This can lead to delayed diagnosis, which is crucial for timely initiation of therapy and, consequently, for a better prognosis. Long-term therapy management is also challenging, as objective parameters for assessing therapeutic success are largely lacking.\n\nMSOT can detect inflammation through the measurement of hemoglobin, a method that our research group has already successfully demonstrated in patients with chronic inflammatory bowel diseases (Knieling, NEJM 2017). The use of MSOT could therefore also be applied to nerve inflammation, allowing for earlier detection of inflammation and nerve damage and contributing to timely treatment of patients.\n\nFor nerve imaging, a CE-certified MSOT device from iThera Medical is available at the Pediatric Clinic in Erlangen. In addition, a non-CE-certified device with lower laser power is available, which can be used for bedside examinations.\n\nThe arm nerves will be examined in three cohorts, which will be compared with each other and with standard diagnostics (blood tests, electrophysiology, conventional ultrasound).\n\nEach cohort will include ten healthy control subjects, ten patients with CIDP, and ten patients with GBS.",[44,45],"CIDP - Chronic Inflammatory Demyelinating Polyneuropathy","Guillain-Barré Syndrome (GBS)",[47,48,49],"MSOT","PAI","Nerve Ultrasound","NOT_YET_RECRUITING","2025-08-06",{"date":53,"type":54},"2025-08-14","ACTUAL",{"date":51,"type":40},{"date":57,"type":40},"2027-08-06",{"name":5,"class":6}]
