As with guidelines from professional groups such as the American Thyroid Association and the Korean Society of Thyroid Radiology, the threshold size for recommending FNA decreases as the US features become more malignant appearing (3,4). Because the threshold diameters for mildly and moderately suspicious nodules (TR3 and TR4) are larger than. ACR TI-RADS is a reporting system for thyroid nodules on ultrasound proposed by the American College of Radiology (ACR) 1.. This uses a standardized scoring system for reports providing users with recommendations for when to use fine needle aspiration (FNA) or ultrasound follow-up of suspicious nodules, and when to safely leave alone nodules that are benign/not suspicious Following ACR TIRADS management guidelines would likely result in approximately one-half of the TR3 and TR4 patients getting FNAs ((0.5 × 37) + (0.3 × 23) = 25, of total 60), finding up to 1 cancer, and result in 4 diagnostic hemithyroidectomies for benign nodules (25 × 0.2 × 0.8 = 4) Results: The score in all benign (TI-RADS 2) or probably benign (TI-RADS 3) thyroid nodules was zero. In the TI-RADS 3 group only 2.2% of the TNs were malignant. The scores of TI-RADS 4a, 4b and 4c were one, two and three to four points, respectively. The malignancy rates were 9.5%, 48% and 85%, respectively. TI-RADS 5 TN had a score of five or more points with a malignancy of 100% in this study

Results: Whereas 15.9% of the nodules were classified as TIRADS 3 or lower and less than 0.1% as TIRADS 5, most of the nodules were classified as TIRADS 4A (29.3%), 4B (29.3%), or 4C (24.9%). Altogether, more than 80% of the autonomous thyroid nodules were classified as TIRADS 4A or higher, a grade that would result in a recommendation of fine. Numerous sets of guidelines have been proposed regarding ultrasound of thyroid nodules. None has been universally accepted. American College of Radiology-Thyroid Imaging, Reporting and Data System (ACR-TIRADS) has been promoted as an improvement to existing guidelines such as the 2015 revised Americ Lobulated or irregular 2 points.

The overall objective is to improve outcomes for patients. The specific aims are to The odds ratio (OR) was 7 for TIRADS 5, 2 for TIRADS 4B, 0.67 for TIRADS 4A, 0.2 for TIRADS 3 and 0.01 for TIRADS 1 & 2. The PPV of malignancy rises gradually from 0% for TIRADS 1 & 2 to 6.7% for TIRADS 3 & 4A to 20% for TIRADS 4B and reaches 67% for TIRADS 5. TIRADS 5 showed 100% sensitivity, 86% specificity and 89% accuracy The percentages of malignancy is defined in our TIRADS were as follows: TIRADS 2 (0% malignancy), TIRADS 3 (3.6% malignancy), TIRADS 4 (17-75% malignancy), and TIRADS 5 (98% malignancy). We established a novel TIRADS to predict the malignancy risk of the thyroid nodules based on six categories US features by a scoring system, which included a. In ACR 3-4-5, a correspondence with the follow-up occurred in 60.3%, 50.2% and 51.9% of cases. The ACR-TIRADS is a useful risk stratification tool for thyroid nodules, although the current dimensional thresholds could lead to an underestimation of malignant lesions

The expert panel analyzed the current versions of TIRADS risk stratification and non-TIRADS risk stratification (e.g., ATA and AACE/ACE/AME guidelines [2, 20]) and agreed with many studies that there is no absolute perfect risk stratification system and that each one has specific strengths and limitations [21,22,23,24,25,26,27,28,29] Thyroid Imaging Reporting and Data System (TI-RADS) Thyroid nodules are extremely common with a reported prevalence ranging between 8.2% and 64.6% in autopsies and 19% to 68% in adults on high-resolution ultrasound. Most of the time, thyroid nodules are detected accidentally when neck imaging is done for some other reasons malignant ( 2,3 ). Although many reports have demonstrated malignant US fea-tures that necessitate US-guided fi ne-needle aspiration biopsy (FNAB) ( 2,4- 11 ), it is still diffi cult to decide which lesions should undergo FNAB because the same thyroid nodule may be clas-sifi ed in different ways with different guidelines ( 2,4-8 ) 3.2 Agreement between ultrasound risk stratification systems.

ATA TIRADS had the highest specificity and PPV (SPEC: 67.3%, PPV: 65.4%). BTA TIRADS yielded the lowest sensitivity and NPV (SEN: 66.3%, NPV: 66.3%) while ACR TIRADS has the lowest PPV (56.1%). The six TIRADS generally had similar diagnostic performance and discrimination of benign and thyroid nodules as illustrated by the ROC curve . ACR, ATA. When the biopsy size threshold increased from 1 to 1.5 cm for K-TIRADS 4 nodules and from 1.5 to 2 cm for K-TIRADS 3 nodules, there was a more substantial decrease (27.0-28.9%) in the unnecessary biopsy rate of benign nodules and a further decrease (15.0-27.1%) in the sensitivity (66.4-80.7%) for detecting malignant tumors [10, 11] size threshold for biopsy was subdivided into 1 cm for K-TIRADS 4B and 1.5 cm for K-TIRADS 4A, and the size threshold for biopsy was raised from 1.5 cm to 2 cm for low suspicion (K-TIRADS 3) nodules. Assessment of the Diagnostic Performance of Risk Stratification Systems for Thyroid Malignanc The concordance rates were 49.7%, 41.0%, and 42.3% between European TIRADS and ACR TIRADS category 5, 4, and 3 nodules. When Korean TIRADS and European TIRADS were compared (Table S1), substantial discordance (> 5% of all nodules) was found in 53.7% and 40.1% of Korean TIRADS 4 and 3 nodules, which were categorized as European TIRADS 5 and 4. Each included nodule was classified by one radiologist blinded to the cytological and histological diagnoses according to the ACR TIRADS scores and the US patterns as recommended in the 2015 ATA guidelines. The risk of malignancy was estimated for Bethesda, TI-RADS scores, ATA US patterns and their combination

Thyroid Volume 26, Number 1, 2016 Classification ATA European Thyroid Association Guidelines for Ultrasound Malignancy Risk Stratification of Thyroid Nodules in Adults: The EU-TIRADS. Eur Thyroid J 2017;6:225-23 The TIRADS by the European Thyroid Association, namely EU-TIRADS, was the last one to be published. Design: We conducted a meta-analysis to assess the prevalence of malignancy in each EU-TIRADS class and the performance of EU-TIRADS class 5 vs 2, 3 and 4 in detecting malignant lesions The malignant rate by observer-consensus was 25% for TIRADS 1-3, 21.2% for TIRADS 4, and 50% TIRADS 5 . The diagnostic values of the ATA/TIRADS determined by CAD and observers are shown in Table 5. The CAD software appeared to have higher average accuracies than the observers (0.675/0.68 and 0.64/0.655, respectively) For this purpose, we reanalyzed the ratio of unnecessary biopsy for the EU-TIRADS system when the size thresholds of EU-TIRADS were hypothetically changed to the values equaling the size criteria of the ACR-TIRADS system (i.e., FN AB, if the nod ula r length is [greater than or equal to]2.5 cm for EU-TIRADS 3, [greater than or equal to]1.5 cm. The goal of the second iteration of TIRADS , a system developed in Korea by Kwak et al. in 2011, was to develop a practical and less complex TIRADS stratifying malignancy risk and focused on FNA decision-making [] (Table 14.1).These authors stressed that in parallel to BIRADS, differentiating category 3 from 4 was crucial because surveillance is recommended for the former and biopsy for.

Using cutoff for EU-TIRADS 5, 93.4%, 54.6%, respectively. Conclusion: The application of EU-TIRADS guidelines allowed us to achieve moderate specificity. The vast majority of malignancies in EU-TIRADS 3, 4, and 5 would not have been recommended for biopsy because having a smaller size than that proposed classification In one study, a direct comparison was made between the TIRADS and the ATA guidelines . Yoon et al. reported that TIRADS was superior to the ATA guidelines in terms of sensitivity (97.4% vs 95.3%; p<0.001), although the ATA guidelines were superior to TIRADS in terms of specificity (37.4% vs 29.3%; p<0.001) and PPV (98.1% vs 23.3%; p<0.001) When a TN has a B-III cytology, with a TIRADS 2, 3. and 4a US report (estimated malignancy risk of 0-10%), a repeat FNA at six to 12 weeks may cause changes due to external factors, leading to degenerative processes in the TN through a hemorrhage, granulation tissue, fibrosis, and sclerosis The aim of this study was to compare the diagnostic effectiveness of EU-TIRADS in two groups of nodules with equivocal cytology (categories III-V of Bethesda system), with and without Hürthle cells (HC and non-HC). The study included 162 HC and 378 non-HC nodules with determined histopathological diagnosis (17.9% and 15.6% cancers). In both groups calculated and expected risk of malignancy. Compared to TIRADS, the 2015 ATA guidelines yielded a significant higher specificity (79.6% vs 71.5%, P = 0.04), while TIRADS had a higher sensitivity (83.2% vs 77.3%, P = 0.02)

TIRADS classification varied between the three observers. Thyroid nodules were classified as TIRADS-2 in 12-45 cases, TIRADS-3 in 0-3 cases, TIRADS-4 in 33-84 cases and TIRADS-5 in 18-33 cases. Details and association of scoring from each observer with the risk of malignancy are shown in Table 2. Correlations using the Spearman. The risk of malignancy is in TIRADS 5 is put at 81%, therefore, TIRADS is a sensitive classification in recognizing patients with thyroid cancer and can be used as a guide in deciding the need for fine needle aspiration biopsy.

TIRADS Reporting guidelines for thyroid nodules: Nodules should be measured in three orthogonal planes. If there are multiple nodules, TIRADS 3 nodule is a thyroid nodule that is mildly suspicious based on ultrasound findings. The score for this nodule is 3 points Results: The score in all benign (TI-RADS 2) or probably benign (TI-RADS 3) thyroid nodules was zero. In the TI-RADS 3 group only 2.2% of the TNs were malignant. The scores of TI-RADS 4a, 4b and 4c were one, two and three to four points, respectively. The malignancy rates were 9.5%, 48% and 85%, respectively.
