Task: Sentence Composition
Input (English): The story provides the cost of the CT scan as well as angiography. However, the story should have discussed insurance coverage for the scans. The story describes the percentage of patients with blockages that were identified with either the CT scan or the angiogram. The story should have also described the probability of having blockages with a positive scan (positive predictive value). This is the more important piece of information to a consumer. Also not described in the story is whether the CT scans had any impact at all on downstream outcomes, such as heart attacks, deaths, or procedures. The story correctly describes radiation exposure as one of the harms of the heart CT. The story could have described other harms, such as the implications of false positive or false negative test results. The story adequately describes the design of the current study, including a criticism from one expert that the study "cherry-picked" patients to include in the study in order to maximize the findings. The story does not exaggerate the seriousness or prevalence of heart disease. However, the story could have been more clear about who the CT scans are intended for. The study in question was in those with suspected heart disease, not the assymptomatic or "worried well". The use of CT scans in the larger asymptomatic population is controversial. The story quotes multiple independent experts who provide valuable commentary on the implications of the new findings. The story mentions angiography as the alternative to the heart CT. The story clearly states that the CT scans are relatively new and available in many hospitals, however it is not clear how many hospitals have purchased these machines. The story adequately describes the novelty of the scans. Because the story quotes multiple experts, the reader can assume that the story did not rely on a press release as the sole source of information.
Output (English): ‘Super X-rays’ show promise for finding heart disease but produce high radiation dose
