Normal 99mTc-DTPA Ventilation Scan
Agent: Aerosolized 99Tc-DTPA
Adult Doses: 30 mCi* by Inhalation (* assumes that perfusion was done first)
Excretion: Renal Critical Organ: Bladder

  • Advantages of 99mTc-aerosols include being able to use on Ventilated patients, better imaging energy, and performance of the ventilation scan after the perfusion scan (can concentrate on perfusion abnormalities)
  • Should be able to differentiate from 133Xe study, as there is no wash-in or wash-out phase, and multiple projections are typically used
  • Note activity in the trachea; this should allow discrimination from perfusion study
These signals are relayed buying clomid online safe which then is by a number of such as medial preoptic and paraventricular nulcei.
