Aim: To explore the use of ultrasonography and Doppler as an indispensable diagnostic modality in the evaluation and the diagnosis of Graves’ disease.
Methods: in this prospective study we examined 30 cases of gravis disease and 20 normal controls using the B- Mode sonographic criteria (thyroid size and echogenicity) and Doppler criteria (color flow mapping and spectral analysis the peak systolic velocity in the thyroidal arteries and the resistive index within the thyroid parenchymal vasculature).
Results: when using more than one sonographic and Doppler criteria, thyroid size, echogenicity, Color flow mapping (qualitative) and spectral Doppler values as peak systolic velocity (PSV) in thyroidal arteries and thyroid parenchyma RI. As a test for diagnosis of Grave's disease. Most patients with Graves’ disease showed increased thyroid volume, heterogeneous parenchyma, marked increased parenchymal vascularity and significantly increased PSV in thyroidal arteries.
Conclusion: Ultrasonography Doppler is a cost-effective, noninvasive, portable, and safe imaging modality in the evaluation of Graves’ disease,
