Which brain imaging technique is most commonly used to study the neural basis of cognitive aging?
-
Magnetic resonance imaging (MRI)
-
Computed tomography (CT)
-
Positron emission tomography (PET)
-
Electroencephalography (EEG)
A
Correct answer
Explanation
Magnetic resonance imaging (MRI) is the most commonly used brain imaging technique to study the neural basis of cognitive aging due to its high resolution and ability to provide detailed images of brain structure and function.

-
Magnetic resonance imaging (MRI)
-
Computed tomography (CT) scan
-
All of the above
D
Correct answer
Explanation
All of the options listed are reproductive health technologies.
Which of the following is NOT a type of reproductive health technology?
-
Laparoscopy
-
Hysteroscopy
-
Colposcopy
-
Mammography
D
Correct answer
Explanation

How are nasal polyps diagnosed?
-
Physical examination of the nose
-
Nasal endoscopy
-
CT scan of the sinuses
-
All of the above
D
Correct answer
Explanation
Nasal polyps are diagnosed through a physical examination of the nose, nasal endoscopy, and a CT scan of the sinuses.

Audiometry
-
All of the above
E
Correct answer
Explanation
Otitis Media is diagnosed based on a physical examination, otoscopy (examination of the ear canal and eardrum), tympanometry (measurement of the movement of the eardrum), and audiometry (measurement of hearing).
How are fibroids diagnosed?
-
Pelvic exam
-
Ultrasound
-
MRI
-
All of the above
D
Correct answer
Explanation
Fibroids can be diagnosed through a pelvic exam, ultrasound, MRI, or a combination of these tests.
Which of the following is NOT a type of medical technology?
-
