A case of hot spots observed on perfusion lung images is presented. This artifact is well
known, however, it is rarely seen in our experience. Although this artifact can occur if a faulty …

Perfusion lung scans are occasionally characterized by focal zones of apparent
hyperperfusion (" hot spots"). To investigate the frequency and significance of this …

A stripe sign in pulmonary perfusion imaging is reported to be predictive of the absence of
pulmonary embolism in the specific area of the stripe sign, and generally does not change …

Technical error is not usually considered among the many possible causes of false-positive
lung scans. A case is presented where the inadvertent injection of Tc-99m MAA through a …

A total of 47 patients who underwent both lung ventilation-perfusion scintigraphy and
pulmonary arteriography were evaluated for presence on the scintigram of perfusion defects …

A defect seen in the perfusion scan in a region of lung that is normally ventilated is usually
interpreted as indicating pulmonary vascular disease. Since the distribution of 99Tcm macro …

The lung scans were performed with a large field of view gamma camera. The ventilation
study was performed in the posterior projection, using 15— 20mCi (555— 740MBq) of …

Pulmonary perfusion patterns resulting from the use of commercially available MAA 131I
imaging procedures have been used widely in the last five years in an attempt to identify …
