The determination of thyroid gland volume and imaging diagnosis of basedow disease by ultrasound

Background/Introduction: While manual clinical and imaging diagnosis methods expose their shortcomings such as errors, ultrasound becomes an appropriate technique for the measurement of the thyroid volume. \r\n', u'Objectives: We determine the thyroid in patient with Basedow disease by ultrasonography before radioiodine, diameter, measurement of thyroid volume, and the lesion echogenicity.\r\n', u'Subjects and method: The study groups consist of 264 patients, in which there are 53 men (20.07%) and 211 women (79.92%), in Bach Mai Hospital. The youngest is 16 years old and the oldest is 73. With a medium age of (42.97 \uf0b1 12.06) years (range from 16 to 73). The most common group ranging from 40 to 50 years of age, equivalent to a number of 80 patients (30.30%). Surveyed participants include 1845 people with normal thyroid. All of them underwent ultrasound scans with a 7.5 MHZ transducer. This is a prospective study. \r\n', u'Results/Outcomes: The average volume of thyroid is (37.03 \uf0b1 19.77) ml compared to the group with approximate thyroid volumes (p > 0.05 based on the ANOVA). Basedow patients\u2019 thyroid volumes tends to be bigger at the adult age, and were bigger than those of normal people (p = 0.0001 t test). 138 (52.27%) surveyed patients had diffuse injuries. 126 patients (47.73%) have thyroid glands which contained multiple nodules. 197 (96.57%) of them had nodules that were \r\n', u'solid echodense and echomix, and 35 (16.36%) had calcifications.\r\n', u'Conclusion: Ultrasonography (US) has become an important asset in thedetermination of thyroid volume at referred for 131I treatment and the evaluation of thyroid nodules of patients with Basedows\u2019 disease associated with nodules. These data suggest the value of surgery in Basedows\u2019 disease associated with nodules, to eliminate the risk of malignancy.\r\n', u'

Determinining the thrydoid volume of healthy aldult by Multi slice computer tomographyin comparision to ultrasound

Background: Currently there is a few research on thyroid volume determined by computer tomography scanner (CT-scanner)\r\n', u'Objectives: to add and to develop normal thyroid indicators by CT scanner method.\r\n', u'Subjects and method: Researchers determined thyroid volume in 45 normal persons (27 males, 18 females) in Bach Mai Hospital by Multi slice computer tomography (MSCT). The control ultrasound group has 1845 persons (living in Hanoi and Khanh Hoa. All of them were clinically tested with normal thyroid.\r\n', u'Results: The result of measurement by ultrasound and MSCT in the comparison (both two genders) as follow: \r\n', u'The width of the right and left lobe of thyroid measured by ultrasound were bigger than those measured by MSCT (p<0.05 as T-test). The depth of the right and the left lobe of thyroid measured by ultrasound were smaller than those measured by MSCT (p<0.05 as T-test). The length of the right and left lobe of thyroid measured by both methods gave nearly the same result (p>0.05 as T-test). In three formulas measuring thyroid volume according to ellipse, the V3=0.479 a.b.c formula shows the results which nearly same as those by MSCT directly.\r\n', u'Conclusion: Thyroid volume measured by MSCT in this study is smaller than the result of some foreign studies (p <0.05).\r\n', u'\r\n', u'\r\n', u'

Study on the thyroid of healthy adult people by computer tomography

The authors determined the length, width and depth of thyroid lobe and thyroid volume by computer tomography (CT). Results: there was no statistically significant difference in the width of right lobe with that that of left one (p>0.05), but the length and depth of right lobe is higher than those of left one (p0.05), but in general the volume of right lobe is higher than that of left one.

Assessing the change of ultrasonic image and the thyroid volume in Basedow patients

The thyroid volume and ultrasonic image of 356 healthy adults and 133 Basedow patients were assessed. The results are as follow: Thyroid gland of Basedow patients has low, diffusive echo and no steady border... These volumes are bigger than that of healthy adults (39.18ml+/-19.02ml, n=133 vs 12.06+/-4.07, n=356), p<0.0001.
