/CT scans show lung damage in stone workersThe metabolic activities occurring in the lungs of these patients have been unknown.CTSCCT: Study explores diagnostic accuracy of CCTACTSCCT: AI predicts coronary artery calcium scores from chest x-raysCTSCCT: CCTA model shows plaque volume changes in chest pain patientsSponsor ContentWhen CT meets the power of AI everyone benefits.
