This first example is a chart showing one facility’s average monthly Total DLP for its Chest Angio studies from early 2016 through Q1 2018.  Overall, this site reduced its average Total DLP for its Chest Angio studies by… Read More

TJC Dose Monitoring Requirements: XR-29 Dose Notifications Don’t Meet Them

When the facility I was working with was exploring using their scanners’ XR-29 Notifications to meet PI 02.01.01.A6 Dose Incident Identification requirements we reviewed the technical elements underpinning XR-29’s Dose Check feature.  After reading them we grew very concerned that XR-29’s dose notifications would not meet TJC’s requirement.  The facility submitted a question to TJC… Read More

CTDIvol vs DLP – a simple explanation

What do they represent? CTDIvol is based on measurements obtained when scanning either a 16cm or 32 cm phantom.   Essentially, it represents scanner output.  DLP is derived from CTDIvol, but incorporates a scan length component.  Both function as reasonable proxies for absorbed dose but do not represent the actual patient dose.  In other words, if… Read More

DoseID helps facilities identify duplicate and superfluous scanner protocols

One of the more interesting and unique benefits Dose Registry Support Services’ DoseID Program has for facilities is its ability to shed light on duplicate and superfluous protocols in use at their facilities.  The table to the right shows how one facility had 7 different protocols being used on a single scanner during a recent 3 month… Read More

Meeting The Joint Commission’s Dose Incident Identification Requirement Using the ACR’s Dose Index Registry

Here is the Abstract and link to an article I co-authored which was recently published in the JACR online edition, and which will be published in the JACR August print edition. The article describes how we used our ACR Dose Index Registry data to meet The Joint Commission’s requirement to establish expected dose ranges for every CT protocol and… Read More

Joint Commission Confirms Facilities Need an Expected Dose Range for All CT Protocols; Note to Self: XR-29 Does NOT Equal TJC Compliance

The following question was submitted to the Joint Commission: Must we establish an expected dose range for every imaging protocol or can we pick and choose the protocols for which we establish expected dose ranges and monitor only those? I interpret [PI.02.01.01.A.6.] to require monitoring of every protocol we use, not just some portion of… Read More
