Abstract
- A previous 1999 to 2010 analysis showed that Asia is the only continent publishing more congenital heart CT articles than those concerning MR imaging. A 1999 to 2020 follow-up, 21-year analysis shows the same trend. Among the 16 countries that published more than 21 congenital heart CT and 21 congenital heart MR articles in this period, South Korea, Taiwan, Japan, and China were the only four countries with CT/MR ratios of at least 1. As compared with 12 countries with CT/MR publication ratios of less than 1, these four countries have significantly lower health expenditures per capita (2395 USD vs. 5225 USD; p=0.029). On the citation map of congenital heart CT, South Korea, Taiwan, and Japan pioneered this field, but recent growth in the prominence of this imaging modality has been observed in China. Several researchers are at the center of the citation map, indicating the key roles they play in the accumulation and growth of the literature.
