Hybrid techniques make giant strides in clinical practice
March 4, 2015 -- As hybrid imaging gains more ground in cardiology, neurology, and oncology, the debate over PET/MRI's current and potential role in routine practice still rages. The central question remains: Is it an expensive new toy with no clinical applications on the horizon, or is it a truly revolutionary technique?
MR images improve PET quantification
February 27, 2015 -- MRI-guided filtering and partial volume correction of brain PET scans can enhance image quality -- particularly signal-to-noise ratio and spatial resolution -- and structure delineation, according to new research.
French report breakthrough in medical isotopes
February 19, 2015 -- Medical physicists from Nantes, France, have generated a series of medical isotopes from the irradiation of thorium-232. One of the products decays into a promising isotope for alpha radionuclide therapy, while another product is a sought-after isotope used in diagnostics.
Adrian Dixon: Team spirit's the key to success
February 17, 2015 -- LONDON - Building and maintaining team spirit must be an urgent priority for the global imaging community, said Dr. Adrian Dixon in a special lecture to mark the 40th anniversary of the U.K. Royal College of Radiologists.
Nuclear medicine physicians must change to survive
February 16, 2015 -- While nuclear medicine is not in imminent danger of extinction, it may need to reinvent itself for the future, according to the president of the British Nuclear Medicine Society. In particular, nuclear medicine physicians need to shed their self-image as purely imaging-based physicians to become more involved in clinical areas.
New tracer could help HNSCC patients avoid surgery
February 12, 2015 -- With the help of a novel radiotracer, researchers were able to accurately identify sentinel lymph nodes in patients with head and neck squamous cell carcinoma (HNSCC), potentially reducing the number of patients who need to undergo selective neck dissection.
Proton therapy: Coming soon to the U.K.
February 6, 2015 -- Against the stunning backdrop of the Clifton Suspension Bridge in Bristol, delegates at last week's U.K. College of Radiographers' Annual Radiotherapy Conference heard about the latest plans for the implementation of proton therapy.
Breaking the resolution limits of SPECT
January 30, 2015 -- Molecular imaging is essential for research of human disease because it enables noninvasive visualization of minute structures at the sub-organ and/or sub-tumor level. Its use has been constrained, however, by the challenge of producing images with high enough spatial resolution, until now.
PET/CT outperforms endoscopic ultrasound for esophageal cancer
January 26, 2015 -- Researchers from Nottingham, U.K., have found that PET/CT may be better than endoscopic ultrasound for accurately estimating tumor length in cases of esophageal cancer. PET/CT's enhanced performance in turn might lead to better planning of radiotherapy and resection.
MRI and PET tackle Alzheimer's diagnostics
January 8, 2015 -- A new window into the development of Alzheimer's disease may have been opened up by German researchers. They have combined two noninvasive imaging techniques to study b-amyloid plaques and found a connection between their formation in cerebral blood vessels and reduced blood flow in the brain.
