5 minutes! Join us! #AJRChat

Tonight we are joined by two authors of the article, Nadeen Abu Ata and Jonathan Dillman, as well as our #AJRChat moderators Christine Boone, MD, PhD and Cynthia Czawlytko, MD.

First time on an #AJRChat? Here's what you should know:

Q1. What aspect of the inflammatory process in Crohn disease do imaging-based blood flow measures most likely reflect? #AJRChat

Q2. What imaging factors are included in the MR index of activity (MaRIA) score? Did any of these consistently improve with treatment?

Christine Boone, MD, PhD AJR Nadeen Abu Ata Yes... changes over cardiac cycle, especially SMA... cardiac cycle flow is then extrapolate to ml per min... blood flow decreases quickly w treatment in most #crohns pts

Q3. Was there any relationship between normalized flow at the SMA and SMV pre and post treatment in patients with Crohn disease? #AJRChat

Cynthia Czawlytko, MD AJR Nadeen Abu Ata Consistent npo status is likely critical... oral contrast prep is not necessary as not evaluating bowel directly

Q4. What are potential benefits of this technique as a noninvasive quantitative marker of inflammation? What are potential disadvantages? #AJRChat

AJR Nadeen Abu Ata ???

AJR Thank you both for participating in #AJRChat and discussing your innovative approach to evaluating inflammation in Crohns Disease—and potentially an approach to evaluate other inflammatory diseases of the GI tract.

Thank you! Tan-Lucien Mohammed, MD, FACR
