Background:-Prolapsed Intervertebral Disc (PID) is a major cause of disability in developing countries. Aims: The study aimed to investigate the awareness of disc prolapse (DP) among people in Taif city, Saudi Arabia. Settings and Design:-Descriptive cross section study was conducted in different areas in Taif(Taif University, schools, Mall and hospitals)during the period from September to December 2015. Methods and Material:-Thisstudy was done to a sample of 1034 people living in Taif were selected randomly at different areas. A structured questionnaire was designed for data collection by researchers based up on review of literature. It includes 4 parts:The socio-demographic data, Knowledge and awareness about risk factors of (DP), Knowledge of participant about diagnosis of (DP) and Knowledge of participants about protection from (DP). Results:-The sample distributed to 716 (69.2%) male and 318 (30.8) female with common age group 18-28 years by percentage (52.8%), most of participant were Saudi 972 (94.0%) and Universal and education level(60.2%), the married and employee participant represent (51.8%), (50.1%) respectively with office occupation type. Most of sample haven't complaining of (DP) with percentage (81.4%) and (53.8%) of participant have no family history, (66.5%) of participant heard about (DP) and most of them have an information about the risk factors of (DP) with highest percentage (81.6%) regard diagnosis of (DP) most of participant answer MRI is the best modality for diagnosis of (DP) by percentage (61.5%). Also, statistical significant difference between participants complaining of (DP), risk factors and demographic data P:≤0.05. Conclusions:-most of participant haven't complaining of (DP), have no family history, have good knowledge about risk factors and lack of information about diagnosis and protection from (DP).
Background: Magnetic resonance imaging (MRI) exams may cause patients to feel anxious before or during the scan, which affects the scanning outcome and leads to motion artifacts. Adequate preparation can effectively alleviate patients’ anxiety before the scan. We aimed to assess the effect of different preparation methods on MRI-induced anxiety: We conducted a prospective randomized study on MRI patients between March and May 2022. We divided 30 patients into two groups: the control group, which received routine preparation (RP), and the experimental group, which received video preparation (VP). We used the State-Trait Anxiety Inventory (STAI) to measure anxiety levels before and after the interventions. We assessed patients’ self-satisfaction after the scan: After preparation, VP (STAI mean = 10.7500) and RP (STAI mean = 12.7857), we observed a significant association between the pre- and post-STAI results in VP (p = 0.025). The effects of both methods in decreasing anxiety were more significant for first-timers (p = 0.009 in RP/0.014 in VP). We noted high satisfaction levels for both forms of preparation. The VP technique was superior in reducing patient anxiety, especially in first-time MRI patients. Hence, VP techniques can be used in different clinical settings to reduce anxiety and facilitate patients’ understanding of the instructions given.
Background Artifacts have significantly degraded the quality of computed tomography (CT) images, to the extent of making them unusable for diagnosis. The types of artifact that could be used are as follows: (a) streaking, which is commonly due to a discrepancy in a single measurement, (b) shading, which is due to a group of channels deviating gradually from the true measurement, (c) rings, which are due to errors in individual detector calibration and (d) distortion, which is due to helical reconstruction. It is occasionally possible to avoid scanning of a bony area, by means of changing the postion of the patient. Thus, this study aimed to evaluate the common artifacts that affect image quality and the method of correction to improve image quality. Results The data were collected by distributing a questionnaire to the CT technologist at different hospitals about the most common type of artifacts in the CT images, source of artifacts and methods of correction. A total of 95 CT technologists responded to the questionnaire, which included 67% males and 33% females. Most of the participants (70%) were experienced CT technologists, and 61% of the participants had not done any subspecialty CT scan courses. The most common artifact used in the CT departments was motion artifact in brain CT (73%), and the best method to reduce motion artifact was patient preparation (87%). Conclusions The most common shown artifact in this study was motion artifact, and the common cause was the patient-based artifact. It is important to understand why objects occur and how they could be prevented or suppressed to improve image quality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
