introduction: the radioimmunoscintigraphy (ris) has found widespread clinical applications in  tumor  diagnosis.  human  epithelial  mucin,  muc1,  is  commonly  over  expressed  in  adenocarcinoma including 80% of breast cancers and represents a useful target for ris. the pr81  is  a  new  murine  anti-muc1  monoclonal  antibody  that  was  found  to  react  with  the  membrane  extracts of se...

Facticious accumulation of the radiopharmaceutical in the urinary draining system as shown by routine renal tests, like technetium- 99m-diethylenetriamine pentacetic acid, technetium-99m-mercaptylacetyltriglycine or technetium-99m-glucoheptonate renograms can be re-evaluated by administering a diuretic, like furosemide (FS) and obtaining post FS dynamic and static images. Urinary tract obstruct...

Askin tumor is a rare disease which had previously been reported as being thallium-201 and gallium-67 avid. Varying data regarding 18F- fluorodeoxyglucose metabolism has been described with Ewing family of soft tissue tumors. In this case, we present a patient found to have an Askin tumor of the left chest wall which demonstrated indium-111 pentetreotide and technetium-99m MIBI avidity. The les...

Introduction: In Islamic countries in the month of Holy Ramadan many Muslims based on their religious Legislation refuse fluid intake during the fasting time though instructed to drink after injection of Tc-99m Methylene-diphosphonates [Tc-99m MDP] used for skeletal scintigraphy. We aimed to establish whether fluid restriction in Tc-99m MDP skeletal scintigraphy has an impact on its quality. M...

A nine-month old male child presented with low-grade fever, loose stools and facial puffiness. Clinically patient was otherwise normal except for a firm liver on palpation. The laboratory tests revealed hypoproteinemia (both albumin and globulin) and iron deficiency anemia. Differential diagnosis considered were: 1. Nephrotic syndrome, 2. Cystic fibrosis (in view of recurrent diarrhea and respi...

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.

Accurate and timely diagnosis of prosthetic joint infection is essential to initiate early treatment and achieve a favorable outcome. In this study, we used a rabbit model to assess the feasibility of technetium-99m-labeled annexin V for detecting prosthetic joint infection. Right knee arthroplasty was performed on 24 New Zealand rabbits. After surgery, methicillin-susceptible Staphylococcus au...

PURPOSE We compared signal change on magnetic resonance imaging (MRI) with fat suppression and bone scan activity of lumbar facet joints to determine if these two imaging findings are correlated. METHODS We retrospectively identified all patients who underwent imaging of the lumbar spine for pain evaluation using both technetium-99m methylene disphosphonate single-photon emission computed tom...

Background Camurati-Engelmann disease (CED) is a rare osteosclerotic autosomal dominant condition responsible for chronic diaphyseal pain. It caused by mutations of Tumor Growth Factor β1 (TGFβ1 ) gene. Currently there are no validated therapies this condition. Objectives To test the efficacy anti-TNFα antibody in patient affected CED. Methods Etanercept 50 mg per week was administered with Dat...
