Background and Objectives:Nepal is facing the problem of safe, effective and quality radiology services due to lack of adequate knowledge towards advance technology in health sector professionals. Therefore, the present study was designed to focus on the knowledge, attitude and practice on radiation among employee in selected hospitals. Material and Methods:This is a descriptive cross-sectional study conducted in among technical and non technical staff that were involved in or come across the radiology department. A set of self structured questionnaire and observation was used for data collection. Purposive sampling technique was used for the data collection. The collected data was compiled and analyzed by using SPSS 16. Results:The total number of staff participated in this study were 113, among them 65(58%) belong to technical group as health Professionals and 48(42%) belong to non-technical group. The knowledge of the technical staff was 66.95%, perception was 87.65% and the having the practice of protection was 75.9% whereas in non-technical staffs were 53.46%, perception is 64.60% and the having the practice of protection is 53.74%. Conclusion:The overall knowledge of radiation exposure amongst technical and non-technical staffs was average, poor perception and satisfactory practices. Regular training programmes and national legal law should be processed to reduce malpractice in radiations.

“…Previous studies obtained contralateral radiographs of the uninjured knee to compare the sagittal plane with the injured side by superimposing the outline contours 16 or defined axis by CT. 17 Both procedures should be avoided according to increasing radiation risk awareness. 18 The purpose of this study was to determine consistent sagittal landmarks and measurements of the distal femur that could be used intraoperatively and postoperatively to define correct sagittal alignment. Defining the correct sagittal alignment will assist future research in the evaluation and communication of distal femoral fractures treated with laterally based plates or intramedullary nails.…”

The necessity for reliability and quality of intraoperative and postoperative radiographic controls of the obtained fracture reduction, implant insertion, and final healed fracture increases with popularity of less invasive indirect reduction and stabilization methods. The ability to obtain exact sagittal alignment measurements has been problematic with other studies. Two different and reliable methods of measuring sagittal plane anatomy and measurements independent of implants were confirmed using plain radiographic images.

“…3 Unfortunately, physicians may not fully understand how CT scanning affects a patient's future risk of cancer. 4 Published estimates of CT radiation dose vary considerably. Several national surveys of CT use in the United Kingdom report doses on older CT scanners, mainly single-slice CT. 5 Newer CT scanners use multiple detectors and have faster scanning times, allowing advanced applications, such as CT angiography.…”

Objectives: Computed tomography (CT) use is increasing in the emergency department (ED). Many physicians are concerned about exposing patients to radiation from CT scanning, but estimates of radiation doses vary. This study's objective was to determine the radiation doses from CT scanning for common indications in a Canadian ED using modern multidetector CT scanners. Methods: We conducted a health records review of consecutive adult patients seen at two busy tertiary care EDs over a 2-month period who underwent CT scanning ordered by emergency physicians. Cases were identified by searching an imaging database. Data collected included patient age and sex, study indication, scanner model, body area, and reported dose-length product. Effective dose per scan was calculated from reported dose-length product. Data were collected on a standardized form, entered into an electronic database, and analyzed with descriptive statistics and 95% CIs. Results: During the study period, emergency physicians assessed 19,880 patients. Overall, 2,720 (13.7%) underwent CT scanning, and of these, 144 (5.3%) patients had more than one scan. Patients had a mean age of 59.0 years, and 45.3% were men. Mean doses for the most common indications were as follows: simple head, 2.9 mSv; cervical spine, 5.7 mSv; complex head, 9.3 mSv; CT pulmonary angiogram, 11.2 mSv; abdomen (nontraumatic abdominal pain), 15.4 mSv; and abdomen (renal colic), 9.8 mSv.Conclusions: Approximately one in seven ED patients had a CT scan. Emergency physicians should be aware of typical radiation doses for the studies they order and how the dose varies by protocol and indication. RÉ SUMÉObjectif: Le recours à la tomodensitomé trie (TDM) est à la hausse dans les services d'urgence (SU), et l'exposition des patients au rayonnement des appareils de TDM pré occupe bon nombre de mé decins, mais les estimations des doses sont variables. L'é tude visait à dé terminer les doses de rayonnement é mises par des appareils modernes de TDM à dé tecteurs multiples, utilisé s dans un hô pital, au Canada, dans des indications courantes. Mé thode: Nous avons procé dé à un examen des dossiers mé dicaux d'adultes consé cutifs, qui ont é té examiné s dans deux SU de soins tertiaires, ayant une forte fré quentation, sur une pé riode de 2 mois, et qui ont subi un examen par TDM à la demande d'urgentologues. La recherche de cas s'est faite dans une base de donné es d'images. La collecte de donné es comprenait l'âge et le sexe des patients, les indications de l'examen, le modè le d'appareil, la ré gion du corps, ainsi que le produit dose-longueur indiqué . La dose efficace par balayage a é té calculé e à l'aide de ce produit dose-longueur. Les donné es ont é té recueillies sur un formulaire normalisé , inscrites dans une base de donné es é lectroniques, puis analysé es à l'aide de statistiques descriptives et d'intervalles de confiance à 95%. Ré sultats: Durant la pé riode à l'é tude, 19 880 patients ont é té examiné s par des urgentologues; 2720 (13.7%) d'entre eux ont subi une TDM, ...
