Investigate the quantification accuracy of small lesions in oncological 18F-FDG PET/CT using a deep progressive learning reconstruction method
Abdominal Imaging 5 min.
F-FDG PET/CT is a widely used functional imaging technique essential for diagnosis, staging, treatment monitoring [1, 2–3]. Accurate quantification and high image quality are critical, yet often limited by image noise and contrast. The reconstruction algorithm significantly affects both image quality...
Effect of supraglottic endotracheal tube inserted transorally on preventing hypoxemia in obese patients undergoing sedated bidirectional endoscopy: a prospective randomized controlled clinical trial
Abdominal Imaging 5 min.
Gastroscopy is usually performed under sedation to ease pain and ensure effective and timely completion [1, 2]. It often results in hypoxemia, a common and serious complication due to airway obstruction, respiratory depression, and the inevitable sharing of the upper airway space with the endoscope....
The evolution of endoscopic ultrasound in Saudi Arabia: an expert review of clinical practice and literature
Abdominal Imaging 1 min.
Endoscopic ultrasound (EUS) has emerged as a cornerstone in gastrointestinal diagnostics and therapeutics worldwide. In Saudi Arabia, however, its development has not yet been comprehensively reviewed in the context of evolving clinical practice and training needs. This narrative review synthesises published...
CRLM-GAN: a feature-constrained GAN-based deep learning framework for multi-parametric MRI-based segmentation of colorectal liver metastases before and after chemotherapy
Abdominal Imaging 7 min.
Colorectal cancer accounts for 10.0% of new cancer cases worldwide, while its mortality rate is 9.4%, making it the second leading cause of cancer-related deaths [1]. Colorectal liver metastases (CRLMs) refer to secondary malignant liver tumours originating from primary colorectal cancer and represent...
Foundation model-guided multi-view semi-supervised CT segmentation of liver tumors in resource-constrained settings
Abdominal Imaging 9 min.
The liver serves as the link between metabolic homeostasis and digestive function, and is an extremely important organ in human physiology. Its critical role is profoundly challenged by hepatic malignancies, which constitute a major source of cancer-related morbidity and mortality globally, posing a...
