Lack of IV contrast causes discrepancy in CT with PET scans
November 22, 2007 -- A study to determine the diagnostic limitations of low-dose, unenhanced CT scans performed for anatomic reference and attenuation correction during PET/CT has found that most discrepancies were due to the lack of intravenous contrast, which obscured liver metastases and lymph node recognition.  Discuss
New PET tracer may improve atherosclerotic imaging
November 15, 2007 -- Researchers in Massachusetts are showing progress in the development of a new PET tracer that could enhance the view of atherosclerotic inflammation, and also has potential for use in other imaging applications. The tracer could be useful in future hybrid imaging modalities like PET/MRI.  Discuss
Achieving (almost) painless data migration
November 9, 2007 -- Migrating data from an outdated archiving technology to a newer storage system can create issues for almost everyone involved. Frederick Behlen, Ph.D., co-chair of the HL7 Imaging Integration SIG and DICOM Working Group 20, discusses ways to help make data migration as painless as possible.  Discuss
FDG-PET, MRI show worth in tumor treatment response
November 2, 2007 -- A research study from the University of Michigan in Ann Arbor finds that diffusion MRI and FDG-PET are two influential imaging biomarkers for quantifying tumor inflammatory response and macrophage infiltration after treatment.  Discuss
Report: Nuclear medicine patient visits drop in 2006
October 16, 2007 -- The total number of patient visits for nuclear medicine procedures declined in 2006, but shows a rebound in 2007, based on results for the first half of this year. The study by IMV Medical Information Division of Des Plaines, IL, estimates there were 15.2 million patient visits in the U.S. in 2006, compared with 17.2 million in 2005, a decline of 12% among 7,320 hospital and nonhospital sites.  Discuss
German-U.S. team successfully tests PET ring inside MRI system
October 10, 2007 -- German and U.S. researchers and engineers are showing early success with a prototype hybrid PET/MRI system, which features a full-ring PET insert installed inside a 7-tesla MR scanner. The team from the University of Tübingen, Burker BioSpin MRI, and Siemens Preclinical Solutions recently presented the results of its study on the performance of the hybrid PET/MRI small animal imaging system.  Discuss
FDG-PET CAD scheme boosts diagnostic accuracy for Alzheimer's
October 2, 2007 -- With the number of cases of Alzheimer's disease and other dementias expected to rise over the next 10 years, researchers are looking for ways to improve diagnostic accuracy. In a new study, researchers used an artificial neural network (ANN) computer-aided detection (CAD) scheme with FDG-PET for Alzheimer's disease with multicenter data, and found it was able to enhance diagnostic accuracy.  Discuss
Making a justifiable case for IT investment
September 27, 2007 -- Information technology has become an important tool in reducing medical errors and improving patient care and safety. While some providers see IT as a godsend, others perceive it simply as a necessary evil and need to be assured of tangible benefits from any IT capital expenditure. James Oakes of Healthcare Information Consultants, an IT investment consultant firm in Baltimore, recently discussed the due diligence process facilities should consider before making a major IT commitment.  Discuss
Rhode Island sets off on path for statewide HIT exchange
September 21, 2007 -- To make patient data more readily available to hospitals and other providers, Rhode Island is creating a statewide health information exchange (HIE). While the state starts to undertake this ambitious project, other organizations around the U.S. are watching closely, hoping to learn from Rhode Island's experience.  Discuss
SPECT/CT offers better bone scan views to enhance treatment
September 21, 2007 -- Combining SPECT and CT into a single hybrid modality can improve physicians' views of bone scans, as well as the confidence levels of their own diagnoses. Two recent studies are showing SPECT/CT's value in managing cancer patients and patients with back pain.  Discuss
