Arab Health: Why CT really can rule supreme in coronaries
January 26, 2015 -- DUBAI - CT is now the gold standard for ruling out coronary artery stenoses and coronary anomalies. It can also be useful for coronary artery bypass graft and electrophysiology studies, as well as investigations of pulmonary veins, delegates learned on the opening day of Arab Health.
PET/CT outperforms endoscopic ultrasound for esophageal cancer
January 26, 2015 -- Researchers from Nottingham, U.K., have found that PET/CT may be better than endoscopic ultrasound for accurately estimating tumor length in cases of esophageal cancer. PET/CT's enhanced performance in turn might lead to better planning of radiotherapy and resection.
CT yields lower calcium scores in obese patients
January 23, 2015 -- Coronary artery calcium scores are underestimated significantly in larger patients compared with smaller ones -- enough to potentially alter their risk stratification, according to researchers from the Netherlands.
What do patients really know about radiation and radiologists?
January 22, 2015 -- While it's all well and good for radiologists to spend more time interacting with patients, it's important to understand what patients actually know about radiation and radiologists to do this effectively. Two studies presented at the recent RSNA meeting explored these questions and came to some surprising conclusions.
Irish learn lessons from national PACS project
January 21, 2015 -- Achieving a fully integrated national RIS/PACS network using a single archive is a hugely challenging task, but it can be achieved with adequate resources and close cooperation between medical disciplines, according to researchers from the Republic of Ireland.
Spectral imaging with DSCT edges out multienergy CT
January 21, 2015 -- In a world of multiple emerging spectral CT technologies, it's impossible to know which competing method will ultimately deliver the best image for the dose. But right now dual-source CT (DSCT) edges out the others, say German researchers.
Wavelet algorithm transforms cerebral CT angiography
January 20, 2015 -- Visualization of cerebral vessels at CT angiography can be vastly improved with the use of a novel technique called wavelet transform, which boosts signal-to-noise ratios as much as ninefold in 3D datasets and improves image quality overall, according to German researchers.
Keep aware of pitfalls in abdominal radiography
January 19, 2015 -- What must you do when you find a calcified lesion on an abdominal x-ray? To answer a tricky question like this, it's vital to learn how and when to diagnose calcified lesions on plain film and to know when another examination is required, say Spanish radiologists.
Large-nodule lung CAD shows high accuracy
January 19, 2015 -- Researchers in the Netherlands have developed a new computer-aided detection (CAD) scheme that can pick up large pulmonary nodules at thoracic CT, plugging a disappointing gap in current CAD technology.
Wireless mobile DR gets images into PACS faster than CR
January 16, 2015 -- Researchers from Hong Kong were able to obtain mobile x-ray images in their PACS network 70% sooner using a wireless portable digital radiography (DR) unit rather than a mobile x-ray system equipped with computed radiography (CR) plates, according to a January 6 article in the Journal of Digital Imaging.
iPads are sufficient to diagnose spine fractures
January 15, 2015 -- Radiologists can make use of iPads to diagnose thoracolumbar spine fractures on radiographs, performing just as well as they would on traditional PACS diagnostic workstations, Greek researchers reported at the recent RSNA meeting in Chicago.
BJR: New approach on patient reference dose is vital
January 14, 2015 -- Using diagnostic reference levels has outlived its usefulness, according to an article by radiation protection expert Dr. Madan Rehani, PhD, in the British Journal of Radiology (BJR). Instead, hospitals should adapt acceptable quality dose for their own needs.
