Prognostic utility of 90Y radioembolization dosimetry based on fusion 99mTc-macroaggregated albumin-99mTc-sulfur colloid SPECT.
UNLABELLED Planning hepatic (90)Y radioembolization activity requires balancing toxicity with efficacy. We developed a dual-tracer SPECT fusion imaging protocol that merges data on radioactivity distribution with physiologic liver mapping. METHODS Twenty-five patients with colorectal carcinoma and bilobar liver metastases received whole-liver radioembolization with resin microspheres prescrib...
متن کاملPersonalized predictive lung dosimetry by technetium-99m macroaggregated albumin SPECT/CT for yttrium-90 radioembolization
BACKGROUND For yttrium-90 ((90)Y) radioembolization, the common practice of assuming a standard 1,000-g lung mass for predictive dosimetry is fundamentally incongruent with the modern philosophy of personalized medicine. We recently developed a technique of personalized predictive lung dosimetry using technetium-99m ((99m)Tc) macroaggregated albumin (MAA) single photon emission computed tomogra...
متن کاملTranspulmonary passage of 99mTc macroaggregated albumin in healthy humans at rest and during maximal exercise.
We have demonstrated that 50-mum-diameter arteriovenous pathways exist in isolated, healthy human and baboon lungs, ventilated and perfused under physiological pressures. These findings have been confirmed and extended by demonstrating the passage of 25-microm microspheres through the lungs of exercising dogs, but not at rest. Determination of blood flow through these large-diameter intrapulmon...
متن کاملPreparation of human serum albumin microspheres (MSA) kit for lung imaging in Iran [Persian]
Radiolabeled Microspheres of human serum albumin (MSA) is of great importance in the analysis of regional lung perfusion. Preparation of MSA kit has been installed in our Division recently is carried out in two stages: 1. Production of albumin sphere particles with suitable sizes by using the spinning disk technique. 2. Formulation of MSA as a radiopharmacutical kit. So it can be labelled...
متن کاملLocal preparation, standardization and quality control of technetium labelled macroaggregated albumin for lung perfusion studies.
Lung perfusion study is an important investigation in various pulmonary diseases. The radiopharmaceutical commonly used now-a- days is imported macroaggregated human albumin (in kit form), which is labelled with technetium (Tc99m-MAA). Due to its high cost the technique could not be fully exploited. We have tried to locally prepare freeze dried MAA particles. Various parameters like concentrati...
