In a lung ventilation study with 99mTc-pentetate aerosol, which statement is incorrect?

In a lung ventilation study using 99mTc-pentetate aerosol, it is important to correctly understand how the imaging process works. The statement indicates that the patient is imaged while inhaling particles from the nebulizer, which suggests that imaging occurs simultaneously during the inhalation process. However, in practice, the imaging is typically performed after the patient has completed the inhalation of the aerosol.

During a lung ventilation study, the aerosol is nebulized, and the patient breathes in the radioactive particles. Following this inhalation phase, imaging is done to assess how the particles have distributed within the lungs. This allows for a clear visualization of lung ventilation patterns.

Other statements accurately reflect proper protocol in handling the equipment and patient during the study. For instance, disposing of the facemask, tubing, and nebulizer as radioactive waste acknowledges the safety measures in handling and disposing of radioactive materials. The act of disconnecting the patient from the nebulizer after inhalation is a standard procedure to ensure safety and avoid unnecessary exposure to radiation. Additionally, obtaining multiple projections from a single dose helps to provide comprehensive evaluation and can enhance the diagnostic quality of the imaging.

Understanding the sequence of actions in the lung ventilation study is crucial for accurate results and patient safety
