Pulmonary Artery Dilatation-CT

Various authors have found that individuals with intrinsic lung disease can be identified as having pulmonary hypertension if the main pulmonary artery is greater than 29 mm. The upper limit of normal for the diameter of the pulmonary artery is 28.6 mm. A value greater than 28.6 mm suggests increased pressures in the pulmonary system.

Sir,
I am a student preparing for PGMEE.
We have read that:
Diameter of descending right pulmonary artery >16mm for males and >15mm for females denotes pulmonary hypertension.. (ques asked in AI2006 and AI2011)

Here this post says "The upper limit of normal for the diameter of the pulmonary artery is 28.6 mm."..

Is the word "MAIN" pulmonary artery reason for this 29mm as the reference value here??

Yes this is measurement for main pulmonary artery.
