Before using a diagnostic imaging method, there is usually a clear indication in a doctor's referral, a treatment-relevant, generally valid examination protocol dependent on the indication, or a diagnosis. We have compiled a comprehensive catalogue of indications, which contributes to the targeted and efficient use of our relevant diagnostic method.
