A number of noninvasive cardiac diagnostic imaging studies are available to the cardiologist, which include echocardiography, computed tomography (CT), CT angiography, and magnetic resonance imaging. The continuing value of cardiac…

Molecular imaging examinations using positron emission tomography (PET) and single-photon emission computed tomography (SPECT) are frequently used in the brain because they can complement the anatomical information from magnetic resonance…

Background For decades, positron emission tomography (PET) imaging was largely limited to use in research. The development of dedicated PET cameras, the widespread expansion of cyclotron production facilities, and the…

Infection imaging has long been an important indication for scintigraphy. Gallium-67 citrate (Ga-67) was the first infection-seeking radiopharmaceutical used clinically. It is still in use today, however, in a much…

This chapter reviews tumor scintigraphy using radiopharmaceuticals other than F-18 fluorodeoxyglucose (FDG), as well as therapeutic radiopharmaceuticals for specific malignancies ( Box 13.1 ). Theranostics is a topic of increasing…

Liver, biliary, and splenic scintigraphy have played an important diagnostic imaging role in patient management since the 1960s. Today’s radiopharmaceuticals have mechanisms of uptake and localization that take advantage of…

Made up of inorganic calcium hydroxyapatite (Ca 10 [PO 4 ] 6 [OH] 2) crystal and an organic matrix of collagen and blood vessels, the skeleton is constantly changing and…

The use of a radionuclide to measure gastric transit was first described in 1966. Radionuclide gastric emptying scintigraphy has long been the standard methodology for measuring gastric transit. In this…
