Question 1

Magnetic resonance imaging (MRI) – a noninvasive diagnostic procedure – can be used to identify blockages in

the coronary arteries. In contrast to angiograms – the invasive procedure customarily used – MRI’s pose no risk

to patients. Thus, to guarantee patient safety in the attempt to diagnose arterial blockages, MRI’s should

replace angiograms in all attempts at diagnosing coronary blockages.

Which of the following, if true, would most support the recommendation above?

Options :

A :

Angiograms can be used to diagnose conditions other than blockages in arteries.

B :

MRI’s were designed primarily in order to diagnose blockages in the coronary arteries.

C : Angiograms reveal more information about the nature of a blockage than an MRI can.

D :

An MRI is just as likely as an angiogram to identify an arterial blockage.

E : Some patients for whom an angiogram presents no risk are unwilling to undergo an MRI.
