The left PA is dilated, while the right PA is normal in calibre. There is no mosaic perfusion- which is contesting against airway cause or pulmonary arterial hypertension as the cause of the dilatation of the pulmonary artery. The ratio of the segmental PA and adjacent bronchi is <1, which is also contesting against precapillary pulmonary hypertension.
(images not shown here) The RV is showing wall thickening (thickness of the free wall of the TV is > 4mm). However, there is no leftward bowing of the IV septum. There is evidence of only very minimal regurgitation of the contrast into the IVC (images not included). The pulmonary veins are normal in calibre, which is contesting against pulmonary venous hypertension.
