UNLABELLED The Society of Nuclear Medicine (SNM) published procedure guidelines for thyroid imaging in 1999. We wished to determine how many clinics performing thyroid imaging follow the guidelines and to what extent. Of particular interest to us was the choice of collimator. METHODS We developed a 10-question survey to obtain information on how hospitals perform thyroid imaging. The question...

A new non-invasive simple method for quantitative evaluation of thyroid was presented using graphical analysis of the transfer process of technetium-99m pertechnetate (99mTc) from the blood to thyroid. Thirty subjects were studied. After a bolus injection of 111 MBq of 99mTc, the data were recorded on a 128 x 128 matrix as 60 frames of 1.5-second duration. ROIs were placed over the aortic arch ...

OBJECTIVE The aim was quantitative assessment of parathyroid adenoma (PTA) uptake in dual tracer dynamic scintigraphy. METHODS In 78 patients, median age 58 (19-80) years, surgically treated for primary hyperparathyroidism (PHPT), with parathyroid hormone median 125 (70-658) pg/ml, we performed preoperative parathyroid scintigraphy, following EANM guidelines of subtraction and double-phase pr...

Abstract Purpose Molecular imaging with 99m Tc-methoxy-isobutyl-isonitrile ( Tc-MIBI, MIBI) has been used in the assessment of thyroid nodules (TNs) for more than two decades. Many studies showed that MIBI is a suitable tool to rule-out malignancy when negative. However, relatively low specificity and accuracy have described, thus, limiting its acceptance clinical practice. Additionally, differ...

Staging and risk stratification predicate the postoperative management of thyroid cancer patients, determining not only the need for (131)I therapy or alternative options (conservative management without ablation, surgical reintervention, or external-beam radiation therapy) but also the long-term follow-up strategy. This paper presents the progress made in the field of thyroid cancer imaging by...

BACKGROUND A change in a thyrometabolic state from severe hypothyroidism to thyrotoxicosis is very uncommon, but possible in some circumstances. CASE PRESENTATION A 27-year old female presented with clinical and biochemical thyrotoxicosis with a previous history chemo- and radiotherapy (including the neck region) for a Hodgkin's lymphoma (at the age of 18). At the age of 20 this was followed ...

We describe a 39-year-old woman presenting with a painless solitary thyroid nodule, initially without signs suggesting thyroiditis. The serum level of thyrotropin was suppressed whereas those of thyroxine and triiodothyronine were normal. Fine needle aspiration cytology showed no signs of inflammation or malignancy. One week later, the patient felt pain and tenderness on her neck, and erythrocy...

Accepted 23 April 1998 Summary We describe a 39-year-old woman presenting with a painless solitary thyroid nodule, initially without signs suggesting thyroiditis. The serum level ofthyrotropin was suppressed whereas those of thyroxine and triiodothyronine were normal. Fine needle aspiration cytology showed no signs ofinflammation or malignancy. One week later, the patient felt pain and tenderne...

We present a case of a parathyroid adenoma on the ipsilateral side of thyroid hemiagenesis-which, to our knowledge, is the third reported case of this entity. A 41-year-old man with nephrolithiasis was found to have elevated calcium and intact parathyroid hormone levels. Both ultrasound and technetium sestamibi scintigraphy with single photon emission computed tomography confirmed left thyroid ...
