Thyroid lesions in ultrasound diagnosis and clinical diagnosis


50 cases of nodular goiter, 50 cases of methylene inflammation in 32 cases, thyroid cancer, 22 cases of chronic lymphocytic thyroiditis l0 cases. 1.2 Instruments used AcusonSequoia512 color ultrasound, use broadband probe, the probe frequency range of 5 ~ 12MHz. 1.3 Detection methods were supine,ralph lauren paris, neck pillow, was hyperextended, fully exposed to the neck, the application of direct method of thyroid scanning multi-faceted area, regular observation of thyroid morphology, size, internal echo and color flow signals, etc., If you find lumps, to its location, size, shape, internal echo, borders, with or without halo, such as calcification and posterior wall echoes were observed. Then use the color flow to the tumor blood flow distribution within and around to observe, measure its spectrum. If the tumor is located in the edge of the thyroid, can Zhu Huanzhe swallow, to identify whether the thyroid tumor related. 1.4 Section 264 cases of thyroid lesions ipsilateral thyroid test results show varying degrees of enlargement, ultrasound diagnosis and pathologic diagnosis of the total coincidence rate was 84.9% (40/264), thyroid adenoma diagnosis rate of 90135 / 150), nodular goiter 80.0% (40/50), methylene inflammation 90.6% (29/32), I slowly Health lymphocytic thyroiditis 60.0% (6 / 10), thyroid cancer 63.4% (14/22). 2 Discussion 2.1 thyroid adenoma were round or oval, coating finishing, the boundary is smooth, clean, visible halo surrounding the tumor surrounding normal thyroid tissue, the internal echo much more uniform, when combined cystic degeneration, hemorrhage , calcification, can occur within the tumor area and a strong echo echo-free group, the tumor is slightly enhanced posterior echo, usually silent decay, some visible lateral acoustic shadow. CDFI: a clear surround around the tumor blood vessels,nike free run, blood flow within the rich or not rich, exploration and arterial blood flow spectrum. Author: Henan Military Region directly under the out-patient department (Zhengzhou 450003) Author: Ren Xinchun, female, 38 years old, head technician. 67 · 2.2 methylene exchange of experience inflammation of thyroid parenchyma shows hypoechoic areas,moncler jakke dame, irregular, blurred boundaries, without the surrounding The vascular lesions seen in normal thyroid walk through, observe the lesion is usually located in the dynamic side of the thyroid lobe, involving the other side of the long leaves, 3 to 6 months after the lesions gradually reduced or even completely back to normal, the disease often occurs in the upper respiratory tract infection or almond pancreatitis after a history of fever and throat. 2.3 nodular goiter usually occurs in the bilateral glands, and multiple, fuzzy boundaries, incomplete capsule, irregular shape, size, echo level varies between the fibrous tissue nodules scattered in separate display shape, irregular-shaped linear echo. CDFI: the majority of nodules was seen around the surround blood vessels, blood supply within the rich, part of a larger mass within the fluid flow when no signal display. 2.4 malignant thyroid cancer papillary carcinoma in the most large and overlapping cells, stromal components less, ultrasound images in real hypoechoic common. The lower cell differentiation, nuclear shaped the greater the tumor stroma, the less the better sound transmission,moncler doudoune, the lower the echo. Ultrasound of the pathological type of thyroid has been difficult. Sonographic features of thyroid cancer, irregular shape, irregular borders, and some were Crab-like invasion to the surrounding normal tissue and tumor parenchyma visible microcalcifications. Thyroid cancer is not all lumps are equipped with the typical ultrasonographic signs, there are not typical, such as well-differentiated follicular carcinoma can be expressed as a clear boundary, neat, similar to the sonographic thyroid adenoma, thyroid cancer due to some hemorrhage, necrosis or cystic degeneration and echo-free zone, or cyst-like sonography, and benign tumors more difficult to identify. Cervical lymph node enlargement can be identified as a thyroid benign and malignant tumors of a method should also be with CT, isotope scanning combine, if necessary, tumor puncture cytology in diagnosis. Through the examination of 264 patients analyzed, appreciate high-frequency ultrasound for the diagnosis of thyroid cancer sensitivity is high, less than 0.5cm nodules can be detected, the early detection of cancer has an important value. But the fact that two-dimensional images and color Doppler signals on the nature of some thyroid cancer is difficult to determine, therefore, need imaging and clinical manifestations and laboratory examinations other closely,moncler jacken, in order to improve diagnostic accuracy.
