What is First Pass Imaging?

First pass imaging is a specialized exam to determine right ventricle function or Pulmonary Hypertension.

Indication

Expectations

The electrodes used must be placed securely on the skin to ensure an optimal ECG signal.  You will be in the department for 45-60 minutes.  Nuclear Medicine staff technologists will withdraw 3 cc of blood by starting a hep-loc to tag with an isotope.  It will take 15-20 minutes for your blood to tag with the isotope.  At that point your blood will be reinjected and 3 patches for an EKG will be applied to your chest.  Images of the Anterior, LAO and Left Lateral views of the heart will be taken.
