1
Q

Best modality for cord evaluation
* CT
* MRI
* MRA
* X-ray

A

MRI

Spinal cord and soft-tissue injuries are best evaluated by magnetic resonance imaging (MRI), whereas spinal fractures are better characterized by computed tomography (CT).

Q

Q4: What is the arterial supply of the infarcted lobe?
A. Anterior cerebral artery
B. Middle cerebral artery
C. Posterior cerebral artery
D. Basilar artery

A

B. Middle cerebral artery

Middle cerebral artery (MCA)

Supplies Portion of the frontal lobe and
Lateral surface of the temporal and parietal lobes
This includes the primary motor and sensory areas of the face, throat, hand and arm, and in the dominant hemisphere, the areas for speech

The infarcted regions encompass the right parietal and temporal lobes, as well as portion of the right frontal lobe and the right lentiform nucleus that are supplied by the middle cerebral artery (MCA).
