RadLex extension enables better radiation dose tracking

Thursday, December 1 | 11:30 a.m.-11:40 a.m. | SSQ10-07 | Room S403A
In this talk, researchers will share how their proposed extension to the RadLex Playbook allows for comparisons of radiation dose on both an indication and series level.

The RadLex Playbook system for naming radiology procedures isn't currently well-suited to deal with exams that combine multiple indications, according to presenter Timothy Szczykutowicz, PhD, from the University of Wisconsin-Madison.

"For example, the RadLex Playbook allows one to map a biphasic liver and a routine chest, but it is not trivial to map the combination of the two of them," Szczykutowicz said. "Currently, this causes issues like the dose from the chest being attributed to the biphasic liver."

In another example, the combination of a routine head and C-spine CT would be mapped to one indication under the current RadLex Playbook strategy, leaving one of the two exams with an improper dose assignment, he said. Their institution has adopted an approach that uses the current RadLex Playbook system, but also adds a series identifier to each RadLex Playbook identifier (RPID).

"This allows each phase/series of a multipart exam to be mapped to the correct indication," he told AuntMinnie.com. "Our augmentation to the system also allows better dose and repeat rate tracking of exams since it is clear in our dose-monitoring database exactly what part of each protocol was scanned for a given exam."
