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.
