In the diagnosis process, radiologists play an important role by examining numerous radiology exams to identify different types of nodules. To aid the clinicians\u2019 analytical efforts, computer-aided diagnosis can streamline the process of identifying pulmonary nodules. For this purpose, medical reports can serve as valuable sources for automatically retrieving image annotations. Our study focused on converting medical reports into nodule annotations, matching textual information with manually annotated data from the Lung Nodule Database (LNDb)\u2014a comprehensive repository of lung scans and nodule annotations. As a result of this study, we have released a tabular data file containing information from 292 medical reports in the LNDb, along with files detailing nodule characteristics and corresponding matches to the manually annotated data. The objective is to enable further research studies in lung cancer by bridging the gap between existing reports and additional manual annotations that may be collected, thereby fostering discussions about the advantages and disadvantages between these two data types.<\/jats:p>","DOI":"10.1038\/s41597-024-03345-6","type":"journal-article","created":{"date-parts":[[2024,5,17]],"date-time":"2024-05-17T12:02:13Z","timestamp":1715947333000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["LNDb v4: pulmonary nodule annotation from medical reports"],"prefix":"10.1038","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9546-4227","authenticated-orcid":false,"given":"Carlos A.","family":"Ferreira","sequence":"first","affiliation":[]},{"given":"C\u00e9lia","family":"Sousa","sequence":"additional","affiliation":[]},{"given":"In\u00eas","family":"Dias Marques","sequence":"additional","affiliation":[]},{"given":"Pedro","family":"Sousa","sequence":"additional","affiliation":[]},{"given":"Isabel","family":"Ramos","sequence":"additional","affiliation":[]},{"given":"Miguel","family":"Coimbra","sequence":"additional","affiliation":[]},{"given":"Aur\u00e9lio","family":"Campilho","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2024,5,17]]},"reference":[{"key":"3345_CR1","first-page":"209","volume":"71","author":"H Sung","year":"2021","unstructured":"Sung, H. et al.
