PET/MRI PET MRI applications Having learned how to establish a PET/MRI facility (1), acquired an understanding of the science and technology (2), and gained insight into protocols and sequences in PET ...

Many variables can influence the results of gastric emptying scintigraphy (GES). A lack of standardization causes variability, limits comparisons, and decreases the credibility of the study. To ...

Calcific diskitis (CD) is a rare condition characterized by inflammation and calcification of an intervertebral disk, typically causing localized back pain. We present the case of a 65-y-old woman ...

18F-FDG PET/CT quantification of whole-body tumor burden in lymphoma is not routinely performed because of the lack of fast methods. Although the semiautomatic method is fast, it is not fast enough to ...

Pyelonephritis is an infection of the kidneys that is seen more commonly in children than the adults. 99mTc-dimercaptosuccinic acid (99mTc-DMSA) scanning is a radionuclide imaging study to detect ...

As nuclear medicine instructors shift toward online learning, it is imperative to use instructional strategies that align with the program’s theoretic foundation. Online learning does not require a ...

Meckel’s diverticulum is a vestigial remnant that arises from the failure of the omphalomesenteric duct to close. The omphalomesenteric duct connects the yolk sac in the embryo to the early foregut ...

The purpose of this paper is to introduce the principles of PET/CT imaging and describe the artifacts associated with it. PET/CT is a new imaging modality that integrates functional (PET) and ...

Data acquisition is substantially different in PET than it is in planar nuclear medicine and SPECT. There is an entirely different set of definitions and considerations. The objective of this paper is ...

Objective: Gamma cameras contain energy discriminators that allow only those photons within a specified energy range to be recorded. A spontaneous shift in peak of 1 head of a dual-head gamma camera ...

Alzheimer disease is associated with the accumulation of one or more misfolded proteins. The 2 primary proteins are amyloid-β and tau, which cause extracellular deposition of amyloid-β plaque and ...

In 1966, Griffith et al. used “a standard breakfast of ordinary food” labeled with chromium-51 to report the first use of gastric emptying scintigraphy (GES). As the procedure was refined over the ...
