Currently Breast Imaging Reporting and Data System used in risk stratification and guide management. This method reduces unnecessary fine needle aspiration cytology rates, benefiting patients and the healthcare system by reducing burden. Objective: This study aims to determine the effectiveness of ultrasound-based risk stratification by correlating ultrasound findings and pathologic diagnosis at Jimma University comprehensive specialized hospital. Method: Hospital based retrospective cross-sectional study design was conducted on radiologic-pathologic correlation study in patients with ultrasound examination for breast nodules classified based on their American College of Radiology Breast Imaging Reporting and Data System score at Jimma University comprehensive specialized hospital, radiology department from March 2025 to August 2025. Descriptive statistics and Chi-square tests were used to measure the strength and direction of the association between variables. Finally results will be presented in the form of texts, graphs and tables and finding of this result will be disseminated to all relevant stakeholders through presentation and publication. Results: Out of 81 breast nodules examined on ultrasound 65 nodules belonged to BIRADS 3 while 3 and 13 nodules belonged to BIRADS 4 and 5 respectively. On FNAC: 3 were found to be IAC Yokohama C1, 59 were C2, 5 were C3, 4 were C4 and 10 were C5. The sensitivity, specificity, PPV and accuracy value of ultrasound were found to be 92.8%, 95.5%, 81% and 96.2% respectively.

Ultrasound based risk stratification is a widely used method currently helping to guide management in patients with thyroid nodules; which are common and mostly benign. The use of these risk stratification methods has helped to reduce unnecessary FNAC rates, therefore, reducing the burden both on patients and the health care system. Objective: The objective of our study was to determine the effectiveness of ultrasound-based risk stratification by correlating ultrasound findings and pathologic diagnosis at Jimma University Medical Center (JUMC) Method: Hospital based descriptive cross-sectional study was conducted that recruited 85 patients with thyroid nodules. Pearsons’s correlation was used to establish a relationship between TIRADS and cytology findings. The diagnostic accuracy of TI-RADS was assessed using sensitivity, specificity, positive predictive values, and accuracy Results: Of 85 study participants, 74 (87.1%) were females, and the mean age was 48.16 ± 15.03 years. Three quarters of the thyroid nodules 64(75.3%) were solid or almost solid, 72(84.7%) were shaped wider than tall, 77 (90.6%) had smooth margins, 56(65.9%) were hyper echoic or isoechoic, and 42 (49.4%) had no echogenic foci. TI-RADS 3 was the most common at 42(49.4%). The proportions of malignancy for TI-RADS 3, TI-RADS 4 and TI-RADS 5 were 4.8%, 20.0% and 77.8% respectively. The correlation between ACR TI-RADS and the Bethesda system of thyroid classification scores was r = 0.622. The sensitivity, specificity, positive predictive values, and accuracy of ACR TI-RADS were 88.9%, 59.7%, 37.2%, and 65.9%, respectively. Conclusion: We found that ACR TI-RADS classification is an appropriate and noninvasive method for assessing thyroid nodules in routine practice. It can safely reduce the number of unnecessary fine-needle aspiration in a significant proportion of benign thyroid lesions. ACR TI RADS should be standardized as the screening tool in resource-limited areas.

Gemechis Asefa; Wondim Getnet; Tsegaye Tewelde Radiologic Diagnostic and therapeutic procedures using ionizing radiation carries well-known potential health risks. The knowledge of the referring physician and patients on modalities of diagnostic imaging and procedures that use ionizing radiation varies widely. Their knowledge was generally inadequate. Patients’ radiation knowledge strongly influences their acceptance and preference of diagnostic imaging types. Objective: The main objective of the study is to assess knowledge on ionizing radiation associated hazards and protective measures during medical imaging among patients waiting for common radiologic imaging in Jimma University Specialized Hospital (JUSH), Ethiopia. Methods: Hospitals based cross sectional study design were conducted on 388 patients waiting for common radiologic imaging and procedures in JUSH, at radiology department. A structured questionnaire was used to collect data from voluntary patients. Data was cleaned, edited and entered to SPSS version 16.Data was expressed as frequency distribution and percentages. Categorical variables were compared using the chi-square test for association. A P value of less than 0.05 was considered statistically significant. Results: A total of 386 voluntary patients were included, of which 225(58.3%) of them were male. Their age range was from 14 years to 85years. In 28.2 % importance of imaging and likely associated harmful effects of radiation were discussed with referring physician. All of imaging unit referral was by the physician. An half of the respondents 193(50%) had back ground information about radiation. The majority of the participants, 356(92.2%) responded that they knew conventional x-ray. Twenty nine (7.5%) patients did not indicate any one of the equipment. Only 203 (52.6%) patients indicated the association health hazard with radiation. Sixty five (16.8%) were incorrect in their assumption that ultrasound examinations uses of ionizing radiation and 32 (8.3%) of them were not aware of ionizing radiation free nature MRI imaging. Majority of the patients 152(39.4%) had indicated infertility followed by cancer, 130 (33.7%) as specific health effect of ionizing radiation. About 122(31.6%) of patients indicate gonads as highly sensitive organ. Ultrasound and MRI indicates as safe modality during pregnancy in 32(8.3%) and 4 (1%) respectively, where as plain abdominal x-ray and CT as safe for pregnant mother in 4(1%) and 5 (1.3%) respectively. More than 95% of the respondents had no idea about background radiation and radiation protection symbol was known only among 15 (3.9%) patients. A large number of patients 292 (75.6%) responded that they had no idea about protective measures while diagnostic imaging. Most of (96.1%) the patients had no idea about the application of radiation rather than for their imaging purpose use. An association of effect the education and information on patients’ knowledge about radiation was revealed. Conclusion This study has shown the inadequacy of patients’ knowledge on possible radiation associated health hazards, radiation protection measures and applications of radiation that is in general agreement with the results of other similar surveys. Thus intervention should be done on the line of improving our patients’ knowledge about radiation issue.

Liver cirrhosis, whatever the primary cause, is the commonest cause of portal hypertension. Because of its accessibility, lack of ionizing radiation and rapid assessment, sonography plays a major role in the assessment of portal hypertension. Even if the additional use of color and spectral Doppler improves the assessment of patients suspected of having portal hypertension, gray scale assessment of portal vein diameter is corner stone in the initial evaluation. Therefore knowing the normal portal venous dimension in a study population of interest is so crucial. Objective: The main objective of the study is ultrasound assessment of normal portal vein diameter in Ethiopians patients visiting Jimma University Specialized Hospital. Methods: A prospective cross-sectional study was done at Jimma University Specialized Hospital to sonographically assess the normal portal vein diameter pattern. Data were collected from patients visiting radiology department on consecutive bases from Dec- Jan, 2014 and analyzed using spss version 16 Result: A total of 195 patients were included on the study, 75(38.5%) were females while 120(61.5%) were males. Mean PVD in quiet respiration and in the extremes of respiration was almost the same, 10.3 +1.8mm and 10.66+1.8mm respectively. The mean of portal vein diameter in Male were 11.10 +1.7mm and of Females were 10.1 + 1.5 mm ,and there p-value =0.096. Nineteen (10%) of participants had mean portal vein diameter of greater than 13mm (above normal) while 176(90%) had less than 13mm (normal range). There is significant variation of PVD with age but not with sex. The Pearson correlation between them was correlated at 0.001. Conclusion: The mean portal vein diameter of the majority of the participants was comparable with many other study results and can be used as a base line for further related studies and workup of the causes of abnormally high portal vein diameter noted in this study Sun, 01 Mar 2015 00:00:00 GMT https://repository.ju.edu.et//handle/123456789/3955 2015-03-01T00:00:00Z
