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. Read More
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. Read More
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. Read More
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. Read More
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. Read More
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. Read More
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. Read More
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. Read More
IOERT successful as boost during breast conservation surgery
December 14, 2010 -- Breast cancer patients undergoing breast conservation surgery who have an intraoperative electron radiation therapy (IOERT) boost followed by whole-breast irradiation have a much lower rate of cancer recurrence 10 years after treatment, according to a study presented at the San Antonio Breast Cancer Symposium.
