Background:Thyroid nodules are common presentation in patients having thyroid disorders. There is approximately 4-5% incidence of clinically apparent thyroid lesions in general populations.Thyroid nodules are about four times more common in females than in males. The present study aims to diagnose the thyroid lesions and evaluate to relation and diagnostic test of ultrasonography (USG) and Fine Needle Aspiration Cytology (FNAC) report. To determine the sensitivity of ultrasonography in detecting thyroid lesions.Method:This was hospital based prospective study carried in 94 patients who came to radiology department for USG neck, after clinical examination frommedicine, surgery and ENT department.Those patients with thyroid lesions were followed and advised for USG guided FNAC of thyroid swelling. The patients who were advised for FNAC, and gave consent for procedure were included in the study. The USG guided FNAC was done and wasfurther evaluated by pathologist. Results:Out of 94 cases, 85 were benign nodules and 9 were malignant nodules by USG which were further confirmed by FNAC with results of 87 benign and 7 malignant.The USG diagnosed the benign thyroid nodule with sensitivity of 96.55% and specificity of 85.71%, positive predictive value 98.82%, negative predictive value 66.67%, accuracy 95.74%. The result revealed that there is a strong relation between diagnoses of benign thyroid lesions by USG and final diagnosis by FNAC (P=0.001).Conclusion:High resolution grey scale imaging features can differentiate benign and malignant lesions. USG is very helpful for FNAC, characterization of nodules and provides differential diagnosis in those patients affecting with thyroid disorders.

Introduction: Placental thickness (PT) plays vital role when the menstrual age is not known. The present study was undertaken to calculate the Placental thickness at level of insertion of umbilical cord and correlate it with gestational age and fetal weight, subsequently establishing a nomogram for Placental thickness at different age of gestations. Materials and Methods: A total of 300 antenatal women from 12 to 40 weeks of gestation with singleton pregnancy and with no high-risk factor were included in the study from October 2021 to July 2022. Ethical approval was taken from institutional review committee (Ref. F-NMC/541/078-79). A detailed history was taken from all the patients. Basic antenatal investigations, clinical and ultrasonography examination were done.  Results: In present study the mean age group of pregnant women was 23.92 ± 4.456 years with mean age of gestation to be 28.18 ± 7.450 weeks. Most common location of placenta is found to be Anterior (32%). There is very strong correlation between placental thickness with gestational age r=0.987 and estimated fetal weight r=0.873. P-value was 0.001 in both. Conclusion: Ultrasonographic measurement of Placental thickness, gestational age and estimated fetal weight play a vital role in antenatal care. Thus, with advancing gestational age; placental thickness measurement can be an additional tool to determine gestational age and fetal weight. Any deviation from normal value can prompt to any developing abnormalities.
