Gastric emptying scintigraphy (GES) as now commonly performed measures only total gastric emptying. Intragastric meal distribution (IMD) immediately after meal ingestion (t = 0 min) (IMD) can assess ...

The accuracy and reproducibility of nuclear medicine gastric emptying scintigraphy (GES) require strict adherence to the Society of Nuclear Medicine and Molecular Imaging standardized protocol, which ...

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 ...

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 ...

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 ...

Neoadjuvant chemotherapy (NC) is a pivotal preoperative treatment for oral squamous cell carcinoma (OSCC), but its efficacy varies among patients. This study aims to predict the efficacy of NC in ...

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 ...

Technical factors play a critical role in the production of best-quality amyloid PET images for interpretation. This article provides specific instructions and general technical information about PET ...

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 ...

99mTc-labeled dimercaptosuccinic acid (99mTc-DMSA) imaging is a well-established and highly sensitive method for the diagnosis of several renal cortical disorders affecting children and adults.

The challenges of hybridizing PET and MRI as a simultaneous modality have been largely overcome in recent times. PET hybridized with MRI has seen the emergence of PET/MRI systems in the clinical ...
