Introduction: Thyroid disease is a common medical disorder. And thyroid cancer considered the second-most common cancer among the young Saudi females. Ultrasonography (US) and computed tomography (CT) are used in the diagnosis of thyroid nodules. However, US has its limitations, and CT scan is superior in detecting important details that would affect patient care and prevents possible complications. Objective: The study evaluates the benefits of CT scans implementation together with the US as a preoperative evaluation of any thyroid diseases which can improve thyroid patient care. Methodology: The retrospective study was conducted on a total of 207 patients, in a tertiary center, Riyadh, Saudi Arabia. Results: A total of 207 patients with thyroid diseases who had both US and CT scan done despite thyroid surgery done or not (164 females and 43 males; mean age, 44.6 ± 14.5 years) were included in our study, and any patient with improper imaging protocol or poor US or CT image quality was excluded. From there, 207 patients, we had 88 patients with benign and 85 with malignant pathology (+34 patients no surgery done for them). The present study showed that US had better specificity and accuracy in the prediction of thyroid malignancy comparing to the CT scan. Furthermore, CT had a significant P < 0.05 in detecting extension to retrosternal or surrounding structures, major vessels involvement, tracheal compression, and pathological lymph node. Conclusions: CT scan of the neck is a useful technique in detecting additional details about the thyroid and surrounded tissues. This study suggests that preoperative CT scan implementations on top of US are positively associated with a good strategy of surgery, postoperative complication prevention, and to success the thyroid surgery in the Saudi population.
