The new heart scans offer patients significant benefits. They can be completed in a fraction of the time required for an angiogram, with no recovery time necessary. Furthermore, the scans are more sensitive and can identify problem areas that an angiogram might not perceive. However, heart scans use more radiation than most diagnostic procedures, and can cause undue concern over and treatment for the harmless abnormalities often picked up by such sensitive technology.
Which of the following conclusions is best supported by the statements above?
The passage that heart scans take less time than angiograms and do not require recovery time. They are also more sensitive than
angiograms. But they use more radiation than other diagnostic procedures. And finally, their sensitivity can result in detection of harmless abnormalities that may worry patients. We are asked to find among the choices a conclusion that can be drawn on the basis of that information.
A .Incorrect- states that a heart scan is safer than an angiogram. We are given no information about the relative safety of the procedures.
B. states that patients should not be concerned about heart abnormalities that appear in a heart scan. This misrepresents the information in the passage. The passage simply stated that the scans may pick up harmless abnormalities, not that all abnormalities are harmless. Incorrect.
C. states that a heart scan could result in indirect harm by causing a patient to undergo risky unnecessary procedures. This is supported by the passage, which states that the scans could result in undue concern and treatment. Correct.
Choice D states an angiogram is the appropriate treatment for most patients. The information in the passage does not support this. In fact, if anything, the passage would seem to support the contradictory assertion that heart scans are more appropriate for most patients. Incorrect.
Choice E states that a heart scan is more expensive. We are given no information about cost. Incorrect.
