Beyond Crohn Disease
Inflammatory bowel disease (IBD) has a rising prevalence in children and an increasing number of adults living with IBD were diagnosed in childhood. This chronic disorder requires frequent cross-sectional imaging…
Repaired Congenital Heart Disease in Older Children and Adults
Because of a recent increase in survival rates and life expectancy of patients with congenital heart disease (CHD), radiologists are facing new challenges when imaging the peculiar anatomy of individuals…
Brain Malformations at All Ages
Congenital brain malformations comprise a spectrum of disorders that result from a variety of causes, including genetic abnormalities, ischemia, infections, and toxic exposures. Although most cases are discovered in infancy…
Cardiovascular System
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…
Central Nervous System
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…
Oncology: F-18 Fluorodeoxyglucose Positron Emission Tomography
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…
Inflammation and Infection
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…
Oncology—Beyond Fluorodeoxyglucose
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…
Hepatic, Biliary, and Splenic Scintigraphy
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…
The Skeletal System
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…
