CAD may drive chest DR screening for tuberculosis January 5, 2011 -- A prototype computer-aided detection (CAD) algorithm for tuberculosis (TB) developed by Dutch researchers performed well in a pilot study, offering hope that the software could enable the use of chest digital radiography (DR) to screen for TB in areas with a high burden of the disease but not many skilled readers.
Dual-phase DECT myocardial perfusion cuts time, dose January 4, 2011 -- There's no need to acquire images during both stress and rest phases in dual-energy CT (DECT) myocardial perfusion imaging, say researchers from the U.S. and Germany. A stress phase combined with a delayed-enhancement phase performs just as well while reducing radiation dose by a third.
PET may help find cause for epileptic brain disease in kids January 3, 2011 -- With the help of FDG-PET, French researchers have discovered a common brain dysfunction among school-age children afflicted with fever-induced refractory epileptic encephalopathy, according to a study published in the January edition of the Journal of Nuclear Medicine.
NEA: Medical isotope shortages could become commonplace December 31, 2010 -- Supply shortages of molybdenum-99 could become commonplace over the next decade unless longer-term actions are taken, concludes a report from the Nuclear Energy Agency (NEA) of the Organization for Economic Cooperation and Development.
DR tomo reduces need for CT to confirm lung cancer December 23, 2010 -- Pairing low-dose digital radiography (DR) tomosynthesis with conventional radiography eliminates the need for three of every four CT scans typically performed to confirm lung lesions previously suspected on chest radiography, according to a study from the University of Trieste in Italy.
DETECT: Gadobenate dimeglumine preferred for breast MR contrast December 22, 2010 -- In a head-to-head comparison, gadobenate dimeglumine contrast offered significantly improved diagnostic performance in breast MR compared to gadopentetate dimeglumine, according to a study published online December 16 in Radiology.
Czech prenatal US screening program improves CHD detection December 21, 2010 -- A review of 21 years of experience from the Czech Republic's national prenatal ultrasound screening program found significant and improving antenatal detection of congenital heart disease (CHD). But mortality still remains high, according to the research published in Heart.
Radiation therapy comparable to surgery in elderly patients December 17, 2010 -- Stereotactic radiation therapy produces the same survival outcomes for elderly patients diagnosed with early-stage lung cancer as surgery, according to research presented at the 2010 Chicago Multidisciplinary Symposium in Thoracic Oncology.
C-11 PiB PET shows first progression of Alzheimer's disease December 16, 2010 -- For the first time, Swedish researchers have observed the progression of Alzheimer's disease with the use of PET and carbon-11-labeled Pittsburgh Compound B (C-11 PiB), according to a study published online December 13 in the neurology journal Brain.
Second-reader CAD improves VC sensitivity December 14, 2010 -- Computer-aided detection (CAD) works best in virtual colonoscopy when human readers do their job first, according to a new study. The use of CAD as a second reader improved both per-patient and per-polyp detection, while running CAD concurrently with the initial read was less effective.
