Note:—5-point scale: 1 indicates nondiagnostic, cannot identify or rule out ventricular enlargement and shunt tube tip location; 2, will potentially miss mild ventricular enlargement and shunt tube tip location; 3, will probably not miss ventricular enlargement and shunt tube tip location; 4, most likely will identify all abnormalities with respect to ventricular enlargement and shunt tube tip; 5, can detect ventricular enlargement and shunt tube tip without diagnostic compromise.
