As for me I think it's okay.Because QR just want to know if you have scoliosis or what is the degrees of your spine if it is a bit curved. Like for me,its 6 degrees which should be fine as it is not classified or to be considered as scoliosis.
Since your doctor wrote that " the thoracic vertebrae and disc spaces are normal with no scoliosis seen",I think that it totally interprets that your spine is okay.
Dont worry if Qatar wants more details,they will email you back and ask for it
