Abstract：
The purpose of this study was to understand the public perception of CT colonography (CTC) in comparison with optical colonoscopy as a colorectal cancer screening technique.
In this observational study, all English-language tweets from January 1, 2015, until September 1, 2021, containing terms related to CTC and terms related to optical colonoscopy were collected. The tweets were given sentiment scores using Twitter-roBERTa-base, a natural language processing model. These scores were then used to classify tweets into positive, neutral, and negative categories. The numbers of negative, positive, and neutral tweets were tabulated.
A total of 4,709 tweets from 2,194 users relating to CTC were collected. Of these tweets, 9.81% were negative, 68.52% were neutral, and 21.63% were positive. In comparison, a total of 445,969 tweets from 261,209 users were collected relating to optical colonoscopy. Of these tweets, 31.8% were negative, 51.3% were neutral, and 16.9% were positive.
The public awareness of CTC remains limited in comparison with optical colonoscopy, with Twitter volume relating to CTC being about 1% the volume for optical colonoscopy. There was a higher proportion of negative tweets regarding colonoscopy. The lower proportion of negative tweets regarding CTC may be helpful in encouraging its use as an alternative to optical colonoscopy, with the aim of increasing uptake of colorectal cancer screening.

摘要：
目的：我们研究的目的是了解公众对CT结肠成像与光学结肠镜作为结直肠癌筛查技术的看法。
方法：在这项观察性研究中，我们收集了2015年1月1日至2021年9月1日的所有英语推文,其中包含与CT结肠造影(CTC)相关的术语和与光学结肠镜检查相关的术语.这些推文使用Twitter-roBERTa-base获得了情绪评分，自然语言处理模型。然后使用这些分数将推文分类为阳性，中性,和负面类别。负数的数量，积极的,和中性的推文被制成表格。
结果：共收集了来自2,194个与CTC有关的用户的4,709条推文。在这些推文中，9.81%为阴性,68.52%为中性,和21.63%为阳性。相比之下,共收集了来自261,209名用户的445,969条与光学结肠镜检查有关的推文.在这些推文中，31.8%为阴性，51.3%为中性,和16.9%为阳性。
结论：与光学结肠镜检查相比，公众对CT结肠成像的认识仍然有限，与CTC相关的Twitter体积约为光学结肠镜检查体积的1/100。结肠镜检查的阴性鸣叫比例更高。对CTC的阴性推文比例较低可能有助于鼓励其用作光学结肠镜检查的替代方法，目的是增加对大肠癌筛查的吸收。
