American Journal Of Roentgenology Reviews Vaping-Associated Lung Injury Findings
An ahead-of-print "Clinical Perspective" article in the March issue of the American Journal of Roentgenology (AJR) summarizing the literature to date details common imaging manifestations of electronic nicotine delivery systems (ENDS)--including e-cigarettes and vaporizers, vape and hookah pens, as well as tank systems.
Because there is not a "standardized case definition for vaping-associated lung injury," wrote lead author Travis S. Henry from the University of California San Francisco, "the diagnosis of lung injury due to vaping may be made by establishing a temporal relationship between change in vaping habits and onset of lung disease, exclusion of other causes of lung disease (e.g., infection, other drug or exposure, connective tissue disease, and so on), and stabilization or improvement with cessation of vaping and possibly with corticosteroid treatment."

Finding Upends Theory About The Cerebellum’s Role In Reading And Dyslexia
New brain imaging research debunks a controversial theory about dyslexia that can impact how it is sometimes treated, Georgetown University Medical Center neuroscientists say.
The cerebellum, a brain structure traditionally considered to be involved in motor function, has been implicated in the reading disability known as developmental dyslexia. However, this “cerebellar deficit hypothesis” has always been controversial.
The new research shows that the cerebellum is not engaged during reading in typical readers and does not differ in children who have dyslexia. That finding comes from a new study involving children with and without dyslexia published October 9, 2019, in the journal Human Brain Mapping.
It is well established that dyslexia, a common learning disability, involves a weakness in understanding the mapping of sounds in spoken words to their written counterparts, a process

PET Offers More Precise Screening Method To Select Candidates For Radionuclide Therapy
A new study published in The Journal of Nuclear Medicine evaluated the role of 68Ga-DOTATATE positron emission tomography/computed tomography (PET/CT) in selecting neuroendocrine tumor patients who may benefit from peptide receptor radionuclide therapy (PRRT). Although historically guided by a Krenning score based on 111In-pentetreotide scintigraphy, researchers found that Krenning scores based on PET/CT imaging were significantly higher and could more accurately detect patients eligible for PRRT. This is particularly relevant for patients with lesions of less than two centimeters, as the study showed that Krenning scores for these small-volume tumors were markedly higher when informed by PET/CT compared to 111In-pentetreotide scintigraphy and could qualify the patients for PRRT when they would otherwise have been ineligible.
"In the past, physicians relied on 111In-pentetreotide imagin

3D Mammograms: Are They Worth It?
If it's October, it's Breast Cancer Awareness Month, when pink ribbons sprout up on everything from suit lapels to yogurt containers, reminding women to turn their attention to breast health -- especially mammograms.
As 3D mammography, also called digital breast tomosynthesis, has become more available nationwide, a big question many women face is whether they should step up and get one. Are they safe, more effective and for every woman?
The answers are yes, yes and yes, said Cynthia A. Litwer, MD, chief of breast imaging at Cedars-Sinai.
"I recommend 3D mammograms for all women," the breast radiologist said. "They pick up more cancers because they're not obscured by dense breast tissue. That is true for all women, of all ages and all levels of breast density."
Litwer sat down with Cedars-Sinai's Newsroom to address the benefits of 3D mammography.
