NPPB and hydrops fetalis: The LUS showed higher sensitivity ratio 1.2 (95% CI, 1.08–1.34; p < 0.001) compared with CxR, computerized tomography (CT), and echocardiogram [61,62,63,64,65,66] in the diagnosis of HF and using LUS with the clinical evaluation reduced diagnostic errors as compared to [CxR + Nt-proBNP] combination [67].
