Clinical application of third-generation dual-source CT-based dynamic imaging reconstruction for pulmonary embolism imaging.
J Cardiothorac Surg
January 2025
Department of Thyroid Breast Cardiothoracic & Vascular Surgery, Beibei District Hospital of Traditional Chinese Medicine, No. 380 Jiangjun Road, Beibei District, Chongqing, 400700, China.
Background: To evaluate the clinical diagnostic value of third-generation dual-source CT for pulmonary embolism, focusing on the optimization of dual-source CT scanning with dynamic reconstruction in acute pulmonary embolism (PE) and various imaging manifestations.
Methods: Eighty-two patients with pulmonary embolism were enrolled and randomly divided into standard CT angiography (SCTA) and dynamic CT angiography (DCTA). DCTA patients were divided into dynamic CT angiography arterial phase (DCTAa), time phase Angiography reconstruction (TMIP-CTA), and 4D noise reduction TMIP-CTA according to the image reconstruction.
Metanephric stromal tumor as a rare differential diagnosis of a renal mass in children - a case report.
Pediatr Radiol
January 2025
Pediatric Radiology, Kinderradiologie, Charité - Universitätsmedizin Berlin, corporate member of Freie Universität Berlin and Humboldt-Universität Zu Berlin, Augustenburger Platz 1, Berlin, 13353, Germany.
This report presents the case of a benign metanephric stromal tumor that occurred in the kidney of a 5-year-old boy and in which differentiation from a nephroblastoma was successful. Radiological assessment played the decisive role in this case, as the low initial volume, a high apparent diffusion coefficient, and lack of rapid tumor growth were considered atypical for a nephroblastoma. The boy underwent successful kidney-preserving resection without neoadjuvant chemotherapy, and intraoperative contrast-enhanced ultrasound examination helped to accurately define the tumor margins.

Acta Endocrinol (Buchar)
January 2025
Dokuz Eylül University, Faculty of Medicine, Division of Pediatric Endocrinology.
Context: Osteonecrosis (ON) is bone death caused by inadequate blood supply and its optimal management remains uncertain.
Objective: We describe the outcomes of BP (pamidronate) treatment in our patients.
Design: Data regarding clinical, laboratory, magnetic resonance imaging (MRI) studies, and bone mineral density measurements (BMD) were recorded before and one year after treatment (reevaluation).

Apollonia" University of Iasi, Faculty of Dental Medicine, 11 Pacurari Str., 700511, Iasi, Romania.
Background: In the context of modern oncology, radiogenic elements have emerged as pivotal tools for targeted cancer therapies. Elements like Iodine-131 and Yttrium-90 offer unique radiological properties that allow precise treatment delivery. This article explores their growing importance and potential in reshaping the landscape of cancer therapy.

Deep multiple instance learning (MIL) pipelines are the mainstream weakly supervised learning methodologies for whole slide image (WSI) classification. However, it remains unclear how these widely used approaches compare to each other, given the recent proliferation of foundation models (FMs) for patch-level embedding and the diversity of slide-level aggregations. This paper implemented and systematically compared six FMs and six recent MIL methods by organizing different feature extractions and aggregations across seven clinically relevant end-to-end prediction tasks using WSIs from 4044 patients with four different cancer types.
