Molecular advances boost evaluation of cancer treatment response
March 7, 2013 -- VIENNA - Advances in molecular imaging promise to make it realistic to identify differences in response of cancer cells to a specific treatment, and this information will eventually be used to better adapt therapies to a patient's specific needs.
US elastography, contrast-enhanced mammography, MR spectroscopy: Which offers the most promise?
March 7, 2013 -- VIENNA - Mammography is an imperfect modality, so it makes sense that radiologists are on the lookout for something better, or at least something to supplement the technique. Thursday's refresher course covers functional imaging of the breast and goes into detail about ultrasound elastography, contrast-enhanced mammography, and MRI diffusion, perfusion, and spectroscopy, which may supplement mammography or replace it altogether.
What is 'molecular' in molecular imaging?
March 6, 2013 -- "Molecular" is a very fashionable adjective, and molecular imaging has become the battlefield of a turf war. Everybody now wants to be a molecular imaging warrior. The Maverinck investigates in his latest column.
Hybrid brain imaging technique adds temporal dimension
February 26, 2013 -- MRI/PET/electroencephalography hybrid scanning has been achieved for the first time by a group of researchers from Jülich in Germany, according to a recent article published online by the Journal of Magnetic Resonance, which describes the work being done and makes a case for multimodal imaging at 3 tesla and 9.4 tesla.
PET features provide boost for therapy response prediction
February 18, 2013 -- Textural variables derived from PET images reveal intratumor heterogeneity and may help predict a patient's response to chemotherapy. Researchers explored their associations with the clinical responses of breast cancer patients in a recent article published in Physics in Medicine and Biology.
Nanotechnology attracts attention at Valencia meeting
February 14, 2013 -- Nanotechnology in targeted imaging has been a central theme at the 14th Biennial Conference on Contrast-Enhanced Biomedical Imaging, held this week in Valencia, Spain. Concepts in nanotechnology for medical imaging used to focus on nanoparticles, but now it is moving from passive compounds to active compounds and nanodevices.
Molecular advances come under close scrutiny
February 13, 2013 -- The 14th Conference on Contrast Agents and Multimodal Cellular and Molecular Imaging begins in Valencia, Spain, today. Organized by the European Magnetic Resonance Forum and the Round Table Foundation, these biennial meetings are designed to promote scientific exchange and interaction among academic and industry researchers. The main organizer, Dr. Peter Rinck, PhD, speaks about the event.
Study shows PiB-PET detects amyloid plaque in heart
February 7, 2013 -- Swedish researchers are expanding the use of PET imaging with carbon-11-labeled Pittsburgh Compound B (PiB) to cardiac amyloidosis, confirming the biomarker's ability to detect amyloid plaque deposits in the heart in a first-of-its-kind study in the February issue of the Journal of Nuclear Medicine.
Arab Health: Is PET/MRI really worth the extra cost?
January 28, 2013 -- DUBAI - Most PET/MR systems cost between $5 million and $7 million U.S., whereas a new generation PET/CT machine with 128 detectors costs between $1.5 million and $2 million U.S. Is PET/MR worth the extra dollars, asks a global expert on hybrid imaging at Arab Health.
Biomarkers require urgent standardization to succeed in oncology
January 28, 2013 -- To be effective in clinical practice, functional and molecular imaging biomarkers in oncology require a stable platform, broad availability, readily specifiable acquisition parameters, standardized interpretation, and a defined reproducibility that has been documented in many cancers and normal ranges.
C-11 choline PET/MRI helps restage prostate cancer patients
January 17, 2013 -- A preliminary study by German researchers suggests that carbon-11 (C-11) choline PET/MRI may provide an alternative imaging modality to PET/CT for restaging of prostate cancer by offering equal, if not better, diagnostic performance and less radiation exposure.
Brachytherapy dose calculation just got better
January 15, 2013 -- Everyone agrees that patients undergoing radiotherapy usually do not resemble uniform water spheres with a 30-cm diameter. Nevertheless, this is the common assumption of radiation dose calculations used for brachytherapy.
Spatial resolution model enhances PET imaging of various cancers
January 8, 2013 -- Using routine clinical protocols in whole-body FDG-PET/CT, Danish researchers have found that a point spread function PET reconstruction technique increases lesion detection for numerous cancers, according to an article in the European Journal of Radiology.
Moving to the dark side: Personalized medicine revisited
January 7, 2013 -- Swimming with the scientific tide doesn't necessarily mean clinging to progress. In his latest column, Dr. Peter Rinck revisits the topic of personalized medicine, taking a short look back in medicine's history.
Leiden debate focuses attention on future of imaging markers
December 10, 2012 -- Hundreds of promising target molecules have been identified in preclinical studies for possible use as novel cell imaging agents. But how many are ever likely to be used in real patients? And who will pay the costs of the clinical trials needed to prove their value?
