The mean follow-up period was 20.4 months (range 6 months-5 years). As a result, 19 patients were ablated with a single dose of I-131 (2-4 GBq). A total of 6 patients took a second dose of radioiodine treatment for lymph node or distant metastases. One of these

patients was 6 years old and had recently received ablation. He had diffuse lung metastasis, which was detected on the 6th day post ablation with whole body scintigraphy, and he is now under follow-up. Successful surgery and an effective radioiodine ablation have a crucial role in good outcomes of childhood DTCs.”
“Purpose: To investigate factors influencing the quality of ultrasonographic (US) elastography in FRAX597 solubility dmso the evaluation of suspicious breast masses.

Materials and Methods: This prospective study was conducted with institutional review board approval; written informed consent was obtained. Between January 2009 and February 2009, real-time US elastography of 312 breast masses (245 benign, 67 malignant) was performed in 268 consecutive patients (mean age, 45.7 years +/- 10.2 [standard deviation]) prior to US-guided core biopsy. Five breast radiologists who had performed the examinations assessed the quality of elasticity images as inadequate, low, or high without histologic information. Age, body mass index

(BMI), mammographic density, lesion size, lesion depth, and breast thickness at US were analyzed for their association with image quality by using the chi(2) test, Student t test, and multivariate analysis. Sensitivities and specificities for the differentiation of benign from malignant masses on the basis of elastography were calculated and compared between groups of quality scores by using the logistic buy 3-MA regression method.

Results: The quality of elasticity images was assessed as inadequate in 21 (6.7%) cases, low in 134 (42.9%), and high in 157 (50.3%). According to univariate analysis, smaller lesion size (P = .001), shallower lesion depth (P = .005), less breast thickness

where the lesion was located (P < .0001), and benign pathologic finding (P = .004) were significantly associated with higher image quality. There was no correlation of image quality with age (P = .213), BMI (P = .191), mammographic density (P = .091), or distance from the nipple (P = .100). Multivariable analysis showed that breast thickness at the location of target lesions was the most important factor influencing elasticity image quality (P = .001). There were significant differences in sensitivity between higher-quality and lower-quality images (87.0% vs 56.8%, respectively; P = .015) in the differentiation of benign from malignant masses.

Conclusion: Breast thickness at the location of the lesion was the most important factor influencing image quality at US elastography.
