In children, give 14 mg/kg
The diffusible radiotracers, capable of crossing the blood-brain barrier by passive transport, are neutral, lipophilic and low molecular weight molecules
SUMMARY: The acetazolamide (ACZ) challenge test is a useful clinical tool and a reliable predictor of critically reduced perfusion
Diamox (Acetazolamide): Uses, Side Effects, and Dosages
Brain perfusion SPECT is a functional neuroimaging technique that allows noninvasive study of physiologic and physiopathologic events in the human brain
Currently, three CBF tracers are used for SPECT imaging in routine clinical practice: Tc-99m hexamethyl-propyleneamine-oxime (HMPAO), Tc-99m ethyl-cysteinate dimer (ECD), and I-123-labeled N-isopropyl-p-iodoamphetamine (IMP)
However, for patients who have had cerebrovascular accidents in the past and are at increased risk for stroke, acetazolamide-challenged SPECT brain imaging may
lightheadedness or blurred vision
A baseline brain perfusion study without acetazolamide is performed one or more days later
Review Diamox brain SPECT protocols for acquisition and data assessment
Some tests, such as a single photon emission computed tomography (SPECT Brain SPECT can be complemented with pharmaceutical agents that enhance regional cerebral blood flow, such as acetazolamide (carbonic anhydrase)
