DR chest tomosynthesis helps characterize lung lesions December 12, 2011 -- The use of chest tomosynthesis with a digital radiography (DR) system enabled radiologists to characterize pulmonary lesions, circumventing the need for further diagnostic workup of patients with CT, according to a study by Italian researchers.
iPad offers value in mobile emergency CT reading December 9, 2011 -- Although the experience provided by an iPad for reviewing medical images still has room for improvement, the popular tablet can be employed for remote reading of emergency CT studies by radiologists on the move, according to research presented at the RSNA 2011 meeting in Chicago.
DR chest tomo reduces number of CT exams in Sweden December 6, 2011 -- Using chest tomosynthesis with a digital radiography system reduced the number of chest CT exams performed at a Swedish institution, leading to lower radiation dose and better use of CT resources, according to a presentation from last week's RSNA meeting.
Same CCTA results mean different risks in men and women December 5, 2011 -- CHICAGO - Researchers have long known of differences between men and women in the rate of cardiac disease and resulting morbidity, but a new study presented at RSNA 2011 suggests that the same coronary CTA (CCTA) results require different interpretation and risk assessments depending on the patient's gender.
Repeat brachytherapy a viable option for prostate cancer December 2, 2011 -- CHICAGO - Prostate cancer patients who undergo brachytherapy treatments that fail due to inadequately placed radioactive seeds -- but who don't develop distant metastases -- may have better luck the second time around, concluded a study presented at the RSNA meeting.
Lossy image compression affects CAD performance December 1, 2011 -- CHICAGO - Although it doesn't influence 3D volume rendering, lossy image compression can negatively affect computer-aided detection (CAD) performance, according to research presented at the RSNA 2011 meeting.
An RSNA 'Christmas Carol' December 1, 2011 -- CHICAGO - For years, the PACSman Awards were an annual tradition in AuntMinnie.com's coverage of the RSNA conference. With the PACSman hanging up his typewriter last year, the baton has now passed to the Dalai Lama of PACS, radiologist and blogger Dr. Sam Friedman, who shares his unique RSNA experience.
Implementing meaningful use isn't a cakewalk yet December 1, 2011 -- CHICAGO - From a radiology perspective, meaningful use guidelines are challenging, with a minefield of unknowns and pitfalls. It's perhaps unsurprising, then, that a panel discussion on how radiology practices are actually handling meaningful use attracted quite a crowd on Tuesday at RSNA 2011.
PET/MRI surpasses PET/CT for some abdominal lesions December 1, 2011 -- CHICAGO - PET/MRI can outperform PET/CT for lesion conspicuity and characterization in the abdomen, particularly in the liver, according to a study presented by Swiss researchers at the RSNA 2011 meeting.
iPads are OK for VC reviews, but take longer November 30, 2011 -- CHICAGO - Apple's iPad 2 can be used safely and effectively for 2D reviews of virtual colonoscopy images, but using the device for this purpose takes longer and may require extra training, Italian radiologists reported at the RSNA 2011 meeting.
