Diagnosis of Pulmonary Embolism by SPECT/CT Scintigraphy

Check if the same lab product or an alternative is used in the 5 most similar protocols

All patients with a clinical or laboratory suspicion of pulmonary embolism (PE) were evaluated by scintigraphy, i.e., the most common evaluation method for the diagnosis of PE.
Pulmonary perfusion assessment was performed after an intravenous injection of albumin macroaggregates labelled with radioactive technetium (^99mTc-MAA Makro-Albumon^®; Medi-Radiopharma Ltd., Érd, Hungary) intravenous. The imaging procedure was commenced immediately after the administration of the radiotracer and the images were acquired by a SPECT/CT hybrid dual-head gamma camera, Infinia VC Hawkeye 4 (GE Healthcare, General Electric Healthcare, Chicago, IL, USA). All SPECT/CT acquisitions were obtained with the patient in the same position. The SPECT/CT images were interpreted by Xeleris 1 and 2 Functional Imaging Workstations (GE Healthcare). The scintigrams were analyzed by two expert nuclear medicine specialists (with 7 and 28 years of experience, respectively).
Based on the SPECT/CT results, the following criteria for the diagnosis of PE were adopted: at least 1 segmental or two sub-segmental perfusion defects (wedge-shaped, base directed towards the pleura) without corresponding abnormalities in the pulmonary parenchyma.

Scintigraphic Criteria for Pulmonary Embolism

Check if the same lab product or an alternative is used in the 5 most similar protocols

All the images, both the planar and the SPECT/CT ones, were interpreted with the use of Xeleris 1 and 2 Functional Imaging Workstations (GE Healthcare). Scintigrams were analyzed by 2 nuclear medicine specialists (with 5 and >30 years of experience).
Based on the overall assessment of the SPECT/CT results, the following scintigraphic criteria for the diagnosis of PE were adopted: at least 1 segmental or 2 subsegmental perfusion defects (wedge shaped, base directed at the pleura) without abnormalities in the lung parenchyma (as visualized on CT) ( fig. 1 a,b). The following scintigraphic criteria were established for excluding PE: normal perfusion pattern ( fig. 2 ); perfusion defects that were not arranged in accordance with the pulmonary vasculature ( fig. 3 ), and perfusion defects caused by abnormalities in the lung parenchyma (as visualized on CT) ( fig. 1 c,d).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
