HAPPY TEACHERS DAY

HAPPY TEACHERS DAY

MY SALUTATION TO ALL TEACHERS

I have learned silence from the talkative, toleration from the intolerant, and kindness from the unkind; yet, strange, I am ungrateful to those teachers. 
Khalil Gibran

Thanks teacher for inspiring me to do well in life.
Whatever I have achieved in life is because of you.
Happy Teacher's Day!

FREQUENCY OF TNANSDUCER FOR SKIN USG

---Frequency of transducers used for examination of skin -----20 to 100 MHz ( depth of field 1 mm or less ,and in -plene resolution  is as high as < 50 micrometere).
---An adequate assesment of subcutaneous tissue can be made by means of transducers of 5 to 15 MHz.
--At 20 MHz ,the echogenic dermis can be separated from the hypoechoic subcutaneous fat .
---
----The thick subcutaneous fat of the lateral part of the proximal thigh can be examined by transducer of as low frequency as 5 MHz.
---Subcutaneous tissue appears as  USG as a discrete hypoechoic layer characterised by a hypoechoic background of fat and hyperechoic linear echoes correspomding to a web of connective tissue
----subcutaneous vein and nerve can be appreciated on USG.
----Normal Lymphatics in the subcutaneous tissue cannot be visualised with US.
