we report here a rare case of lateral ectopia of thyroid without orthotopic thyroid tissue in an indian teenager, who was referred to our department for a thyroid scintigraphy. technetium pertechnetate (99mtco4- ) scan showed uptake in laterally placed soft tissue structure along with functioning thyroid tissue in high anterior midline neck region in line with thyroglossal tract. there is no up...

The authors present a case of subhyoid ectopic thyroid with mediolateral location diagnosed by technetium-99m pertechnetate scan. The ectopia was associated with hypothyroidism and developmental retardation.

Gastrointestinal duplication cysts are a rare congenital malformation in the gastrointestinal tract, most commonly seen ilium. The present study reported child with mid ileal cyst ofthe ectopic gastric mucosa that was diagnosed by Technetium-99m pertechnetate single-photon emission computed tomography-computed tomography (SPECT-CT) scintigraphy. can massive lower bleeding early childhood (Mecke...

This study retrospectively reviews 60 cases of primary hyperparathyroidism, 21 of whom underwent technetium 99 sestamibi scanning and 10 of whom underwent thallium 201/technetium 99 pertechnetate scanning preoperatively. The sestamibi and thallium scans demonstrated an 89.5% and a 62.5% sensitivity rate for adenoma, respectively. Neither scan demonstrated hyperplastic glands well. Although the ...

Technetium-99m pertechnetate scintigraphy in three patients with pathologically proven peripheral nerve tumors (six in total) demonstrated its ability to assess accurately the size, location, and the extent of all lesions. Pertechnetate localized only in areas of abnormal nerve involvement and all lesions were better seen in delayed images than the earlier ones. Pertechnetate imaging appears to...

The aim of this study is to determine the contribution of neck and chest Tc-pertechnetate scan to the management of postoperative patients with suspicious metastatic differentiated thyroid cancer (DTC), particularly to the prediction of response to radioiodine (I) therapy. Just before I administration, a total of 184 postoperative DTC patients with stimulated serum thyroglobulin (ssTg) >10 ng/m...

The goal of this work was to test whether an antibody-based agent approved for use as a single-photon-emitting imaging agent when radiolabeled with technetium-99m could be labeled comparably with a positron-emitting nuclide, technetium-94m. "Instant kits" containing lyophilized NP-4 antibody Fab' fragment of an anticarcinoembryonic antigen IgG (CEA-Scan) from the same manufactured lot were reco...
