Background: Head injury is considered as a major health problem that is a frequent cause of death and disability and makes considerable demands on health services. CT remains essential for detecting lesions that require immediate neurosurgical intervention as well as those that require in-hospital observation and medical management. Objectives:To evaluate the computed tomography findings in patients sustaining head injury and to emphasize the importance of computed tomography scan in head injury. Methodology:The study was conducted for the period of one year .It comprised a total number of eighty patients presenting to the emergency room(ER) with head injury and were evaluated by CT scan of head using siemens somatom dual slice spiral CT machine.Results: the study showed overall male to female ratio as 2.6:1. Head injury was most common in 31-50years of age group. Road traffic accidents (RTA) was the commonest mode of injury seen in 65% of patients.Loss of consciousness followed by vomiting and seizures were the common clinical presentations in head trauma patients respectively.According to Glasgow coma scale( GCS) , most of the patients (68.8%)sustained mild head injury( GCS13-15) . Most common abnormal CT findings were skull fractures 39(48.8%), extradural hematoma 31 ( 38.8%), subdural hematoma 21(26.2%) ,contusions 21(26.2%) , subarachnoid hemorrhage14 ( 17.5%) and pneumocephalous 13 (16.2%) respectively. Linear skull fracture was the commonest among all other skull fractures.Patients sustaining severe head injury were mostly due to RTA (77%). The highest mortality was seen in patients with severe head injury (GCS 3-8). 5% also had cervical spine injury. Conclusion:CT is the most comprehensive diagnostic modality for accurate localization of the site of injury in craniocerebral trauma. The early and timely diagnosis of the precise lesion by CT not only had the substantial impact over instituting appropriate treatment and timely surgical intervention but also helped in predicting the ultimate outcome.

Introduction: We presume that the knowledge of patients about Magnetic Resonance imaging (MRI) scan is of utmost importance for smooth workflow, patient comfort, patients’ safety and to mitigate patients’ compliance and save valuable scan time. Therefore, the purpose ofthis study was to determine the awareness of patients undergoing MRI scan regarding Knowledge, Perception and Safety. Methods: This descriptive cross-sectional study was carried out in Chitwan Medical College Teaching Hospital from April to September, 2018. Total of 310 patients referred to undergo MRI scan were assessed by a questionnaire form covering 4 parts: Part 1- aimed to gather the socio demographic data such as age, sex, occupation and educational status of patients, Part 2- included the knowledge regarding MRI and its safety, Part 3- comprised the patient perception before MRI scan and Part 4 constituted the patient perception after MRI scan.The form was filled by an investigator oneself in a face to face interview with the patients. Results: Among 310 patients, 35.2% were illiterate and 19.4% graduated from high school. Majority of 85.5% patients answered that MRI uses harmful ionizing radiation like CT scan and radiography. Almost 43 patients who answered MRI functions in disease treatment also answered decreased in pain after MRI scan (Male = 15 and Female = 28) were in age group between 25 years and 50 years. This study also revealed that majority of 26.8% (i.e. n = 83) patients faced problem as claustrophobia along with anxiety during the scan, out of which 13 patients have history of previous MRI scan. Conclusions: In our study decrease in pain was higher in diagnosis and treatment answer. Majority of the patients faced anxiety along with claustrophobia during the MRI scan. Assessment of patient knowledge, perception and safety regarding MRI scan can be the key to increase patient compliance and save valuable scan time.
