Incidental 131I Activity in the Deltoid Region on Posttherapy Radioiodine Scan.

A 71-year-old woman underwent a posttherapy radioiodine scan after I administration for papillary thyroid carcinoma. On day 1 of the posttreatment hospital isolation, the patient received a Pneumovax injection in the left deltoid muscle. A localized hypersensitivity reaction ensued with development of soft tissue edema and erythema at the Pneumovax injection site.

Multicenter validation of a shortened gastric-emptying protocol.

Unlabelled: Gastric emptying scintigraphy is considered to be the gold standard for detection of gastroparesis and other disorders of gastric motility; Society of Nuclear Medicine and Molecular Imaging guidelines are predicated on imaging over a period of 4 h, which is inconvenient for patients. Bonta et al. introduced 2-h criteria, which served to shorten the protocol in most patients, with negligible loss of accuracy.

Planar scintigraphic imaging of the gastrointestinal tract in clinical practice.

In the last 30 years, nuclear medicine has paralleled other imaging fields with the development of 3-dimensional techniques, including single-photon emission computed tomography and positron emission tomography. However, conventional nuclear medicine planar scintigraphy remains a common procedure at most imaging centers. Gastrointestinal studies constitute a significant portion of these planar procedures.
