Skeletal-related events due to bone metastases can be prevented by early diagnosis using radiological or nuclear imaging techniques. Nuclear medicine techniques such as Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) have been used for diagnostic imaging of bone for decades. Although it is widely recognized that conventional diagnostic imaging techniques such as Comp Read More

Background Magnetic resonance enteroclysis (MRE) has been widely applied to diagnose Crohn’s disease (CD). Magnetic resonance (MR) at 3.0 T improves signal-to-noise ratio (SNR), shortens image acquisition time, and shows more advantages. Objective This study aimed to retrospectively analyze the diagnostic value of 3.0 T MR imaging for active CD. Methods 48 CD patients hospitalized in our hospital from January 2021 to Read More

Introduction Hydatidosis, a distinctive parasitic ailment, exhibits a broad range of imaging characteristics influenced by the growth stage, resultant complications, and tissue involvement. Its occurrence throughout the human anatomy underscores its ubiquitous propensity. Despite its relatively infrequent manifestation as diffuse hydatosis, the disease assumes particular significance in rural regions. Given its detrimental complic Read More

Background The pathogenesis of breast cancer is characterized by dysregulated cell proliferation, leading to the formation of a neoplastic mass. Conventional methodologies for analyzing carcinomatous distal areas within whole-slide images (WSIs) tissue regions may lack comprehensive insights. Purpose This study aims to introduce an innovative methodology based on convolutional neural networks (CNN), specifically em Read More

Background This case report describes a case of Müllerian duct cyst that occurred in a male retroperitoneum. The cyst lesion is rare and complicated with diaphragmatic hernia. Müllerian duct-derived cyst is a rare developmental disorder that is more common in male pelvic tissues and rare in the retroperitoneum. We investigated the important role of computerized tomography (CT) and magnetic resonance imagin Read More

Background:Although the amygdala has structural and functional abnormalities in Chronic Migraine (CM), less is known about the altered perfusion of the amygdala in CM.Objective:The current study aimed to assess amygdala perfusion in CM using a contrast agent-free and quantitative approach.Methods:15 Normal Controls (NC) and 13 patients with CM during the migraine interval were assessed for brain structure and Read More

BackgroundPositron Emission Tomography (PET) scan stands as a valuable diagnostic tool in nuclear medicine, enabling the observation of metabolic and physiological changes at a molecular level. However, PET scans have a number of drawbacks, such as poor spatial resolution, noisy images, scattered radiation, artifacts, and radiation exposure. These challenges demonstrate the need for optimization in image proces Read More

Objective This study aimed to compare the parametric value of T2 with and without fat suppression (FS) on T2 mapping for the evaluation of extraocular muscles (EOMs) in mild thyroid-associated ophthalmopathy (TAO). Methods We prospectively recruited 44 consecutive patients with mild TAO seen between May 2020 and October 2022 and 26 healthy controls with no history of eye- or thyroid-related or other autoimm Read More

Background In the end stage of kidney disease, abnormal levels of blood calcium, phosphorus, and parathyroid hormone lead to bone metabolism disorders, manifesting as osteoporosis or fibrocystic osteoarthritis. X-ray, CT, and MR are useful for detecting bone lesions in dialysis patients, but currently, computer vision has not yet been used for this purpose. Methods ResNet is a powerful deep CNN model, which has not yet be Read More

Purpose Individuals with depression have an increased risk of cardiovascular disease, and more often have a poor prognosis with cardiovascular disease. This study aimed to investigate the impact of depression on Left Ventricular (LV) alterations using Cardiovascular Magnetic Resonance Feature-tracking (CMR-FT). Methods Seven anesthetized, healthy Chinese miniature swine were included in the study. Basic data, includi Read More

Cervical lymph node metastasis is an important determinant of cancer stage and the selection of an appropriate treatment plan for patients with head and neck cancer. Therefore, metastatic cervical lymph nodes should be effectively differentiated from lymphoma, tuberculous lymphadenitis, and other benign lymphadenopathies. The aim of this work is to describe the performance of Doppler ultrasound and superb microvasc Read More

Background The metastasis of primary breast invasive lobular carcinoma to the gastrointestinal tract and skin is a rare phenomenon, with the simultaneous occurrence of both transfers being more uncommon. Case Presentation This article reports a case of a patient with hormone receptor-positive, HER2-negative breast invasive lobular carcinoma with gastrointestinal tract and skin metastases. The patient was asse Read More

Background:Carotid duplex ultrasonography (DUS) is the primary screening tool for carotid artery stenosis, but has low reliability. MHR, which is the ratio of monocytes to high-density lipoprotein cholesterol (HDL-C), can be a marker for the degree and distribution of extracranial and intracranial atherosclerotic stenosis.Objective:We determined the diagnostic value of DUS+MHR for internal carotid artery (ICA) stenosis.Methods:W Read More

Background: Endometrial Cancer (EC) is a highly heterogeneous cancer comprising both histological and molecular subtypes. Using a non-invasive modality method to trigger these subtypes as early as possible can aid clinicians in establishing individualized treatment. Purpose: The study aimed to clarify the value of the Apparent Diffusion Coefficient (ADC) of EC MRI in determining molecular subtypes. Material and Methods: We r Read More

Background and Objective:The incidence of stroke is rising, and it is the second major cause of mortality and the third leading cause of disability globally. The goal of this study was to rapidly and accurately identify carotid plaques and automatically quantify plaque burden using our automated tracking and segmentation US-video system.Methods:We collected 88 common carotid artery transection videos (11048 frames) with a Read More

Background:Currently, it is difficult to find a solution to the inverse inappropriate problem, which involves restoring a high-resolution image from a low-resolution image contained within a single image. In nature photography, one can capture a wide variety of objects and textures, each with its own characteristics, most notably the high-frequency component. These qualities can be distinguished from each other by looking at the Read More

Background: Previous studies have indicated the abnormality of the globus pallidus in neonates with hyperbilirubinemia. Objective: This study aims to explore the microstructure and cerebral perfusion of globus pallidus in neonatal hyperbilirubinemia by using Diffusion Tensor Imaging (DTI) and Arterial Spin Labeling (ASL) approaches. Methods: Thirty-seven neonates were enrolled in this study, which were classified into Bilirubin-I Read More
