Abstract

This is a case of a 47-year-old male, diagnosed with situs inversus with dextrocardia, who had episodes of chest heaviness. He was referred for a myocardial perfusion imaging using the rest and stress protocol. SPECT short axis, vertical and horizontal long axis projections were acquired after injection of Tc99m Tetrofosmin. One hundred eighty degree imaging was performed on a dual-head camera from the left anterior oblique to right posterior oblique, instead of the usual right anterior oblique to left posterior oblique. Results showed mild stress-induced myocardial ischemia in the apex. Non-invasive cardiac imaging acquisition in this case requires protocol adjustment to correctly acquire and process the data.
