|April 1, 1979
Summary
A new radioaerosol administration system reduces large aerosol droplets, preventing abnormal deposition in airways. This improved system uses an inexpensive reservoir bag for safer, more effective aerosol delivery in nuclear medicine.
Area of Science:
- Nuclear Medicine
- Respiratory Medicine
- Biomedical Engineering
Background:
- Abnormal hyperdeposition of inhaled aerosols in large airways is linked to droplets larger than 2.0 microns.
- Current radioaerosol administration systems may contribute to this issue.
Purpose of the Study:
- To develop an improved radioaerosol administration system.
- To reduce the prevalence of large aerosol droplets (>2.0 micron) during administration.
Main Methods:
- Interposed a reservoir-setting bag in the aerosol delivery line between the nebulizer and the patient.
- Utilized inexpensive, commercially available components.
Main Results:
- The new system effectively reduces the number of droplets larger than 2.0 micron in diameter.
- The system is easily assembled in nuclear medicine services.
Conclusions:
- The improved radioaerosol administration system offers a cost-effective solution to minimize abnormal airway deposition.
- This system enhances the safety and efficacy of inhaled aerosol delivery in nuclear medicine procedures.

01:30Radiological Investigation II: MRI and Ventilation Perfusion Scan
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
