Would Cardiac stress perfusion scan MRA highlight Pulmonary Hypertension if this was present?

Probably not. A cardiac echo/Doppler study would show pulmonary HTN changes by viewing the right ventricular function , size and pressure. There are additonsl studies that can also be done. It is very important to know WHY you have Pulmonary HTN. If due chronic Pulmonary embolism it is a serious situation for which there exists very effective Rx. Other causes can also be treated. Consult your doc.
