We studied requested urgent Brain CT Scan procedures justification. In addition, we addressed referrer’s (physician’s) awareness of radiation risks. In doing so, we considered two aspects to the issue. First, we reviewed the records of the requested urgent CT scan procedures for a sample of 339 patients at Al-Maqassed Hospital, a major hospital in Palestine. Secondly, we surveyed a sample of forty-two referrer’s from the same hospital to test their awareness of radiation risks. Our study shows that out of the 339 urgent brain CT requests, 69.6% were justified requests and 30.4% were unjustified. On the other hand, our survey on referrers shows that 42% of respondents knew the effective dose of a brain CT scan, 24% of respondents knew the radiation risks and 14% of respondents knew about radiation protection. Although the study is limited, yet it shows the need to reduce the number of brain CT examinations and the need to improve their justification. Consequently, the need for regular education and guideline implementation at least in this country is of paramount importance

Brain Ct Scan

BACKGROUND: In emergency medicine for determining the intracranial injury (ICI) in children with head trauma, usually brain CT scan is performed. Since brain CT scan, especially in children, has some disadvantages, it is better to find a procedure which could help to choose only the children with real head trauma injury for brain CT scan.AIMS: The aim of this study is to find such procedure. This study was descriptive, analytic and non-interventional.METHODS: We reviewed the archived files of children with head trauma injuries referred to the emergency department of Imam Hossein Hospital within two years. Patientâ€™s CT scan findings and head trauma risk factors were evaluated in this study.RESULTS: Out of 368 patients, 326 patients had normal brain CT scan. 28 of them showed symptoms of ICI consisting intraventricular haemorrhage (IVH), contusion, subarachnoid haemorrhage (SAH), subdural haemorrhage (SDH), epidural hematoma (EDH), and pneumocephalus. Twenty-seven patients showed skull FX, which 14 of them had an Isolated fracture, and 13 of them also showed symptoms of ICI. Since patients with isolated FX usually discharge quickly from Emergency Department; their data did not include in results of the study. The patients have been divided into two groups: 1- ICI, 2- without ICI. RR (relative risk), CI (Confidence interval) and sensitivity, positive predictive value (PPV), negative predictive value (NPV) and association of these risk factors with ICI were assessed with the Chi-2 test. In the end to determine the indications of CT scan, the presence of one of these five risk factors is important including abnormal mental status, clinical symptoms of skull FX, history of vomiting, craniofacial soft tissue injury (including subgaleal hematomas or laceration) and headache.CONCLUSIONS: For all other patients without these risk factors, observation and Follow Up can be used which has more advantages and less cost.

Medical imaging with ionizing radiation in pediatric patients is rising, and their radiation sensitivity is 2–3 times more than adults. The objective of this study was to estimate the total effective dose (ED) of all medical imaging by CT scan and plain radiography in patients in pediatric neurosurgery department. Patients with at least one brain CT scan and recorded dose length product (DLP) were included. Patients’ imaging data were collected from the picture-archiving-and-communicating system (PACS) using their national code to find all their medical imaging. Total ED (mSv) from CT scans and plain radiographs were calculated. A total of 300 patients were included, of which 129 were females and 171 males with a mean age of 5.45 ± 4.34 years. Mean DLPs of brain, abdomen, and chest CT were 329.16, 393.06, 284.46 mGy.cm. The most frequent CT scans in these children were brain CT scans with ED range of 0.09 to 47.09 mSv. Total ED due to all CT scans and plain radiographs were in the range of 0.38 to 63.41 mSv. Although the mean DLP of each brain, chest, and abdomen CT of patients was in the range of DRLs reported by previous studies, the patients with numerous CT scans received more radiation doses than mean ED (6.21 mSv between all age groups). The most frequent CT scan was the brain, and the most frequent plain radiographs were chest and lower extremities. It can be concluded that reducing the number of CT scans or plain radiographs by appropriate physical exams or replacing them with modalities that do not use ionizing radiation can reduce ED.
