Figure 2 Row tomographic display of stress-only Tc-99m sestamibi SPECT in a male with short axis (SA) slices (top), vertical long axis (VLA) slices (middle) and horizontal long axis (HLA) slices (bottom). The top row of each pair is without attenuation correction (non-AC) and the bottom with AC (AC). The arrows on the reconstructed slices point to an inferior wall perfusion defect on the non-AC images, and the arrow on the projection images point to the diaphragm.
