Technetium-99m diethylenetriaminepentaacetic acid ([99mTc] DTPA) radioaerosol scans
performed on 21 consecutive artificially ventilated patients were compared to 50 similar …

We have compared the distribution in the lungs of submicronic aerosols of either Tc-99m
sulfur colloid or Tc-99m DTPA immediately after inhalation with the distribution 20 minutes …

Pulmonary ventilation and perfusion scintigraphies were performed using 99m Tc-MAA, 81m
Kr, and 99m Tc-DTPA aerosol in a patient with asthma. Lung perfusion scintigraphy and …

Satisfactory agents for ventilation imaging are not widely available. Access to Kr-81m is
limited and image quality with Xe-133 is poor, so attention is being focused on radioaerosols …

Papers on deposition pattern analyses of radio-aerosol lung scans are few and not easy to
interpret as there is a general lack of technical standardization and the number of patients …

Ventilation scintigraphy of the lung, obtained with sufficiently small 99mTc-labelled aerosol
particles, provides an image of ventilation distribution that is acceptable in clinical routine …

Pulmonary embolism demands rapid and accurate diagnosis. And ventilation imaging has
greatly improved the diagnostic accuracy of pulmonary embolism in addition to perfusion …

Because of several limitations associated with conventional ventilation scintigraphy using
radioactive gases, an alternative method appears desirable. This paper describes in detail …
