Procedure Guideline for Adult Solid-Meal Gastric-Emptying Study 3.0
The purpose of this guideline is to assist nuclear medicine practitioners in recommending, performing, interpreting, and reporting the results of gastric-emptying and motility studies in adults. Radionuclide studies of gastric emptying and motility are the most comprehensive and physiologic studies of gastric motor function available. The studies are noninvasive, use a physiologic meal (solids ...
Procedure Guideline for Myocardial Perfusion Imaging 3.3
The purpose of this guideline is to assist nuclear medicine practitioners in recommending, performing, interpreting, and reporting the results of myocardial perfusion imaging studies. II. BACKGROUND INFORMATION AND DEFINITIONS. Myocardial perfusion imaging uses an intravenously administered radiopharmaceutical to depict the distribution of ...
Consensus Recommendations for Gastric Emptying ...
This consensus statement from the members of the American Neurogastroenterology and Motility Society and the Society of Nuclear Medicine recommends a standardized method for measuring gastric emptying (GE) by scintigraphy. A low-fat, egg-white meal with imaging at 0, 1, 2, and 4 h after meal ingestion, as described by a published multicenter protocol, provides standardized information about ...
SNM Practice Guideline for Hepatobiliary Scintigraphy 4.0
Dec 1, 2010 · III. DEFINITIONS. Hepatobiliary scintigraphy is a radionuclide diagnostic imaging study (including planar imaging, SPECT, or hybrid imaging such as SPECT/CT) that evaluates hepatocellular function and the biliary system by tracing the production and flow of bile from the formative phase in the liver, and its passage through the biliary system into the small intestine.
Gastric Emptying Scintigraphy - Journal of Nuclear Medicine …
Jun 1, 2019 · Gastric emptying is a complex physiologic process controlled by the physical and chemical composition of the GES meal, sympathetic and parasympathetic innervation of the stomach, and circulating neuroendocrine transmitters. The type of food, volume, and caloric content significantly affect the rate of gastric emptying.
Artifacts and Pitfalls in Myocardial Perfusion Imaging
Myocardial perfusion imaging (MPI) is an important imaging modality in the management of patients with cardiovascular disease. MPI plays a key role in diagnosing cardiovascular disease, establishing prognosis, assessing the effectiveness of therapy, and evaluating viability. However, MPI is a complex process, subject to a variety of artifacts and pitfalls, which may limit its …
Principles of CT: Radiation Dose and Image Quality
This article discusses CT radiation dose, the measurement of CT dose, and CT image quality. The most commonly used dose descriptor is CT dose index, which represents the dose to a location (e.g., depth) in a scanned volume from a complete series of slices. A weighted average of the CT dose index measured at the center and periphery of dose phantoms provides a convenient single-number estimate ...
