Introduction: Trauma is the most common worldwide cause of death and disability in young adults. Neurotrauma is one of the most frequent indications for emergent neuroimaging because imaging plays such a key role in patient triage and management.

Introduction The thyroid gland is the largest of all endocrine glands and is the only one which is amenable to direct physical examination and high resolution real-time grayscale sonography because of its superficial location. High Resolution Ultrasonography (USG) with Color Doppler is used to assess the nature of the lesion according to its vascularity and also the hemodynamic characteristics of the gland. Thus, the combination of Gray scale Sonography and Color Flow Doppler provide huge benefits and help in increasing the sensitivity, specificity and accuracy in distinguishing benign and malignant thyroid nodules. Nearly 50% of patients with a clinically palpable solitary thyroid nodule have avoided surgery because of thyroid ultrasound. Aims and objectives The present study is aimed to determine the role of high resolution USG in the evaluation of lesions of the thyroid with Fine-needle aspiration cytology (FNAC) correlation and compare it with other studies. Materials and methods This is a prospective study carried out on 50 patients (44 female and 6 male) who attended ENT or Surgery outpatient department/inpatient department (OPD/IPD) and were referred to the Department of Radio-Diagnosis for high resolution USG of neck at Rohilkhand Medical College and Hospital, Bareilly, Uttar Pradesh, India. This study was conducted for a period of one year from March 2015 to February 2016. The ultrasound machine used was GE LOGIQ V5. Result and Conclusion Our present study consisted of 50 cases which were clinically suspected suffering from thyroid dysfunction. Thyroid ultrasound was very efficient in picking up lesions in all 50 cases in our study. In comparison, to other studies our study gave a similar picture in terms of benign lesions being much more common than malignant lesions. The most common benign lesion determined in our study was colloid goiter which was the most common benign lesion in many other studies. In comparison to other studies, we were able to detect malignant nodules with a better specificity. Chronic thyroiditis was also very efficiently detected using ultrasound in our study.

Objective: The objective of our study was to evaluate the role of ultrasound in the evaluation of patients with first trimester bleeding and to prognosticate and predict the status of abnormal pregnancies. Materials and methods:We studied 50 cases of pregnant women who presented with bleeding per vaginum during the first trimester between November 2015 and August 2016. The main sources of data for this study are patients from teaching hospitals attached to Rohilkhand Medical College & Hospital, Bareilly, Uttar Pradesh, India. All patients referred to the Department of Radiodiagnosis with clinically suspected first trimester bleeding were evaluated with clinical history, clinical examination, and ultrasonography (USG). Ultrasonographic examination of patients was done using the following machines:(1) Phillips 350, (2) G.E. logiq V3, and (3) Toshiba 1000. Results:Of the 50 cases of first trimester bleeding, 26 cases were diagnosed as threatened abortion clinically, out of which only 12 cases were confirmed. Ultrasound examination confirmed 12 cases of clinically suspected threatened abortions and aids in correctly diagnosing 8 cases that were missed on clinical examination. A total of 12 cases out of 18 threatened abortions continue to term gestation with a successful outcome of 66%. All cases of threatened abortion (n = 18), incomplete abortion (n = 10), missed abortion (n = 4), ectopic pregnancy (n = 4), inevitable abortion (n = 4), blighted ovum (n = 2), and hydatidiform mole (n = 2) were correctly diagnosed on USG. A total of 48 out of 50 cases were correctly diagnosed on ultrasound compared with 18 out of 50 cases on clinical diagnosis, with a disparity of 64%. Four out of five proved ectopic pregnancies were correctly diagnosed both on ultrasound and on clinical examination. Conclusion:Ultrasound is noninvasive, nonionizing, without any proved harmful effects on the developing fetus and easily available method of investigation to assess the patients with first trimester bleeding, which is highly accurate in diagnosing the actual causes of bleeding and guides the clinician in choosing the appropriate line of management and prevents mismanagement of the cases. In the present study, 48 out of 50 cases were correctly diagnosed on ultrasound compared with 18 out of 50 cases on clinical diagnosis, with a disparity of 64%.
