Bildgebung peripherer Nerven (Sonografie; MRT): Vorschlag für eine Systematik zu Indikationen für die klinische Praxis an FallbeispielenImaging of Peripheral Nerves (sonography; MRI): Proposal for a System of Indications for Use in Clinical Practice – a Case Study
For investigating peripheral nerves, there are technically well established imaging methods (sonography, MRI). In clinical practice, in every single case, a decision has to be made as to the necessity for diagnostic nerve imaging. We propose a system for decision-making and illustrate it with selected cases. A prerequisite is an electrophysiological diagnosis, neuro-/myography, with evidence of peripheral nerve lesion. Additionally, if one of the following questions is answered positively, an indication for an imaging study is given:
Is the localization of nerve damage unclear after electrodiagnostic tests?
Is a typical nerve compression syndrome absent?
Is there traumatic or postoperative nerve damage?
Does symptom amelioration fail to occur within the expected timeframe?
