Objectives: Pancreatic diffusion-weighted imaging (DWI) has numerous clinical applications, but conventional single-shot methods suffer from off resonance-induced artifacts like distortion and blurring while cardiovascular motion-induced phase inconsistency leads to quantitative errors and signal loss, limiting its utility. Multishot DWI (msDWI) offers reduced image distortion and blurring relative to single-shot methods but increases sensitivity to motion artifacts. Motion-compensated diffusion-encoding gradients (MCGs) reduce motion artifacts and could improve motion robustness of msDWI but come with the cost of extended echo time, further reducing signal.

This paper proposes the use of artificial intelligence techniques, specifically the nnU-Net convolutional neural network, to improve the identification of left ventricular walls in images of myocardial perfusion scintigraphy, with the objective of improving the diagnosis and treatment of coronary artery disease. The methodology included data collection in a clinical environment, followed by data preparation and analysis using the 3D Slicer Platform for manual segmentation, and subsequently, the application of artificial intelligence models for automated segmentation, focusing on the efficiency of identifying the walls of the left ventricular. A total of 83 clinical routine exams were collected, each exam containing 50 slices, which is 4,150 images.

Unlabelled: The Bland-White-Garland syndrome, or Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery (ALCAPA) syndrome, is a rare congenital cardiac anomaly often associated with high mortality, if left untreated. We present a case of a 43-year-old female with undiagnosed ALCAPA who initially underwent mitral valve surgery for severe mitral regurgitation, only to require reoperation due to adult-type ALCAPA. Intraoperatively, the discovery of dilated right coronary artery and its branches and absence of the left coronary ostium prompted further investigation, leading to the diagnosis of adult-type ALCAPA.

An 80-year-old woman with a history of B-cell non-Hodgkin lymphoma presented to the emergency department with exertional dyspnea and lower limb edema. A transthoracic echocardiogram revealed a large extracardiac mass invading the right atrium. A diagnostic transcatheter endomyocardial biopsy guided by intracardiac echocardiography was performed.
