Artificial intelligence (AI) is increasingly utilised in medical imaging systems and processes, radiographers must embrace this advancement. This study aimed to investigate perceptions, knowledge, expectations towards integrating AI into amongst a sample of determine the current state education within community.A cross-sectional online quantitative targeting based Europe was conducted over ten weeks. Captured data included demographical information, participants' perceptions understanding...
Purpose To develop low-dose thin-section computed tomographic (CT) protocols for assessment of cystic fibrosis (CF) in pediatric patients and determine the clinical usefulness thereof compared with chest radiography. Materials Methods After institutional review board approval informed consent from or guardians were obtained, 14 CF 11 without (16 male, nine female; mean age, 12.6 years ± 5.4 [standard deviation]; range, 3.5–25 years) who underwent imaging reasons CT. Sections 1 mm thick...
The size-specific dose estimate (SSDE) is a dose-related metrics that incorporates patient size into its calculation. It usually derived from the volume computed tomography index (CTDIvol) by applying conversion factor determined manually measured anteroposterior and lateral skin-to-skin diameters at midslice level on (CT) localiser images, an awkward, time-consuming, not highly reproducible technique. objective of this study was to evaluate potential for use body mass (BMI) as size-related...
According to current literature, there is a lack of information regarding the radiation protection (RP) practices interventional radiology (IR) and cardiology catheter laboratory (CCL) staff. This study aims determine RP staff within IR CCLs internationally suggest areas for improvement.
Computed tomography (CT) helps physicians locate and diagnose pathological conditions. In some conditions, having an airway segmentation method which facilitates reconstruction of the from chest CT images can help hugely in assessment lung diseases. Many efforts have been made to develop algorithms, but methods are usually not optimized be reliable across different scan parameters. this paper, we present a simple semi-automatic algorithm segment tracheal bronchial anatomy using open-source...
Cardiac computed tomography angiography (CCTA) is essential for diagnosing coronary artery disease, with accurate positioning critical optimising image quality (IQ) and radiation exposure. Vertical misalignment can degrade IQ increase dose. Automatic 3D camera systems claim to improve accuracy reduce errors, though research on their effectiveness in CCTA remains limited. This study evaluates accuracy, dose, when using automatic across scenarios. prospective phantom utilised the Multipurpose...
We designed a prospective study to investigate the in-vivo relationship between abdominal body composition and radiation exposure determine strongest predictor of dose length product (DLP) at CT.Following institutional review board approval, quantitative analysis was performed prospectively on 239 consecutive patients who underwent abdominopelvic CT. DLP, BMI, volumes adipose tissue, muscle, bone solid organs were recorded.All measured parameters correlated positively with DLP. Linear...

•CF may be evaluated with CT at a radiation dose equivalent to chest radiograph.•Low thoracic acquired mean ED of 0.08 ± 0.01mSv.•Compared ASIR, MBIR images demonstrate superior objective image parameters. AIMTo assess the utility volumetric low-dose computed tomography (CT) thorax (LDCTT) protocol posteroanterior (PA) and lateral radiograph for surveillance cystic fibrosis (CF) patients.MATERIALS AND METHODSA prospective study was undertaken 19 adult patients CF that proceeded LDCTT 12 24...
Dementia is a syndrome associated with decline in brain function, impacting how we speak, think, feel, and behave. Misunderstanding of dementia it affects patients their carers common. There limited research on radiographers provide adequate care to those dementia. Radiographers knowledge positive attitudes can reduce stigma fear, improving the quality care. This study aimed assess radiographers' towards dementia.A cohort registered Ireland participated an online survey. Two pre-existing...
Despite limitations of routine methods, Clinical Practice Guidelines support the assessment bone mineral density (BMD) and vascular calcification in renal transplant recipients. Changes fat mass also occur post-transplantation, although they are traditionally difficult to measure accurately. We report feasibility, convenience accuracy measuring above 3 parameters using a novel CT protocol. conducted cross-sectional study 64 first allograft recipients (eGFR > 30 ml/min/1.73 m2). Quantitative...
IntroductionThis study investigates instances of elevated radiation dose on a tracking system to determine their aetiologies. It aimed investigate the impact radiographer feedback these alerts.MethodsOver two six-month periods 11,298 CT examinations were assessed using DoseWatch. Red alerts (dose length products twice median) identified and independent reviewers established whether true (unjustifiable) or false (justifiable). During second time period radiographers used tool state cause...
BACKGROUND Incidental pulmonary nodules are an increasingly common finding on computed tomography (CT) scans of the thorax due to exponential rise in CT examinations everyday practice. The majority incidental benign and correctly identifying small number malignant is challenging. Ultra-low-dose (ULDCT) has been shown be effective diagnosis respiratory pathology comparison with traditional standard dose techniques. Our hypothesis was that ULDCT chest combined model-based iterative...
We have observed a distinct clinical syndrome amongst acutely unwell children frequently associated with the administration of traditional medicine enema. describe clinicopathological features this 'enema syndrome' based on retrospective case note review 50 consecutive admissions to South African rural district hospital. Admission was prompted by sudden, marked deterioration following enema (68% seen within 24 h). Respiratory distress tachypnoea, abdominal distension, hypotonia and loss...
Within the Porcupine Bank Canyon (NE Atlantic), cold-water coral (CWC) mounds are mostly found clustered along canyon lip, with individual disconnected occurring nearby on western Bank. Remotely operated vehicle-mounted vibrocoring was utilized to acquire cores from both of these sites. This study is first employ this novel method when aiming precisely sample two closely situated areas. Radiometric ages constrain records early mid-Holocene (9.1 5.6 ka BP). The were then subjected 3D...
