Nonuniform distributions of lung perfusion scintiscans obtained by SPECT were quantified to
supplement qualitative lung scintiscans. A total of 126 lung perfusion scintigraphy …

The diagnosis of pulmonary embolism (PE) remains one of the most difficult in clinical
medicine, and the diagnostic value of lung scintigraphy has been questioned. To evaluate …

Purpose Respiratory gated perfusion single photon emission computed tomography
(SPECT) was applied to reduce respiratory lung motion effects and to reliably assess …

Ventilation and perfusion lung imaging with SPECT/CT permits accurate delineation of the
individual lobes of the lungs using the CT images for use in ascribing the relative functional …

The aim of the present study was to develop and evaluate a method for semi‐quantification
of ventilation‐to‐perfusion ratios in small regions in planar pulmonary scintigrams using …

One of the main problems encountered in the analysis of ventilation/perfusion (V/P) lung
scans for the diagnosis of pulmonary embolism (PE) is difficulty in assessing the size of the …

Perfusion and ventilation abnormalities created by pleural effusions can interfere with the
interpretation of the lung scan. This retrospective study identified and evaluated the …

Ventilation‐perfusion scintigraphy is an established procedure for the investigation of lung
disease. Perfusion scans are commonly obtained with ay‐camera following injection of …

METHOD The ventilation-perfusionlung scintigram. An intra venous injection of 2 mCi of Tc-
99m-labeled macroaggregated albumin was given with the subject supine and breathing …
