Also introduces anti-scatter grids and image receptors like screen-film systems and digital detection systems and ends with a few questions.

Sir, is each mammography tube different from the type of mammography? for example, do digital mammography siemens, fuji, hologic have different tubes?

Meri right side breast mein lump tha 5 years earlier uski surgery hui thi uske baad se mujhe right side breast mein pain, itching, numbness rehne lgi. Problem find out krne ke liye humne ab mammography krayi mammography both sides ki hui and after that dr. ne right side breast ka ultrasound bhi kiya unhone btaya ki ultrasound mein koi problem nhi h sab normal h but jab unhone mujhe report di usmein mammography mein sab normal likha hua h usg mein fibroadenosis in one side and impression mein fibroadenosis in bilateral breast likha hua h. Sir how is it possible jab ultrasound right side ka hua toh wo dr. Kaise keh sakte h fibroadenosis left side mein bhi h maine unse yhi baat puchi toh wo kehte h aapke breast x-ray se aise lag rha h but unhone mammography mein sab normal likh rkha h
And sir fibroadenosis ki wajah se agar problem hoti toh uski wajah se toh both sides problem rehni chahiye but mujhe only right side mein hi problem h
Sir please suggest me something what i have to do now. Am I right or wrong?
