Very low probability lung scan findings: A need for change
This study was conducted to determine the prevalence of PE in patients with V/Q scans interpreted as representing a very low probability (VLP) of PE (1-3 small segmental perfusion defects with a normal chest radiograph). An analysis of the entire data set obtained during the PIOPED study was performed. Of the total of 1,359 patients in whom the presence or absence of PE was confirmed, 80 ...
متن کاملReply 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 کاملRelationship of 99mtechnetium labelled macroaggregated albumin (99mTc-MAA) uptake by colorectal liver metastases to response following Selective Internal Radiation Therapy (SIRT)
BACKGROUND SIRT is an emerging treatment for liver tumours which relies on the selective uptake by tumour of 90Y microspheres following hepatic arterial injection. Response rates of around 90% are reported. Hepatic arterial injection of MAA gives an indication of the expected distribution of 90Y microspheres within the liver. This study sought to determine if the MAA scan could be predictive of...
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 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...
