'Instant replay' fluoroscopy cuts radiation dose in children

By Eric Barnes

If you've ever watched a fluoroscopy study fly by and muttered something less printable than "Wait -- what was that again?" you may not be alone. Considering how fast physiologic processes happen, a little instant-replay action could go a long way toward nailing the diagnosis. Now researchers from Israel have found that a software feature known as last fluoroscopy hold (LFH) can dramatically reduce the need for another pass at the patient, thereby reducing the radiation dose and saving time.

Last fluoroscopy hold allows the radiologist to replay fluoroscopy sequences to get a second look without re-exposing the patient, thereby reducing dose and saving time. This video shows an upper GI barium series in a patient postgastric banding. There is a narrowing just beyond the ring that can be seen only for a split second, and then is hidden from view due to barium filling the rest of the stomach. Although this study was performed in a young adult and not a young child, it superbly depicts the "instant replay" benefit of last fluoroscopy hold.

Calcium scoring, CTA combine for better diagnosis of coronary artery disease

By Wayne Forrest

Acute chest pain is the most common symptom among emergency room patients. With quick diagnosis and treatment of these patients paramount, researchers from Germany studied whether a combination of coronary calcium scoring and CT angiography (CTA) could effectively and accurately diagnose patients with coronary artery disease, and reduce the number of nonevaluable examinations.

French firm Biospace Med prepares for launch of EOS digital x-ray unit

By Brian Casey

The vast majority of radiography systems currently on the market -- both digital and analog -- are based on a fairly conventional design that hasn't changed much in decades: an x-ray tube at one end and a film-screen cassette or detector at the other. But the new EOS system from French biotech firm Biospace Med represents a radical new design in digital radiography instrumentation that could carve out a niche when it becomes available in mid-2007.

Advanced visualization alone reduces coronary CTA accuracy

By Eric Barnes

Radiologists using advanced visualization software to get the best coronary CT angiography (CTA) results might want to take another look. Radiologists in Germany and the U.S. have concluded that reading CTA data using advanced visualization techniques alone can miss many relevant stenoses that would have been found with a glance at the native CT data.
