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. All videos and images courtesy of Dr. Michalle Soudack and Dr. Aviv Hirschenbein.

Teaching parents about CT risks might pare unnecessary scans in kids
By Eric Barnes
Doctors rarely tell parents about the radiation risks associated with CT imaging of pediatric patients, and understandably so. Time is in short supply and the subject is complex. But a pilot study in Colorado found that parents can be easily educated about radiation risks with the aid of a short brochure -- and that they react quite well to what they learn. Knowing CT scans aren't risk-free might even reduce some of the demand for CT in situations where it might not be needed, according to the researchers.

Cardiology image and information system integration
Taking a page from the playbook of radiology departments, many cardiology practices today are seeking to move information beyond their group and into the information systems of the healthcare enterprise. Jeff Haglund, a consultant for Philips Medical Systems' healthcare information technology division, addresses the issues IT administrators may face in integrating radiology PACS with cardiology PACS, and making this a strong, workable solution.

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.

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.

High signal on T2 MR warns of poor healing after Achilles tendon repair
By Shalmali Pal
MRI can spot potential complications in Achilles tendon repair and is especially adept at pinpointing cysts or necrosis, according to researchers from Germany. In a study of 68 patients with partial or full-thickness tears of the Achilles tendon, they found that MRI was well-suited to monitor the healing and repair process, and that T2-weighted imaging could serve as an early indicator of outcome.
