The recommended method, chest X-ray (CXR), lacks in accuracy, whereas quantitative tomographic lung scintigraphy [ventilation/perfusion single-photon emission computed tomography (V/P SPECT)] has shown promising results but needs independent validation.

Aims: Pulmonary congestion remains a diagnostic challenge in patients with heart failure (HF). The recommended method, chest X-ray (CXR), lacks in accuracy, whereas quantitative tomographic lung scintigraphy [ventilation/perfusion single-photon emission computed tomography (V/P SPECT)] has shown promising results but needs independent validation.

This test may be done during rest and while you exercise.

exercise thallium scintigraphy myocardial perfusion using thallium 201 as a tracer and 2007-01-11 Heart Views, Official publication of Gulf Heart Association.

Methods and results: We identified 13 969 patients who underwent adenosine or exercise stress SPECT myocardial perfusion scintigraphy (MPS). The percent myocardium ischaemic (%I) and fixed (%F) were calculated using 5 point/20-segment MPS scoring. Myocardial perfusion scintigraphy was performed as previously described using an elliptical 180 acquisition obtaining 60–64 projections over 180° for 35 (Tl-201) or 25 s (Tc-99m sestamibi) per projection. 8 Filtered backprojection without attenuation or scatter correction was used.

This test is called the “Myocardial scintigraphy perfusion imaging at exercice”, 21 Jun 2018 Perfusion imaging usually consists of stress and rest tests. Images are taken of your heart while at rest and after exercising or under stress.

Introduction Perfusion scintigraphy is a diagnostic imaging procedure that records the distribution of the pulmonary arterial blood ﬂ ow. Each, in principal conical, bronchopulmonary segment is supplied by a single artery.

Antigravitational perfusion distribution is typical for pulmonary congestion due to left heart failure. In supine patients, redistribution of perfusion towards anterior regions has been observed in 5–15% of patients with suspected PE [146, 150,151,152]. Myocardial perfusion scintigraphy: an important step between clinical assessment and coronary angiography in patients with stable chest pain The opinions expressed in this article are not necessarily those of the Editors of the European Heart Journal or of the European Society of Cardiology.
