There is suboptimal contrast opacification of the pulmonary arterial tree. The contrast density is not adequate for an acceptable quality CTPA. While no central filling defects are demonstrated, pulmonary embolism cannot be excluded on the basis of this study.
No secondary features of right heart strain such as reflux of contrast into the liver or straightening of the interventricular septum. The pulmonary artery is of normal calibre.
The lungs are clear.
