Nuclear Imaging in Patients with Differentiated Thyroid Cancer and Negative Radioactive Io-dine Scan
Background: Thyroid cancer is the most common endocrine malignancy in the world; however, these patients usually experience a high survival rate if they receive appropriate and timely treatment. Meanwhile, patients classified as having differentiated thyroid cancer with high thyroglobulin and negative iodine scan [Differentiated thyroid cancer with thyroglobulin elevation and negative iodine sc...
متن کاملDiagnostic management of suspected metastatic thyroid carcinoma: clinical value of octreotide scintigraphy in patients with negative high-dose radioiodine scans.
OBJECTIVES Somatostatin receptor scintigraphy (SRS) with (111)In-octreotide has been suggested as a potential tool for the detection of recurrent or metastatic differentiated thyroid cancer when no radioiodine uptake can be demonstrated in tumour sites. However, there is no consensus concerning the performance and clinical impact of this examination in such instances. DESIGN AND METHODS A pro...
متن کامل111In-pentetreotide scintigraphy and 18F FDG PET-CT in differentiated thyroid carcinoma metastases with negative whole body radioiodine scan.
Metastases of differentiated thyroid cancer (DTC) can lose affinity to radioiodine with the passage of time, with resultant difficulty in management. Thyroid tumors are known to express somatostatin receptors and therefore 111In-pentetreotide, somatostatin analogue, can visualize tumors with high concentration of somatostatin receptors. We report a case of I-131 whole body scan (WBS) negative r...
متن کاملDifferentiated Thyroid Carcinoma with Elevated Thyroglobulin and Negative Radioiodine Whole-Body Scan Metastases
Serum thyroglobulin (Tg) and Tg antibody (TgAb) levels, together with neck ultrasonography and 131I whole-body scintigraphy (WBS), are diagnostic tools for postoperative follow-up of patients with differentiated thyroid carcinoma (DTC). Generally, good correlation is seen between Tg and WBS in follow-up studies for DTC after thyroid remnant ablation. Undetectable serum Tg with negative WBS resu...
