Abstract
Objective To compare the diagnostic value of craniocerebral ultrasound with that of diffusion weighted imaging ( DWI )in premature infante with periventricular leukomalacia ( PVL ). Methods Diagnostic ultrasound and DWI were performed on premature infants with PVL. Results The positive rate of early detecting PVL in premature infants differed significantly between craniocerebral ultrasound and DWI ( 20.8% for craniocerebral ultrasound vs. 52.6% for DWI; x2=10.93, P< 0.01 ). Conclusions DWI is more sensitive than craniocerebral ultrasound in the ealy diagnosis of PVL in premature infants. Premature infants should receive DWI as early as possible ( within 1 week after birth). Key words: Periventricular; Leukomalacia; Premature infant; Ultrasound; DWI; Comparative study
