Purpose: To evaluate computed tomography (CT) detection of solitary thyroid calcification for identifying thyroid papillary carcinoma and to determine whether the predictive ability changes when the size increases after enhancement.
Materials and methods: CT scans on all 96 patients with thyroid nodules who underwent both enhanced CT examination of neck and thyroidectomy from 2014 to 2016 in the Shandong Cancer Hospital affiliated to Shandong University were reviewed. Us futures markets The cases without calcification and the cases with peripheral calcification, multiple coarse calcifications, or punctate calcification were excluded. Sprint
troubleshooting Imaging features, including location and size of the lesions, were reviewed on plain and contrast-enhanced CT. Futures and options trading meaning The patients were grouped by histological results. Us to cad calculator The comparisons were evaluated by using Fisher’s exact test and binary logistic regression.
Results: The study population consisted of 96 patients (74 females, 22 males; mean age 49.8±11.3 years). Python tutorial download Papillary thyroid carcinoma was observed in both solitary calcified thyroid nodules (85.4%) and solely coarse calcifications surrounded by low-density focus (58.2%). Msn news headlines The difference was significant ( P=0.006). Binary code translator to english Of 64 patients with an amplification of lesions after contrast enhancement, 58 (90.6%) were diagnosed with a malignant lesion. Silver price forecast 2020 At the same time, of the 32 patients with no increase in size, 10 (31.2%) were diagnosed with carcinoma and 22 (68.8%) with nodular goiter. Eur usd historical data download This difference was significant ( P<0.001), and after binary logistic regression, increasing size was an independent risk factor for cancer.
Conclusion: Solitary calcified thyroid nodules detected on CT represent a high risk for papillary thyroid carcinoma, especially when the size of the lesions increases after contrast-enhanced CT.
