Pulmonary Gas Embolism During Urological Laparoscopic Surgery: evaluation by 99mTc-MAA perfusion lung scintigraphy.

Ventilation/perfusion lung scintigraphy. Multiple applications besides pulmonary embolism.

Ventilation/perfusion scintigraphy is the diagnostic tool of choice for detection and monitoring of pulmonary embolism. However, the knowledge on its value for other or concurrent pathologies is poor. In this review scintigraphic characteristics of the main pathologies, interpretation and artefacts are described. Together with the understanding of pathophysiology of the lung, the potential gain...

Absent pulmonary uptake on 99mTc MAA perfusion lung scan due to severe right-to-left shunt.

c 5 XTRAPULMONARY accumulation of Tc macroaggregated albumin (MAA) is rarely een on perfusion lung scan, and has been reported n less than 4% of a study population of nearly 380 atients.1 It occurs when the agent bypasses the ungs due to a right-to-left (R-L) cardiac or pulonary shunt, when it is shunted to the portal vein efore reaching the right atrium and ventricle of he heart, and when the ...

The Utility of Hybrid SPECT/CT Lung Perfusion Scintigraphy in Pulmonary Embolism Diagnosis

Background: Pulmonary embolism (PE) is diagnosed either by ventilation/perfusion (V/Q) scintigraphy or pulmonary CT angiography. One of the imaging methods used in nuclear medicine is hybrid SPECT/CT scintigraphy. Objectives: The aim of this study was to evaluate the utility of SPECT/CT(Q) scintigraphy in the diagnosis of PE and to compare SPECT/ CT(Q) with planar(Q) and SPECT(Q) methods. Metho...
