Q

Normally, we use contrast in the brain (T/F)

A

FALSE: it stays the same after contrast
Only pituitary glands and vessels enhance

Q

Wernicke is related to… speech
Broca is related to … speech

A
  • understanding
  • motor (knowing how to speak). If there is a problem here: AFASIA

They are connected, if there is a problem in the connection, no habrá congruencia entre lo que dice y lo que entiende.

Q

With MRI we can do functional imaging and identify the different areas of the brain (T/F)

A

True: to identify primary motor areas of the hand for example, if we have a tumour we do not see it.
We need the patient to cooperate, to see which area of the brain controls the movement (either speaking for Broca, or moving something for motor cortex).

31
Q

¿Qué técnica observamos?

A

RESONANCIA MAGNÉTICA

32
Q

For spinal cord imaging, we mainly use…

A

MRI (we see almost nothing with CT)

33
Q

What can we see in this image?

A

Iodinated contrast CT

34
Q

Techniques used in vascular radiological anatomy of the head and neck

A
  1. Doppler ultrasound: mostly for extracranial arteries (carotid arteries in the neck)
  2. Conventional angiography
  3. CT angiography (CTA, with iv contrast)
  4. MRI angiography (MRA)
    - No contrast: TOF and phase contrast (PC)
    - With iv contrast.
35
Q

Technique used

A

Doppler ultrasound

36
Q

Technique used

A

Direct arteriography (contrast is used), only for treatment (for stenosis or thrombus)
IT IS NOT AN STATIC IMAGE, BUT A DYNAMIC STUDY

37
Q

For intracranial vessels, we usually use…

A

CT (mostly) with contrast, and MRI

38
Q

Cerebral arterial irrigation divided into:
- anterior circulation: …
- posterior circulation: …
Both originate from arterial branches of the …

A
  • CAROTID AXIS
  • VERTEBRO-BASILAR AXIS

aortic arch.

Vertebral arteries enter in transverse processes of…

A

42
Q

Why does the artery have this form?
