Vertebral uptake of99mTc-macroaggregated albumin during lung perfusion scanning

Local 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...

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-...

Perfusion lung scanning in obliterative pulmonary hypertension.

Lung perfusion scanning in hepatic cirrhosis.

Abnormal lung perfusion scans using radioactive particles were found in five out of six cases of hepatic cirrhosis with arterial hypoxaemia. None had clinical evidence of cardiopulmonary disease or signs of pulmonary embolism on arteriography. The scan defects are probably caused by a disorder of the pulmonary microvasculature, which may show regional variation in severity.
