INTRODUCTIONThe commonest problem an obstetrician faces frequently is the assessment of fetal maturity for either prolonging the pregnancy or terminating it, for complications such as fetal distress, pregnancy induced hypertension, diabetes and Rh incompatibility diseases. The means that are widely accepted for estimating fetal maturity are Gestational age, weight of the fetus. The methods used to estimate gestational age (GA) and predict the expected date of delivery are menstrual history, clinical examination, perception of fetal movement and Nagele's rule.1 Nagele's rule is in women with regular cycles and certain LMP, the EDD is calculated by adding 7 days to the first day of the LMP and then adding 9 months. A menstrual history could be misleading for a number of reasons, such as, many women do not accurately recall the first day of last menstrual period, particularly if they are not trying to conceive. LMP may be unreliable or misleading because of oligomenorrhea, abnormal bleeding events, use of oral contraceptives and becoming pregnant in the first ovulatory cycle after a recent ABSTRACT Background: Assessment of accurate gestational age of fetus is very imperative for proper obstetric management of normal as well as IUGR pregnancies. The objective of this study was to evaluate the accuracy of transverse cerebellar diameter as against the conventional parameters of Biparietal diameter, head circumference, abdominal circumference and femur length in normal pregnant mothers between 15 to 40 weeks and in antenatal diagnosis of intrauterine growth retardation. Methods: Study done on 100 women attending antenatal department, 80 were normal pregnancy cases and 20 were clinically suspected IUGR cases. In each patient BPD, HC, AC, FL and TCD was measured. Correlation of TCD was done with other measured parameters as well as with estimated gestational age of fetus. Results: There was no statistically significant difference between the age and parity distributions of two groups It was seen that 18 cases were below the fifth percentile for AC and HC, 19 cases were below the fifth percentile for BPD and 16 cases were below the fifth percentile for FL. In 16 out of 20 cases the TCD values were within the normal range. Only in 4 cases the TCD values were below the 5 th percentile. This difference in number of cases below the 5
Background: Uretolithiasis is one of the most common cause of urinary tract obstruction which leads to the admission into the emergency ward. The detection of urolithiasis or acute renal colic is by the radiography, conventional ultrasonography (US) and intravenous urography (IVU). A colour Doppler USG measures this change as a resistive index (RI) of the arcuate arteries at the corticomedullary junction or the interlobar arteries.Methods: 84 patients between the ages 15-50 years, who were admitted to the Emergency department of our hospital with unilateral renal colic were included into our study. Detailed demographic data was collected from all the patients and they were all subjected to a thorough physical and clinical examination. Bladder ultrasound was taken along with color Doppler for all the patients at the time of admission for every 6 hours. Thus, an increased RI index signifies an obstruction without a dilatation.Results: Left flank pain was slightly more than the right flank pain, although this was not found to be significant. Most of the patients were presented with vomiting or nausea and dysuria was seen in 48 patients. there were 41 cases of hydronephrosis in total and all of them were positive for mean RI. The specificity with the mean resistive index with color Doppler was 90%, while the sensitivity was 100%. Around 95% of the prediction was accurate with mean resistive index, with more than 90% efficiency.Conclusions: The mean resistive index is a very good tool for the diagnosis of hydronephrosis, with a very high level of specificity and sensitivity.
Background: Trauma has become one of the most common cause of hospitalization. The main reason for imaging and screening the patients is to identify the life-threatening injuries as soon as possible so that appropriate treatment can be given immediately. In the past few years, both USG and CT have been widely used to detect the abdominal trauma and have replaced the older methods. This study was undertaken to compare the efficacy of CT scans and Ultrasound in the patients with blunt abdominal trauma.Methods: Patients who had come to our hospital with blunt abdominal trauma and who were stable enough to undergo both USG and CT scans were included into the study. Apart from routine tests, both USG and CT scans were performed for all the patients.Results: The most common cause of trauma was road or vehicular accidents (58.9%) followed by fall from heights (32.1%). Of the organs which were affected, the most one was liver (73.2%), followed by spleen (51.8%), 46.4% of kidneys and 12.5% of the pancreas. Hemoperitoneum was identified in all the 56 patients with CT scan while the same was identified only in 47 cases (83.9%) with USG.Conclusions: CT scan is a superior diagnostic tool for the detection of Blunt abdominal trauma compared to USG. However, the patient needs to be hemodynamically stable for CT to be performed.
Background: In order to conduct appropriate surgical treatments, the characterization of ovarian lesions is of considerable significance and can affect patient care. A multidisciplinary approach based on physical assessment, laboratory tests and imaging techniques includes adequate measurement of the adnexal masses. The aim is to assess the role of Sonography and MR in diagnosing ovarian masses, to study imaging characteristics of ovarian masses on USG and Doppler in correlating these findings with MR features. Subjects and Methods: The present study was carried out in the department of radiodiagnosis to determine the efficacy of sonography and MRI in the diagnosis of ovarian masses. The study group comprised 50 patients with clinically suspected ovarian masses and imaging was carried out on all patients with ovarian masses and imaging was carried out on all patients with ovarian masses. All the masses were evaluated on sonography based on the Sassone scoring system. Morphological analysis was performed for each mass based on wall thickness, inner wall structure, septal structure and echogenicity of mass. The color flow was carried out, subsequently; MRI was carried out for each patient. Radiological diagnosis was confirmed after surgery on histopathological examination. Results: The majority of the patients were in the age group of 31-40 years. The most common symptoms noted were pain in the abdomen. The most common clinical finding was a palpable mass. The application of Sassone sonomorphologic score >9 was identified in 8 masses, out of which 7 were malignant and 1 was a benign lesion. The colour flow was detected in 38 out of 50 masses. The presence of flow, type of flow, vessel arrangement, morphology and location were noted and on pulsed Doppler the RI and PI values were calculated. Out of 8 malignant cases, 5 were diagnosed as malignant according to the Caruso score. The overall sensitivity 100 %, specificity is 97.6% and diagnostic accuracy is 98% of MRI which is higher than that of ultrasound and CDS. Conclusion: We conclude that MRI is a superior diagnostic modality in establishing the diagnosis of ovarian masses.
