Abstract :
Background: The objectives of this study were to evaluate thyroid lesions, to differentiate between possible benign and
malignant lesions and to assess the diagnostic accuracy of high resolution sonography in thyroid lesions. Methods:
Patients presenting with clinical suspicion of thyroid disease referred to the Department of Radiodiagnosis were included in
the study. Ultrasound was done as an initial diagnostic imaging method and later underwent to ultrasound guided FNAC,
for confirmation of diagnosis. Findings of the thyroid ultrasound scan were correlated with FNAC diagnosis. Results:
Ultrasound was able to pick up lesions in all 100 cases with a sensitivity and specificity of 72 %and 100% respectively.
Ultrasonography showed a Diagnostic accuracy of 97% for thyroid diseases. Sonography could considerably differentiate
between malignant and benign lesions. Ultrasound guided FNAC showed high diagnostic yield for detection of thyroid
diseases. Conclusion: The current study suggests that high resolution sonography can be used as a primary imaging
modality for the evaluation of thyroid diseases with high diagnostic accuracy. Ultrasound helps in guiding FNAC for
confirmation of the diagnosis.
