Discrepancy between X-ray and CT assessment in the Mirels score for long bone metastasis
Orthopedics Imaging 3 min.
The Mirels score is a prediction system proposed by Mirels in 1989 to evaluate the risk of pathological fracture of long bone metastasis within six months and comprises four factors: pain, (anatomical) site, size, and lesion (radiographic appearance). Each factor is rated from one to three points, and...
Multiple brown tumors caused by parathyroid adenoma identified by 18F-FDG PET/CT in a patient with thalassemia: a case report
Orthopedics Imaging 3 min.
The parathyroid tumor secretes excessive amounts of parathyroid hormone, leading to hypercalcemia and associated complications such as osteoporosis, bone fractures, and brown tumors [1]. Brown tumors are rare skeletal lesions characterized by their distinctive brown color, which results from increased...
MRI-based habitat analysis for differentiating benign and malignant vertebral compression fractures
Orthopedics Imaging 6 min.
Vertebral compression fractures (VCFs) are prevalent conditions within the skeletal system encountered in clinical practice. The increasing trend in their incidence is notably associated with the intensification of population aging [1]. VCFs significantly impair patients’ quality of life by inducing...
CT-assessed pectoralis major muscle measurements as risk factors for low neoadjuvant chemotherapy efficacy in osteosarcoma: a retrospective study
Orthopedics Imaging 4 min.
Osteosarcoma is a rare kind of malignant tumor of mesenchymal origin with an annual incidence of 3–4 patients per million. As the most common malignant bone neoplasm, osteosarcoma is leading to high mortality [1, 2]. In the past few decades, with the development of adjuvant chemotherapy and neoadjuvant...
Dual-Source Dual-Energy Imaging Using Photon-Counting Detector CT for Bone Edema Detection: Leveraging Tin Prefiltration for Improved Spectral Performance.
Orthopedics Imaging 1 min.
The aims of the study were to evaluate the spectral performance of an investigational dual-source (DS) scan mode using a tin (Sn) filter on the B-subsystem of a clinical photon-counting detector (PCD) CT system and to demonstrate improved material decomposition performance using clinical examples of...
