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?

CSF communicates freely through the CNS. At what point after leaving the ventricles will CSF generally flow back to the ventricles?

The degree of Thallium uptake is proportional to the

In a Diamox challenge study, vascular disease will appear as decreased perfusion after the use of Diamox.

If an interthecal injection is made at the level of L2, at what time should the radiopharmaceutical appear to have ENTERED the ventricular cavities?

I123 ioflupane is used to:

The lumbar injection site is immediately scanned after radiopharmaceutical injection in radionuclide cisternography to
