Objective:
The objective was to correlate the number, size and extent of the nodules as determined during the preoperative clinical examination of the thyroid gland, USG, intra-operative examination and histopathology. Also, FNAC (with or without USG guidance) and USG findings suggestive of malignancy were correlated with the final histopathology.
Setting:
Tertiary referral centre
Patients:
A retrospective chart review was done for 106 patients who underwent surgery for benign or malignant nodular thyroid disease in our center, between Jan 2004-Dec 2006.
Results:
USG has 7 times higher predictive value than clinical examination in detecting number of nodules and determining size of nodules. USG guided FNAC has a sensitivity of 85.71% and specificity of 90.0% in detecting malignancy in nodular thyroid disease. However for predicting malignancy in thryoid nodules, this study shows that USG has a sensitivity of 20.0% and specificity of 97.67%.
Conclusion:
In patients with nodular thyroid disease, USG can accurately determine the number and the size of the nodules. It is extremely useful in guiding FNAC; However its role in predicting malignancy is doubtful. We therefore recommend that USG guided FNAC be carried out as a routine in the evaluation of thyroid nodules.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
