Role of C.T. Scanning in Characterization of USG Detected Solid and Cystic Lesion of Liver.

The exact nature i.e. neoplastic vs. benign of USG detected space occupying lesions are confirmed by computed tomography. In this study we do CECT of 45 cases of sonographically detected space occupying lesions in liver. Some of cases which is very confusing in regards either it is benign or malignant, the computed tomography is more sensitive.

Role of Ultrasonography in the Diagnosis of Intrahepatic Space Occupying Lesions.

Ultrasonography is safe, non- invasive, cost-effective, less time-consuming, easily repeatable and simple investigation for the diagnosis and follow up of intrahepatic space occupying lesions. In these study ninety patients with a probable diagnosis of space occupying lesions of liver were studied. The diagnosis of intrahepatic space occupying lesions was confirmed in eighty-two patients. Ultrasonography had sensivity of 91%.

Role of CT in the Evaluation of Adult Brain Tumor.

Imaging plays an important role in the evaluation of patients with brain tumors. CT is an important and commonly used modality. They have a significant impact on patient modalities and care. The technical improvement of CT and the utility of contrast material in the imaging of brain tumors improved significantly the detection and the evaluation of brain neoplasms.Once a brain tumor is clinically suspected, radiologic evaluation is required to determine the location, the extent of the tumor and its relationship to the surrounding structures. This information is very important & critical in deciding among different forms of therapy such as surgery, radiation and chemotherapy. In this article we will give an overview of the role of CT in the diagnosis of brain tumors.

Study of Systolic/Diastolic Ratios of the Umbilical Artery Flow Velocity Waveforms in Pregnant Women.

Analysis of umbilical artery flow velocity waveforms of systolic/diastolic (S/D) ratio of 58 patients, who had accurately uncomplicated pregnancies with a normal spontaneous vaginal delivery, were studied. This study includes conventional ultrasonography, color flow mapping and duplex Doppler flow. There was a significant decrease in the S/D ratio over each week of the third trimester of pregnancy. The study present the mean, range and upper limit of the data obtained in this population.

Role of High Frequency US in Breast Imaging.

High frequency US probe is more informative of both spatial and contrast resolution with increase in the sensitivity of breast examination. A prospective study of 100 patients with symptomatic breast disease and negative X-Ray mammography were undertaken of 72 patients who were below 35 years of age. Ultrasonography was performed using high frequency (10-13MHz) annular phased array transducer. In 28 patients (28%) focal abnormalities were observed. 12 patients had nodular lesions (6 malignant), 14 had cystic lesions and 2 had galactasia. It is suggested that high frequency breast US is a useful tool in examination of symptomatic breasts, particularly in relatively younger patients.
