OBJECTIVE The aim of this study was to compare the efficacy of low- and high-dose (99m)Tc-MIBI protocols for intraoperative identification of hyperplastic parathyroid glands via gamma probe in secondary hyperparathyroidism. MATERIAL AND METHODS This retrospective study was conducted using a prospective database of 59 patients who had undergone radioguided subtotal parathyroidectomy between 20...

HYPOTHESIS Early, postinjection technetium Tc 99m sestamibi scintigraphy-single-photon emission computed tomography (MIBI-SPECT) can be used as the only localizing study for focused parathyroidectomy in patients with primary hyperparathyroidism. DESIGN During a 26-month period, 82 consecutive patients with primary hyperparathyroidism underwent a standard planar scan using a double-tracer subt...

Evaluation of thyroid uptake, by administration of small activities of radioactive iodine (I or I), is a well-defined procedure. Nowadays, nuclear medicine departments are using scintillation cameras coupled to pinhole collimators to perform such studies. On the other hand, gamma probes, which are normally used in radioguided surgical procedures, can technically be used for measuring the thyroi...

BACKGROUND The incidence, clinical importance, and optimal management of cervical and upper mediastinal lymph node metastasis from gastrointestinal and pancreatic neuroendocrine tumors (NETS) are largely unknown. Historically, cervical nodes have been regarded as asymptomatic and ignored. We hypothesized that these lesions have clinical implications and should be removed surgically. STUDY DES...

osteitis fibrosa cystica is the classic patognomonic form of skeletal disease in hyperparathyroidism that characterizes with decreased cortical bone thickness compared to increased cancellous bone. we present a case of 52-year old female patient with osteolysis of the left calf on radiographic images. the bone scan detected multiple focal pathological accumulations in the skull, left tibia, bot...
