Ventilation-perfusion scintigraphy is a functional imaging biomarker that has the potential of captivating the heterogeneity of chronic obstructive pulmonary disease (COPD). It specifically images the distribution of ventilation and perfusion within the lungs, which is a critical pathophysiological component of COPD. The extent of ventilation defects and ventilation inhomogeneity, as well as the ventilation-perfusion ratio distribution thus correlate with severity of disease. Furthermore… 
Multimodality Imaging of Pulmonary Hypertension
Various findings of pulmonary hypertension on computed tomography (CT) and ventilation/perfusion (V/Q) scans that can help one to differentiate between the various etiologies are reviewed.

Comparison of 81mKrypton and 99mTc-Technegas for ventilation single-photon emission computed tomography in severe chronic obstructive pulmonary disease
Caution should be taken when replacing 81mKrypton with 99mTc-Technegas as a ventilation tracer in patients with severe COPD as there are significant differences in the distribution of the tracers over the lungs.
A retrospective evaluation of the pulmonary function tests and quality of life assessment surveys of emphysema patients subject to coil treatment.
A statistically significant improvement was observed in the PFT parameters and quality of life questionnaires following the coil procedure which is a bronchoscopic volume reduction procedure.
Dynamic Chest X-Ray Using a Flat-Panel Detector System: Technique and Applications
DXR may serve as an alternative to pulmonary function tests in patients requiring contact inhibition, including patients with suspected or confirmed coronavirus disease 2019 or other infectious diseases and has a great potential to play an important role in the clinical setting.
Quantitative analysis of changes in lung density by dynamic chest radiography in association with CT values: a virtual imaging study and initial clinical corroboration
No significant differences were detected for each condition of thoracic breathing, suggesting that the same regression line inclination values measured across the entire lung can be used for the conversion of Δpixel values, providing a quantitative analysis that can be correlated with ΔCT values.
Molecular Imaging of Inflammatory Disease
In vivo imaging of inflammation ultimately facilitates an improved accuracy of diagnostics and monitoring of patients to allow for better patient care, and highly specific molecular imaging of inflammatory biomarkers allows for earlier diagnosis to prevent irreversible damage.
Signs of tracheobronchitis may constitute the principal finding on the lung SPECT/CT images of COVID-19 patients
Signs of tracheobronchitis may constitute the principal finding on lung SPECT/CT images of COVID-19 patients with shortness of breath.
Synthetic pulmonary perfusion images from 4DCT for functional avoidance using deep learning
It is demonstrated that from 4DCT alone, a deep learning model can generate synthetic perfusion images with potential application in functional avoidance treatment planning.
A Brief History of Lung Ventilation and Perfusion Imaging Over the 50-Year Tenure of the Editors of Seminars in Nuclear Medicine.
The history of the lung scan, its highs and lows, the transition from planar to SPECT/CT V/Q scans, and the future that is in store in this age of multimodality functional imaging are reviewed.


Applications of Ventilation-Perfusion Scintigraphy in Surgical Management of Chronic Obstructive Lung Disease and Cancer.
Ventilation-perfusion scintigraphy (VPS) depicts the two main physiological processes that are fundamental to oxygen-dependent life. The test has affirmed its critical place in the evaluation of
Grading obstructive lung disease using tomographic pulmonary scintigraphy in patients with chronic obstructive pulmonary disease (COPD) and long-term smokers
V/P SPECT shows that long-term smokers in most cases have signs of ventilatory impairment and airway obstruction not shown by spirometry, both of which correlate with GOLD stage.
The added value of hybrid ventilation/perfusion SPECT/CT in patients with stable COPD or apparently healthy smokers. Cancer-suspected CT findings in the lungs are common when hybrid imaging is used
In COPD patients and long-time smokers, hybrid imaging had added value compared to V/P SPECT alone, by identifying patients with lung malignancy and more clearly identifying emphysema.
Methodology for ventilation/perfusion SPECT.
Ventilation/perfusion single-photon emission computed tomography (V/Q SPECT) is the scintigraphic technique of choice for the diagnosis of pulmonary embolism and many other disorders that affect lung
Ventilation-perfusion imbalance and chronic obstructive pulmonary disease staging severity.
Pulmonary gas exchange abnormalities in COPD are related to FEV(1) across the spectrum of severity, suggesting that COPD initially involves the smallest airways, parenchyma, and pulmonary vessels with minimal spirometric disturbances.
Assessment of ventilation inhomogenity with Krypton SPECT and planar imaging
In 29 chronic obstructive pulmonary disease patients and nine lung healthy volunteers, visual scoring of extent and severity of ventilation defects was reproducible and the correlation to pulmonary function was better with SPECT than planar imaging.
Lung perfusion scintigraphy prior to lung volume reduction surgery.
The combined information from CT and LPS are superior in assessing emphysema heterogeneity prior to LVRS, compared to classification based only on computed tomography.
Assessment of pulmonary neutrophilic inflammation in emphysema by quantitative positron emission tomography.
Quantitative FDG PET-CT has a potential role as an imaging biomarker in mechanistic and interventional studies in patients with usual COPD and AATD, and the data support previous evidence of distinct functional characteristics of neutrophils in COPD.
Hyperpolarised 3He MRI and 81mKr SPECT in chronic obstructive pulmonary disease
HP 3HeMRI provides detailed ventilation distribution images and defect scores are comparable on HP 3He MRI and 81mKr SPECT, and new insights into the regional pulmonary microstructure via the apparent diffusion coefficient measurements are provided by HP 3 he MRI.
Predicting the Response to Lung Volume Reduction Surgery Using Scintigraphy
This quantitative method of scintigraphy could provide an excellent reflection of surgical efficacy as well as predict the surgical outcome and provides a mechanistic explanation for the differential improvement between the histopathological subtypes of emphysema following surgery.
