PET/CT outperforms endoscopic ultrasound for esophageal cancer
January 26, 2015 -- British researchers have found that PET/CT may be better than endoscopic ultrasound for accurately estimating tumor length in cases of esophageal cancer cases. 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.
FEC-PET/CT boosts cervical and endometrial diagnoses
December 11, 2014 -- PET/CT with the radioisotope F-18 fluoroethylcholine (FEC) is a feasible and promising imaging alternative to FDG-PET/CT in detecting cervical and endometrial tumors, according to a pilot study from the U.K. presented last week at RSNA 2014.
PET/MRI matches PET/CT in NSCLC accuracy
December 8, 2014 -- CHICAGO - Using a 15-minute MRI protocol with PET/MR, Swiss researchers achieved diagnostic accuracy equal to that of PET/CT for patients with non-small cell lung cancer (NSCLC). Study results were presented at last week's RSNA 2014 conference.
DWI adds little to PET/MRI for female pelvic malignancies
December 2, 2014 -- CHICAGO - Adding diffusion-weighted imaging (DWI) to FDG-PET/MRI to stage women with primary or recurrent pelvic malignancies contributes minimal value and is not worth the additional scan time, according to a study from Germany presented on Sunday at RSNA 2014.
Dutch group strives to simplify PET/CT
November 28, 2014 -- Researchers in the Netherlands have created an easy-to-use image processing tool that provides clinicians with a fast and accurate way to derive organ absorbed dose and effective dose estimates in PET/CT. They aim to avoid the need for manual volumes-of-interest delineation.
Multifunctional microbubble agents display clinical promise
November 21, 2014 -- Multifunctional microbubble agents are showing great potential for medical applications, particularly superparamagnetic iron oxide nanoparticles, which are used as MRI contrast agents but can be combined with encapsulated microbubbles and provide ultrasound contrast.
Tread carefully on lung cancer screening, U.K. experts urge
November 18, 2014 -- For effective implementation of lung cancer screening, start with a program targeting those most at risk and employ pathways minimizing risk of harm, including those due to overdiagnosis, and then expand as unanswered issues are clarified, U.K. specialists have advocated.
Meeting the challenge of imaging the head and neck
November 17, 2014 -- Today's head and neck radiologists play a key role guiding examinations and reporting them. Dr. Florian Dammann, chair of the German Radiological Society's Head and Neck Diagnostics Working Group, explains more about the subspecialty in this interview.
How a British boy band changed imaging forever
November 10, 2014 -- LONDON - What do circus tricks and a top British boy band have in common? Both had a major impact on the development of imaging during the second half of the 20th century, Dr. Stavros Stivaros, PhD, told the audience at last week's U.K. Royal College of Radiologists annual public lecture.
