A novel tagging method is introduced that increases the spatial resolution of estimates of myocardial radial thickening. The separation of adjacent parallel tag planes is customized to match the expected motion of specific regions of the heart wall. In regions in which the tags increase their separation over systole (radial thickening), the tag planes are placed close together at end diastole. In regions in which the tags decrease their separation over systole (circumferential shortening), the tags are placed farther apart so they remain detectable at end systole. With variable separation tagging (VTAG), parallel plane tagging can be used to obtain higher-resolution estimates of radial thickening and circumferential shortening simultaneously.

This is the first article of a four-part series on nuclear cardiology. This article introduces and reviews the anatomy and function of the normal heart. Future articles will develop the contribution of nuclear medicine techniques in evaluating myocardial perfusion, function and viability. This article describes the external and internal features of the heart and its vascularization, conducting system and physiological function. After reading this article, the reader should understand the anatomy and the function of the normal heart.
