Brain Ultrasound question |

Dear Ask The Doctor: My 10 month old daughters ultrasound result of her brain came back with the result as 'subtle diffuse increase in parenchymal echogenicity seen bilaterally posteriorly'. Can you confirm if this is the same thing as a periventricular flare?? As one doctor has used the term 'flare' and another has not. many thanks Dear Emma: The transducer of the ultrasound machine generates high-frequency sound waves (typically 5-10 MHz) and directs them through body tissues via the probe held against the skin. Various probes and transducers are available for examination of different organs and body parts. The probe also contains a receiver to detect sound waves (called echoes) reflected from tissues, so “subtle diffuse parenchymal echogenicity” is just the sound waves received when they are reflected from the posterior brain tissue, most likely with no clinical connotation due to their subtle and diffuse nature. This finding is different of “periventricular flare”, the brain ventriculi are 2 cavities in a central position in the brain and the parenchymal echogenicity is in the posterior brain tissue .
