Consistent orientation of the knee in the CT scanner is key for accurate tibial component displacement detection
CT with external loading of the knee can be used for the detection of loosening of the tibial component after total knee arthroplasty (TKA) [1,2], which occurs more frequently than loosening of the femoral component [3]. Compared to conventional radiography — which is known to have limited sensitivity for detecting tibial component loosening [4] (around 70–83 % [5,6]) — load induced CT enables direct assessment of mechanical implant stability rather than relying on indirect markers such as radio…

Personalized adrenal gland volume reference ranges and development of a fully automated deep learning screening tool
Abnormal adrenal gland size is closely associated with various diseases, including primary aldosteronism, Cushing’s syndrome, adrenal tumors, diabetes, cardiovascular diseases, and Hypothalamic Pituitary Adrenal (HPA) axis-related disorders[1–5]. Untimely diagnosis and intervention in primary aldosteronism and Cushing’s syndrome can increase the risk of cardiovascular disease and mortality by 1.5 to 10 times[6–9]. These disorders also significantly increase the risk of metabolic syndrome, partic…

Terminology inconsistencies in LLM-based studies: A caution for radiology
Research on large language models (LLMs) is increasing across various medical specialties, including radiology. New model versions continue to be introduced over time. Accurate reporting of model identity is essential for reproducibility because different versions can vary in capability, training data, and multimodal functionality.

Improving foundation doctors’ knowledge and compliance with the radiology legislation: A quality improvement project
Ionising Radiation (Medical Exposure) Regulations (IR(ME)R) exist to safeguard patients against unnecessary radiation exposure and enhance their involvement in decision-making. However, evidence suggests that resident doctors lack awareness of IR(ME)R. We conducted a quality improvement project to improve Foundation Doctors’ (FDs’) knowledge and compliance with IR(ME)R.

Cardiac magnetic resonance imaging in atrioventricular discordance and congenitally corrected transposition (CCTGA)
CCTGA is characterised by combined atrioventricular (AV) and ventriculoarterial (VA) discordance [1]. Systemic and pulmonary veins typically connect to their appropriate lateralised atria (normal connections). The morphologically right ventricle (mRV) connects to the left atria and an anterior left sided aorta. Consequently, there is a systemic mRV and the tricuspid valve guards the left sided AV junction, while the mitral valve is at the right-sided junction (Fig. 1a). This mirror-imaged ventri…

Imaging biomarkers are key to recognizing fatal breast cancers arising in the major ducts
Regular participation in mammography screening and state of the art treatment of breast cancer at an early phase of its development have resulted in a significant, 40–50 % decrease in breast cancer death in modern screening programs [1–6]. Clinical cancer research faces a new challenge: determining the characteristics of those breast cancers which we are still failing to manage effectively among women who attend screening regularly and receive modern therapeutic regimens. Our approach to this ch…

Integrated assessment of diabetic nephropathy by multi-parametric magnetic resonance imaging with non-enhanced T1 mapping, diffusion tensor imaging, and diffusion kurtosis imaging
Over the past several decades, the number of people with diabetes mellitus (DM) has been rising steadily. As of 2021, the global prevalence of diabetes among individuals aged 20–79 was approximately 10.5 % (about 536.6 million people), and this figure is projected to increase to 12.2 % (about 783.2 million people) by 2045 [1]. Diabetes is the leading cause of chronic kidney disease (CKD), accounting for 30 %–50 % of all CKD cases. The CKD that results from diabetes is clinically known as diabeti…

MR imaging with 15-channel dental coil compared with standard 20-channel coil in patients with head and neck tumours and suspected bone invasion
Head and neck tumours are the sixth most common malignant tumours worldwide and, depending on the topographical relationship, may invade adjacent structures such as the maxilla and mandible [1,2]. Oral cavity and oropharyngeal locations account for half of cases. Treatment depends on the location and size of the primary tumour, the general condition of the patient, the expected treatment-related morbidity with its functional and aesthetic consequences, and the expected success of therapy [3].

Virtual non-calcium imaging to detect bone marrow edema in patients with arthritis: a feasibility study with MRI as standard of reference
To evaluate the diagnostic performance of virtual non-calcium (VNCa) imaging derived from dual-energy CT (DECT) for the detection of bone marrow edema (BME) in patients with suspected hand arthritis using magnetic resonance imaging (MRI) as standard of reference
