Neuroradiology Flashcards
1
Q
- A native head X-Ray
A
– Has very low sensitivity and is becoming less frequently used
2
Q
- For which of the following indications is CT not appropriate? -
A
Spinal pathology
3
Q
- Fresh intracranial haemorrhage appears on a native CT -
A
As a hyperdense lesion
4
Q
- When a stroke is suspected, the first method of choice is -
A
Native CT of the head
5
Q
- What types of lesions in the brain are hyperdense on a native CT? –
A
Calcifications, hemorrhagic contusion and epidural bleeding
6
Q
- The most sensitive imaging method for displaying the CNS structures is -
A
MRI
7
Q
- Acute MRI can be indicated for -
A
Suspected spinal cord injuries
8
Q
- Which of these brain examinations lasts the longest? -
A
MRI
9
Q
- MRI should be the first-choice method for which brain areas? -
A
The sellar region and the brainstem
10
Q
- Head CT is ideal for -
A
Evidence of intracranial haemorrhage
11
Q
- Why is FLAIR sequence on MRI is used in neuroradiology? -
A
Due to the suppression of fluid signal we distinguish better T2 hypersignal pathologies
12
Q
- For the evaluation of pathologies near the ventricular system on MRI, it is best to use -
A
FLAIR
13
Q
- Which sequence is ideal for displaying pathologies of white matter on MRI? -
A
FLAIR
14
Q
- Which sequence in brain MRI is sensitive to hemoglobin breakdown products (and thus, for example, is good for hematoma diagnosis)?
A
- T2*
15
Q
- Which sequence is best for evaluating areas rich in fat? -
A
