7 Central Nervous System Scintigraphy 6725) A technologist neglects to give a patient potassiumperchlorate before injection with 20 mCiof 99m Tc pertechnetate. How will this affect the staticbrain images taken at 1 hour after injection?a. thyroid activity may be seenb. choroid plexus may be seenc. salivary glands may be seen26) Radionuclide angiography is most commonly used to:a. locate neoplasmsb. investigate brain perfusionc. evaluate cerebrovascular reserved. confirm brain death27) In which area is the radiopharmaceutical not visiblein a normal cisternogram?a. basal cisternsb. cerebral convexitiesc. lateral ventriclesd. sylvian fissure28) CSF dynamics are studied following administrationof 111 In DTPA:a. via intravenous injectionb. via intradermal injectionc. via intraperitoneal injectiond. via intrathecal injection29) What is the usual dose for a radionuclide cisternogramin adults?a. 5 mCi of 111 In DTPAb. 100 µCi of 111 In DTPAc. 500 µCi of 111 In DTPAd. 2.5 mCi of 111 In DTPA
687 Central Nervous System Scintigraphy30) What is the purpose of pledget placement in suspectedCSF leak?a. to make the patient more comfortable duringsubarachnoid punctureb. to alter the biodistribution of the radiotracerc. to test them for contamination suggesting thepresence of leaking CSF in the nose or earsd. to avoid contamination of the scintillation detectionsystem31) Why is 111 In DTPA preferred over 99m Tc DTPAfor cisternography in adults?a. because it has lower energy photonsb. because it has 2 photopeaksc. because it has a longer half life allowing delayedimagingd. because it has a superior biodistribution32) 99m Tc labeled lipophilic radiopharmaceuticals arepreferable to radioiodinated amines because:a. they are more rapidly extracted from the bloodstreamb. they deliver a lower radiation dose to patientsc. administered activity is higher, providing superiorimagesd. all of the abovee. b and c only33) Considerations for successful SPECT imaging of thebrain include:a. minimizing sensory stimulation during injectionb. minimizing patient to detector distancec. immobilizing the patientd. all of the abovee. b and c only
