Thyroid gland volume in infants, children and adults from Sharkia governorate: Ultrasonographic study

Thyroid ultrasonography has proven a useful and practical method for the assessment of thyroid size.Thyroid ultrasonography were carried out first to determine the standard thyroid volume in normal children and adolescents.Second to establish a standard growth curve of thyroid volume with respect to age, sex, height and weight. We effected sonographic examination of 220 patients [110 females and 110 males] from Sharkia governorate aged between 1 day and 18 years and body weight from 2.0 kg to 90.0 kg. In this study the volume of thyroid glands in newborn is 0.8 ml +/- 0.21 ml. Mean thyroid volume was found 5.5 ml +/- 0.61 ml in 6-8 years old, while it was 17.5 ml +/- 2.35 ml in 14-16 years old male and 15.3 ml +/- 2.51 in 14-16 years old female. The right lobe was larger than the left one in all age groups. Thyroid volume determined by ultrasound in control children increased with age up and was correlated with height and body weight

Evalation of deep venous thrombosis in the lower limbs and pelvis. mr venography versus duplex doppler sonography

This study was designed to show the comparable diagnostic value of MR venography and color Doppler Sonography in the assessment of deep venous thrombosis [DVT]. Twenty five patients with clinically suspected DVT of the lower limb and pelvis were included in this study. Two Dimensional Time of Flight MR venography and color Doppler sonography were performed to all cases twelve hours before conventional venography. The data were collected prospectively and analyzed in blinded manner. In evaluating DVT in the pelvic region, MR venography was superior to color Doppler sonography, reported 91% sensitivity and 99.4% specificity versus 78% sensitivity and 98% specificity for Doppler sonography. MR venography and color Doppler sonography were 100% sensitive and 100% specific in evaluating DVT in the thigh region. While, MR venography surpassed both techniques in evaluating DVT in the calf veins, with sensitivity and specificity of 87.5% and 99% respectively versus 67% sensitivity and 97% specificity for color Doppler sonography. MR showed more ability to assess the extent of thrombus. MR venography showed 47 collateral vessels, where as only 40 were dedected by contrast enhanced venography. The combined readings of axial and maximum intensity projection MR images was significantly modified the levels of sensitivity and specificity of MR venography. MR venography was more sensitive than color Doppler sonography in evaluating pelvic and calf DVT. Where as both techniques were equivalent in evaluating femoro popliteal DVT. MR venography showed better demonestration of thrombus extension and collaterals
