Encouraged by the response to its November 1 release of the RadLex Playbook, the RSNA is pumping up more interest in the playbook with image sharing demonstrations at the RSNA 2011 meeting in Chicago.
The playbook features a standard, uniformly structured set of names for radiological procedures. The initial release covers more than 350 common CT procedures.
The lexicon was developed by extracting names from lists of orderable procedures from several large imaging sites and adapting them to a standardized structure defined for the playbook, according to the organization.
The list is designed to address the current babble of terms used interchangeably to refer to common procedures. It enables more accurate ordering and scheduling, standardized image acquisition protocols, automated selection of reporting templates and more efficient and accurate coding and billing.
The RSNA plans to expand the playbook in 2012 with standardized terms for MRI and x-ray procedures.
![Axial images from unenhanced calcium score cardiac CT (left) and curved planar reformation images from CT angiography (right) show that higher long-term exposure to air pollution is associated with greater coronary artery calcium and more obstructive coronary artery disease (CAD). Top row: Images in a 68-year-old male patient with higher 10-year mean ambient air pollution exposure (7.9 μg/m3 for particulate matter measuring ≤2.5 μm in diameter [PM2.5] and 17.4 parts per billion [ppb] for NO2) with extensive CAD (coronary artery calcium score [CACS] >1,000 and obstructive CAD [≥70% diameter stenosis]). Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/06/hanneman.r6SMLzkezo.png?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
