To evaluate the diagnostic performance of Angio-based fractional flow (Angio-FF) compared to the degree of stenosis (DS) in identifying symptomatic intracranial vertebrobasilar artery stenosis (IVBS) and assess its utility across lesion subgroups.

Arterial transit artefacts (ATAs) on pseudo-continuous arterial spin labelling (pCASL) MRI represent visual markers of delayed arterial transit. This study aimed to investigate their prevalence and distribution and to evaluate the effects of sex, ethnicity, intracranial arterial anatomy, and cardiovascular parameters in a subgroup of the UK tri-ethnic population-based Southall and Brent REvisited (SABRE) study.

Renal pathology is common in childhood. Imaging plays a critical role in the diagnosis of kidney diseases and encompasses a range of modalities. Advanced imaging is typically performed in specialised paediatric hospitals, where experienced paediatric radiologists are familiar with the relevant techniques, protocols, indications, and limitations. However, children are often first admitted to general hospitals, where radiologists may have more limited experience in paediatric imaging. Renal cysts in children differ from those in adults, most commonly presenting as cystic kidney diseases. In the majority of cases, ultrasound (US) is the sole diagnostic modality required. Imaging is not necessary for the diagnosis of urinary tract infection (UTI), but it is essential for detecting underlying anomalies and potential complications. Urinary tract dilatation is a common finding in children; however, only up to 30% of cases require further evaluation to diagnose urinary tract obstruction or vesicourinary reflux. Urolithiasis is relatively uncommon in children and is primarily diagnosed with US, although computed tomography (CT) may occasionally be necessary. Solid renal lesions identified on US should be further evaluated in highly specialised paediatric centres. Mild to moderate renal trauma can be diagnosed and monitored using US, whereas CT remains the modality of choice for assessing severe trauma. CLINICAL RELEVANCE STATEMENT: This review provides general radiologists with a comprehensive overview of the normal renal appearance across paediatric age groups, including normal variants and imaging pathways for the most common renal pathologies in children. It also highlights scenarios where referral to specialised paediatric centres is necessary. KEY POINTS: US is the first-line imaging modality for diagnosing most renal pathologies in children. MRI is used in a variety of situations (e.g. complex congenital anomalies of the kidney and urinary tract, or focal lesions) when US is not sufficient. CT is reserved for emergencies and in selected cases of urolithiasis. Knowledge of normal renal features, including normal anatomical and morphological variants across different age groups, is essential.

Using a large elderly population cohort, we investigated the relationship between choroid plexus (CP) volume, a potential indicator of glymphatic system activity, and lifestyle-related vascular risk and protective factors, as well as age-related changes in CP volume.

The study aimed to evaluate the utility of 3D transrectal ultrasonography (3D-TRUS) for perianal Crohn's disease (pCD) activity stratification.

To develop and externally validate a computed tomography (CT)-based multitask learning model to predict fracture risk.

To assess the prognostic value of tumor-stroma ratio (TSR) in intrahepatic mass-forming cholangiocarcinoma (IMCC) and its subtypes, and to explore the correlation between gadoxetic acid-enhanced MRI and TSR.

Trigeminal neuralgia (TN) is a severe pain disorder for which MRI helps to identify the anatomical causes of pain. However, imaging protocols vary widely, and a plethora of imaging features that might contribute to different forms of TN have been described. This review aims to (1) summarize current evidence on MRI techniques and their diagnostic performance, and (2) evaluate imaging markers that improve our understanding of TN pathophysiology and support clinical decision-making regarding surgical or interventional treatment.

To determine whether routine prostate MRI can quantify atrophy and fatty infiltration of the obturator internus (OI) muscle in prostate cancer (PCa) patients undergoing androgen deprivation therapy (ADT), to explore concordance between MRI-derived OI metrics and CT-based body composition, and evaluate their impact on progression-free survival (PFS).

To evaluate the diagnostic value of a multi-parametric MRI model integrating functional (DWI/DCE) and morphological (T2WI) biomarkers for differentiating T2-stage from T3a-b-stage rectal lesions.

To compare the operational efficiency, including performance, contrast media (CM) utilization, and technologist satisfaction between a multi-use syringeless power injector (MU-SPI) and a conventional single-use dual-syringe power injector (SU-DSPI).

Atherosclerotic carotid artery disease (CarAD) is a significant contributor to the global burden of cerebrovascular diseases. Several positron emission tomography computed tomography (PET/CT) radiotracers showed promising results in identifying and assessing vulnerable carotid atherosclerotic plaque. This review aims to assess the current evidence surrounding the use and potential of multiple PET radiotracers in identifying vulnerable carotid atherosclerotic plaque.

The diagnosis of inferior alveolar nerve (IAN) and lingual nerve (LN) injuries currently relies on imaging and clinical examinations. Magnetic resonance neurography (MRN) demonstrates limited sensitivity in mild-to-moderate IAN and LN injuries, while quantifiable parameters correlating with symptomatology and prognostic outcomes remain undefined.
