Objective To verify the multiphase ratio of Computer Tomography-value between the renal cortex and renal medulla, which can be used to concisely evaluate renal function in kidney recipients. Methods Fifty-eight kidney recipients were retrospectively enrolled and divided into the Normal group (eGFR≥90 mL/min/1.73m2) and Abnormal group (eGFR<90 mL/min/1.73m2) according to Chronicle Kidney Disease Epide Read More

Objective The aim of this study was to investigate the feasibility of muscle CT radiomics in identifying gout. Materials and Methods A total of 30 gout patients and 20 non-gout cases with CT examinations of ankles were analyzed by using the methods of CT radiomics. CT radiomics features of the soleus muscle were extracted using the software of a 3D slicer, and then gout cases and non-gout cases were compared. The radiomics Read More

Background Magnetic Resonance Imaging (MRI) data acquisition includes several sequences that might be optimized to reduce the scan time. Objective This study aimed to investigate the impact of gadolinium chelate administration timing on scan duration and image quality in Diffusion-weighted Imaging (DWI) and T2-weighted Imaging (T2WI) during abdominal MRI examinations. Methods A prospective study was conduc Read More

Background Accurately modeling respiratory motion in medical images is crucial for various applications, including radiation therapy planning. However, existing registration methods often struggle to extract local features effectively, limiting their performance. Objective In this paper, we aimed to propose a new framework called CvTMorph, which utilizes a Convolutional vision Transformer (CvT) and Convolutional Neural N Read More

Background Patients with malignant tumors often develop bone metastases. SPECT bone scintigraphy is an effective tool for surveying bone metastases due to its high sensitivity, low-cost equipment, and radiopharmaceutical. However, the low spatial resolution of SPECT scans significantly hinders manual analysis by nuclear medicine physicians. Deep learning, a promising technique for automated image analysi Read More

Introduction Eosinophilic gastroenteritis (EGE) is a rare immune-mediated chronic inflammatory disorder, which is classified into 3 types according to the affected gastric wall layer. The serosal-type EGE is the least common type. Gastric oral contrast-enhanced ultrasonography (OCEUS) may show some specific changes in the serosal-type EGE. Herein, we reported OCEUS findings in a serosal-type EGE case. Case Presentation Read More

The most common primary malignant brain tumor is glioblastoma. Glioblastoma Multiforme (GBM) diagnosis is difficult. However, image segmentation and registration methods may simplify and automate Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) scan analysis. Medical practitioners and researchers can better identify and characterize glioblastoma tumors using this technology. Many se Read More

Aim The automatic computer-assisted mammogram classification system is important for women patients to detect and diagnose the cancer regions. In this work, the mammogram images are classified into three cases: healthy, benign and cancer, using the proposed Resource Efficient Convolutional Neural Network (RECNN architecture). Methods The proposed mammogram image classification system consists of Data Read More

Background Capitellar injury (CI) includes capitellar cartilage injury (CCI) and capitellar fracture (CF). A comprehensive classification of CI concurrent with radial head fracture (RHF) that can guide surgical strategy is lacking in the literature. Therefore, this study aimed to introduce a comprehensive classification of CI concurrent with RHF and investigate its value. Methods A total of 35 patients with CI concurrent with Read More

Background Mediastinal venous malformation (MVM) and fusiform superior vena cava aneurysm (F-SVCA) are both rare congenital vascular anomalies. Case Presentation A 46-year-old male presented with acute ischemic stroke of unknown etiology. Computed tomography (CT) angiography revealed the coexistence of MVM and F-SVCA. Diagnostic venography demonstrated a significant reduction in blood flow ve Read More

Introduction Intrahepatic primary osteosarcoma is a rare disease with a very low incidence but a very poor prognosis. A total of 12 cases have been previously reported, and in most of these cases, intra-focal calcification was observed. This paper aims to report a case of non-calcified intrahepatic primary osteosarcoma. Case Description We hereby report a female patient with hepatitis B for 20 years, identified during Read More

Introduction: “Pelvic rib”, “pelvic digit (finger)”, or “eleventh digit (finger)” is a rare congenital anomaly, in which a finger-like bony structure is present in the soft tissue in the pelvic or abdomen (less common) area. Case Presentation: This case report presents a symptomatic “pelvic digit” discovered in a patient referred to the radiology department after prolonged unilateral hip pain, especially during long walks. To our kno Read More

Background Chest X-ray image classification for multiple diseases is an important research direction in the field of computer vision and medical image processing. It aims to utilize advanced image processing techniques and deep learning algorithms to automatically analyze and identify X-ray images, determining whether specific pathologies or structural abnormalities exist in the images. Objective We present the MMPDenseN Read More

Background The neural mechanisms underlying Congenital Sensorineural Hearing Loss (CSNHL) remain elusive. Objective This study evaluated the function of the glymphatic system in children with CSNHL compared to normal-hearing children using the DTI-ALPS approach, which utilizes diffusion tensor imaging along the perivascular space. Methods Twenty-six children with CSNHL and 30 age- and sex-matched Healthy C Read More

Background Transcatheter radiofrequency ablation is one of the main treatments for atrial fibrillation, but related complications of this surgery are uncommon. Case Presentation Here, we report a 70-year-old elderly male patient with atrial fibrillation who experienced severe abdominal pain early after undergoing radiofrequency ablation; related imaging examinations suggested that the patient had intestinal edema and thick Read More

Objective The purpose of this study was to compare the image quality of different MRI sequences regarding the presentation of Dermatofibrosarcoma Protuberans (DFSP). Materials and Methods We retrospectively collected MRI images of 40 patients who had been pathologically diagnosed with DFSP, including 21 primary tumors and 19 recurrent tumors. The image quality of different MRI sequences Read More

Introduction: Osteoid osteoma (OO) is a painful benign bone tumor. Typically, it causes pain that is most noticeable during the night, which is improved by nonsteroidal anti-inflammatory drugs. In the treatment of symptomatic lesions, open surgery for nidus removal is the gold standard. However, surgical technical difficulties and morbidities vary by location. Percutaneous radiofrequency ablation (RFA) therapy guided by c Read More

Background Prostate cancer, a significant contributor to male cancer mortality globally, demands improved diagnostic strategies.
