(99m)Tc-galactosyl human serum albumin (GSA) scintigraphy is useful to evaluate hepatic function and hepatic functional reserve. A reliable SPECT and CT integrated system is now commercially available. Using this system, we can obtain (99m)Tc-GSA SPECT/CT fused imaging with a small registration error. Therefore, the (99m)Tc-GSA scintigraphy techniques prove more useful in clinical practice than...

Introduction: Nowadays, radioisotopes have a lot of therapeutic and diagnostic applications in nuclear medicine. The technetium-99m radioisotope is widely used in the diagnostic field. The technetium-99m radioisotope is widely used in the diagnostic field. In this study, in order to increase the absorption dose in thyroid cancer cells, the radioactive drug technetium-99m which ...

The impact of MR-guided attenuation correction (compared to CT-based AC) on the diagnosis anosmia based 99m-Tc Ethyl-Cysteinate-Dimer SPECT images

introduction: the endemic occurrence of new strains of tuberculosis around the globe has initiated new research on developing diagnostic radiopharmaceutical based on antibiotics. methods:tc-99m labeled streptomycin was prepared using freshly milked 99mtco4- and various concentrations of streptomycin, stannous chloride at various temperatures in high yield radiochemical purity shown by hplc/rtlc...

urinary tract infection (uti) is a common disease in childhood specially in female. in this study 50 patients with stablished diagnosis of uti were evaluated by both renal scan with tc-99m dmsa and renal sonography. the study revealed that most urinary tract infections are in children, female sex between 5-9 years of age. therefore the most important complications (renal scarring) are also comm...

Introduction:Diethylenetriaminepentaacetic acid (DTPA) is a chelating agent used as a radiopharmaceutical compound, 99mTc-DTPA, for renography. Doxorubicin (DOX) on the other hand is an effective chemotherapy drug used to treat a variety of solid malignancies.  Both 99mTc-DTPA and DOX may be used in close succession in patients undergoing DOX based chemoth...

  Introduction: Ubiquicidin (UBI) 29-41 is a synthetic antimicrobial peptide that binds with the microbial cell membrane at the location of infection. This study was conducted to evaluate its probable efficacy as an infection-imaging agent with potential to differentiate bacterial infection from sterile inflammation in humans. Methods: Fifteen diabetic foot patients ...

BACKGROUND Recent technical developments using solid-state technology have enabled rapid image acquisition with single photon emission computed tomography (SPECT) and have led to a renewed interest in technetium-99m-teboroxime (Tc-99m-teboroxime) as a myocardial imaging agent. Tc-99m-teboroxime has demonstrated high myocardial extraction, linear myocardial uptake relative to flow even at high f...

PURPOSE The aim of our study was to assess diagnostic accuracy of Tc-99m depreotide and Tc-99m-EDDA/HYNIC-TOC scintigraphy for evaluation of pulmonary lesions that appeared ambiguous on computed tomography (CT). MATERIAL AND METHODS Forty-nine consecutive patients (37 men and 12 women; mean age, 60 ± 11 years) with 60 pulmonary lesions on chest radiography and CT were referred for nuclear ima...
