MRI is superior to PET in the evaluation of primary or metastatic brain tumors.

Considerations for successful SPECT imaging of the brain include:

A technologist neglects to give a patient potassium perchlorate before injection with 20 mCi of 99mTc pertechnetate. How will this affect the static BRAIN images taken at 1 hour after injection?

The purpose of placing an elastic band around a patient’s head just above the orbits during a brain flow study is to:

After injection of F-18 flobetapir imaging should begin in:

Normally Tc99m Tc04- cannot cross the BBB.

What is the typical scintigraphic pattern of an interictal seizure focus on cerebral perfusion imaging?

A 11 mCi source of Thallium 201 in a volume of 5 ml, calibrated for June 10, at 12 noon, EST, was received on June 9. What would be the concentration on June 9, at 1:00 PM EST?

The central nervous system is made up of the:

Radionuclide cisternography is used for determination of all of the following EXCEPT
