The procedure was explained clearly. A changing room was provided which all my belongings were locked in during the scan. My dignity and comfort was ensured throughout.

I didn't feel I was welcomed, the receptionist didn't smile or really speak as I arrived and I didn't really appreciate having to wait in a very hot corridor. When Dr Ginwalla asked the receptionist to arrange some tests for me, the receptionist was very helpful.
