High resolution clinical and preclinical SPECT-CT

Dual modality preclinical and clinical SPECT/CT scanners have been under constant technological advance since the development of the first prototype dual modality clinical scanner in 1990. Dual modality SPECT/CT has rapidly become an established imaging tool in clinical and preclinical settings. In this article, we describe the present technology of dual modality SPECT/CT scanners used for clinical and preclinical imaging studies.
