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.

Chimeric antigen receptor-engineered (CAR) T-cell therapy is an effective immunotherapy for aggressive hematologic cancers. However, it can lead to complications such as immune effector cell-associated neurotoxicity syndrome (ICANS), or complications related to the immunosuppressive status of these patients. The role of imaging in this context is essential to help in ICANS diagnosis and to rule out other potential diagnosis, such as central nervous system infections. Two cases are presented to illustrate this clinical problem.
Case 1: describes a 38-year-old patient with diffuse large B-cell lymphoma who developed ICANS after CAR T-cell therapy. MRI revealed signs of leukoencephalopathy. Case 2:involves a 57-year-old patient with mantle-cell lymphoma who presented neurologic symptoms -clinically suggestive of ICANS- after CAR-T therapy.

These two cases highlight the importance of MRI in clinical practice after CAR T-Cell Therapy underscoring the role of MRI in the diagnosis of complications in patients with neuropsychiatric symptoms.
T细胞的免疫治疗与空想抗原受体(Chimeric Antigen Receptor-engineered T-cell [CAR-T])在某些血液肿瘤是有效的,但是有风险相关联的神经细胞免疫efectoras综合征(Immune effector cell-associated neurotoxicity综合征[ICANS]),和其他抑制造成的并发症。磁共振成像(mri)可以帮助诊断ICANS,排除其他诊断,如中枢神经系统感染。这里有两个例子来说明这一点。病例1:38岁大细胞弥漫性B淋巴瘤患者,CAR-T后ICANS治疗。mri显示有脑白质病的迹象。病例2:57岁,幔细胞淋巴瘤患者,神经系统症状提示ICANS后治疗CAR-T。mri显示海马异常,表明边缘脑炎。这些病例强调了CAR-T治疗后mri的重要性,并强调了其在诊断神经精神症状患者并发症中的作用。化学抗原受体工程(CAR) t细胞疗法是一种治疗侵袭性血液病的有效免疫疗法。然而,它可能导致并发症,如免疫效应细胞相关神经毒性综合征(ICANS),或与这些患者的免疫抑制状态相关的并发症。在这种情况下,成像的作用对于帮助诊断ICANS和指导其他潜在的诊断,如中枢神经系统感染至关重要。= =地理= =根据美国人口普查,这个县的总面积是,其中土地和(1.641平方公里)水。病例1:描述一名38岁的弥漫性大b细胞淋巴瘤患者,在汽车t细胞治疗后发展为ICANS。MRI显示脑白质病的迹象。病例2:涉及一名57岁的幔细胞淋巴瘤患者,在CAR-T治疗后出现神经系统症状(临床提示ICANS)。MRI显示边缘脑炎的迹象。这两例病例强调了核磁共振在t细胞治疗后临床实践中的重要性,从而降低了核磁共振在神经精神症状患者并发症诊断中的作用。

Synovial sarcoma (SS) is a rare malignant neoplasm of the soft tissue adjacent to joints. It is the most commonly diagnosed non-rhabdomyosarcoma soft-tissue sarcoma (STS) in childhood (30%). Its most frequent location is the knee and ankle, and it is the most common STS to affect the foot. Unlike other STS, it has slow growth and an earlier age at diagnosis (adolescents and young adults), which is why many cases are initially misdiagnosed as benign processes. Magnetic resonance imaging (MRI) is key due to its characterisation capabilities as SS shares features with other STS. Definitive diagnosis is achieved through a pathological study that shows the pathognomonic translocation t(x;18)(p11;q11) with the fluorescence in situ hybridisation (FISH) technique. The objective of this article is to highlight the key characteristics that are useful for diagnosing SS, fundamentally through the use of radiological imaging techniques, as well as nuclear medicine and pathological studies, illustrated with cases diagnosed in our centre.
