In Alzheimer’s disease, decreases in perfusion and metabolism occur in the

Ictal SPECT studies require an injection of a radiopharmaceutical:

A radiopharmaceutical kit is prepared at 11:00 AM with 5 ml of Tc99m Pertechnatate from generate eluate that is calibrated for 610 mCi/5 at 5:00 AM. How much activity will the kit contain?

If Tc99m DTPA, Tc99m04-, or Tc99mGH are seen to accumulate outside of the cerebral sinus system, then we know that the patient has a breakdown of the BBB.

Which of these radiopharmaceuticals will cross the intact BBB?
