Thirteen healthy teenage girls with idiopathic adolescent scoliosis were studied using multiple thermoluminescent dosimeters while undergoing standard diagnostic roentgenograms. Average organ doses for each anteroposterior and lateral examination were calculated for bone marrow, gastrointestinal tract, lungs, breast tissue, and gonads. Given an average of(More)
Measurements were made to determine if there was an optimal kVp that would maximize radiographic contrast for various materials while minimizing average patient dose. Radiographs were made of a 17-cm-thick plexiglass phantom (to simulate a typical abdomen) with added regions of plexiglass, hydroxyapatite, and iodine with peak kilovoltages from 40 to 150 kVp(More)
Microspheres conjugated to radioisotopes and chemotherapeutic agents are playing an important investigative and clinical role in the management of metastatic neoplasms. The purpose of our investigation was to histologically assess the basis for regional intra-arterial microsphere therapy, by comparing the spatial distribution of microspheres in the tumor(More)
RATIONALE AND OBJECTIVES The authors investigated the effect of multimerization on the relaxivity of macrocyclic gadolinium (Gd) chelates. The objective was to develop more sensitive magnetic resonance imaging (MRI) contrast agents to study biochemical processes. METHODS Covalently linked nonionic, macrocyclic, multimeric lanthanide chelates that belong(More)
