The trifluoroacetyl group protects the nucleophilic HYNIC from unwanted side reactions yet allows radiolabelling with technetium-99m under mild conditions, due to efficient and specific promotion of deprotection by a technetium complex intermediate.

OBJECTIVES The purpose of this study was to evaluate interstitial alterations in myocardial remodeling using a radiolabeled Cy5.5-RGD imaging peptide (CRIP) that targets myofibroblasts. BACKGROUND Collagen deposition and interstitial fibrosis contribute to cardiac remodeling and heart failure after myocardial infarction (MI). Evaluation of myofibroblastic proliferation should provide indirect...

HYPOTHESIS Preoperative parathyroid and thyroid imaging using technetium Tc 99m sestamibi scintigraphy-single-photon emission computed tomography (Tc 99m MIBI SPECT) and technetium Tc 99m sodium pertechnetate, respectively, in patients with parathyroid adenomas and concomitant multinodular goiters enables the selection of those suitable for minimally invasive radio-guided surgery. DESIGN One ...

RATIONALE AND OBJECTIVES To evaluate the sensitivity of high-resolution breast-specific gamma imaging (BSGI) for the detection of ductal carcinoma in situ (DCIS) based on histopathology and to compare the sensitivity of BSGI with mammography and magnetic resonance imaging (MRI) for the detection of DCIS. MATERIALS AND METHODS Twenty women, mean 55 years (range 34-76 years), with 22 biopsy-pro...

background: hormesis is defined as the bio-positive response of something which is bio-negative in high doses. in the present study, the effect of radiation hormesis was evaluated on the survival rate of immunosuppressed balb/c mice by cyclosporine a. materials and methods: we used 75 consanguine, male, balb/c mice in this experiment. the first group received technetium-99m (3700bq) and the sec...

INTRODUCTION Although Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract and modern imaging techniques are available, its diagnosis remains problematic. CASE PRESENTATION A technetium-99 scan was performed in an 18-year-old man with abdominal pain, vomiting and rectal bleeding to confirm the presence of a Meckel's diverticulum which was not diagnosed...

In the application of UREX+1 process, technetium will be separated together with uranium and iodine within the first process step. After the separation of uranium, technetium and iodine must be immobilized by their incorporation in a suitable waste storage-form. Based on recent activities within the AFCI community, a potential candidate as waste storage form to immobilize technetium is to alloy...
