Time to ditch the chest x-ray, researchers conclude
November 29, 2012 -- CHICAGO - If cost isn't an issue -- and that's a big if -- it's time to say goodbye to chest radiography, say researchers from Norway who compared chest x-ray to ultralow-dose CT. Results were presented on Thursday at the 2012 RSNA meeting.
Low-dose mammo, wireless US probe, 3T MRI pace Siemens at RSNA
November 28, 2012 -- CHICAGO - A new digital mammography system with lower radiation dose, a wireless ultrasound probe, a 3-tesla MRI scanner designed for high-performance clinical and research work, and a new line of angiography systems are among the highlights in the RSNA 2012 booth of Siemens Healthcare.
Radiologists should eye scans for clues to elder abuse
November 28, 2012 -- CHICAGO - The under-the-radar problem of physical abuse of the elderly can be countered by radiologists who observe certain patterns of head and neck injuries, subdural hematomas, and the social context surrounding these cases, researchers reported at RSNA 2012.
CT dose reduction, PET/MRI pace Philips RSNA news
November 28, 2012 -- CHICAGO - New developments in CT dose reduction, an expansion of its digital MRI architecture, and new enhancements in PET/MRI are pacing product news in the RSNA 2012 booth of Philips Healthcare.
Residents need twice the fluoro time to place catheters
November 27, 2012 -- CHICAGO - Radiology residents at two large teaching hospitals in Tennessee required twice as long as interventional radiologists to place central venous catheters under fluoroscopy guidance, effectively doubling the radiation dose to the patient, according to a study presented at the 2012 RSNA meeting.
CT can replace x-ray for pediatric cystic fibrosis patients
November 27, 2012 -- CHICAGO - Ultralow-dose CT is on par with a frontal chest x-ray in terms of dose (0.05 mSv) and gives an accurate diagnosis in pediatric cystic fibrosis patients, Belgian researchers revealed on Monday afternoon at the annual RSNA meeting.
Toshiba's RSNA highlights include new 320-row CT scanner
November 26, 2012 -- CHICAGO - A new flagship 320-detector-row CT scanner, a price drop for its 1.5-telsa MRI scanner, and new technologies in ultrasound and wireless digital x-ray are among the highlights in the RSNA 2012 booth of Toshiba America Medical Systems.
Siemens to launch new Artis Q angio line at RSNA
November 19, 2012 -- Siemens Healthcare is planning to launch a new line of premium angiography systems, called Artis Q, at the upcoming RSNA meeting in Chicago. The new line includes enhancements in detector design, guidance technology, and x-ray tube instrumentation.
CBCT-like angio predicts TACE response a month before MRI
November 13, 2012 -- A dual-phase angiography procedure based on conebeam CT (CBCT) principles that was used during transcatheter arterial chemoembolization (TACE) can predict treatment response in hepatocellular carcinoma tumors long before MRI is traditionally applied at one-month follow-up, researchers wrote in Radiology.
Moments in Radiology History: Part 8 -- Imaging of black lung
October 15, 2012 -- In 1969, the U.S. Congress passed a new piece of legislation on coal mining that called for compensation to miners who had developed pneumoconiosis, or black lung. The new program relied heavily on medical imaging to detect the disease, with radiology playing a major role in the program's implementation.
Image Gently expands dose reduction campaign to digital x-ray
September 18, 2012 -- The Image Gently radiation dose reduction campaign has launched a new initiative targeting the most common imaging exam of all: radiography. The group's new Back to Basics initiative, launched today, is intended to strengthen radiation protection in children as radiography shifts from analog film to digital x-ray.
NICU staff may be exposed to radiation during pediatric x-rays
August 30, 2012 -- Adult fingers from neonatal intensive care unit (NICU) staff were visualized on nearly half of x-ray images acquired at a Canadian hospital, and, in some cases, nurses might not be aware of their inadvertent radiation exposure, researchers have found.
Radiologists vary DR image quality to optimize radiation dose
August 24, 2012 -- A new Chinese study questions the assumption that striving for the highest possible image quality is always the best approach. Researchers developed an x-ray optimization strategy that cuts the dose of digital radiography (DR) substantially by adjusting dose levels based on the type of exam being conducted.
HCA slammed for unnecessary cath procedures
August 7, 2012 -- The largest for-profit hospital chain in the U.S. is under fire for performing thousands of cardiac catheterization procedures that were medically unnecessary, according to an August 6 article in the New York Times.
Cardiac cath technologist charged in hepatitis C infections
July 24, 2012 -- Federal authorities in New Hampshire have charged a traveling cardiac cath technologist with infecting patients with hepatitis C after he allegedly stole syringes containing fentanyl and replaced the dirty needles with saline solution. The case has authorities fearing an outbreak of hepatitis C in more than half a dozen states.
Moments in Radiology History: Part 5 -- Bullets and bones
May 29, 2012 -- "Bullets, bones, and kidney stones" was a phrase that sprung up in the earliest months of the medical use of x-rays. Just as Wilhelm Conrad Röntgen had noticed that x-rays showed bones minus normal flesh, young surgeons found that the images could show them where surgery could correct problems.
Moments in Radiology History: Part 4 -- Discovering x-rays
May 18, 2012 -- From PET/CT to pocket-sized ultrasound, radiologists seem to have an unlimited array of powerful medical imaging tools at their disposal. But the roots of the discipline are far more elementary, grounded in a serendipitous finding that occurred in a laboratory in Germany, as noted by radiology historian Otha Linton.
Heart societies issue new guidelines on cardiac cath
May 10, 2012 -- A report issued on Wednesday by the American College of Cardiology Foundation and several other medical societies offers detailed criteria for determining when invasive cardiac catheterization is a reasonable option for evaluating patients for heart disease.
Moments in Radiology History: Part 3 -- X-ray's early martyrs
April 12, 2012 -- How do you make sure a fluoroscope is warmed up? How about putting your hand in front of it until your finger bones appear? That's how early physicians approached the new x-rays discovered by Wilhelm Conrad Roentgen. Many of these doctors became radiology's first martyrs.
Study links frequent dental x-rays with brain tumors
April 10, 2012 -- People who have received frequent dental x-rays have an increased risk of developing meningioma, according to a case-control study examining the correlation between dental x-rays and meningioma. The findings support the need for practitioners to exercise their best professional judgment when determining whether an imaging study is a diagnostic necessity.
