Single Photon Emission<\/span><\/h2>\n

Computed Tomography <\/span><\/h2>\n
\n

Similar to PET, single photon emission computed tomography (SPECT) uses radioactive tracers and a scanner to record data that a computer constructs into two- or three-dimensional images. The tracer is what allows doctors to see how blood flows to tissues and organs & provide them with functional information of that particular organ which can be read together with other anatomical imaging information to manage the treatment of the patients in a better way.<\/p>\n

\n

A small amount of a radioactive drug is injected into a vein and a scanner is used to make detailed images of areas inside the body where the radioactive material is taken up by the cells. SPECT can give information about blood flow to tissues and chemical reactions (metabolism) in the body.<\/p>\n<\/div>\n

\n
What does a SPECT scan show?<\/span><\/h5>\n

A SPECT scan is primarily used to view how blood flows through arteries and veins in the brain. Tests have shown that it might be more sensitive to brain injury than either MRI or CT scanning because it can detect reduced blood flow to injured sites<\/p>\n

SPECT scanning is also useful for presurgical evaluation of medically uncontrolled seizures The test can be performed between seizures (interictal) or during a seizure (ictal) to determine blood flow to areas where the seizures originate.<\/p>\n
