Critical Reasoning (CR) | Re: Magnetic resonance Imaging(MRI)-a noninvasive diagnostic procedure ca

Understanding the argument -
Magnetic resonance Imaging(MRI)-a noninvasive diagnostic procedure can be used to identify blockages in the coronary arteries. - Fact
In contrast to angiograms-the invasive procedure customarily used -MRI's pose no risk to patients. - Fact
Thus to guarantee patient safety, in the attempt to diagnose arterial blockages ,MRI's should replace angiograms in all attempts at diagnosing coronary blockages. - Conclusion

Option Elimination -

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

B. MRI's were designed primarily in order to diagnose blockages in the coronary arteries - But "angiograms" could still be better? Isnt it? At best, it is out of scope. Our scope is limited to strengthening the conclusion, which is "MRIs should replace angiograms."

C. Angiograms reveal more information about the nature of blockage than a MRI can - Weakener

D. An MRI is just as likely as an angiogram to identify
