Of the 97 surgically resected nodules, 67 (69%) were benign and 30 (31%) were malignant. On univariate analysis nuclear atypia ( p < 0.01) was associated with a thyroid malignancy. On multivariable analysis, both ATA high-risk ultrasound features ( p = 0.04, odds ratio [OR] 3.68)...
The amount of blood flow; certain newer ultrasound machines can assess blood flow to the thyroid and its nodules Fine Needle AspirationBiopsy(FNAB) If a thyroid nodule is larger than 1 cm, or it has other worrisome characteristics seen on ultrasound or other imaging tests, then FNAB may be p...

We, thus, compared nodule features in benign and malignant cases. Patients with thyroid cancer were more likely to present with palpable lymph nodes and compressive symptoms. Both ultrasonography and FNAB proved useful in patients with euthyroidism. The first provided an initial characterization of ...
Textural features are obtained from the pyramid at different levels and with different filters. ReliefF method is used for feature selection. Support vector machine is used to classify the thyroid nodule as benign or malignant, and its performance is evaluated using accuracy, sensitivity, specificit...
40. which classified a nodule as ‘suspicious malignant‘ when any of the suspicious US features (markedly hypoechogenicity, microlobulated or irregular margins, microcalcifications, and taller-than-wide shape) were present. In Figs. 1 and 2, two clinical cases were introduced. Figure 1 An ...
15. Marked hypoechogenicity can be a more specific and more reliable criterion for a malignant thyroid nodule than hypoechogenicity in a broader sense with a specificity of 92–94%15,16. A serious concern is that ultrasound echogenicity assessed by clinicians (US-E) has been described ...
Results. There were 68 benign and 2 malignant nodules in a population of 63 female and 7 male patients. The mean benign nodule size was 2.9 cm; 60% were solid; 54% were hypoechoic; 59% were microlobulated or macrolobulated; 47% had central vascularity; 24% contained calcifications; and ...
The largest ultrasound nodule size had a median of 25 mm (IQR 11.5–40 mm) (Table 1). The most commonly affected levels of the neck were IV (76.2%), III (71.4%), IIa (61.9%), and IIb (57.1%) (Fig. 1). The TI-RADS classification was 1 in none of the patients, 2 in four...
To compare the efficiency of four different ultrasound (US) Thyroid Imaging Reporting and Data Systems (TI-RADS) in malignancy risk stratification in surgically resected thyroid nodules (TNs). The study included 547 benign TNs and 464 malignant TNs. US images of the TNs were retrospectively reviewe...
