The aim of study is to determine if 99mTc Annexin V-128 (AxV- 128/Tc) single photon emission
computed tomography (SPECT)-computed tomography (CT) can detect perioperative lung injury.
The investigators will study patients undergoing major surgery, specifically Whipple
procedures (pancreatico-duodenectomies) and compare AxV-128/Tc SPECT-CT scans before and
after surgery in Chronic Obstructive Pulmonary Disease (COPD) and non-COPD patients.
