Basilar artery flow characteristics and color Doppler sonography findings in healthy infants

Aim: Transcranial​ ​Doppler​ ​(TCD)​ is a widely used method for the evaluation of vertebrobasilar system. There not neither consensus nor significant number publications about normal spectral Doppler waveform and resistance index (RI), peak systolic velocity (PSV), end diastolic (EDV) values basilar artery (BA). We aim to define PSV, EDV, RI BA via TCD in healthy infants. 
 Material Method: was evaluated from anterior fontanelle by creating sagittal coronal images. Color doppler ultrasonography (CDUS) examinations were performed placing cursor middle portion BA. recorded. Patients divided into 4 subgroups analyze change according age groups: (1) 0-120 days, (2) 121-180 (3) 181-270 (4) >271 days.
 Results: 115 infants included study. A weak positive correlation found between EDV age; meanwhile but negative present values. cannot find any sex CDUS parameters. Conclusion: age. No characteristics sex. pathologies are rare pediatric population, nevertheless knowing can help radiologists an appropriate assessment.
