Jack is injected with a small amount of radioactive glucose and then lies in a scanner.He is given a task-to think about his favorite song-as the scanner records the movement and location of the glucose his brain A computer analyzes the data and produces a color-coded image of his brain activity. Jack is receiving the imaging technique called __ functional MRI (fMRI) electr encephalograph (EEG) computerized tomography (CT)scan A positron emission tomography (PET)

## Step 1<br />The problem describes a process where a person, Jack, is injected with a small amount of radioactive glucose and then asked to think about his favorite song. The scanner records the movement and location of the glucose in his brain. A computer then analyzes this data and produces a color-coded image of his brain activity. <br /><br />## Step 2<br />This process is a description of a specific type of brain imaging technique. The options provided are functional MRI (fMRI), electroencephalograph (EEG), computerized tomography (CT) scan, and positron emission tomography (PET).<br /><br />## Step 3<br />The key to identifying the correct answer is the use of radioactive glucose. This is a characteristic of the PET scan, which uses a radioactive substance called a tracer to look for disease in the body. The tracer is usually a two-step process. First, it is injected into the bloodstream. Then, it is absorbed by the organs and tissues. The PET scanner detects the radiation given off by the tracer and uses it to create detailed pictures of the inside of the body.
