This feasibility study investigated whether an ultra-low dose CT (ULDCT) chest protocol on PCD CT, with a dose comparable to chest radiographs, could be developed to detect gross lung abnormalities in children.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and methods<\/jats:title>\n                    <jats:p>This ethics-approved retrospective study consisted of two parts: (1) development of a ULDCT chest protocol using an anthropomorphic phantom and (2) qualitative evaluation of these scans performed in 24 consecutive patients (&lt;\u200916 years) for various indications. Two paediatric radiologists assessed diagnostic quality for six chest pathologies using a 3-point Likert scale. Radiation dose metrics were extracted from a dose management system, and effective doses (ED) were calculated using age-appropriate conversion factors. Statistical analysis included mainly descriptive calculations. Doses were compared with routine chest radiography.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The Lungman phantom was scanned using 5 different protocols. The optimal settings were identified as Sn100 kVp, 2 mAs and pitch 1.5, yielding an ED of 14 \u00b5Sv. All paediatric scans were assessed as acceptable, but a preference for an increased dose protocol was given to rule out interstitial lung disease or bronchiectasis. The mean total ED from the localiser and ULDCT of the chest was 11.6 [IQR: 10.9\u201312.8] \u00b5Sv compared to 8.2 [IQR: 6.2\u201313.6] \u00b5Sv for standard chest radiography.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Our PCD ULDCT chest protocol, approaching chest radiograph doses, is promising for (follow-up of) focal abnormalities and follow-up imaging of known chest pathology in children.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Key Points<\/jats:title>\n                    <jats:p>\n                      <jats:list list-type=\"bullet\">\n                        <jats:list-item>\n                          <jats:p>\n                            <jats:bold>Question<\/jats:bold>\n                            Can the technique of photon-counting detector CT result in radiation dose reduction, while achieving adequate image quality?\n                          <\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>\n                            <jats:bold>Findings<\/jats:bold>\n                            An ultra-low dose CT chest protocol was developed with a comparable dose to a single chest radiograph.\n                          <\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>\n                            <jats:bold>Relevance statement<\/jats:bold>\n                            The ultra-low dose CT chest protocol is promising in the setting of (follow-up of known) focal chest abnormalities, long-term follow-up after congenital diaphragmatic hernia repair and follow-up of interstitial lung disease in children.\n                          <\/jats:p>\n                        <\/jats:list-item>\n                      <\/jats:list>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1186\/s41747-026-00783-2","type":"journal-article","created":{"date-parts":[[2026,9,8]],"date-time":"2026-09-08T13:30:40Z","timestamp":1788874240000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Next-gen paediatric imaging: ultra-low dose chest photon-counting CT approaching chest radiograph doses"],"prefix":"10.1186","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-4579-1507","authenticated-orcid":false,"given":"Ione","family":"Limantoro","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kwinten","family":"Torfs","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joke","family":"Binst","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marijke","family":"Proesmans","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luc","family":"Breysem","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hilde","family":"Bosmans","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Aertsen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,9,8]]},"reference":[{"key":"783_CR1","doi-asserted-by":"publisher","first-page":"2426","DOI":"10.1007\/s00330-016-4566-1","volume":"27","author":"JM Meulepas","year":"2017","unstructured":"Meulepas JM, Smets AMJB, Nievelstein RAJ et al (2017) Trends and patterns of computed tomography scan use among children in The Netherlands: 1990\u20132012.
