Abstract:Introduction: Chest radiology is pivotal managing acute COVID-19 illness but potentially equally important to follow up. Objectives of this study were to (1) quantify those with COVID requiring follow up, (2) investigate how findings relate to severity, and (3) report abnormal radiology at follow up estimating continued demands.
Methods: Retrospective analysis of 217 patients, mean age 71.8 (SD 8.7, range 29-87) years, admitted March to May 2020 and subsequently tracked. Patients requiring >40% FiO2, and/or respiratory device support had severe disease and CXRs were normal or abnormal to COVID changes. Data analysed using statistical software reporting comparisons by chi square (X2).
Results: Initial CXRs for 123/213 (58%) patients were abnormal; 59/153 (39%) surviving admission attended follow up; others defaulted or were not requested with normal CXR or expected poor prognosis. 39 (66%) CXRs improved, 20 (34%) remained abnormal; of these, 9 patients had chest CT scans. Severe disease contributed to higher mortality, respectively 37/58 (64%) versus 46/159 (29%), X2 (df 1, n=217) 21.87, p=.0001. Comparing abnormal with normal CXR, 47/122 (39%) versus 11/91 (12%) had severe disease, X2 (df 1, n=213) 18.38, p=.000018. 55/123 (45%) versus 28/90 (31%) of those with initial abnormal CXR have since died, X2 (df 1, n=213) 4.04, p=.0044.
Conclusions: Mortality is associated with both the severity of illness and initial COVID related abnormal CXR; 58% have such changes at presentation and among the survivors having follow up radiology improves in two-thirds with approximately half the others then investigated by chest CT giving some indication to planning future services.

Abstract:Background: Combined Lung Ultrasound (LUS) and Focused UltraSound for Intensive Care heart (FUSIC Heart – formerly Focused Intensive Care Echocardiography, FICE) can aid diagnosis, risk stratification and management in COVID-19. However, data on its application and results are limited to small studies in varying countries and hospitals. This United Kingdom (UK) national service evaluation study assessed how combined LUS and FUSIC Heart were used in COVID-19 Intensive Care Unit (ICU) patients during the first wave of the pandemic. Method(s): Twelve trusts across the UK registered for this prospective study. LUS and FUSIC Heart data were obtained, using a standardised data set including scoring of abnormalities, between 1st February 2020 to 30th July 2020. The scans were performed by intensivists with FUSIC Lung and Heart competency as a minimum standard. Data was anonymised locally prior to transfer to a central database. Result(s): 372 studies were performed on 265 patients. There was a small but significant relationship between LUS score >8 and 30-day mortality (OR 1.8). Progression of score was associated with an increase in 30-day mortality (OR 1.2). 30-day mortality was increased in patients with right ventricular (RV) dysfunction (49.4% vs 29.2%). Severity of LUS score correlated with RV dysfunction (p < 0.05). Change in management occurred in 65% of patients following a combined scan. Conclusion(s): In COVID-19 patients, there is an association between lung ultrasound score severity, RV dysfunction and mortality identifiable by combined LUS and FUSIC Heart. The use of 12-point LUS scanning resulted in similar risk score to 6-point imaging in the majority of cases. Our findings suggest that serial combined LUS and FUSIC Heart on COVID-19 ICU patients may aid in clinical decision making and prognostication.

Abstract:PURPOSE Traditional undergraduate radiographer training mixes academic lectures and clinical practice. Our goal is to bridge the current disconnection between theory and practice in a safe environment, avoiding the risk of radiation for both practitioners and patients. To this end, this research proposes a new software to teach diagnostic radiography using real-time interactive X-ray simulation and patient positioning. METHODS The proposed medical simulator is composed of three main modules. A fast and accurate character animation technique is in charge of simulating the patient positioning phase and adapts their internal anatomy accordingly. gVirtualXRay is an open-source X-ray simulation library and generates the corresponding radiographs in real time. Finally, the courseware allows going through all the diagnostic radiology steps from the patient positioning and the machine configuration to the final image enhancing. RESULTS A face and content validation study has been conducted; 18 radiology professionals were recruited to evaluate our software using a questionnaire. The results show that our tool is realistic in many ways (72% of the participants agreed that the simulations are visually realistic), useful (67%) and suitable (78%) for teaching X-ray radiography. CONCLUSIONS The proposed tool allows simulating the most relevant steps of the projectional radiography procedure. The virtual patient posing system and X-ray simulation module execute at interactive rates. These features enable the lectures to show their students the results of good and bad practices in a classroom environment, avoiding radiation risk.

Abstract:
Introduction: Radiologists utilise mammography test sets to bench mark their performance against recognised standards. Using a validated test set, this study compares the performance of radiographer readers against previous test results for radiologists. Method(s): Under similar test conditions radiographer readers were given an established test set of 60 mammograms and tasked to identify breast cancer, they were measured against their ability to identify, locate and give a confidence level for cancer being present on a standard set of mammographic images. The results were then compared to previously published results for radiologists for similar or the same test sets. Result(s): The 10 radiographer readers demonstrated similar results to radiologists and for lesion sensitivity were the highest scoring group. The study group score a sensitivity of 83; a specificity of 69.3 and lesion sensitivity of 74.8 with ROC and JAFROC scores of 0.86 and 0.74 respectively. Conclusion(s): Under test conditions radiographers are able to identify and accurately locate breast cancer in a range of complex mammographic backgrounds. Implications for practice: The study was performed under experimental conditions with results comparable to breast radiologists under similar conditions, translation of these findings into clinical practice will help address access and capacity issues in the timely identification and diagnosis of breast cancer.

Abstract:
Aim: Radiographs for the assessment of femoral neck fractures are frequently inadequate for the visualisation of the proximal femur. A low centred radiograph of both hips offers enough information but is rarely achieved.We sought to determine the proportion of hip fractures where initial radiographs adequately visualised the femur to encompass the proposed surgical management.We also sought to find the proportion of patients who required repeat radiographs and whether this was affected by time of presentation. Method(s): A retrospective review of the radiographs of hip fractures presenting to our institution, over a three-month period was undertaken. The timings, number and adequacy of radiographs was assessed. Result(s): Radiographs of 89 patients were reviewed. Most radiographs were taken between 8am and 5pm. Radiographs of 58 patients were centred on the pelvis rather than the hips. Patients presenting overnight were more likely to have adequate radiographs. Despite a duplicate x-ray rate of 48%, most patients (55%) had inadequate visualisation of the proximal femur. The average excess radiation exposure by duplicate radiographs was 2.31mSv per patient. Conclusion(s): The majority of patients had inadequate visualisation of the fractured proximal femur on their radiographs.Many had excessive radiographs performed. This was not improved by increased staffing levels during daylight hours.

Abstract:
Introduction: A voluntary accreditation scheme has been introduced, requiring advanced (AdP) and consultant practitioners (CP) to submit several pieces of work to the College of Radiographers (CoR). However, few individuals have opted to become voluntary accredited. This study investigated the reasons behind becoming voluntary accredited, the value that was gained and why there appears to be a lack of support for the scheme.
Method(s): An online electronic survey was conducted using a mixed methods approach. Open questions enabled individual opinions and thoughts to be expressed, Likert scale style questions allowed further understanding of the level of agreement and closed questions identified the support for and against the scheme.
Result(s): A total of 55 respondents participated, including 18 AdPs, 25 CPs, 1 consultant trainee practitioner, 5 practitioners and 6 listed as 'other'. Forty-four participants were non-accredited, citing too much clinical work; no recognition from employers and too much effort for little reward. Motivations for joining the scheme were to improve the profession; help create a new consultant post and protect the non-clinical element of the consultant role.
Conclusion(s): The CoR voluntary accreditation scheme has a small perceived value but overall, the majority of respondents believed the scheme did not warrant the work needed to apply. Concern was raised about the risk of creating a two-tier profession by the scheme's instigation. The results of this study suggest that the CoR's voluntary accreditation scheme would need to address these barriers before more practitioners would apply.

Abstract:
Introduction & Objective: Men with abnormal digital rectal examination or raised PSA usually undergo
transrectal ultrasound (TRUS) prostate biopsies. NICE guidelines do not recommend routine MRI prostate before prostate biopsy unless they have a previous negative prostate biopsy. However, all men with positive prostate biopsies will have MRI prostates. The recent publication of PROMIS (Prostate MR Imaging Study) trial suggests that MRI prostate can reduce unnecessary biopsies by a quarter and can improve detection of clinically significant cancer. In light of this, we would like to determine if performing MRI prostate before biopsy is likely to increase workload in our radiology department in a district general hospital in the UK. Materials and Methods: Patients who underwent TRUS prostate biopsy between 3 Dec 2015 to 28 April 2016 were identified. Their data were analysed retrospectively. 1 year follow-up was chosen to see how many patients would have had MRIs. Results: 173 patients were listed for prostate biopsies but only 158 patients had biopsies with an average age of 69.8 years old (range: 49-88 years old) and an average PSA of 48.1ug/l (range: 0.5-3283.1ug/l). 57 patients had a negative prostate biopsy during this period. 30/57 patients did not have a MRI at all; 12/57 patients had a MRI after biopsy; 1/57 patient had a MRI as an acute setting after biopsy to look for abscesses; and 14/57 patients had a MRI before biopsy. Conclusions: In our study, 30/158 (19.0%) did not have any MRI prostate in 1 year after their first prostate biopsy. However, it is possible that this group of patients will have a MRI prostate in the second year or later. If we were to perform a MRI prostate before TRUS prostate biopsy for all patients, it would increase 19.0% workload for our radiology department.

Abstract:
Objective: The UK radiotherapy (RT) workforce needs novel strategies to manage increasing demand. The appointment of a palliative RT (PRT) consultant radiographer (CR) offers a potential solution to enhance patient pathways providing timely RT. This article examined the impact of one such appointment. Methods: Two prospective audits were completed 1 year apart. All patients receiving PRT for bone metastases between 01/01/2014-31/03/2014 (Audit 1) and 01/01/2015-31/01/2015 (Audit 2) were included. Data collected included demographics, treatment site, dose, fractionation, treatment indication and professionals who planned the PRT. The patient pathway from decision to treat (DTT) to commencement of PRT was scrutinized. Results: 97 patients were identified for Audit 1 and 87 patients for Audit 2. Demographics were similar. Figures relate to Audit 1 and in brackets Audit 2. Indications for treatment: pain 55% (61%), metastatic spinal cord compression 41% (38%) and other neurological symptoms 4% (1%). The CR independently planned 13% (60%), being supervised for 36% (3%). Consultant clinical oncologists planned 43% (31%), with 7% (6%) planned by specialist registrars (SpRs). The pathway was enhanced in Audit 2, with 85% of patients treated within 14 days compared with 73% of patients treated in Audit 1. Conclusion: A CR has the potential to impact on the patient pathway, enabling quicker times from DTT to treatment. Continued audit of the role is required to ensure that it complements SpR training. Advances in knowledge: Increasing longevity and improved systemic therapies have led to greater numbers of patients living longer with metastatic disease. The appointment of a CR offers a potential solution to the capacity difficulties faced by UK RT services.
