[ 1 ] - Administration of 99mTc-DTPA in combination with doxorubicin alters the radiopharmaceutical biodistribution in rats
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...
[ 2 ] - Measurements of output factors using different ionization chambers and build up caps
Background: The aim of this work was to study the output factors for Linac using different ionization chambers and build up caps. Materials and Methods: Output factors were measured for open square fields (3 × 3 cm to 40 × 40 cm) defined by collimator jaws for 6 and 15 MV photon beams from a Varian Clinac 2100C accelerator were measured. The measurements in air were performed using Com...
[ 3 ] - Evaluation of radiochemical purities of routinely used radiopharmaceuticals: Three years’ experience of a single institute
Introduction: Radiochemical purity (RCP) is a routine quality control test carried out at nuclear medicine to determine the concentration of various chemical species present in the radiopharmaceuticals (RPs). The present work describes three years of experience in a single institute for the measurement of these impurities in the RPs preparations. Methods: </strong...
[ 4 ] - Factors affecting discharge time of well differentiated thyroid cancer patients receiving 131I therapy: Five years’ experience
Introduction:The post-surgical management of patients with differentiated thyroid cancer include ablation of remnant local and distant metastatic tissues with 131I therapy, which accentuates isolation of the patient in order to avoid unnecessary radiation exposure to the care givers, general public and the environment. The duration of isolation is subject to the redu...
