The purpose of this study was to compare estimation of radiation absorbed doses to patients following bone scans with technetium-99m-labeled methylene diphosphonate (MDP) with the estimates given in MIRDose software. In this study, each patient was injected 25 mCi of (99m)Tc-MDP. Whole-body images from thirty patients were acquired by gamma camera at 10, 60, 90, 180 minutes after (99m)Tc-MDP in...

BACKGROUND This study was designed to explore the feasibility of replacing the conventional peri-/intratumoural ultrasound (US)-guided technetium-99m albumin nanocolloid ((99m)Tc-nanocolloid) administration by an injection of the same tracer guided by a freehand single-photon emission computed tomography (SPECT) device in patients with non-palpable breast cancer with an iodine-125 ((125)I) seed...

The primary treatment of thyroid carcinoma is surgery and the outcome depends on its extent. The post-operative management alternatives in thyroid carcinoma include thyroid hormone, radio-iodine ablation (I-131 Na), external beam radiation therapy (EBRT) and occasionally adjuvant chemotherapy. This retrospective study analyzes the managements of 153 patients (102, 51), age range 10-96 yea...

This study has investigated the relationship between linear attenuation coefficients (mu) and Hounsfield units (HUs) for six materials covering the range of values found clinically. Narrow-beam mu values were measured by performing radionuclide transmission scans using (99m)Tc, (123)I, (131)I, (201)Tl and (111)In. The mu values were compared to published data. The relationships between mu and H...

(99m)Tc tricarbonyl glycine monomers, trimers, and pentamers were synthesized and evaluated for their radiolabeling and in vivo distribution characteristics. We synthesized a (99m)Tc-tricarbonyl precursor with a low oxidation state (I). (99m)Tc(CO)3(H2O)3 (+) was then made to react with monomeric and oligomeric glycine for the development of bifunctional chelating sequences for biomolecules. La...

1 of 2 DESCRIPTION A 55-year-old woman, resident in an iodine-suffi cient area, had a diffuse goitre for 25 years. She presented with a rapidly increasing swelling in the right frontal region for 3 months and increasing thyroid gland enlargement for 4 years. On examination, she had a diffuse, fi rm goitre (grade IV) with multiple tattoo marks and no cervical adenopathy. The swelling in the righ...

UNLABELLED Technical aspects and results of the dosimetric assessments of postoperative radioiodine ablation in the framework of an international, prospective, controlled, randomized, comparative study of the effectiveness of ablation therapy with 3.7 GBq (131)I in differentiated thyroid cancer after stimulation with recombinant human TSH (rhTSH) or by thyroid hormone withdrawal (THW) are prese...

Introduction: Appendicitis is one of the most common surgical emergencies. In spite of the relatively high rate of negative appendectomy, as a result of miss diagnosis, uncertainty of diagnosis still continues to challenge physicians. The objective of this prospective study was to investigate the role of 99mTc-Ubiquicidin (UBI) scintigraphy in the diagnosis of acute appendicitis and ...

BACKGROUND Diagnosis of protein loss into the gastrointestinal tract using noninvasive techniques is challenging. In people, scintigraphy not only is a sensitive tool to confirm protein-losing enteropathy (PLE), but it also allows for localization of protein loss. HYPOTHESIS/OBJECTIVES To investigate the feasibility of 99m Tc-labeled human serum albumin (HSA) scintigraphy in dogs with PLE in ...

BACKGROUND High-intensity focused ultrasound (HIFU) allows to inflict intracorporal thermal lesions without penetrating the skin or damaging the surrounding tissue. This analysis intends to assess the magnitude of HIFU-induced ablations within benign thyroid nodules using scintigraphic imaging with (99m)Tc. METHODS Ten cold, hot, or indifferent nodules were treated using multiple pulses of HI...
