Fortunately, the ventilation-perfusion lung scan is a reliable method of differentiating chronic thromboembolic pulmonary hypertension from PPH. One or more segmental or larger perfusion defects ...

Subsequently, all patients with suspected PVS undergo further imaging, including computed tomography scans and quantitative lung perfusion scans. As per an internally derived clinical protocol, ...

Introduction Single photon emission computed tomography ventilation/perfusion (SPECT V/Q ... and in patients with a high/likely clinical probability, lung imaging is required. CT pulmonary angiography ...

While a ventilation/perfusion lung scan had been performed in most local hospitals, surgical suitability was determined by both pulmonary CT angiography and conventional invasive pulmonary angiography ...

A ventilation/perfusion (V/Q) lung scan is performed early in the diagnostic pathway to differentiate those patients with CTEPH from those with other forms of pulmonary hypertension. In CTEPH, the V/Q ...

A diagnosis of PE required confirmation by a segmental or larger ventilation/perfusion mismatch on a nuclear lung scan or an intraluminal filling defect by pulmonary angiography. VTEs were classified ...

For example, if a patient with chronic graft-versus-host disease has lung disease, a ventilation–perfusion scan can be used to determine the areas of functional lung to avoid irradiating; however, ...

Her initial testing also included repeat imaging of her lung parenchyma with a high-resolution ... mediastinal and bilateral hilar lymph nodes. A ventilation-perfusion (VQ) scan was ordered to rule ...

The Chronic Thromboembolic Pulmonary Hypertension (CTEPH) program at Baylor St. Luke’s Medical Center is one of a handful of specialized programs in the country offering expert multidisciplinary care ...

Introduction: The pulmonary effects of e-cigarette use (or vaping) became a healthcare concern in 2019, following the rapid increase of e-cigarette-related or vaping-associated lung injury (EVALI) in ...

Figure 3. Formation of foamy macrophages and their role in TB pathogenesis. Foamy macrophages play a key role in the formation of caseous necrosis. They are formed when macrophages acquire cholesterol ...

In many cases the diagnosis can be made clinically, but the characteristic bone scan appearances of linear, superficial uptake on the posteromedial tibial cortex is useful in equivocal cases 18 (fig 2 ...
