Machine Learning (ML) plays an essential part in the research area of medical image processing. The advantages of ML techniques lead to more intelligent, accurate, and automatic computeraided detection (CAD) systems with improved learning capability. In recent years, deep learning-based ML approaches developed to improve the diagnostic capabilities of CAD systems. This study reviews image enhancement, ML and Read More

Background: Many studies have shown that vertebral trabecular attenuation measured on CT scan corresponds well to DXA results for bone mineral density. These studies were based on crosssectional data. Hence, there were limitations in explaining the constantly changing vertebral trabecular attenuation from CT and T-score from DXA over time. Objective: This study aimed to determine the longitudinal association b Read More

Background: As the largest concentration of neural stem cells in adult brain, the subventricular zone (SVZ) is considered to be a potential source of glioblastoma (GBM) occurrence in recent years. Methods: In this study, 116 patients with glioblastoma treated at PLA General Hospital were retrospectively reviewed. The features of SVZ contacting glioblastoma were analyzed in terms of MR imaging and MGMT promoter meth Read More

Background: Facial information acquired via three-dimensional reconstruction of head computed tomography (CT) data may be considered personal information, which can be problematic for neuroimaging studies. However, no study has verified the relationship between slice thickness and face reproducibility. This study determined the relationship and match rate between image slice thickness and face detection accur Read More

Objective: to investigate the feasibility of gadoxetic acid (Gd-EOB-DTPA) enhanced MRI combined with T1 mapping in quantitative hepatic function assessment. Methods: this study retrospectively enrolled 94 patients with Gd-EOB-DTPA enhanced MRI combined with T1 mapping, divided into group A (grade A, n=73), group B (grade B, n=14) and group C (grade C, n=7) based on Child-Pugh classification. Liver T1 relaxation tim Read More

Objective: To explore the diagnostic value and severity of acute kidney injury (AKI) in patients with acute pancreatitis (AP) using intravoxel incoherent motion imaging (IVIM), diffusion tensor imaging (DTI), and diffusion kurtosis imaging (DKI). Methods: 224 AP patients, categorized into either the AKI group or the non-AKI group, were retrospectively analyzed in this study. MRI sequences included routine abdominal, IVIM, Read More

Background: Diffuse leptomeningeal glioneuronal tumors (DL-GNT) are rare glioneuronal neoplasms with oligodendroglioma-like cells. These tumors can present as a dominant intracranial mass or as a solitary spinal cord mass without leptomeningeal involvement. In this study, we aimed to determine the magnetic resonance imaging and histopathological features, treatment modalities, and clinical outcomes of the paren Read More

Background: PET imaging is one of the most widely used neurological disease screening and diagnosis techniques. Aims: Since PET involves the radiation and tolerance of different people, the improvement that has always been focused on is to cut down radiation, in the meantime, ensuring that the generated images with low-dose tracer and generated images with standard-dose tracer have the same details of images. Met Read More

Background: Traditional radiography angles do not adequately reveal the shape and position of the right ventricular pacing electrode. Objective: This study aimed to explore better radiography angles with the help of cardiac computed tomography (CT). Methods: We analyzed the cardiac CT images of consecutive outpatients from 2018 to 2019. The right anterior oblique (RAO) 30° and the left anterior oblique (LAO) 40° were Read More

Background: Point shear wave elastography (pSWE) is used to provide quantitative information about the elasticity of the tissues. It has been used in many clinical applications to identify diseases early. This study aims to assess the suitability of pSWE to evaluate pancreas tissue stiffness and provide normal reference values for healthy pancreas tissues. Methods: This study was conducted in the diagnostic department at a tert Read More

Purpose: This study proposes a method for improving the accuracy of three-dimensional (3D) models generated through cone-beam computed tomography (CBCT). Methods: A 3D cuboid model fitted with a ¼-scale dentition on its top surface was constructed to simulate an alveolar bone with teeth. A physical specimen of the model was printed and the distance between its opposite sides was measured using a vernier cali Read More

Background: Video capsule endoscopy (VCE) is an attractive method for diagnosing and objectively monitoring disease activity in celiac disease (CeD). Its use, facilitated by artificial intelligence- based tools, may allow computer-assisted interpretation of VCE studies, transforming a subjective test into a quantitative and reproducible measurement tool. Objective: To evaluate and compare objective CeD severity assessment as d Read More

Objective: Thymic cavernous hemangioma (CH) as a benign lesion is extremely rare, and it is very difficult to distinguish it from other anterior mediastinal tumors on imaging. Case Presentation: We treated a 63-year-old woman with thymic CH that was incidentally found by chest computed tomography (CT). Contrast-enhanced chest CT described an anterior superior mediastinal mass, approximately 2.5cm in diameter, with Read More

Introduction/Background: Central venous catheters, which provide a unique convenience in the management of critical patients, have many advantages, as well as early and late complications. Early complications include pneumothorax, vascular perforation, hematoma formation, air embolism, or catheter malposition that may occur during or shortly after catheter insertion. Late complications include infection, venous Read More

Background: I-131 uptake in the breast could be occasionally observed in differentiated thyroid cancer who received I-131 scintigraphy or therapy. Herein, we report a postpartum patient with papillary thyroid cancer with breast uptake who received I-131 therapy. Case Report: A 33-year-old postpartum woman with thyroid cancer received 120mCi(4440MBq) I- 131 therapy 5 weeks after she ceased to breastfeed. The second Read More

Purpose: To identify MRI findings for injuries to periarticular soft tissue structures that were related to isolated greater tubercle fracture. Materials and Methods: 16 patients (mean age: 53.8, range 30-71 yrs) were enrolled and diagnosed with isolated greater tubercle (GT) fracture with CT and MRI and underwent shoulder arthroscopy from September 2009 to April 2019. Two musculoskeletal radiologists were blinded to the pati Read More
