CT speeds antiangiogenesis therapy assessment
June 14, 2010 -- CT perfusion imaging can spot significant changes in blood flow and volume soon after administration of antiangiogenic therapy, researchers from Munich, Germany, report in a new animal study. Faster assessment can lead to nimbler, more flexible cancer care compared to traditional tumor size measurements.
F-18 NaF PET/CT can help with atherosclerotic plaque detection
June 11, 2010 -- German researchers have found that F-18 sodium fluoride (F-18 NaF) PET/CT may provide "relevant information about the morphologic and functional properties of calcified plaque," according to a study published in the June issue of the Journal of Nuclear Medicine.
PET/CT may improve therapy for congestive heart failure patients
June 7, 2010 -- SALT LAKE CITY - German researchers have found that FDG-PET/CT can help determine when cardiac resynchronization therapy is ineffective, and it can identify risk factors that could alter the course of treatment for patients with congestive heart failure, according to a study presented Sunday at the SNM meeting.
Dual-energy VC aims for noninvasive polyp evaluation
June 2, 2010 -- Dual-energy CT may find itself forging a new path in virtual colonoscopy by not only finding colorectal lesions but characterizing them in ways other noninvasive techniques cannot, according to a presentation at the International Society for Computed Tomography conference.
Nonlaxative PET/CT colonography is both feasible and effective
May 27, 2010 -- For individuals who need a highly accurate colon screening exam but can't tolerate a full bowel prep, nonlaxative PET/CT colonography may be just what the doctor ordered, according to a new study from the U.K. published this month in the Journal of Nuclear Medicine.
Optical imaging deciphers truth within oil painting layers
May 26, 2010 -- How can the hidden past of artwork be revealed without damaging the creation itself? Since 2003, researchers in Poland have been looking to optical coherence tomography for answers, using the technology to detect suspected forgeries in paintings and unearth hidden inscriptions, among other applications.
Gadobenate better than gadopentetate contrast in MRA
May 24, 2010 -- Gadobenate dimeglumine offers better performance than gadopentetate dimeglumine in patients undergoing contrast-enhanced MR angiography (MRA) for suspected peripheral arterial occlusive disease, according to a study in the June issue of Radiology.
New software facilitates mining of image data
May 24, 2010 -- Images stored on PACS networks contain a veritable treasure trove of information that could be invaluable in research and clinical practice. To gain easier access to those nuggets, researchers from Luxembourg have developed a software framework that facilitates data mining from DICOM image headers.
U.K. oncology center learns lessons with tomotherapy adoption
May 18, 2010 -- How does a busy radiation oncology department adopt and implement a new treatment technology with which it has no prior experience? Through careful planning, effective teamwork, and ample time allocated for training and development of a rigorous quality assurance program.
CR-based digital mammography beats analog for screening
May 11, 2010 -- In the push to convert to digital mammography, many facilities are using computed radiography (CR)-based systems as an interim step. But just how well does CR mammography compare to traditional analog imaging in a screening environment?
