introduction: the purpose of the present study was to evaluate the effect of prednisolone on the sensitivity of bone scanning to detect the simulated closed fracture in the rat tibia.  methods: a total number of forty eight adult, male nmri rats randomly assigned into two parts, one part for 4 and other for 8 weeks experiments. each part has been divided into four groups, one group not receivi...

We present a case of a 15-year-old boy with osteoblastic osteosarcoma of the left distal femur. The patient was referred to bone scan for initial staging. On planar bone scan, there is increased uptake of 99mTc-MDP (99mTc-methylene diphosphonate) in the left distal femur. There are also multiple sites of abnormal tracer uptake projecting to the thoracic cage, initially assumed to be localized i...

Skeletal metastases are clinically significant because of associated symptoms, complications such as pathological fractures and their profound significance for staging treatment and prognosis. Detection of bone metastatic lesions allows radiation therapy or surgical interventions to prevent pathological fractures from disabling the patients. High sensitivity of bone scanning in determining the ...

OBJECTIVE At present, metastatic bone involvement is usually assessed using bone scintigraphy, which has a high sensitivity but a poor specificity. The objective of our study was to compare the sensibility of the 2-deoxy-2-[18F] fluoro-d-glucose positron emission tomography/computed tomography (F-18 FDG PET/CT) for the detection of bone metastasis in patients with non-small-cell lung cancer (NS...

Ubiquicidin 29-41 (UBI 29-41) is an antimicrobial peptide with six positively charged residues which preferentially binds to the negatively charged groups present on the microbial membrane by electrostatic interaction at the foci of infection. For this reason UBI 29-41 has been suggested to label by 99m Tc ( 99m Tc-UBI 2941)directly or by using coligand reagents like 6-hydrazinopyridine 3-carbo...
