Answer:
The best diagnostic procedure for Francine is to perform a pituitary MRI.
Explanation:
In medicine, a diagnosis is the act of determining and knowing the nature of a disease by observing its symptoms and signs. The term diagnostic also corresponds to the name by which the doctor qualifies the disease according to the detected signs, that is, the name given to the conclusion itself.
The diagnosis is made through tools and examinations where the doctor can visualize what is happening with the patient's organism and reach a conclusion.
In Francine's case, the doctor suspects that she has a tumor in the pituitary gland, which is a structure in the brain. To come to a conclusion about this, the doctor will need to visualize the region of the brain where this gland is located. The best way to do this is through an MRI.
Often the tumor is detected when the patient performs an MRI of the skull, allowing the doctor to view all regions of the brain.
