The impact of body composition abnormalities and clinical outcomes in patients with cirrhosis is well established. Abdominal computed tomography (CT) evaluation is the technique that is better evaluated; however, agreements are not well known. Fifty patients were randomly selected from two centers, and two observers independently evaluated their CT. The cross-sectional muscle area (CSMA), skeletal muscle index (SMI), muscle attenuation (MA), visceral adipose tissue area (VAT), visceral adipose t…

Development and characterization of new contrast agents for Photon-Counting CT
The visualization and characterization of benign and malignant structures using computed tomography (CT) is an integral part of clinical routine and thus, CT is one of the most important non-invasive imaging modalities available today [1–4]. The number of CT scans performed each year is approximately 300 million with an annual growth rate of 4 % [1]. A disadvantage of the current CT imaging technology, however, is the detection of the X-rays, which is conventionally performed using energy-integr…

Hitting the Bull’s AI: artificial Intelligence-derived imaging features and their association with outcomes in CT-guided lung biopsy, a retrospective study
The role of artificial intelligence in medical imaging has become increasingly prevalent over the past years. Numerous applications have already appeared on the market, starting with analyzing conventional imaging like chest radiographs, but lately also encompassing cross-sectional modalities such as computed tomography (CT) or magnetic resonance imaging. Recent advances have paved the way for an automatic characterization of radiographic patterns in medical imaging data [1], which may enhance t…

Ccta-based AI for Diagnosing ≥ 50 % coronary Stenosis: A patient- and Vessel-Level meta-analysis
A summary statement: With the continuous advancement of AI technology, it has been widely applied in cardiovascular imaging. However, robust evidence regarding AI’s diagnostic efficacy of 50 % coronary stenosis remains limited. Our meta-analysis synthesizing studies on CCTA-based AI systems for diagnosing ≥ 50 % coronary stenosis revealed consistently high AUC and sensitivity at both patient and vessel levels, confirming AI’s substantial diagnostic capability for ≥ 50 % coronary stenosis, while …

Evaluation of Age-Related compositional changes in the infrapatellar fat pad using MRI-Derived PDFF and T2* at 1.5 T
To investigate age-related compositional changes in the infrapatellar fat pad (IFP) using chemical shift-encoded MRI-derived proton density fat fraction (PDFF) and T2* at 1.5 T, and to evaluate their associations with clinical symptoms and structural abnormalities.

Contrast enhanced ultrasound at first month: A feasible predictor for retreatment after benign thyroid nodule thermal ablation
Benign thyroid nodules (BTNs) are a common occurrence in the population [1]. The estimated prevalence of thyroid nodules in global is as high as 67 %, with nearly 90 % characterized as benign [2]. Clinical interventions typically deemed unnecessary in the majority of BTNs. However, palpable large BTNs necessitate treatment due to nodule-related compressive symptoms or cosmetic concerns [3]. Ultrasound (US)-guided thermal ablation (TA), encompassing modalities such as radiofrequency ablation (RFA…
