A multi-institutional CT practices survey of pediatric head, chest, and abdomen-pelvis examinations Open
Background: Pediatric patients are particularly vulnerable to the stochastic effects of ionizing radiation. Despite these risks, CT remains diagnostically essential in pediatric care. Diagnostic reference levels (DRLs) have been recommende…

Image quality and radiation doses in abdominal CT: A multicenter study Open
There was large variation in radiation dose and image quality across the different CT scanners. Interestingly, the weak correlation between CTDIvol and CNR indicates that higher doses do not consistently improve CNR, indicating a need for …

Evaluation of an in-use chest CT protocol in lung cancer screening - A single institutional study Open
Background Lung cancer is the most common cause of cancer-related death worldwide and therefore there has been a growing demand for low-dose computed tomography (LDCT) protocols. Purpose To investigate and evaluate the dose and image quali…

Research activity among diagnostic and therapeutic radiographers: An international survey Open
A minor segment of survey respondents indicated involvement in research activity. Lack of dedicated time to research, mentors, and funding were among the main barriers to conduct research. Further research is required to explore what solut…

Metal artifact reduction on musculoskeletal CT: a phantom and clinical study Open
Background Artifacts caused by metal implants are challenging when undertaking computed tomography (CT). Dedicated algorithms have shown promising results although with limitations. Tin filtration (Sn) in combination with high tube voltage…

A survey of local diagnostic reference levels for the head, thorax, abdomen and pelvis computed tomography in Norway and Canada Open
Background Computed tomography (CT) contributes to 60% of the collective dose in medical imaging. Literature has demonstrated that patient dose varies across regions and countries. Establishing diagnostic reference levels (DRLs) contribute…

A survey to explore the psychological impact of the COVID‐19 pandemic on radiation therapists in Norway and Canada: A tale of two countries Open
Introduction Several studies have demonstrated the psychological impact of the COVID‐19 pandemic on health care providers. However, there is little known about how the COVID‐19 pandemic has impacted radiation therapists (RTs) in Norway or …

Overall survival after initial radiotherapy for brain metastases; a population based study of 2140 patients with non-small cell lung cancer Open
Overall survival after radiotherapy (RT) for BM improved during the study period, but only for patients treated with SRT. Survival after WBRT remains poor; its use should be questioned. DS-GPA and Lung-molGPA seem most useful in predicting…

Contrast medium protocols in routine chest CT: a survey study Open
Background Administration of contrast medium (CM) is an important image quality factor in computed tomography (CT) of the chest. There is no clear evidence or guidelines on CM strategies for chest CT, thus a consensus approach is needed. P…

Use of radiotherapy in breast cancer patients with brain metastases: a retrospective 11-year single center study Open
WBRT was the most frequent primary RT. An increased use of initial SRS was observed in the second half of the study period. Only ECOG 0 and brain metastasis surgery were associated with superior OS in multivariate analysis.

Overall survival after initial radiotherapy for brain metastases; a population based study of 2140 patients with non-small cell lung cancer Open
Brain metastases (BM) occur in about 30% of all patients with non-small cell lung cancer (NSCLC). BM treatment guidelines recommend more frequent use of stereotactic radiotherapy (SRT). Overall, studies report no difference in overall surv…
