Why expert speakers so often disappoint us
October 16, 2013 -- Disappointing lectures by noted experts abound. The reasons vary, but a mild anticlimax is commonplace. Dr. Paul McCoubrie shares in his latest column the reason that is the case: Often the speaker doesn't know how to simplify his or her presentation.
Unveiled: 10-point plan of action for managing dose
October 15, 2013 -- The European Society of Radiology has revealed its latest thinking and strategy for radiation protection. It wants greater use to be made of CT dose recording and dose repositories, and is launching a campaign at ECR 2014 in March.
World expert on soft-tissue tumors, Arthur De Schepper, dies
October 14, 2013 -- Dr. Arthur De Schepper was a greatly admired radiologist. He was a world authority on soft-tissue tumors, created the "Antwerp school of radiology" in Belgium, and wrote hundreds of poems. Two colleagues, Drs. Paul Parizel and Jan Bosmans, pay tribute to him.
Lancet: Angiography busts theory of venous link to MS
October 14, 2013 -- Countering prior findings that cerebrospinal venous narrowing and multiple sclerosis (MS) go hand in hand, a study incorporating both x-ray venography and ultrasound found that venous narrowing is unrelated to MS. The new results were published online on 9 October in Lancet.
Brain stones: Between a rock and a hard place?
October 9, 2013 -- Brain stones -- large solid intracranial calcifications -- are more common than previously thought, and while MRI sequences can be useful adjuncts, CT is now the mainstay in identifying and characterizing these intriguing items, Belgian researchers have asserted.
Bone suppression tool can cut missed pulmonary nodules
October 3, 2013 -- Bone suppression computer-aided detection software can provide a significant boost for diagnosis of pulmonary nodules, especially those of moderate and subtle conspicuity, Dutch researchers have reported.
International Day of Radiology focuses on thoracic imaging
October 1, 2013 -- The vital role played by imaging in the detection, diagnosis, and management of lung diseases will be the prime focus of the 2013 International Day of Radiology, which will take place on 8 November. Also, more patient groups will participate in this year's event.
JFR: Imaging must combat social inequalities of cancer care
September 25, 2013 -- Cancer imaging will come under the spotlight during next month's Journées Françaises de Radiologie Diagnostique et Interventionnelle (JFR) in Paris, but controversy persists over the inequality to prevention, screening, and shortage of MRI units.
Why we should preserve eponyms
September 18, 2013 -- Classic signs such as "bat's wing appearance" or "mushroom sign" are well-accepted in radiology, but eponyms tend to be less widely used. Dr. Paul McCoubrie thinks this is a real shame and is leading the campaign to save the eponym.
Global x-ray equipment market reaches 7.5B euros
August 22, 2013 -- Driven by continued digitization of x-ray systems and increasing healthcare investments in emerging regions, the global market for x-ray equipment reached 7.5 billion euros ($10 billion) in revenue in 2012 and is expected to increase by 18% to reach 9 billion euros ($12 billion) in 2017, according to market research firm IMS Research.
Why all the hype about retrofit flat-panel detectors?
August 22, 2013 -- The retrofit flat-panel detector market accounted for around 3% of general radiography x-ray unit shipments in Europe, the Middle East, and Africa in 2012, and the figure is forecast to increase to 5% by 2017. We look at what's driving the market and analyze the key trends.
Study: Too few clinicians give chest x-ray details on CT requests
August 22, 2013 -- Emergency teams are particularly poor at documenting chest x-ray findings on request forms for CT, but when details are included, there is usually good correlation between accident and emergency departments and radiology reports, according to an audit reported at the 2013 U.K. Radiological Congress.
Röntgen, Edison, et al: Early days of x-ray revisited
August 12, 2013 -- When W.C. Röntgen discovered x-rays in 1895, he observed their effect on photographic glass and fluorescent salts. Only after Thomas Edison developed the cryptoscope did the technology become useful for looking at the chest and thicker parts of the body, writes history columnist Dr. Adrian Thomas.
MRI rules supreme on elbow pain at London Olympics
August 7, 2013 -- It's official: MRI was the overwhelming winner when it came to elbow investigations on competitors at the 2012 Olympic Games. Also, most elbow injuries occurred in power and combat sports such as judo, boxing, wrestling, and weightlifting, according to one of the first peer-reviewed, scientific articles about the games.
Le Tour de France: Imaging cycling's elite
August 7, 2013 -- For the first time, cyclists at this year's Tour de France benefited from a mobile medical and imaging unit that allowed doctors to diagnose and treat participants quickly. In total, 40 cyclists and 50 volunteer helpers underwent imaging during the arduous three-week event in July.
Photon counting can assist in energy-resolved imaging
August 5, 2013 -- Photon-counting detectors based on cadmium telluride and cadmium zinc telluride offer many advantages for x-ray imaging. Their energy discriminating properties improve material decomposition, eliminate electronic noise, and can reduce patient dose, but detectors are hindered by a limited count rate relative to the photon flux.
