Eric Barnes[email protected]CTPanoply of VC studies yields significant extracolonic findingsA meta-analysis of VC studies has enumerated what radiologists have been noticing for years: that VC reveals important incidental abnormalities. The findings deemed "important" ranged from abdominal aortic aneurysms to early extracolonic cancers -- the latter detected at rates equivalent to that of breast cancer screening. The U.K. authors could only conclude that VC may become an important method of detecting early extracolonic cancers.March 22, 2005CTZero to 64: CT urography zooms ahead with more detector rowsThat more image details would be visible with additional CT detectors seems logical enough. But real-world examples have been sparse, and clinical studies comparing four scanner generations side by side are rare birds indeed. But two groups, from Boston and the Mayo Clinic, have focused their research on comparing generations of multidetector-row CT systems using a CT urography protocol.March 17, 2005CTProof of concept seen in microCT mouse VCHot on the tail of the first mouse MR colonography study, investigators in Wisconsin have established a technique to perform microCT virtual colonoscopy in 20 murine subjects from Madison.March 15, 2005CTHigh-concentration iodine quickly opacifies pig arteriesThe cardiovascular systems of humans and pigs are very much alike -- not only genetically, but in their ability to develop high cholesterol levels and clogged arteries. Such attributes make swine ideal candidates for cardiovascular research. In fact, researchers from Italy used them in a study of a high-concentration iodinated contrast agent not yet approved for marketing.March 9, 2005Clinical NewsRadial head-capitellum view best as adjunct in elbow x-rayVIENNA - When elbows are injured, the radial head-capitellum view makes a fine adjunct to the standard anterioposterior (AP) and lateral views when more information is needed. But the technique shouldn't be allowed to elbow its way into the standard imaging protocol, according to a presentation Tuesday at the European Congress of Radiology (ECR).March 8, 2005CTVC experts have an edge over less experienced readersVIENNA - The correct categorization of polyp size at virtual colonoscopy is crucial to patient management. Researchers of a multicenter study tested three reader groups and found wide variations between endoscopically and radiologically reported lesion sizes, and only subtle differences among the three groups in their ability to categorize lesions on VC software.March 7, 2005Industry NewsECR 2005 closes with plans set for next yearVIENNA - European Congress of Radiology president Professor Antonio Chiesa led the closing session of ECR 2005 today, appointing a new president, Professor Andreas Adam, to lead the organization toward next year’s meeting to be held in Vienna, March 3-7, 2006.March 7, 2005CTLow-dose 40-slice CT sees nonviable myocardiumVIENNA - CT has shown that it can find nonviable myocardium as well as MRI, but the dose is a whopper. Will it always be thus? A new study from the Netherlands concludes that 40-slice MDCT can detect nonviable myocardial tissue in less than a second -- and less than 1 mSv of radiation.March 6, 2005Nuclear MedicineMDCT staging may obviate bone scintigraphy in some patientsVIENNA - Cancer patients undergoing full CT staging may not always need a bone scintigraphy exam, thanks to the diagnostic accuracy of multidetector-row CT scanners. A study presented today at the tumor imaging sessions of the 2005 European Congress of Radiology found 16-slice CT to be statistically equivalent to scintigraphy for detecting skeletal metastases.March 5, 2005CTPostprocessing reveals earliest signs of cerebral infarct on plain CTVIENNA - A new postprocessing technique reveals early cerebral infarction by finding the subtlest areas of hypodensity on plain head CT. Such regions -- separated by a handful of Hounsfield units from the surrounding unaffected tissues -- are rarely visible to the naked eye.March 4, 2005Previous PagePage 210 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
