Figure 1 Selection of two short-axis tomograms and one horizontal long-axis tomogram for RV assessment and schematic presentation of six RV segments (Seg). Segments 1, 2, 3 and 4 are derived from the basal and apical one-third slices, in which the whole LV circumference is visualized. The RV horizontal long axis (segments 5 and 6) is selected at the mid-ventricular transverse level by reference to LV slices. Right ventricular uptake was visually scored as follows: 3+ = no definite abnormality; 2+ = slight reduced uptake; 1+ = markedly reduced uptake; 0 = defect.
