Answer to Question 1

a. be at risk for depression herself.

Answer to Question 2

The MRI measures variations in magnetic fields. It then computes and depicts cross sections of organs such as the brain with great clarity. It is noninvasive and allows for visualization of all but the tiniest brain structures. Its major problem is the claustrophobic reaction some people have to the procedure. PET scans track substances as they are metabolized by the brain. They can show how the brain is functioning. They can help identify areas that aren't functioning normally that might not be obvious anatomically. Their major problem is low-fidelity pictures that have so far limited their value. The fMRI measures changes in blood flow in the brain. It is possible to map ongoing psychological activity and show which areas of the brain are involved in different activities. However, like MRIs, these are very sensitive to movement, which can cause false results. Also fMRIs are often very hard to interpret.
