Analysis: CT lung cancer screening won't break the bank May 15, 2015 -- The costs of population-wide CT lung cancer screening are likely to be reasonable and comparable to the costs of breast or colon cancer screening, according to an article in the May edition of Thoracic Surgery Clinics.
CTA protocol slashes radiation dose tenfold in aortic disease May 11, 2015 -- A novel CT angiography (CTA) technique using nongated high-pitch images and iterative reconstruction delivered diagnostic scans across the board at about one-tenth the dose of standard exams, along with fewer motion artifacts and lower contrast media requirements, concludes a new study in Academic Radiology.
Rads are doing fewer double CT scans -- but nonrads aren't May 8, 2015 -- The U.S. Centers for Medicare and Medicaid Services has worked to cut imaging costs across all modalities, and its efforts with "double" CT scans of the abdomen have been effective with radiologists, who have reduced their rates by 35% since 2001. But other physicians haven't followed suit.
New CT-based liver segmentation tool proves fast and accurate May 6, 2015 -- Liver segmentation, used to obtain liver volumes when planning for major interventions, can be automated without loss of accuracy compared to manual measurements, cutting procedure time by more than half, according to a new study in Academic Radiology.
Mobile App Spotlight: CT Anatomy May 5, 2015 -- AuntMinnie.com presents the next article in an ongoing series highlighting notable mobile apps in radiology. In this installment, we take a look at CT Anatomy, an iOS app that offers a cross-sectional guide of normal anatomy as seen on CT.
CT reveals cardioembolic stroke that echo misses May 1, 2015 -- Echocardiography may be the de facto gold standard for cardiac evaluation of patients suspected of having cardioembolic stroke, but it isn't necessarily the best modality. A new study from Saudi Arabia used CT to discover several thrombi that echo had missed, along with other conditions.
No cost difference between CTC, colonoscopy in elderly April 30, 2015 -- A new analysis of Medicare data has found that after adjusting for patient demographic factors, costs are pretty much the same in the year following an initial screening exam for colorectal cancer, regardless of whether CT colonography (CTC) or optical colonoscopy is used, according to a report in Academic Radiology.
Safety-net hospital lifts the lid on child abuse April 29, 2015 -- Fresh data about suspected cases of abuse show that about a quarter of children evaluated at an inner city hospital by means of a skeletal survey with radiography were found to be the victims of abuse. Furthermore, of the abused children, around 39% had skeletal trauma and 61% did not.
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.
