A. Hyperdense

B. Hyperintense

C. Hypodense

D. Hypointense

Answer 8

Hyperdense

Question 9

Answer 11

True

Question 12

A. IT’s non-invasive and can examine vessels from origin

B. It has a high resolution

C. It does not use radiation

D. All of the above

Answer 12

IT’s non-invasive and can examine vessels from origin

Question 13

A. X-ray

B. Fluroscopy

C. MRI

D. Ultrasound

Answer 13

MRI

Question 14

In T1 weighted MRI, what does the CSF appear as?

A. Hyperintense/white

B. Hypointense/dark

C. Hyperdense/white

D. Hypodense/dark

Answer 14

Hypointense/dark

Question 15

Which of the following scenarios woulr the T1 vs T2 weighted MRI be good for?

A. Visualizing pathology

B. Imaging normal anatomy

Answer 15

Imaging normal anatomy

becuase structures will appear white/hyperINTENSE

A. Edema

B. Swelling

C. Absecesses

D. All of the above

Answer 16

Edema (swelling)

Abscesses

B. Expensive

C. Learning-curve

D. Uses radiation

Answer 17

Learning-curve
