Overall Ultrasound sensitivity of morphological characteristics is estimated to be 88.8% (24/30) and specificity to be 89.6% (52/55). Negative predictive value is calculated as 94.3% (52/55) and positive predictive value of 80.6 % ( 24/30). CONCLUSION: This study reflects that high ...
Therefore, because thyroid nodule management guidelines are based on the experience prevalently gained in adults,7,10,11 the characteristics in childhood need to be addressed with specific diagnostics. In this study, we presented a large cohort of children and adolescents with thyroid nodules ...
During the diagnostic process, thyroid ultrasound was performed using the Mindray Resona I9 system. A solid, hypoechoic nodule was observed on the left side which was wider than high and had apparent extrathyroid extension and punctate echogenic foci. Additionally, internal vascularity was observed up...
An ultrasound can reveal which thyroid nodules are larger than 1.0 to 1.5 centimeters, requiring further evaluation for cancer. In addition to size, other nodule characteristics that can be noted on a thyroid ultrasound include the following: Number of nodules Location of nodules Distinctness of bord...
In this study, we propose a novel deep-learning-based CAD system, guided by task-specific prior knowledge, for automated nodule detection and classification in ultrasound images. Our proposed CAD system consists of two stages. First, a multi-scale region-based detection network is designed to ...
Three ultrasound nodule characteristics--microcalcifications (odds ratio [OR], 8.1; 95% CI, 3.8-17.3), size greater than 2 cm (OR, 3.6; 95% CI, 1.7-7.6), and an entirely solid composition (OR, 4.0; 95% CI, 1.7-9.2)--were the only findings associated with the risk of thyroid ...
Although important, the clinical evaluation of nodule size, morphology, and function is highly inaccurate. Thus, up to 50% of subjects with a solitary palpable thyroid nodule are found to have multiple nodules when investigated by ultrasound. Additionally, up to 50% of subjects with a normal gla...
Ultrasound-guided fine-needle aspiration cytology was performed in 5 patients, but no abnormal cells were found. Compared to patients without nodules, the age was higher in patients with cysts (54 ± 15 vs. 63 ± 13 years; P < 0.05) and hypoechoic lesions (70 ± 13 years; P < 0.05)....
The presence and characteristics of malignancy detected on follow-up were reviewed. Maximal diameters of each nodule at the initial and last US were measured. Univariate and multivariate analysis were used to assess association with nodule growth 3 mm or larger. Seven malignancies (1.6 %, 7 of ...
Role of ultrasound-guided fine-needle aspiration biopsy in evaluation of nonpalpable thyroid nodules. To determine the role of ultrasound-guided fine-needle aspiration biopsy (US-FNAB) in the evaluation of incidentally diagnosed nonpalpable thyroid nodules ......
