Figure 1 Example of 18F-fluorodeoxyglucose-positron emission tomography and technetium-99m-sestamibi single-photon emission computed tomography images at baseline and during cardiac resynchronization therapy in a 50-year-old female patient with severe left ventricular dilation due to nonischemic cardiomyopathy. Shown are representative short-axis and horizontal long-axis slices of 1.2 cm thickness, as well as individual uptake values of the respective wall areas. A = anterior wall area; L = lateral wall area; P = posterior wall area; S = septal wall area.
