The future of Neonatal Lung Ultrasound: validation of an Artificial
Intelligence model for interpreting lung scans. A multicentre
prospective diagnostic study.
Abstract
Background Artificial intelligence (AI) is a promising field in
the neonatal field. We focused on lung ultrasound (LUS), a
useful tool for the neonatologist. Our aim was to train a neural network
to create a model able to interpret LUS. Methods Our
multicentric, prospective study included newborns with gestational age
(GA) ≥ 33+0 weeks with early tachypnea/dyspnea/oxygen requirements. For
each baby, three LUS were performed: within 3 hours of life (T0), at
4–6 hours of life (T1) and in the absence of respiratory support (T2).
Each scan was processed to extract ROI used to train a neural network to
classify it according to the LUS score. We assessed sensitivity,
specificity, positive and negative predictive value of the AI model’s
scores in predicting the need for respiratory assistance with nasal
Continuous Positive Airway Pressure (nCPAP) and for surfactant, compared
to the “classical” scores. Results We enrolled 62 newborns
(GA=36±2 weeks). In the prediction of the need for CPAP, we found a
cut-off of 6 (at T0) and 5 (at T1) for both the classical nLUS and AI
score. In the prediction of surfactant therapy we found a cut-off of 9
for both scores at T0, at T1 the nLUS cut-off was 6, while the AI’s one
was 5. Classification accuracy was good both at the image and classes
level. Conclusions This is, to our knowledge, the first attempt
to use an AI model to interpret early neonatal LUS and can be extremely
useful for neonatologist in the clinical setting.
