Atlas of Artifacts in 201Tl SPECT Cardiac Perfusion Imaging
There are two predominant advantages of tomographic [single photon emission computed tomography (SPECT)] 201Tl technique over planar imaging. First, overlapping structures are separated and background activity is reduced resulting in improved contrast, and second, images can be generated in multiple planes of section, permitting precise localization of perfusion defects. However, the added complexity of SPECT poses a unique set of problems. With an understanding of the basic interpretation of thallium and sestamibi cardiac perfusion scintigraphy discussed by Watson and Smith in Chapter 1, an understanding of artifacts in tomographic (SPECT) 201Tl imaging is necessary. This chapter presents an extensive atlas demonstrating many of the more common artifacts experienced in interpretation of tomographic (SPECT) 201Tl imaging (see Table 2.1).
