fMRI reveals that 'magic mushrooms' reduce depression
October 13, 2017 -- U.K. researchers used functional MRI (fMRI) to determine that the psychoactive ingredient in "magic mushrooms" -- psilocybin -- decreases symptoms of depression, according to a study published online October 13 in Scientific Reports.  Discuss
AI algorithm predicts lung disease, adverse events on CT
October 13, 2017 -- Recent studies have demonstrated the power of artificial intelligence (AI) software to detect disease, but how well can it predict future adverse events? The extent to which AI can assess smokers' risk for lung disease on CT was reported in a new study published in the American Journal of Respiratory and Critical Care Medicine.  Discuss
Biomarker test could direct MRI use for prostate cancer
October 13, 2017 -- Dutch researchers are reporting promising results using a new urinary biomarker risk-scoring system to test for the possibility of prostate cancer. The test could be used to select which patients should be sent on for additional MRI scans or biopsy, according to a study published in the October issue of The Prostate.  Discuss

4D ultrasound contrast HSG assesses fallopian tubes
October 12, 2017 -- Hysterosalpingography (HSG) with 4D contrast ultrasound offers a less invasive option than laparoscopic chromopertubation for assessing the patency of fallopian tube fimbria, according to a study published in the October issue of the Journal of Ultrasound in Medicine.  Discuss
How augmented reality can transform medical imaging
October 12, 2017 -- Moving from lightboxes and x-ray film to 3D holographic images of patient anatomy, radiology has experienced incredible technological advances in recent years. And there's more to come: Pediatric radiologist Dr. Jesse Courtier believes the specialty is on the cusp of yet another exponential transformation.  Discuss
PET study links menopausal status to Alzheimer's
October 12, 2017 -- Could menopausal status be a factor in why women are more frequently afflicted with Alzheimer's disease than men? Using PET scans, researchers at Weill Cornell Medicine and the University of Arizona Health Sciences may have found a connection. Results of their study were published online October 10 in PLOS One.  Discuss

October 11, 2017 -- Wasted time represents a third of the total MRI exam process cycle -- and it can also extend a patient's length of stay in the hospital, according to research published in the October issue of the American Journal of Roentgenology.  Discuss
Right heart quantification awareness: Part 5
October 11, 2017 -- The right heart has jokingly been referred to as the organ's stepchild, with little attention paid to its size, function, and prognostic implications. In this column, Judith Buckland of CardioServ reviews the proper methods to quantify the right heart for both size and function on echocardiography.  Discuss
NIH opens massive x-ray database to propel AI research
October 10, 2017 -- Optimizing artificial intelligence (AI) algorithms for medical applications demands immense stores of imaging data. Researchers may now begin sating that need thanks to an enormous database of chest x-rays recently made available by the U.S. National Institutes of Health (NIH).  Discuss
