ARRS: 6 reasons to be optimistic about radiology April 27, 2015 -- Radiologists love to complain about the challenges they face, including declining reimbursements, a tight job market, and increased workload. But there are at least six good reasons to be optimistic about the specialty, according to a presentation at the American Roentgen Ray Society (ARRS) annual meeting in Toronto.
Motion-tracking MRI gives new insight into stroke risk April 27, 2015 -- Using a novel motion-tracking MRI technique, researchers from Johns Hopkins University have uncovered new evidence that reduced function in the left atrium of the heart may be a sign of increased stroke risk in patients with or without atrial fibrillation.
Bedside ultrasound can diagnose acute shoulder dislocation April 24, 2015 -- Patients presenting to the emergency department with acute shoulder pain typically receive an x-ray exam. However, ultrasound can provide equivalent performance -- often in less time and without the ionizing radiation -- for diagnosing shoulder dislocation, according to researchers from the University of California, Irvine.
ARRS: MR tractography touted as 'reliable' imaging biomarker April 24, 2015 -- Diffusion-tensor MR tractography may be a reliable quantitative imaging biomarker for assessing prostate cancer treatment response to androgen deprivation and radiation therapy, according to a study presented at the American Roentgen Ray Society (ARRS) meeting in Toronto.
LevelCheck algorithm targets wrong-site spinal surgery April 23, 2015 -- A new algorithm called LevelCheck -- designed to prevent wrong-site spinal surgery -- boasted near-perfect accuracy in a trial by Johns Hopkins University researchers. By matching preoperative CT scans to intraoperative radiographs, LevelCheck confirms for surgeons that they are targeting the correct vertebral level.
NEJM: PET for Hodgkin's lymphoma prevents unnecessary radiotherapy April 23, 2015 -- A negative PET scan immediately after three cycles of chemotherapy for early-stage Hodgkin's lymphoma can identify patients with an excellent prognosis and avoid unnecessary additional radiation therapy, according to a U.K. study published on 23 April in the New England Journal of Medicine.
IHS: Hospital overcrowding spurs medical opportunities in China April 23, 2015 -- The rapid expansion of healthcare spending in China has led to improved healthcare facilities and increased patient access. As a result, pressure on large metropolitan hospitals has intensified, and overcrowding is now increasingly common in large hospitals, according to a research brief by industry analyst Benjamin Niu of IHS.
Clinical decision support can cut inappropriate imaging April 22, 2015 -- A meta-analysis published on Tuesday in the Annals of Internal Medicine found that clinical decision-support (CDS) software can have a positive -- if moderate -- effect on appropriate ordering of imaging studies. The researchers stopped short of recommending the use of CDS, however.
ARRS: Sharing info leads to dramatic CT dose reduction April 22, 2015 -- TORONTO - Reducing unnecessary variation in CT radiation dose can be done fairly easily by getting radiology professionals together to share best practices, even across a healthcare system as large as the University of California's, according to a presentation at the annual American Roentgen Ray Society (ARRS) meeting.
