A series of 253 consecutive patients with proved primary hyperparathyroidism due to parathyroid tumours was reviewed. There were 68 (26.9%) men and 185 (73.1%) women, with a median age of 57 years (range 13-82 years). All patients, prior to successful parathyroidectomy, underwent one or more preoperative localization procedures such as: neck ultrasonography (US) in 191 (75.5%), (201)Tl/(99m)Tc-...

The paper presents results of studies on the possibility using ultrafiltration method supported by sorption low-cost, easily accessible aluminosilicates to purify water contaminated with radionuclides. An aqueous solution radionuclides in form cations at different oxidation states—Cs(I)-137, Co(II)-60 and Am(III)-241—as well as pertechnetate anions—TcO4?-99m—was treated proposed hybrid method. ...

UNLABELLED After the extravasation of a therapeutic dose of (131)I-metaiodobenzylguanidine that produced a radiation burn to a patient's forearm, we instituted a catheter placement verification protocol. METHODS Before therapy infusion, proper placement is verified by administering 37 MBq of (99m)Tc-pertechnetate through the catheter, and monitoring activity at the administration site and on ...

A Meckel's diverticulum was diagnosed by mesenteric angiography in a 34 year-old patient who presented with hematochezia and dropping hemoglobin. The case demonstrates the challenges often encountered in workup of occult gastrointestinal (GI) bleeding, and shows that angiographic diagnosis of Meckel's diverticulum is possible, even in the absence of angiographic evidence of active extravasation...

The goal of this work was to test whether an antibody-based agent approved for use as a single-photon-emitting imaging agent when radiolabeled with technetium-99m could be labeled comparably with a positron-emitting nuclide, technetium-94m. "Instant kits" containing lyophilized NP-4 antibody Fab' fragment of an anticarcinoembryonic antigen IgG (CEA-Scan) from the same manufactured lot were reco...

INTRODUCTION Radioactive iodine ((131)I) is widely prescribed for treatment of Graves' disease. A dose of 370 to 555 MBq (10 to 15 mCi) is usually enough, but reports of improved remission rates with single doses up to 20-30 mCi, and 38.5 mCi at most, exist. CASE PRESENTATION A 53-year-old male patient was evaluated in September 2005, with symptoms of thyrotoxicosis for 2 years. He presented ...

Molecular image-guided therapy has been demonstrated to be effective in improving diagnosis, prognosis, planning , and monitoring of personalized medication. Molecular imaging modalities include positron emission tomogra-phy (PET), single-photon emission-computed tomography (SPECT), magnetic resonance imaging (MRI), computed tomography (CT), ultrasound (US), and optical imaging (Ramen, quantum ...

OBJECTIVE Quantitative analysis of (99m)Tc-pertechnetate salivary gland scintigraphy has been used in the evaluation of salivary gland function, but so far no one method can be considered optimal for this task. In this study, a semiquantitative method providing 2 functional parameters for objective assessment of salivary gland function by scintillation camera imaging was tested. METHODS Twent...
