Radioactive gases are useful for evaluating pulmonary ventilation because they allow
assessment of regional lung function in a physiologic, noninvasive manner. The most widely …

Krypton-81m gas, by virtue of its imaging characteristics, is often considered the “gold
standard” for ventilation scintigraphy but its use is restricted by its high cost and limited …

In 169 patients with suspected deep vein thrombosis (DVT), the incidence and clinical
feature of pulmonary embolism (PE) was prospectively studied by means of noninvasive …

Deposition distribution variability strongly influences data from radioaerosol mucus
clearance measurements. We investigated how one clearance measurement—the area …

In this article we describe a computer program to demonstrate ventilation-perfusion
relationships in the lungs, using 99m Tc-MAA and 81m Kr, with the patients sitting upright …

We have measured regional lung tidal volumes and functional residual capacities by
accumulating and framing iso-volumic images while the patient rebreathes 127 Xe. As the …

The applications of radionuclide techniques to the diagnosis and management of critically ill
patients are developing so quickly that the average clinician needs guidance on what is …

Die szintigraphische Untersuchung der Lungenbelüftung ist ein seit Jahrzehnten
etabliertesVerfahren zur Untersuchung der Atemwege bei obstruktiven und …

Currently accepted radioisotope techniques for determining regional perfusion and
ventilation in the lung are limited by their lack of resolution, superposition of three …

The purpose of this study is to develop a method to create new images, based on lung
verification and perfusion raw nuclear medicine images obtained from a gamma camera …
