Abstract:
Thyroid scintigraphy using Tc-99m pertechnetate is a frequently performed procedure in routine nuclear medicine practice. There is no clear description of thyroid diseases pattern in Sudan using nuclear medicine as a diagnostic tool. The aim of this retrospective study was to classify the pattern of thyroid nodules using the nuclear medicine facilities in National Cancer Institute during a period (2014-2015).
All patients referred to the department of nuclear medicine for thyroid scan from January 2014 to December 2015 were included in this study .Data were analyzed by SPSS software. A total of 1538 subjects were included in this study (142 male, 1396 female with ratio of 1:9, mean age 38.4 ±15.08 years). All subjects underwent static thyroid scintigraphy after injection of 99mTc-O4, thyroid uptake and scan were taken as a conclusion of the thyroid report; the thyroid nodules were classified, in addition to other thyroid diseases. The total numbers of thyroid nodules were compared with other thyroid disease. The percentages of each type were calculated and comparison of all types was determined. The percentage of cold nodule was (2%) , hot or toxic nodules was (19%) , simple multi nodular was (31%) and toxic multinodular was (4%) in a total of nodular goiter (56 %). This study concluded that, there was high percentage of nodular goiter among the patients under study.
