Background: Mammography is used for the detection of breast cancer. Objective: The purpose of the present study was to evaluate the diagnostic performance of Mammography in the diagnosis of benign and malignant breast mass. Methodology: This cross-sectional type of study was carried out in the Radiology & Imaging department of Sir Salimullah Medical College and Mitford Hospital, Dhaka, during July 2013 to June 2015. Patients clinically suspected as having breast mass, referred in the above mentioned hospitals and enrolled for surgical management were included in this study. Mammography were done in all these patients and they were followed up from the admission up to the post-operative tissue diagnosis of breast mass in respective pathology departments for histopathological correlation. Results: A total of 41 patients had mass among them, 3(7.3%) cases were malignant and 38(92.7%) cases were benign patients. Histopathological diagnosis of invasive ductal carcinoma, invasive lobular carcinoma and medullary carcinoma were 8(14. %), 4(7.00%) and 1(1.8%) respectively. Mammography malignant was found 14 cases out of which 10(76.9%) malignant and 4(9.1%) benign evaluated by histopathology. Mammography benign was found 43 cases out of which 3(23.1%) malignant and 40(90.9%) benign evaluated by histopathology. The sensitivity was 76.9%, specificity 90.9%, accuracy 87.7%, positive predictive values 71.4% and negative predictive values 93.0% in mammography. Conclusion: Mammography is highly sensitive, specific, reliable and useful method in the differentiation of malignant and benign breast masses.

Introduction: The prostate is an accessory gland of the male reproductive system. It can be involved by a number of diseases ranging from inflammation to malignant diseases. Most common causes of prostatomegaly are benign prostatic hyperplasia, prostatitis, intraprostatic and periprostatic cyst, prostatic adenocarcinoma. Objectives: To evaluate the diagnostic usefulness of Transabdominal ultrasonography in enlarged prostate and compare the USG findings with the histopathological findings. Method: This cross sectional study was carried out in Radiology and Imaging Department of Sir Salimullah medical college and Mitford hospital, Dhaka, from January 2014 to December 2015 with clinically suspected enlarged prostate by department of Urology and referred to the Radiology and Imaging Department for proper evaluation whether benign or malignant by Trans-abdominal ultrasonography before treatment planning and further management. Results: In this study, mean age was 65. 8 years with standard deviation of mean ± 9. 7 years and the age ranged from 50 to 89 years. The most common symptoms associated with enlarged prostate were incomplete emptying 90%, frequency 84%, intermittency 80% urgency, 76%, weak stream, 70% straining 66%, nocturia 60%. Out of 50 patients, histopathological diagnosis of 44 (88%) was nodular hyperplasia, 2 (4%) was nodular hyperplasia with chronic prostatitis and rest of 4(8%) was adenocarcinoma of prostate. Conclusion: Ultrasonography is a non-invasive, available, radiation free procedure, which is used as a first line preliminary diagnostic procedure.
