Prototype shows potential for patient-centered image sharing
August 29, 2012 -- Current image-sharing methods based on CDs are burdensome to both patients and providers alike and also raise privacy concerns. However, researchers from Wake Forest University have developed a patient-controlled prototype image-sharing framework that aims to tackle those problems.
ESC: 320-detector-row CTA plus perfusion helps triage patients
August 28, 2012 -- A two-step heart test consisting of 320-detector-row CT angiography (CTA) followed by CT perfusion helps separate patients who need invasive angiography from those who do not, according to results of the international CORE 320 study presented on Monday at the European Society of Cardiology (ESC) meeting in Munich.
Commercial screening tests, imaging overuse spike health costs
August 28, 2012 -- Screening tests that are sold directly to consumers by commercial firms without physician referrals inflate healthcare costs and erode efforts to provide high-value care -- and medical imaging is a big part of the problem, according to a pair of opinion articles published on August 27 in the Annals of Internal Medicine.
Simple procedures are keys to success of proton facilities
August 28, 2012 -- The use of proton therapy for prostate cancer patients is highly controversial because its high cost compared to other radiation therapy treatments has not been justified by superior patient outcomes. However, prostate cancer patients are essential for a proton therapy center's financial well-being.
ESC: Fractional flow reserve CT finds vessels causing ischemia
August 27, 2012 -- Fractional flow reserve CT in patients with significant stenosis can distinguish those with coronary artery disease who need revascularization from those who don't, concluded a study presented on Sunday at the European Society of Cardiology (ESC) meeting and published concurrently in the Journal of the American Medical Association.
MRI software from MGH offers better estimate of tumor volumes
August 27, 2012 -- Software developed at Massachusetts General Hospital (MGH) may offer a better way to estimate changes in tumor volume after treatment in soft-tissue sarcoma patients, giving physicians a better tool to track the effectiveness of therapy.
