The value of color Doppler imaging in the diagnosis of thyroid masses
Dr. Iman Khaleel
The u /s examination was used early as 1955 to outline the thyroid gland abnormality, size of the gland, its consistency, if there is any nodular abnormality and its nature (solid or cystic) and to detect the occult malignancy and its recurrence. In our study the u/s with color Doppler technique is used in (94) patients with different thyroid lesions during the period of (12) months, pathological proof were obtained in (80) cases. According to our CD study the patterns of vascularity of the lesions are classified into four types, where it shows 87.5%, 94%, 63.6%, 98.6% sensitivity, specificity, PPV and NPV, respectively, for detection of malignancy. So it has been found that the conventional u/s in conjunction with CDI is considered as useful primary investigation tool in diffrential diagnosis of thyroid masses, being non invasive, simple, safe and time saving.
