Dysis is a Colposcopy system that uses a digital mapping software to improve the accuracy of diagnosis of lesions of the Cervix like CIN. Mr Razvi is the first gynaecologist to introduce Dysis in Essex and now runs Colposcopy clinics using this innovative technology. Dysis has been shown by the NHS Healthcare Technology Appraisal to be the only system which improves Colposcopy accuracy.
