Background: AmCAD is a window-based computer-aided detection (CAD) device intended to assist the medical professionals for categorization of thyroid nodules through ultrasound. CAD is an objective way to determine which thyroid nodules need to have fine needle aspiration cytology (FNAC) and helping to reduce FNAC frequency in the thyroid. It saves workload, and there is no interobserver variation. Nodular thyroid disease is very frequent in clinical practice in Pakistan and worldwide. It is associated with increased risk of thyroid cancer and hyperfunction. In this paper, we propose a novel method for CAD of thyroid nodules in ultrasound (US) images followed by treatment if possible by Radiofrequency ablation (RFA). This novel method was experimentally evaluated using US images acquired from 24 patients. The results show that the proposed method achieves more accurate delineation of the thyroid nodules in the US images and faster convergence than other relevant methods. Methods: The purpose of this article is to introduce application and utilization of the CAD system in thyroid ultrasonography. After getting clear images of thyroid nodule along with longitudinal and traverse measurements, four parameters are calculated and displayed by the computer system automatically, which include microcalcifications, hypoechoic lesion, heterogeneity, and indistinct margin. Results: The results are displayed automatically with pointers in the semilunar figures. The necessity of FNAC dependents on the size and numbers of positive findings along with percentage risk of malignancy. Conclusion: This CAD system is objective, reproducible, and easy to use. It can be easy to determine the necessity for FNAC, but what we must keep in mind is that this method can reduce the necessity of FNAC, not replace FNAC for the diagnosis of thyroid cancer. RFA of thyroid nodule is minimally invasive very good tool as mode of treatment.
