Assessment of the professional practice knowledge of computed tomography preceptors

Investigation of radiology professionals' awareness of CT head artifacts

OBJECTIVE

Computerized tomography (CT) artifacts can happen for various causes. It is critical to understand these artifacts because they can mimic disease or reduce image quality to non-diagnostic levels. CT artifacts can be characterized according to their underlying cause. This study aims to evaluate and compare the understanding of CT head artifacts between radiographers and radiography interns, supplemented by insights from a select group of participating radiologists.

RESULTS

A cross-sectional survey study included 150 participants. All participants' average knowledge score of CT head artifact was good (77.81%). The most correctly identified CT head artifacts were the metal artifact (86%), ring artifact (84.7%), and motion artifact (81.3%). The beam hardening artifact was correctly identified less frequently (62%). There is significant difference in the recognition of motion artifacts among the participants (P = 0.001) knowledge of CT head image artifacts improved significantly with more experienced participants (P = 0.001), where participants with less than 10 months of experience had a higher rate of incorrect responses (85 incorrect vs. 31 correct). The recognition of these artifacts improves with experience and advanced age. Understanding these artifacts is essential to avoid misdiagnosis of various diseases.

The scope of practice for diagnostic radiographers in Singapore: A preliminary survey

INTRODUCTION

There has been an increased demand for medical imaging procedures through the years. This demand requires the diagnostic radiographers in the workforce to be equipped with adequate training and understanding of their roles. The aims of this research are to distill and further describe the current scope of practice as established by the Allied Health Professional Council and map the diffusion of tasks, roles and responsibilities within Singapore's radiography imaging modalities.

METHODS

A structured questionnaire was distributed to all diagnostic radiographers in Singapore through emails sent out by the Singapore Society of Radiographers. Information collected included respondents' duties in their respective imaging modalities, the professional tracks they specialised in, and their demographical information. Quantitative data analysis was conducted using SPSS and Fisher's Exact test of independence was used to determine correlations between variables.

RESULTS

A total of 120 questionnaire responses were obtained and after exclusion, 99 responses were analysed. It was observed that there was a significant positive correlation in radiography experience and performing specialised Computed Tomography examinations (p = 0.005). Additionally, higher radiographer designation was shown to be correlated with the ability to perform more specialised Ultrasound examinations (p < 0.001). The study demonstrated a diverse range of tasks by radiographers which was determined by education, disparity in experience, institutional practice and training provided.

CONCLUSION

This preliminary study on Singapore diagnostic radiographers provided valuable insight and mapping of their activities in several imaging modalities, allowing for future development of a scope of practice document for Singapore.

IMPLICATION FOR PRACTICE

The tasks undertaken by the diagnostic radiographers were integral to imaging service delivery and play a significant role in the advancement of radiography to further enhance the quality of patient care.

Latiff R, Mohamad M. Investigating knowledge of DRLs, image quality and radiation dose in PET/CT and CT imaging among medical imaging professionals

Objective

To investigate the knowledge of diagnostic reference levels (DRLs), image quality, radiation dose and protocol parameters among Jordanian medical imaging professionals (MIPs) involved in PET/CT and CT scan procedures.

Materials and methods

A questionnaire was designed and distributed to MIPs in Jordan. The survey comprised four sections: demographic data, MIP knowledge on dose/protocol parameters, image quality, and DRLs. Statistical analyses were performed utilizing Pearson's correlation, t-tests, ANOVA, and linear regression, with a significance level of 95 % and a p-value threshold of <0.05.

Results

The study involved 147 participants. Most respondents were male (76.2 %), and most were aged 26-35 years (44.2 %). Approximately 51 % held a bachelor's degree, and the most common range of experience was 3-5 years (28.6 %). Participants showed a moderate level of knowledge regarding dose and protocol parameters, with a mean score of 61.8 %. The mean scores for knowledge of image quality and DRLs were 45.2 % and 44.8 %, respectively. The age group of the MIPs and the total experience were found to have a significant impact on the knowledge of the dose and protocol parameters, as well as the DRLs. Additionally, experience was found to have a significant influence on knowledge of the dose and protocol parameters. The study revealed a positive and significant effect of MIPs' knowledge of dose/protocol parameters and image quality on their knowledge of DRLs.

Conclusions

This study indicates that professionals across five specialties who are engaged in PET/CT and CT imaging possess a moderate understanding of dosage and protocol parameters. However, there is a notable gap in knowledge regarding DRLs and image quality. To address this issue, it is recommended that MIPs actively engage in educational programs emphasizing exposure parameters and their impact on image quality. Additionally, access to comprehensive education and training programs will enable MIPs to grasp the complexities of DRLs and their implications, facilitating their implementation in clinical practice.

Assessing the knowledge of CT radiographers regarding how CT parameters affect patient dose and image quality

PURPOSE

The objective of this study was to assess the current knowledge of CT radiographers regarding the optimization of CT parameters and their consequential effects on both patient dose and image quality.

METHOD

A nationwide, cross sectional study was conducted from the 2nd of January 2023 to 1st of March 2023 to evaluate CT radiographers' knowledge in managing CT parameters in Jordan. Recruitment involved convenience sampling where radiographers were invited to participate and complete the questionnaire. Descriptive statistics were used to report the normalized knowledge scores. Student's t-test and ANOVA were used to investigate and compare the outcomes between different subgroups. A forward stepwise linear regression was used to investigate the influence of a number of technologist related factors on the knowledge score.

RESULTS

Three hundred and fifty-seven radiographers participated in the study, with a mean knowledge score of 69.0%. Participants with an academic master's degree had a significantly higher score of 72.1% compared to the ones with a diploma degree, with a score of 66.8% (p = 0.026). No statistically significant difference was found between radiographers that received additional training and the ones that did not. Furthermore, when investigating the effects of academic education, working sector, additional training and years of experience, only education had a statistically significant impact on the knowledge score.

CONCLUSION

The results demonstrate that radiographers have an overall good understanding of CT parameters, with academic education having a significant influence on their performance.

AWARENESS OF PAEDIATRIC RADIOLOGICAL PROTECTION AND IMAGING PARAMETERS AMONG GROUP OF SRI LANKAN RADIOGRAPHERS

The present survey evaluated the level of awareness of radiological protection concepts and imaging parameters among Sri Lankan radiographers for the first time. The data were collected using an electronic questionnaire of 22 questions on demographic data, awareness of radiation protection concepts and imaging parameters. Only 84 out of 122 (68.8%) requested radiographers to return the questionnaire. More than 85% had ≥3 years of experience in the radiography field. The average scores for questions on best practices, imaging parameters and radiation protection were 75, 75.8 and 70.2%, respectively, with an overall score of 73.4%. Significant confusion existed on protective shielding, paediatric consenting capability, use of grids and excess X-ray field during paediatric radiography. Although the overall knowledge and awareness of participants on studied concepts were satisfactory, a continuous professional development credit system and implementation of a code of practice are required to improve the quality of radiography practice.

The radiology workforce's response to the COVID-19 pandemic in the Middle East, North Africa and India

INTRODUCTION

This study aimed to investigate the response of the radiology workforce to the impact of the coronavirus disease 2019 (COVID-19) pandemic on professional practice in India and eight other Middle Eastern and North African countries. It further investigated the levels of fear and anxiety among this workforce during the pandemic.

METHODS

A quantitative cross-sectional study was conducted using an online survey from 22 May-2 June 2020 among radiology workers employed during the COVID-19 pandemic. The survey collected information related to the following themes: (1) demographic characteristics, (2) the impact of COVID-19 on radiology practice, and (3) fear and (4) anxiety emanating from the global pandemic.

RESULTS

We received 903 responses. Fifty-eight percent had completed training on infection control required for handling COVID-19 patients. A large proportion (79.5%) of the respondents strongly agreed or agreed that personal protective equipment (PPE) was adequately available at work during the pandemic. The respondents reported experiences of work-related stress (42.9%), high COVID-19 fear score (83.3%) and anxiety (10%) during the study period.

CONCLUSION

There was a perceived workload increase in general x-ray and Computed Tomography imaging procedures because they were the key modalities for the initial and follow-up investigations of COVID-19. However, there was adequate availability of PPE during the study period. Most radiology workers were afraid of being infected with the virus. Fear was predominant among workers younger than 30 years of age and also in temporary staff. Anxiety occurred completely independent of gender, age, experience, country, place of work, and work status.

IMPLICATIONS FOR PRACTICE

It is important to provide training and regular mental health support and evaluations for healthcare professionals, including radiology workers, during similar future pandemics.

Computed tomography radiation doses for common computed tomography examinations: a nationwide dose survey in United Arab Emirates

OBJECTIVES

Computed tomography (CT) scanning is an essential part of diagnostic and treatment plans, providing swift and accurate diagnostic images. The aim of this study is to develop diagnostic reference levels (DRLs) for the adult common CT examination in the United Arab Emirates (UAE).

METHODS

This study presents results of the survey of CT dose indices. The data were collected from 91% of the scanners registered at the Ministry of Health and Prevention (MOHAP) for five common examinations: head, chest, and abdomen-pelvis with and without CM.

RESULTS

CT dose index, dose-length product, and patient weight were analyzed; the reference dose was calculated on the 75th percentile, and an achievable dose was proposed from the median value. The results were compared with the UAE initial National Dose Report as well as the international reports. The proposed dose for CTDI_vol (mGy) and DLP (mGy cm) is as follows: head without CM 40 and 695, head with CM 48 and 820, chest 10 and 275, abdomen-pelvis without CM 14 and 810, and abdomen-pelvis with CM 20 and 1025.

CONCLUSIONS

The results show low dose variations between the MOHAP scanners. The data also revealed CTDI_vol and DLP values comparable to those in the initial NDRL report and international standards. The establishment of diagnostic reference levels will require a continuous dose monitoring system.
