yes. you have to take off the shirt because even non-radio-opaque objects (like buttons) can hide a tiny mass or mimic a mass. as far as a journal resource you will need to find that yourself. you are doing this project not me.
do we really need to remove our shirt during chest x ray even when we are not wearing any radioopaque material? . just asking opinion. this is for my final year project research. do we really need to remove our shirt during chest x ray even when we are not wearing any radioopaque material? . and if possible can u give me link that related to the journal of the procedure. thanks
