This is not quite a drive-by nomination but the reviewer has only made one small change to the article before nominating, and has not addressed its more significant issues in need of cleanup.


 * The article is not well structured: there are many sections, but the overall section hierarchy does not make sense.


 * The lead has too many paragraphs, and makes claims that are not found anywhere in the text of the article. ✅


 * The first paragraph of the "Lungs" section is unsourced, as is the first bullet point of the "Cardiac" section and the entire "Abdominal and pelvic" and "Biomechanical use" sections. ✅


 * The "Advantages" section has been peppered with many "citation needed" tags since 2020. ✅


 * The last 1 1/2 paragraphs of "Abdominal and pelvic" and "Contrast reactions" are unsourced.


 * The "Process" section is a huge undigestible paragraph that is mostly unsourced.


 * Sentences at the ends of "Geological use", "Contrast", "Scan dose", "Radiation dose units", "Effects of radiation", and "Presentation" are unsourced. ✅


 * The last paragraph of "Grayscale" and the last four paragraphs of "Multiplanar reconstruction and projections" are unsourced.


 * The entire "Volume rendering" section is unsourced. ✅


 * Several paragraphs in "Image quality" are unsourced. ✅


 * The "Etymology" section has three unsourced paragraphs, one with another stale "citation needed" tag. ✅


 * The "Types of machines" section is mostly unsourced. ✅

Overall, I think there may be a lot of excessive detail in the article. It needs to take a higher-level view of the subject.

As such, I think this meets WP:GAFAIL criteria #1 (it is a long way from being properly sourced) and #3 (it has large numbers of citation needed tags that are still valid). It was not ready for a GA nomination and should not be re-nominated until these issues are addressed.
