Objective: To investigate the diagnostic value of color Doppler ultrasonography in detecting calcifications in thyroid nodules for benign and malignant thyroid nodules. Methods: This study selects 108 patients with thyroid nodules who underwent color Doppler ultrasonography at designated hospitals from June 2013 to June 2018 as study subjects, retrospectively analyzes their general patient data, preoperative color Doppler ultrasound data and postoperative pathological diagnosis results, and discusses the diagnostic value of calcification rate, calcification type and calcification characteristics for benign and malignant thyroid nodules. Results: The results show that preoperative color Doppler ultrasonography found 112 thyroid nodules in 108 patients, including 72 benign nodules and 40 malignant nodules; pathological analysis confirmed 124 thyroid nodules, including 78 benign nodules and 46 malignant nodules; the diagnostic coincidence rate of color Doppler ultrasound is 90.32% (112/124), the misdiagnosis rate is 9.68% (12/124), the specificity is 86.94%, and the sensitivity is 81.27%; in these 112 thyroid nodules, 89 nodules were calcified accounting for 79.46%; in 72 benign nodules, 13 nodules were calcified accounting for 18.06%; in 40 malignant nodules, 17 were calcified accounting for 42.50%; the calcification of malignant nodules was significantly higher than that of benign nodules; in 72 benign nodules, 6 cases is coarse calcification accounting for 8.33%, 3 cases is cyclic calcification accounting for 4.16%, and cyclic and coarse calcification are only 23.46% sensitive to thyroid cancer; in 40 malignant nodules, 3 cases is coarse calcification accounting for 7.5%, and 2 cases is cyclic calcification accounting for 5.00%. Conclusions: According to the analysis, the calcification in thyroid nodules has relatively high sensitivity and specificity for the diagnosis of benign and malignant nodules and it can be used as a specific index for screening thyroid cancer.

Significant Difference

Method: A sample size of 40 kidney allograft recipients undergoing color Doppler Ultrasonography evaluation included in the study. Result: Corticomeduallry differentiation of kidney allografts within 24 hours post transplant period: There was no significant difference between CMD of kidney allorgrafts with complication and kidney allografts without any complication within 24 hour because the standard deviations of both groups were 0. Corticomeduallry differentiation in all kidney allografts, all were shows maintained corticomedullary differentiation. Conclusion: This study is aimed to assessing the role of CDUS in kidney allograft recipients to evaluate the graft perfusion immediate after anastamosis, within 24 hours and follow up period after engraftment of kidney allograft. Analyse the Color Doppler Ultrasound (CDUS) indices changes in parenchymal, and vascular cause of allograft dysfunction at follow up periods, to evaluate the uroloical, surgical and vascular complications in kidney recipients by using gray scale and color Doppler US at follow up periods and compare the results with biochemical parameter (serum creatinine). Immediate Doppler ultrasound is highly useful in the diagnosis of primary graft dysfunction and in follow-up of the transplanted patient.

Carotid Artery Atherosclerosis

Objectives: The objective of this study is to determine the frequency of carotidartery atherosclerosis using color Doppler ultrasound in ischemic stroke patients. StudyDesign: Cross-sectional study. Period: July 2015 to June 2016. Setting: Khyber TeachingHospital, Peshawar. Method: Doppler ultrasonography was done to assess carotid artery statusin patients diagnosed with cerebral infarction. Results: Data comprised of 174 ischemic strokepatients between ages 37-95 years. 111 were males whereas 63 were males. Mean age wasfound to be 64.03±11.71 years. Doppler ultrasound revealed carotid artery atherosclerosis in52.3% (n=91) patients with 57% males and 34% females. Right carotid artery involvement wasfound in 28 patients and left carotid artery involvment in 38 patients. Both carotid arteries wereinvolved in 25 patients. Conclusion: We have concluded that carotid artery atherosclerosis is anindependent predictor for future vascular events. Our study reports carotif artery atherosclerosisin 52.3% patients with ischemic stroke.
