Summary

BACKGROUND: The aim of this study was to assess pulmonary deposition and distribution of radio-aerosol in obese and normal women, using 2-D planar scintigraphy. METHODS: after inhaling an aerosol of technetium labeled diethylenetriamine penteacetic acid (99mTc - DTPA) with an activity of 1 mCi in a total dose volume with normal saline of 2,5 ml using a vibrating mesh inhaler.
