The recent introduction of high-resolution molecular imaging technology is considered by
many experts as a major breakthrough that will potentially lead to a revolutionary paradigm
shift in health care and revolutionize clinical practice. This paper intends to balance the
capabilities of the two major molecular imaging modalities used in nuclear medicine, namely
positron emission tomography (PET) and single photon emission computed tomography
(SPECT). The motivations are many-fold:(1) to gain a better understanding of the strengths …
