History:	SOB, hypoxia, low O2 sats, respiratory distress, etc.
Surview:	Apices to mid-renal
IV Contrast:	85 mL / Omnipaque 350
IV Contrast:	Test bolus injection 20mL @ 5mL/sec - followed by 50mL saline @ 5mL/sec - adding 5 seconds to the time of the test bolus

Note: Larger patients – increase amount of IV contrast & increase flow rate to 6cc/sec

**For morbidly obese pts. Calculate contrast amount by 1.2cc per kilogram. Max. 150cc
Use 100 kVp if BMI is <30
Use 120 kVp if BMI is >30
FOR ALL PE STUDIES - INCLUDE THE APICES IN THE SCAN
DoseRight (ACS), Z-DOM and Adaptive filter should be on

BREATHING INSTRUCTIONS:

Practicing and coaching the breath hold is also extremely important and should be performed on inspiration.

Tracker Scan:	Start at the level of the carina
ROI :	Place the ROI in the main pulmonary artery
HU :	120
Sacn:	Scan superior to inferior

Tip :

For large pts. you will get a better study if you place the tracker ROI out in the lung field and visually watch the contrast fill the Pulmonary Arteries and manually start the scan.
