The purpose of this article is to evaluate the role of contrast-enhanced ultrasound in the characterization of non-traumatic focal splenic lesions.
Focal splenic lesions are less common than in other abdominal organs like the liver. Conventional ultrasound and Doppler ultrasound have a limited role in the characterization of splenic lesions, resulting in many of them unspecified.
Contrast ultrasound is an accessible, cheap, and safe technique which can help in the immediate characterization of lesions incidentally detected in the ultrasound examination, being a good alternative to others imaging techniques.
We review in detail the technique and the main indications. We also analyze imaging findings and enhancement pattern by using representative case of the main splenic lesions for both benign (epithelial cyst, cystic lymphangioma, hemangioma, hamartoma, infarction, sclerosing angiomatous nodular transformation, abscesses, sarcoidosis), and malignant (lymphoma, metastasis) and its pathological correlation in some cases.

Background and objective
Atrial fibrillation (AF) is the most common cardiac arrhythmia worldwide. Previous studies have described that certain clinical characteristics such as age, obesity, the type of AF, and imaging-based factors, such as left atrial (LA) volume, mean density (calculated as the average of Hounsfield Units values in a certain region of interest), and volume of cardiac adipose tissue, may increase the risk of recurrence following pulmonary vein ablation. However, there have been contradictory results regarding radiological variables in previous studies. The objective of this study was to evaluate these clinical and radiological risk factors obtained from computed tomography (CT) studies.
Materials and methods
This retrospective case-control study included all patients with AF who underwent initial radiofrequency or cryoablation of pulmonary veins after undergoing contrast-enhanced CT between 2017 and 2021. Clinical variables such as age, gender, comorbidities, medications used after ablation, type of AF, and radiological variables obtained from volumetric segmentation of CT studies were collected. Radiological variables included LA volume, mean density, and volume of epicardial, periatrial, and interatrial adipose tissue. The occurrence or absence of AF recurrence within 12 months after ablation was also recorded. These variables were subjected to univariate and multivariate analysis to evaluate the risk of recurrence.
Results
Among the total number of included patients, 40 had paroxysmal AF and 12 had persistent AF. During the follow-up period, 12 patients (23.1%) experienced AF recurrence, while 40 patients (76.9%) remained in sinus rhythm. There were statistically significant differences in LA volume based on the type of AF, with higher volumes observed in patients with persistent AF (119.16 ± 32.38 cc) compared to the rest (90.99 ± 28.34 cc). Regarding the differences between patients with and without recurrence after ablation, only LA volume (P < .05) and periatrial adipose tissue volume (P < .01) were significantly higher in patients with recurrence.
Conclusion
The type of atrial fibrillation, increased left atrial volume, and increased periatrial adipose tissue volume are risk factors for recurrence in patients with atrial fibrillation undergoing pulmonary vein ablation using cryoablation or radiofrequency.

Introduction
Transarterial embolization (TAE) is the gold standard treatment for iatrogenic renal artery pseudoaneurysms (PSA) and pseudoaneurysms with arteriovenous fistula (PSA + AVF), but its impact on renal function has not been sufficiently investigated. The aim of the study is to assess the impact on of TAE on renal function and its technical and clinical effectiveness.
Materials and methods
Sixty-seven embolization procedures in 61 consecutive patients from December 2006 to October 2020 in two centers were retrospectively reviewed for the following parameters: technical and clinical success and failure, embolization materials, type and dimensions of vascular injuries, percentage of post-procedural ischemic renal parenchyma and estimated glomerular filtration rate (eGFR) values before and 1 day after the surgical, percutaneous or endoscopic (SPE) procedure and before, 1 day after and 6 months after TAE.
Results
We identified 44 PSA and 23 PSA + AVF. Technical success was 95.5%, primary clinical success was 90.2% and secondary clinical success was 96.7%. Different embolization materials were used. A significant decrease of the eGFR was found after the SPE procedure. No significant difference was found between eGFR before and after TAE. A minimal significant improvement of the eGFR was found 6 months after TAE. Embolization of larger lesions resulted in larger post-procedural ischemic areas. PSA + AVF were significantly larger (P = .0142) and determined a larger post-procedural ischemic area. No correlation was found between dimensions, kind of vascular injury or post-procedural ischemic area and eGFR.
Conclusion
TAE has high technical and clinical success rates and does not affect renal function negatively, regardless of dimensions or kind of vascular injuries or post-procedural ischemic area.

Background
Cerebral small vessel ischemic disease (SVID) as a common age-related morbidity is the key mechanism of vascular cognitive impairment (VCI). This study uses Cerebral blood flow (CBF) measured by pseudo-continuous ASL MRI in SVID patients with and without cognitive impairment to differentiate VCI from normal aging.
Materials and Methods
In this cross-sectional study, 74 SVID patients, including 35 with diagnosed VCI and 39 without cognitive impairment(control) underwent pCASL-MRI in the resting state. ROI-based approach pre-processing, denoising techniques, and correction for partial volume effects were performed. Regional CBF was compared between severe cognitive impairment (SCI), mild cognitive impairment (MCI), and SVID patients without cognitive impairment.
Results
Total and regional CBF values in the thalamus, left cortex, hippocampus, post cingulate cortex, precuneus, insula, putamen, and middle temporal lobe was lower in VCI compared to SVID, also in SCI compared MCI group. There was a linear correlation between the Mini-Mental State Examination (MMSE) z score and CBF in the thalamus region in SVID participants and between the MMSE z score and CBF in the medial temporal region in MCI participants. The medial temporal atrophy)MTA (z score was significantly correlated with CBF values in the hippocampus and medial temporal regions in SCI and MCI. Also a significant correlation was seen between total CBF and Fazekas score.
Conclusion
Due to the growing prevalence of dementia and the role of CBF as a predictive biomarker, ASL-MRI as a non-invasive method can be easily added to diagnostic tools of cognitive impairment in individuals with SVID to recognize the initiation of VCI.

CT coronary angiography is the most reliable non-invasive imaging technique for ruling out coronary artery disease. However, its specificity is not high. Thus, when coronary stenosis of uncertain functional significance is detected, the recommendation is to perform complementary imaging tests to assess myocardial ischemia. CT myocardial perfusion imaging and CT fractional flow reserve provide added diagnostic accuracy and prognostic value to CT coronary angiography, by increasing its predictive value and facilitating therapeutic decision-making.

The analysis of ethical aspects in clinical research has always been a challenge and has required constant updates.
In short, research ethics is the set of specific principles, rules, and norms of behavior that a research community has decided are appropriate and fair under the premise that research must be valid, reliable, legitimate, and representative.
This non-systematic review brings some ethical concerns that should be considered within the scientific community. Many studies and the development of new artificial intelligence (AI) tools, especially in radiology, make it necessary for the radiology research community to promote debates and establish ethical standards for the practice and development of new AI tools.
临床研究中的伦理方面分析一直是一个挑战，需要不断更新。简而言之，研究伦理是研究界在研究必须具有有效、可靠、合法和代表性的前提下，决定的一套具体的行为原则、规则和规范。本文提出了一个非系统的综述，解决了科学界应该考虑的一些伦理问题。关于人工智能(ai)新工具开发的大量研究，特别是应用于放射学，使得该领域的研究界有必要促进辩论，并建立适用于新人工智能工具实践和开发的伦理原则。The analysis of伦理aspects in clinical research has always been a更新你的挑战与required常数。简而言之，研究伦理是一套具体的原则、规则和行为规范，研究界认为这些原则、规则和行为规范是适当和公平的，前提是研究必须是有效的、可靠的、合法的和具有代表性的。这种非系统的审查带来了一些应该在科学界考虑的伦理问题。许多新的人工智能(AI)工具的研究和发展，特别是在放射学领域，使放射学研究界有必要促进讨论和建立新的人工智能工具的实践和发展的伦理标准。

Breast cancer (BC) has high rates of incidence and prevalence, causing significant impact in our society. Magnetic resonance imaging (MRI) plays a crucial role in its detection and staging. The Oncotype DX Breast Recurrence Score (ODXRS) test can be used to guide decision making regarding adjuvant chemotherapy (CT) in early-stage luminal BC to allow for more tailored cancer treatment. The aim of this article is to review knowledge regarding MRI biomarkers to date according to the BI-RADS® classification and the use of artificial intelligence (AI) in this imaging technique to establish its correlation with the ODXRS test. The latest studies published on AI and MRI present promising findings, and their standardisation could mark a turning point in breast radiology.
