During the last decades, researchers have proposed CAD systems in several medical domains achieving promising results.\n<\/jats:p>\n                <jats:p>CAD systems play an important role in digital pathology supporting pathologists in analyzing biopsy slides by means of standardized and objective workflows. In the proposed work, we designed and tested a novel CAD system module based on image processing techniques and machine learning, whose objective was to classify the condition affecting renal corpuscles (glomeruli) between sclerotic and non-sclerotic. Such discrimination is useful for the biopsy slides evaluation performed by pathologists.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>We collected 26 digital slides taken from the kidneys of 19 donors with Periodic Acid-Schiff staining. Expert pathologists have conducted the slides preparation, digital acquisition and glomeruli annotations. Before setting the classifiers, we evaluated several feature extraction techniques from the annotated regions. Then, a feature reduction procedure followed by a shallow artificial neural network allowed discriminating between the glomeruli classes.\n<\/jats:p>\n                <jats:p>We evaluated the workflow considering an independent dataset (i.e., processing images not used in the training procedure). Ten independent runs of the training algorithm, and evaluation, allowed achieving MCC and Accuracy of 0.95 (\u00b1\u20090.01) and 0.99 (standard deviation\u2009&lt;\u20090.00), respectively. We also obtained good precision (0.9844\u2009\u00b1\u20090.0111) and recall (0.9310\u2009\u00b1\u20090.0153).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Results on the test set confirm that the proposed workflow is consistent and reliable for the investigated domain, and it can support the clinical practice of discriminating the two classes of glomeruli. Analyses on misclassifications show that the involved images are usually affected by staining artefacts or present partial sections due to slice preparation and staining processes. In clinical practice, however, pathologists discard images showing such artefacts.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12911-021-01650-3","type":"journal-article","created":{"date-parts":[[2021,11,1]],"date-time":"2021-11-01T11:03:53Z","timestamp":1635764633000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["A neural network for glomerulus classification based on histological images of kidney biopsy"],"prefix":"10.1186","volume":"21","author":[{"given":"Giacomo Donato","family":"Cascarano","sequence":"first","affiliation":[]},{"given":"Francesco Saverio","family":"Debitonto","sequence":"additional","affiliation":[]},{"given":"Ruggero","family":"Lemma","sequence":"additional","affiliation":[]},{"given":"Antonio","family":"Brunetti","sequence":"additional","affiliation":[]},{"given":"Domenico","family":"Buongiorno","sequence":"additional","affiliation":[]},{"given":"Irio","family":"De Feudis","sequence":"additional","affiliation":[]},{"given":"Andrea","family":"Guerriero","sequence":"additional","affiliation":[]},{"given":"Umberto","family":"Venere","sequence":"additional","affiliation":[]},{"given":"Silvia","family":"Matino","sequence":"additional","affiliation":[]},{"given":"Maria Teresa","family":"Rocchetti","sequence":"additional","affiliation":[]},{"given":"Michele","family":"Rossini","sequence":"additional","affiliation":[]},{"given":"Francesco","family":"Pesce","sequence":"additional","affiliation":[]},{"given":"Loreto","family":"Gesualdo","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3088-0788","authenticated-orcid":false,"given":"Vitoantonio","family":"Bevilacqua","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2021,11,1]]},"reference":[{"key":"1650_CR1","doi-asserted-by":"crossref","unstructured":"Neuen BL, Chadban SJ, Demaio AR, Johnson DW, Perkovic V.
