Study measures accuracy of iodine quantification

Tuesday, November 29 | 11:20 a.m.-11:30 a.m. | SSG12-06 | Room S403BThe accuracy of iodine quantification is becoming a critical question as researchers rely increasingly on dual-energy CT to quantify the composition of scanned materials. Researchers tested three different scanners to find out how well they do the job.

Canadians study changing approaches to suspected acute appendicitis

Sunday, November 27 | 12:05 p.m.-12:15 p.m. | SSA06-09 | Room N226As imaging for suspected appendicitis continues to evolve, researchers in Ontario, Canada, sent questionnaires to centers across the country to find out how they were handling these patients. Among the findings: Ultrasound is often the first choice for diagnosing younger patients.
