Prolonged CT lung screening offers cumulative benefits
April 15, 2019 -- The latest results from the Multicentric Italian Lung Detection trial highlighted the increasing benefits of CT lung screening over time -- starting after year five -- culminating in a 39% reduction in lung cancer mortality risk for eligible smokers at 10 years, according to a recent study published in the Annals of Oncology.  Discuss
Ultrasound CADx software can stratify thyroid nodules
April 15, 2019 -- Although it doesn't perform as well as a sonography expert, ultrasound computer-aided diagnosis (CADx) software can still be useful for stratifying thyroid nodules by their risk of malignancy, according to research published online April 11 in the American Journal of Roentgenology.  Discuss
Flortaucipir-PET shows promise for detecting CTE
April 12, 2019 -- Flortaucipir-PET scans revealed high amounts of tau protein in brain regions associated with chronic traumatic encephalopathy (CTE) in former professional football players, potentially enabling this disease to one day be diagnosed before death, according to new research in the New England Journal of Medicine.  Discuss

April 12, 2019 -- Yes, the emergency room can be a dangerous place for a physician. But even greater danger can be found elsewhere in the hospital, as we learn in the next installment of #MyRadGirlfriend.  Discuss
DBT boosts diagnosis of additional breast cancer
April 11, 2019 -- Adding digital breast tomosynthesis (DBT) to digital mammography boosts diagnostic accuracy for finding additional ipsilateral and contralateral breast cancer in women with nondense breast tissue, according to a study published online April 9 in Radiology.  Discuss
AIUM: Both thermal ablation methods work for thyroid
April 11, 2019 -- ORLANDO, FL - Both radiofrequency (RF) and microwave ablation are effective for treating benign thyroid nodules, offering patients an alternative to surgery, according to research presented at the American Institute of Ultrasound in Medicine (AIUM) meeting.  Discuss
MRI can help assess additional damage from ACL injuries
April 11, 2019 -- An acute anterior cruciate ligament (ACL) injury often also inflicts damage to the anterolateral structures of the knee. A preoperative MRI can help to assess these injuries and assist in surgical planning, according to a study published in the April issue of the American Journal of Sports Medicine.  Discuss
AIUM: TRUS or MRI for prostate diagnosis?
April 10, 2019 -- ORLANDO, FL - Although multiparametric MRI may be widely considered now as the go-to exam for detecting prostate cancer and guiding biopsies, transrectal ultrasound (TRUS) can still be a viable option, according to a presentation at the American Institute of Ultrasound in Medicine (AIUM) meeting.  Discuss
Low-energy scanning methods cut CT contrast dose
April 10, 2019 -- Using dual-energy CT or simply lowering the tube voltage of standard CT can enable a 25% reduction in contrast dose for CT exams without altering image quality -- uncovering the potential for hospital-wide cost savings, according to an article published online April 9 in Radiology.  Discuss
fMRI links imaging biomarker to PTSD treatment response
April 10, 2019 -- Using functional MRI (fMRI), researchers have observed abnormal patterns of brain activity in patients with post-traumatic stress disorder (PTSD) that can predict a poorer response to therapy, according to two studies published online April 3 in Science Translational Medicine.  Discuss
