Myocardial SPECT remains an important diagnostic technique in patients suspected of significant coronary artery disease. However, the diagnostic accuracy is hampered by several clinical and technical difficulties. Among these, soft tissue attenuation is one of the most frequent causes. Attenuation correction has the power to correct for these artifacts, increasing the diagnostic accuracy of myocardial SPECT. The current review summarizes the available clinical evidence for attenuation correction and raises the question if this technique is not underutilized in current clinical practice.
