It’s looks normal no need to worry !! And need detail evaluation

No, prominent vascular markings usually isn't significant enough to make a diagnosis. Xray just shows us a picture of your chest region. Need to know the exact symptoms to make a clear clinical diagnosis and correlate with the X-ray findings,,,for which you need to get a consult. Thank you for asking. Hope I was able to curb your doubt. Stay healthy. Stay home. :)
