Worldwide, variation exists in normative studies for both these indices. The majority of research for EI and BCI is based on data from the Western population. The study has been performed on the South Karnataka population. Aims and Objectives: This study’s goal is to derive age and gender specific cutoff values on normative data of Evans and BCI. Materials and Methods: This was a prospective and observational study.Patients referred to “RL Jalappa Hospital” for computed tomography (CT) scan of the brain who meet the inclusion criteria will be included in this study. CT brain of all the patients will be performed in Siemens Somatom emotion 16 slice CT scanner. Ninety-seven were selected for this study, and EI and BCI were calculated for them. Results: The mean value of EI and BCI in our study was 0.26±0.02 and 0.1167±0.02, respectively. The difference in EI and BCI between males and females shown significant statistical difference between males and females but the values increased as increase in age. Conclusion: Our study for South Indian population concludes that EI and BCI have a significant statistical difference between males and females. Both EI and BCI values increase with age. Hence cutoff values of EI and BCI index according to age and gender are important for evaluation of hydrocephalus.

Aims and Objectives: This study is hospital-based observational study to derive normal measurement range of fourth ventricle and correlating it with measurements of cerebrum and age of patients. Materials and Methods: Hospital-based prospective study was conducted in the department of radiodiagnosis in a teaching medical college. Patients with virtually normal study on unenhanced head CT scan of both sex and age groups from 2 year to 60 years, were included in the study. Patients with CT scans showing gross pathological changes affecting the normal anatomy of ventricles were excluded from the study. Results: The mean age of the cases was 37.0±16.88 years. Mean fourth ventricle anterioposterior dimension is 7.5±2.5 mm and transverse dimension is 12±3.1 mm. Anteroposterior diameter of fourth ventricle showed non-significant correlation (r=0.06, P=0.56) with anteroposterior diameter of skull and no significant correlation with (r=0.07, P=0.45) transverse diameter (TD) of skull. AP diameter of fourth ventricle showed a positive correlation with age, which was statistically significant (r2=0.698, P=0.01). TD of fourth ventricle showed slight positive correlation (r=0.202 P=0.048) with anteroposterior diameter of skull and (r=0.142, P=0.168) TD of skull whereas nil with. TD of fourth ventricle showed a positive correlation with age, which was statistically non-significant (r2=0.659, P=0.01). It increases with age. Conclusion: Knowledge of normal measurements helps in assessing, dilated fourth ventricle in various pathologies.

In the periand postmenopausal age group, it accounts for more than 70% of all gynecological complaints. The current study's objective was to compare the effectiveness of MRI and ultrasonography (USG) in detecting the cause of abnormal uterine bleeding with pathological correlation. Material and methods We conducted an observational study involving subjects with abnormal uterine bleeding. Patients who presented with abnormal uterine bleeding were referred to the department of radiodiagnosis and underwent USG of the abdomen and pelvis, followed by an MRI of the pelvis. Findings were analyzed and compared with the histopathological examination (HPE) of the samples of hysterectomized uterus, polypectomy, myomectomy, and dilation and curettage (D&C) of the endometrium. Results Among the study population, USG reports showed two patients (4.10%) with polyps, seven patients (14.58%) with adenomyosis, 25 patients (52.08%) with leiomyomas, and 14 patients (29.16%) with malignancies. On MRI examination, three patients (6.25%) were diagnosed with polyps, nine patients (18.7%) with adenomyosis, 22 patients (45.8%) with leiomyomas, and 14 patients (29.16%) were reported to have malignancies. The measure of agreement with the kappa value for MRI and HPE in evaluating the causes of abnormal uterine bleeding is 1.0 (very good). Whereas the kappa agreement value of USG and HPE in evaluating the causes of abnormal uterine bleeding is 0.903 (acceptable). The sensitivity of USG in diagnosing polyps, adenomyosis, leiomyoma, and malignancy was observed at 66%, 77.78%, 100%, and 100%, respectively. The sensitivity of MRI in diagnosing polyps, adenomyosis, leiomyoma, and malignancy was 100% for each. Conclusion MRI is the most effective method for accurate identification of the location, number, and characterization of lesions, extensions, and staging of carcinomas.

This study was done to compare the estimated fetal weight determined by Hadlock’s method and Scioscia’s formula (using femur length and mid-thigh soft-tissue thickness [MTSTT]) to the actual birth weight (ABW). Aims and Objectives: The objectives of this study were as follows: (1) To estimate fetal weight by Hadlock’s method and ultrasonographic evaluation of fetal MTSTT in late third trimester. (2) To correlate fetal weight derived by Hadlock’s method and ultrasonographic evaluation of fetal MTSTT with ABW. Materials and Methods: The study was conducted during the period November 2022–January 2023, at Sri Devaraj Urs Medical College, Tamaka, Kolar. Seventy-six pregnant ladies at term (between 37 and 40 weeks) were included in the study. Results: This study assessed validity of Hadlock formulae and Scioscia’s formulae for detecting fetal weight. For detection of fetal weight by Hadlock’s method, area under curve (AUC) was 0.961 and according to Scioscia’s formulae, AUC was 0.965. This study showed good agreement between fetal weight derived by Hadlock formulae and actual fetal weight (Kappa value – 0.725). There was also good agreement between fetal weight derived by Scioscia’s formulae and actual fetal weight (Kappa value – 0.745). Conclusion: The fetal weight derived by Scioscia’s formula was comparable to the actual fetal weight allowing us to rely on Scioscia’s formulae to detect fetal weight. Calculating fetal weight by measurement of fetal MTSTT serves as an additional tool for estimation of fetal weight along with the existing parameters, thereby increasing the likelihood for accurate fetal weight estimation.
