Article Synopsis
- Takayasu's Arteritis (TA) is a rare and chronic condition affecting large blood vessels, which can result in serious heart problems and potentially life-threatening situations.
- A 34-year-old woman with a heart murmur experienced chest pain, and imaging revealed multiple cardiac issues leading to her diagnosis of TA.
- The case emphasizes the importance of early detection and multimodal imaging for patients with unusual symptoms and heart-related complications, especially those with valvular diseases.
Anatomy: We aim to review the anatomy of the moderator band (MB) and the trabeculated right ventricle (RV).
Pathology: We thoroughly describe the morphological variations of the MB and its spatial relationship with the right ventricular anterior papillary muscle, its muscular trabeculations, and the free wall.
Imaging Correlation: We provide echocardiography, computed tomography, and magnetic resonance imaging to better understand histologic specimens of the MB, the trabeculated RV, and the right ventricular papillary muscles.
Article Synopsis
- * Results showed high sensitivity for detecting fractures and pneumothorax (100% for both), moderate for pulmonary opacity (AI: 76%, resident: 71%), and lower sensitivity for pulmonary nodules (AI: 33%, resident: 75%).
- * The AI system also frequently labeled cases as "doubtful," while the resident showed more confidence; overall, the agreement between the AI and the resident was only fair, suggesting limitations of the AI in detecting some important findings.
Article Synopsis
- Brain plasticity varies after multistep surgery for low-grade gliomas, and personalized neurosurgical approaches using functional imaging can enhance recovery outcomes.
- A study involving four patients with left frontal low-grade gliomas near the supplementary motor area complex (SMAC) showed that surgical interventions did not result in permanent neurological deficits, and some patients exhibited new activity in the right hemisphere after left-side resection.
- The findings suggest SMAC operates as a flexible cortico-subcortical network that can reorganize to compensate for neurological deficits, emphasizing the role of the left middle frontal gyrus in this process.
Article Synopsis
- Myocardial blood flow (MBF) and myocardial perfusion reserve (MPR) from stress cardiovascular magnetic resonance (CMR) effectively identify obstructive coronary artery disease (obCAD) and may outperform conventional qualitative assessments by experienced physicians.
- In a study of 127 individuals, lower global sMBF and MPR were observed in patients with obCAD compared to those without, indicating a significant correlation with disease presence.
- The statistical analysis showed that the area under the curve (AUC) for quantitative sMBF and MPR was at 0.90 and 0.86, respectively, which is higher than the AUCs ranging from 0.69 to 0.88 found in traditional qualitative assessments
Association between subclinical atherosclerosis burden and unrecognized myocardial infarction detected by cardiac magnetic resonance in middle-aged low-risk adults.
Eur Heart J Cardiovasc Imaging
June 2024
Aims: Evidence on the association between subclinical atherosclerosis (SA) and cardiovascular (CV) events in low-risk populations is scant. To study the association between SA burden and an ischaemic scar (IS), identified by cardiac magnetic resonance (CMR), as a surrogate of CV endpoint, in a low-risk population.
Methods And Results: A cohort of 712 asymptomatic middle-aged individuals from the Progression of Early SA (PESA-CNIC-Santander) study (median age 51 years, 84% male, median SCORE2 3.
Objective: Experimental evidence suggests that metabolic syndrome (MetS) is associated with changes in cardiac metabolism. Whether this association occurs in humans is unknown.
Research Design And Methods: 821 asymptomatic individuals from the Progression of Early Subclinical Atherosclerosis (PESA) study (50.
White-Matter Lesions and Cortical Cerebral Blood Flow Evaluation by 3D Arterial Spin-Labeled Perfusion MRI in Asymptomatic Divers: Correlation with Patent Foramen Ovale Ocurrence.
J Clin Med
April 2023
Cerebral white-matter lesions (cWML) can be caused by dilation of Virchow-Robin spaces or may correspond to true lacunar ischemic lesions. The aim of our study was to evaluate in asymptomatic divers the relationship between the presence of patent foramen ovale (PFO) and cWML, as well as their possible effects on cortical cerebral blood flow (CBF) by magnetic resonance (MRI) through the arterial spin labeling (ASL) sequence. Transthoracic echocardiography was performed for the identification of PFO, and cerebral magnetic resonance including the 3D-ASL sequence for CBF quantification.

- Benign cardiac tumors are rare, with cardiac myxoma being the most common; however, left intraventricular presentations are unusual and require consideration of other tumors like papillary fibroelastoma.
- A 73-year-old woman had a cardiac mass identified via echocardiography after experiencing a transient ischemic attack, showing characteristics in cardiac magnetic resonance imaging that suggested a papillary fibroelastoma despite initial indications of a cardiac myxoma.
- The case illustrates that cardiac magnetic resonance (CMR) can effectively differentiate between papillary fibroelastoma and cardiac myxoma, especially when the mass size and mobility allow for detailed tissue characterization.
Breast augmentation is one of the most common aesthetic procedures performed in the United States. Several techniques of breast augmentation have been developed, including the implantation of breast prostheses and the injection of autologous fat and other materials. The most common method of breast augmentation is to implant a prosthesis.
View Article and Find Full Text PDFBackground: Post-COVID-19 patients may incur myocardial involvement secondary to systemic inflammation. Our aim was to detect possible oedema/diffuse fibrosis using cardiac magnetic resonance imaging (CMR) mapping and to study myocardial deformation of the left ventricle (LV) using feature tracking (FT).
Methods: Prospective analysis of consecutively recruited post-COVID-19 patients undergoing CMR.
Background: Even when low-density lipoprotein-cholesterol (LDL-C) levels are lower than guideline thresholds, a residual risk of atherosclerosis remains. It is unknown whether triglyceride (TG) levels are associated with subclinical atherosclerosis and vascular inflammation regardless of LDL-C.
Objectives: This study sought to assess the association between serum TG levels and early atherosclerosis and vascular inflammation in apparently healthy individuals.
Background: Left ventricular (LV) hypertrabeculation fulfilling noncompaction cardiomyopathy criteria has been detected in athletes. However, the association between LV noncompaction (LVNC) phenotype and vigorous physical activity (VPA) in the general population is disputed.
Objectives: The aim of this study was to assess the relationship between LVNC phenotype on cardiac magnetic resonance (CMR) imaging and accelerometer-measured physical activity (PA) in a cohort of middle-aged nonathlete participants in the PESA (Progression of Early Subclinical Atherosclerosis) study.
Purpose Of Review: First, an anatomical and functional review of these cortical areas and subcortical connections with T-fMRI and tractography techniques; second, to demonstrate the value of this approach in neurosurgical planning in a series of patients with tumors close to the SMA.
Recent Findings: Implications in language and cognitive networks with a clear hemispheric lateralization of these SMA/pre-SMA. The recommendation of the use of the advanced neuroimaging studies for surgical planning and preservation of these areas.
Background: In the last decade, the capacity of magnetic resonance (MR) to evaluate congenital anomalies has improved substantially. To date, only a few studies have evaluated the value of 4D-flow MRI in shunt assessments.
Purpose/hypothesis: To assess the intra- and interobserver variability of 4D-flow MRI in patients diagnosed with cardiac/extracardiac shunt.
Article Synopsis
- Gadolinium-perfusion MR can detect gray matter abnormalities in early multiple sclerosis (MS), which may relate to cognitive issues like working memory, with arterial spin labeling (ASL) being a non-invasive alternative for studying these changes.
- A study involving 19 healthy controls and 28 MS patients showed reduced cerebral blood flow and increased bolus arrival time in MS patients compared to controls, indicating significant perfusion alterations.
- The findings suggest that ASL could serve as a useful tool for monitoring MS, as it identifies perfusion changes even when structural changes aren’t visible; further long-term studies are necessary to confirm its effectiveness as a biomarker.
