AIM To evaluate the usefulness of (11)C-methionine PET/CT (MET) in the localization of the parathyroid adenomas and to compare the results with those obtained with the conventional technique in double-phase (99m)Tc-sestamibi scintigraphy (MIBI). We evaluated the optimal timing to acquire MET images. MATERIAL AND METHODS A prospective study that included 14 patients (mean age: 65.5 ± 9.7 years...

ectopic paratliyroid adenoma might create a clinical dilemma in patients with hypercalcemia. radioisotopic scan is a sensitive and noninvasive method which can be useful in these patients. in this report a case of ectopic parathyroid adenoma is presented and the usefulness of tc-99m-mibi scintigraphy as compared with other modalities is discussed.

UNLABELLED The purpose of this prospective study was to evaluate the diagnostic value of early parathyroid SPECT combined with quantitative analysis as compared with planar imaging in patients undergoing minimally invasive radioguided surgery. METHODS A total of 52 consecutive patients with primary hyperparathyroidism underwent planar and SPECT parathyroid scintigraphy 2-5 d before surgery. E...

The aims of your case report is to show the predictivity of (99m)Tc-sestamibi (MIBI) scintigraphy and doppler ultrasound imaging on secondary hyperparathyroidism (SHPT) in a patient responsive to calcimimetic treatment. Moreover, it has been reported that calcimimetic has great potential in reducing the volume of the parathyroid gland. On the other hand, the MIBI scintigraphy is considered a cr...

Parathyroid scintigraphy with 99mTc-sestamibi (MIBI) is an established technique for localising abnormal parathyroid glands (PGs). However, the identification and localisation of PGs require much attention from medical experts are time-consuming. Artificial intelligence methods can offer assisting solution. This retrospective study enrolled 632 patients who underwent double-phase thyroid subtra...

OBJECTIVE Primary hyperparathyroidism (pHPT) is characterised by increased parathyroid hormone (PTH) secretion and consequently increased plasma calcium. During the last few decades parathyroid scintigraphy (PS), is applied in almost all patients with pPHT before surgery and specifically before minimally invasive parathyroidectomy. The aim of this study was to find the best cut-off levels of to...

UNLABELLED 99mTc-pertechnetate scintigraphy plays an essential role in the management of a variety of thyroid and parathyroid disorders. The authors report an unusual case of mediastinal tracer distribution of 99mTc-pertechnetate and 99mTc-MIBI in relation to an oesophageal conduit following oesophago-gastrectomy and reconstructive surgery on thyroid scintigraphy. This is a rare but important c...

OBJECTIVE In this study, our aim was to study the efficiency of gamma probe guided minimally invasive parathyroidectomy (GP-MIP), conducted without the intra-operative quick parathyroid hormone (QPTH) measurement in the cases of solitary parathyroid adenomas (SPA) detected with USG and dual phase 99mTc-MIBI parathyroid scintigraphy (PS) in the preoperative period. MATERIAL AND METHODS This cl...

A 10-yr-old boy visited Minoh City Hospital complaining of gross hematuria. Laboratory investigations revealed hypercalcemia, hypophosphatemia, and elevated serum levels of parathyroid hormone. A stone was found in the right ureter with drip infusion pyelography. A parathyroid adenoma was successfully diagnosed with computed tomography, ultrasonography, and methoxy-2-isobutyl isonitrile (MIBI) ...
