Measurement Of Thyroid Isthmus Thickness InYounger Sudanese Adults Using Ultrasonography

Abstract

Background :Thisdescriptive study deals with the ultrasound finding of thyroid isthmus thickness. The problem of study is there is no reference value in adult Sudanese ,the isthmus thickness may increase or decrease different pathological condition The objective of study was to measurement the thyroid isthmus thickness in younger adult Sudanese in different ages (from 18-30 years)using ultrasonography and detectingif there is relationship between the isthmus thickness and volume of thyroid. it was carried in 51person (11 male and 40 female) in Aljazeera state.The study was conducted during the period extended from December 2018 to August2019 . The machine used in the study were Dp -1100 mindary with 8-10 frMhz , linear probe was used by a dedicated single operator.all volunteers with supine position technique. the data was collected in sheet designed which include age, isthmus thickness, length of right lobe, width of right lobe, depth of right lobe, length of left lobe,width of left lobe, depth of left lobethe data was analyzed by using (SPSS software program version 20) . In results show the normal values of isthmus thickness were determined according to age groups and show the minimum 2.4,maximum 5.3mean 3.4 and stander deviation is 0.6 in 51 person. In conclusion show there is correlation between isthmus thickness and total thyroid volume with age (P*value 0.05)and there is significant correlation between isthmus thickness with age(P*value 0.05).it increasing by 0.039with increasing the age in any five years starting from 2.7mm. V The researcher recommended to take large sample and using other parameters like body surface area ,body mass index , height and weight of the body and comparing between the two gender.
