Reply to 'Accurate measurement of the normality values of macroaggregated albumin lung perfusion scan in hepatopulmonary syndrome'.
Dear Editor, It is with great interest that we reply to the letter of questions and comments of Dr. Prof. Xiao Li to the article ‘‘Evaluation of normality and reproducibility parameters of Tc-MAA scintigraphy in the diagnosis of intrapulmonary vascular dilatations’’. However, we do not agree with the criticism regarding the group evaluated and the protocol used for scintigraphy with technetium-...
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 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...
متن کاملHepatopulmonary syndrome: a prospective study of relationships between severity of liver disease, PaO(2) response to 100% oxygen, and brain uptake after (99m)Tc MAA lung scanning.
BACKGROUND Because of the spectrum of intrapulmonary vascular dilation that characterizes hepatopulmonary syndrome (HPS), PaO(2) while breathing 100% oxygen varies. Abnormal extrapulmonary uptake of (99m)Tc macroaggregated albumin (MAA) after lung perfusion is common. GOAL To describe relationships between (1) severity of liver disease measured by the Child-Pugh (CP) classification; (2) PaO(2...
متن کاملUnexpected stomach uptake of technetium-99m-MDP.
Two pediatric cases are described in which the results of each patient's bone scan demonstrated abnormal stomach uptake. There have been a number of reports in the literature describing stomach uptake of bone agents, however, it is an uncommon finding.
