Radiation dose safety: Filtering the message from the noise
April 18, 2014 -- Patient radiation dose safety is a hot topic in the imaging industry and media. But as often happens when a subject is hot, the radiation safety information pool has become muddied with disparate and conflicting information. Neil Singh from Ascendian Healthcare Consulting helps filter the true message in radiation safety from the industry noise.
MRI finds loss of brain volume in older, apathetic adults
April 17, 2014 -- MRI scans have revealed that older adults with bouts of apathy may have smaller volumes of gray and white matter in areas of the brain associated with learning, memory, and internal communication, according to a study published online April 16 in Neurology.
Lung cancer screening reduces mortality in COPD patients
April 17, 2014 -- Lung cancer screening with CT and spirometry delivers a high rate of diagnosis of early-stage lung cancers and reduces mortality in individuals with mild to moderate chronic obstructive pulmonary disease (COPD), according to a pilot study in Respiratory Medicine.
Swiss board repeats call to abolish breast screening
April 16, 2014 -- Breast cancer screening programs in Switzerland should be wound down, as screening does not clearly produce more benefits than harms, according to an editorial by two members of the Swiss Medical Board published in the New England Journal of Medicine.
ACR, SBI take issue with Swiss NEJM commentary
April 16, 2014 -- The American College of Radiology (ACR) and Society of Breast Imaging (SBI) have issued a joint statement strongly criticizing an article published on Wednesday in the New England Journal of Medicine that takes aim at breast cancer screening programs in Switzerland.
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.
Digital mammography finds DCIS most likely to become cancer
April 16, 2014 -- Digital mammography finds more small, invasive breast cancers, but it also identifies more ductal carcinoma in situ (DCIS) -- some of which may never cause harm if undetected. But a new study in the April issue of Radiology claims that digital mammography tends to find DCIS lesions that are more likely to progress to cancer.
DTI-MRI sheds light on mild traumatic brain injury
April 15, 2014 -- Researchers using diffusion-tensor MRI (DTI-MRI) believe they have identified parts of the brain that cause people with mild traumatic brain injury to become dizzy or have vision problems, according to a study published online April 15 in Radiology.
PET/CT details hint at survival of head and neck cancer patients
April 15, 2014 -- Japanese researchers have found that several PET/CT parameters -- in particular, a ring-shaped area of FDG uptake -- are reliable predictors of survival for patients with head and neck squamous cell carcinoma. Results of their study were published in the April issue of the American Journal of Roentgenology.
