Objective:
Congenital diaphragmatic hernia (CDH) has a poor prognosis, despite intensive management. The prognosis of CDH is correlated with hypoplastic lung, but it is difficult to measure the degree of hypoplasia. The aims of this study were, therefore, to examine the relationship between chest X-ray and prognosis, and to assess whether the radiographic findings were a good indicator of hypoplastic lungs in patients with CDH.
Study Design:
Fifty neonates with CDH were classified radiographically into apex and hilar types. To assess the differences in clinical course between these two groups, gestational age, birth weight, prenatal diagnosis, survival rate, requirement of extracorporeal membrane oxygenation (ECMO) therapy and lung area on X-rays were analyzed.
Results:
In all, 32 cases were of the apex type and 18 were hilar. The survival rate of the hilar group (33%) was significantly worse than that of the apex group (81%) (P<0.001). The hilar group required ECMO therapy more frequently than did the apex group.
Conclusions:
The present results show a significant correlation between survival rate and the findings of chest X-rays in CDH. Radiographic findings are thus a good clinical indicator of the prognosis of CDH in neonates.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
