Thyroid Uptake and ScanDavid EarlGraefAllergy
An imaging test typically shows the uptake of radioactive iodine by normal thyroid tissue. Areas or nodules that are producing excess hormone (referred to as hyperfunctioning) will show increased uptake of iodine. These are referred to as "hot" nodules or areas. By contrast, so-called "cold"...
Related tests include ACTH, angiography adrenal, biopsy thyroid, calcium, CT renal, cortisol, glucose, radioactive iodine uptake, sodium, thyroglobulin, thyroid antibodies, TBII, thyroid scan, TSH, TT3, T4, FT4, and US thyroid. Refer to the Endocrine System table at the end of the book for...
131I-uptake at twenty four hour was 4 to 42 percent (the mean value is 24.5%) in type II. Therefore, mottled type with 131I-scan could not be due to the low thyroidal uptake of 131I-iodine.C) About the thyroid function at the time of scanning, 30 patients were euthyroid, 4 ...
Study report: The 123I post-thyroidectomy scan (a, whole-body anterior and posterior views, b, pinhole images of the neck) revealed several foci of remnant thyroid tissue in the neck as well as a focal area of tracer uptake in a left lung nodule as demonstrated on SPECT/CT (c), ...

A RAIU scan showed diffuse thyroid gland uptake without any evidence of a focal hyper- or hypofunctioning nodule and a thyroid ultrasound revealed heterogeneous echogenicity and a 1.9 x 0.8 x 1.3 cm hypoechoic solid nodule within the isthmus. On her initial evaluation, physical examination was ...
Second, although hypo- and euthyroid animals contained detectable BAT, hyperthyroid mice displayed an increased metabolic activity as determined by 18F-FDG uptake (Fig. 6C+D). In line with this observation, fatty acid oxidation activity in BAT was increased in hyperthyroid mice as determined by...
The time-activity curve of a 1-minute scan was employed to derive EBF parameters; likewise, the time-activity curve of a 20-minute scan was used to determine maximum instant uptake, and the gradient of the curve from the 10th to 20th minute was used to assess maximum uptake. Results: ...
Abstract Considerable developments in nuclear medicine imaging technology have occurred in the past decade, with SPECT/CT obtained on hybrid gamma cameras with in-line CT proving to be a powerful diagnostic tool that allows for accurate anatomic localization and characterization of radioactivity distributio...
