MR Shines Light on Pancreatic Flow
August 13th 2011A formidably named bit of technology can open a new window into pancreas function, according to a new study in the journal Radiology. Serial magnetic resonance cholangiopancreatography (MRCP) with a spatially selective inversion-recovery (IR) pulse can provide insights into pancreatic flow noninvasively, Japanese researchers reported.
PET Parses Alzheimer’s, Other Cognitive Impairments
August 8th 2011Positron emission tomography (PET) scans using F-18 florbetaben (18F-FDG) clearly distinguished patients with Alzheimer’s disease from those with frontaltemporal lobar degeneration (FTLD) and other cognitive impairments, according to a study in the Journal of Nuclear Medicine.
‘PET score’ Tops Neuropsych Testing in Tracking Alzheimer’s Progression
August 4th 2011Positron emission tomography (PET) scans using F-18 florbetaben (18F-FDG) are more reliable than traditional neuropsychological testing in tracking the evolution of mild cognitive impairment to Alzheimer’s disease, researchers reported in the Journal of Nuclear Medicine.
CAD Ineffective, Counterproductive For Breast Cancer Patients
July 27th 2011Computer-aided detection (CAD) technology fails to spot breast tumors and increases a woman's risk of being called back for needless post-mammography testing, according to a new study published online today in the Journal of the National Cancer Institute.
CT Bests Barium in Adult Celiac Disease Diagnosis
July 22nd 2011Improvements in computed tomography (CT) resolution of the small bowel, colon, and mesenteric lymph nodes have pushed CT scans ahead of traditional barium examinations in the diagnosis of celiac disease, according to a new study in the journal RadioGraphics.
fMRI Study: Concussions Disrupt Connections in Thalamus
July 20th 2011Patients with mild traumatic brain injury (MTBI) exhibit abnormal functional connectivity in the thalamus, a relay station for transmitting information throughout the brain, according to a new fMRI study published online in the journal Radiology. The findings could have implications for treatment strategies.
IMRT Safety the Focus of New ASTRO Report
July 18th 2011The report broadly addresses safe delivery of IMRT, with a primary focus on recommendations for human error prevention and methods to reduce the occurrence of errors or machine malfunctions that can lead to errors or “catastrophic failures,” ASTRO officials said.
PET Scans with Florbetapir F 18 Help Alzheimer’s Diagnosis
July 15th 2011Positron emission tomography (PET) combined with the tracer florbetapir F 18 showed significant differences in beta-amyloid burden in the brains of patients with probable Alzheimer’s disease, mild cognitive impairment, and healthy older adults, according to a new study.
ACR Blasts ‘Significant and Unwarranted’ Medicare Imaging Fee Cuts
July 7th 2011“Significant and unwarranted” medical imaging cuts in the Proposed Medicare Fee Schedule Rule for 2012, on top of “extreme” cuts to imaging services over the last five years, will drive many imaging providers from practice, restrict access to care, even for procedures not specifically affected by the cuts, and may actually increase Medicare costs for many of these services, the American College of Radiology said Tuesday.
Embedded Decision Support Key to PACS Success
July 4th 2011Radiology decision support tools are a bit like sunscreen – they can keep you from getting burned, but only if you bother to use them. That’s the conclusion of a new study in the July issue of the Journal of the American College of Radiology.
University of Chicago Licenses CT Gene-Protection Drug
July 1st 2011The University of Chicago has acquired technology and intellectual property rights for the development of amifostine, a drug researchers hope can prevent genetic changes caused by a variety of sources of ionizing radiation exposure, including common Computer Tomography (CT) scans.
