The ​narnar app for contrast-enhanced ultrasound (CEUS) allows researchers to process and quantify perfusion studies of various organs (e.g., heart, kidney, liver, skeletal muscle), acquired across a range of research protocols, including cardiac realtime, cardiac triggered and generic realtime studies.

​Key features include:

• Automatic and manual image alignment
• Color-coding of digitally-subtracted images
• Averaged and maximum intensity projection (MIP) imaging
• Quantification and modeling of microvascular blood flow from time-videointensity curves, calculated in real-time.
• Parametric imaging of blood flow and velocity

Newer version more work

I liked the older version better where you can hit progressive after selecting a baseline and I got the values once I drew the regions of interest. Now I need to set heart rates and I can’t see the heart rate easily once imported into narnar.
