Comparison Of Doppler Indices With FNAC Findings Among Patients With Thyroiditis

Abstract

The superior thyroid artery Doppler study offers additional advantages by characterizing vascular flow changes specific to thyroiditis. Increased vascularity, as evidenced by elevated PSV or altered RI and PI values, is a hallmark of inflammatory thyroid diseases, such as Hashimoto's or De Quervain's thyroiditis. Correlating these Doppler findings with biochemical and cytological parameters enables precise differentiation, fostering early diagnosis and optimal management. The study was conducted at the Department of Radio-Diagnosis. This setting was selected due to its accessibility to a large and diverse patient population, including both outpatient and inpatient referrals for USG of thyroid. The institution is equipped with state-of-the-art diagnostic facilities, including high-resolution ultrasound (HRUS), essential for this study. The medical sciences institute provided a well-controlled environment for imaging and clinical examinations, making it an ideal location for collecting accurate and reliable data. In this study the mean PSV in Graves’ disease was 74.60 ± 3.30 cm/s, while in Hashimoto’s thyroiditis the mean PSV was 25.54 ± 2.84 cm/s, and in subacute thyroiditis the mean PSV was 50.32 ± 2.96 cm/s. In this study the mean PI in Graves’ disease was 1.50 ± 0.05, while in Hashimoto’s thyroiditis the mean PI was 0.91 ± 0.04, and in subacute thyroiditis the mean PI was 1.17 ± 0.05.
