A 68-year-old woman who underwent a thyroidectomy for bilateral goiter 20 years ago was referred to our department. The examination revealed a newly occurred thyroid nodule in the right central lobe. Unexpectedly the Tc-pertechnetate scan revealed several extrathyroidal foci right-sided supraclavicular, beside a cold thyroid nodule in the right lower lobe. Consecutive surgery and histology confirmed the suspected diagnosis of follicular thyroid cancer with multiple bone metastases. Whole-body scintigraphy performed after the following radioiodine therapy indicated disseminated osseous metastases.

A 3-year-old boy presented with intermittent abdominal pain, melena, and anemia since 2 months. Upper gastrointestinal endoscopy did not reveal any significant abnormality. The child was then referred...
Technetium-99m-pertechnetate whole-body SPET/CT scan in thyroidectomized differentiated thyroid cancer patients is a useful imaging modality in detecting remnant thyroid tissue, nodal and distant metastases before I therapy. A study of 416 patients.
In this study we aimed to evaluate the role of technetium-99m pertechnetate whole body scan (Tc WBS) with single photon emission tomography/computed tomography (SPET/CT) in detecting remnant thyroid t...
According to lung cancer guidelines, positron emission tomography scan is recommended for initial evaluation of bone metastasis. However, guidelines differ in their recommendations for when it should ...
Bone-seeking radiopharmaceuticals have the main role in the treatment of painful bone metastases. The aim of this study was to dosimetrically compare radiopharmaceuticals in use for bone pain palliati...
Heterotopic ossification is a rare phenomenon that refers to formation of bone outside the skeletal system. We present a 61-year-old woman who suffered from peritoneal cancer surgery 2 years ago, refe...
A non-fission sourced, solvent generator produced 99mTc intravenous injection, as 99mTc -MDP, is to be used as a bone scan diagnostic radiopharmaceutical for assessment of bone pathology u...
The purpose of this study is to evaluate technetium-99m (99mTc) pertechnetate produced by a cyclotron as a replacement for 99mTc pertechnetate obtained from a generator containing the pare...
The number of metastases in a patient with primary or recurrent prostate cancer has major prognostic implication. The purpose is to compare, in a pilot study, the diagnostic performance o...
A 99mTc Pertechnetate (G-PERT) scan is a nuclear medicine test that can create an image of the thyroid gland and other organs. G-PERT is approved by Health Canada for the direct imaging an...
This is a pilot study with the primary aim being to identify the minimum number of scans and measurements necessary to determine accurately the absorbed radiation doses delivered from inte...
Enlargement of the THYROID GLAND that may increase from about 20 grams to hundreds of grams in human adults. Goiter is observed in individuals with normal thyroid function (euthyroidism), thyroid deficiency (HYPOTHYROIDISM), or hormone overproduction (HYPERTHYROIDISM). Goiter may be congenital or acquired, sporadic or endemic (GOITER, ENDEMIC).
The use of combination of imaging techniques or platforms (e.g., MRI SCAN and PET SCAN) encompassing aspects of anatomical, functional, or molecular imaging methods.
An enlarged THYROID GLAND containing multiple nodules (THYROID NODULE), usually resulting from recurrent thyroid HYPERPLASIA and involution over many years to produce the irregular enlargement. Multinodular goiters may be nontoxic or may induce THYROTOXICOSIS.
An enlarged THYROID GLAND with at least 50% of the gland situated behind the STERNUM. It is an unusual presentation of an intrathoracic goiter. Substernal goiters frequently cause compression on the TRACHEA leading to deviation, narrowing, and respiratory symptoms.
A form of IODINE deficiency disorders characterized by an enlargement of the THYROID GLAND in a significantly large fraction of a POPULATION GROUP. Endemic goiter is common in mountainous and iodine-deficient areas of the world where the DIET contains insufficient amount of iodine.
Osteoporosis is a disease in which the bones become extremely porous, are subject to fracture, and heal slowly, occurring especially in women following menopause and often leading to curvature of the spine from vertebral collapse. Follow and track&n...
The thyroid is a butterfly-shaped gland in the neck, just above thecollarbone and is an endocrine gland that make hormones. These Thyroid hormones control the rate of many activities in the body, including how fast the body burns calories and how fast th...
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
