The standard radiological examination of the chest and the X-ray are the first level of diagnosis in the study of diaphragm motility; these methods are limited and require integration by other diagnostic techniques, among which the Real Time and Time Motion mode (TM-mode) echography; these are particularly useful as they improve the sensitivity and specificity of the study. We examined 21 patients due for OLT, recording all diaphragmatic motility variations before and after the operation on day I, II, III and VII achieved by means of the TM-mode echography, comparing them with the corresponding standard X-rays. The correlation parameters used were presence/absence of pleural effusion (sensitivity: 100% US versus 64% radiology) and hypoventilation/atelectasis (85% sensitivity with 15% of false negatives during the ultrasound). In 7 cases the ultrasound showed a decrease in the diaphragmatic variations without any radiological finding. We believe that US can usefully support the traditional X-ray in early follow-up within these patients.
