Ein neues echographisches Merkmal zur verläßlichen Differentialdiagnostik des endokrinen Exophthalmus

Abstract

With standardized echography, an ultrasonic method specifically designed for tissue differentiation, Graves' orbitopathy can be diagnosed reliably and accurately even when the clinical picture and thyroid tests are not typical for this condition (e.g., with unilateral exophthalmus, lack of lid signs, euthyroid status). A new echographic criterion of Graves' orbitopathy, i.e., the heterogeneous and high-reflective structure of the diseased muscle tissue, plays a key role in the differential diagnosis.

“…These results imply that the T2 relaxation time is extremely useful in interpreting the activity of Graves' disease and provide a diagnostic tool of prognostic value in monitoring and treating this disease. Die Rontgen-Computertomographie (CT) sowie die Ultraschall-Echographie (US) liefern eine hohe anatomisch-topographische Information Uber orbitale Strukturen (4)(5)(6)(7)(8)(9). Hierbei muf3 mit einem gewissen Informationsverlust durch die eingeschrankte Eindringtiefe des US bzw.…”
