MR attenuation correction for PET/MRI must consider bone factor
April 22, 2014 -- When it comes to standard MR attenuation correction for whole-body PET/MRI oncology scans, Danish researchers are advising users to account for bone attenuation to eliminate bias in tracer uptake of bony and soft-tissue lesions.
PET shows vegetative patients' chance for recovery
April 16, 2014 -- Belgian researchers have found that FDG-PET scans are more useful than functional MRI in identifying which severely brain damaged individuals in vegetative states have the potential to recover consciousness.
Profile of medical physicists looks set to rise sharply
April 15, 2014 -- The new European Union directive on the safety of ionizing radiation in medicine requires closer involvement of medical physics experts in radiology. This interview with Dr. Horst Lenzen discusses how this requirement can be met without placing excessive demands upon hospitals.
U.K. issues new guidance on cancer imaging
April 1, 2014 -- The U.K. Royal College of Radiologists (RCR) has published updated recommendations for cross-sectional imaging in cancer management. They can be downloaded free of charge from the RCR's website.
CT perfusion useful for evaluating small esophageal tumors
March 21, 2014 -- CT perfusion can be used to evaluate esophageal cancers with small tumor diameters that are not amenable to assessment with PET/CT, according to a new study by Turkish researchers presented at ECR 2014 earlier this month.
Study finds PET/CT can help diagnose CUP syndrome
March 10, 2014 -- VIENNA - FDG-PET/CT can identify a possible primary tumor in patients with carcinoma with unknown primary tumor (CUP) syndrome at a rate comparable to that found in autopsy studies, German researchers reported on Monday at ECR 2014.
Controversy breaks out over how to study cell death in cancer
March 9, 2014 -- VIENNA - When Dr. Uwe Haberkorn drew breath after his ECR presentation during a New Horizons session on imaging the hallmarks of cancer, he probably didn't anticipate the lively debate that was to follow.
Hybrid imaging gathers momentum in cardiac indications
March 6, 2014 -- VIENNA - Hybrid imaging is gaining acceptance as opportunities using combinations of modalities emerge and promise to optimize cardiac imaging, according to expert speakers in today's session called "Hybrid cardiovascular imaging: Where should we go?" at ECR 2014.
Ga-68 DOTATATE PET/CT detects neuroendocrine tumor recurrence
February 27, 2014 -- German researchers have confirmed the efficacy of PET/CT with the radiopharmaceutical gallium-68 (Ga-68) DOTATATE for detecting the recurrence of neuroendocrine tumors, in a study published in the February issue of Radiology.
FDG-PET/MRI shows advantages with malignant bone lesions
February 20, 2014 -- Compared with PET/CT, FDG-PET/MRI with a fully integrated whole-body scanner is "technically and clinically robust" in its evaluation of bone lesions, despite differences in attenuation correction between the two hybrid modalities, according to a German study in the February issue of the Journal of Nuclear Medicine.
PET/MRI: A good fit for brain imaging?
February 10, 2014 -- Simultaneous PET/MRI combines the sensitive molecular imaging of PET with soft-tissue contrast and functional information from MRI. A promising application for PET/MRI is quantitative brain studies, which demand high performance and stability from both modalities.
Online imager detects deformable motion
January 24, 2014 -- An online x-ray imaging system could provide 3D deformable motion tracking for use in scanned proton therapy, according to researchers at the Paul Scherrer Institute (PSI) in Villigen, Switzerland.
Swiss scoop top award for work on head and neck tumors
January 23, 2014 -- Researchers from Geneva collected a prestigious Magna Cum Laude award at the recent RSNA 2013 meeting in Chicago for their studies on diffusion-weighted imaging and PET/MRI. They were one of only five European groups who received the top prize for their education exhibits.
PET/MRI offers details in acute myocardial infarction cases
January 10, 2014 -- German researchers have concluded that simultaneous PET/MRI for patients with acute myocardial infarction is feasible after finding "good concordance" in a comparison of PET and MR images. The study was presented at last month's RSNA meeting in Chicago.
Focused ultrasound releases cancer drug
January 9, 2014 -- In a step toward the clinical use of ultrasound-mediated doxorubicin delivery, a joint French-Dutch research project has identified the ultrasound characteristics required to release the chemotherapy drug from temperature-sensitive liposomes.
From quantum physics to clinical device
December 24, 2013 -- A research project that began as a comparative investigation into stationary and moving atomic clocks has led to the development of a new type of cardiac imaging device. A presenter at the U.K. Institute of Physics' Medical Physics Group's recent Translational Techniques meeting described how a collaborative effort bridged the gap between the lab and the clinic.
