Creutzfeldt-Jakob disease on MRI often missed by radiologists
April 16, 2010 -- TORONTO - General radiologists reviewing MRI scans missed 65% of cases of Creutzfeldt-Jakob disease -- most of which were later spotted by specialist radiologists more familiar with the condition, according to a study presented at the American Academy of Neurology annual meeting.
Small colon polyps on VC suggest presence of larger lesions
April 16, 2010 -- Individuals with several diminutive colon polyps on virtual colonoscopy studies are far more likely than other screening subjects to also have a larger colorectal lesion, say researchers from the University of Munich in Germany.
Skeletal PET gains support for pediatric bone scans
April 15, 2010 -- BOSTON - Skeletal scintigraphy with F-18 sodium fluoride is a safe and effective way to diagnose skeletal disorders in children and could be used instead of bone SPECT exams, according to research presented on Wednesday at the Society for Pediatric Radiology meeting.
Radisphere skirts local groups in bid for hospital contracts
April 15, 2010 -- That sound you hear might just be a dam breaking. Radiology's traditional model of community-based group practices suffered another blow last week with the launch of Radisphere National Radiology Group, which is bypassing local radiology practices to sign contracts directly with hospitals.
Automated exposure control delivers uneven CT dose reduction
April 15, 2010 -- Reducing tube current may be a popular way to lower CT radiation dose, but it's not necessarily an effective one. In a new study, medical physicists from Greece found that organ dose reductions resulting from tube current modulation with automated exposure control can vary -- especially in children.
MR scans may detect signs of early dementia in elderly
April 14, 2010 -- TORONTO - MRI can detect signs of white-matter hyperintensity in the elderly that may indicate three times the risk of developing dementia, according to a French study presented this week at the American Academy of Neurology's annual meeting.
CT shows abdominal fat is unreliable Crohn's treatment target
April 14, 2010 -- A few reports have associated abdominal visceral fat with more aggressive forms of Crohn's disease, but the strength of the association -- and the implications for treatment -- remain unclear. Researchers from Ireland decided to try CT to resolve the issue.
CT delivers 91% of total pediatric ER radiation dose
April 14, 2010 -- MDCT may be used half as often as general radiography for examining children in the pediatric trauma center at Johns Hopkins University, but the modality is responsible for 91% of the ionizing radiation exposure associated with diagnosing their injuries.
Computer analysis bolsters liver elastography performance
April 14, 2010 -- Computer-enhanced dynamic analysis of ultrasound elastography movies is a useful and reliable method for depicting liver hardness, yielding a high level of interreader agreement, according to research published April 14 in the World Journal of Gastroenterology.
