Hi,  
Im a med student and pretty new about 3D Slicer.  
I want to calculate lung vessel BV5/TBV and PA:A.  
Recently i have been read this journal, [Radiographic Pulmonary Vessel Volume, Lung Function, and Airways Disease in the Framingham Heart Study - PMC](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7173739/) as a reference, but i still don’t know how to do it.

Can you help me explain step by step how to generate 3d model of lung vessel using CIP module, then calculate BV5/TBV and PA:A?

Many thanks.

Unfortunately, this can not be done out of the box with the current implementation of 3D Slicer CIP. @raul, cited in the above reference, most probably used specialized vessel segmentation software for his project in 2013.

You can, however, dig into the Lung CT Analyzer extension and create a vessel segmentation like this in 240 s on an appropriate hardware (no mouse clicks, with TotalSegmentator extended AI, using “lung\_vessel” subtask , [cite](https://www.sciencedirect.com/science/article/pii/S0720048X22001097) and [cite](https://academic.oup.com/bjs/article/108/Supplement_4/znab202.077/6287437)):

Hope that gets you started.
