To evaluate the incidence, quantity, and presentation of intra- and extraosseous edema accompanying benign and malignant primary bone lesions, the magnetic resonance (MR) studies of 63 consecutive patients with histologically proven primary bone tumors were reviewed. MR scans were assessed for the
To study the value of dual energy computed tomography in distinguishing soft tissue infiltration from surrounding soft tissue edema in rabbit malignant bone tumor, a malignant bone tumor model was established through implantation of VX2 tumor fragments into the tibiae of rabbits. Tumor adjacent soft
BACKGROUND
Several reports have shown peritumoral edema accompanying primary bone tumors demonstrated by magnetic resonance imaging (MRI). However, the mechanism of this inflammatory reaction is still unclear. The authors postulated that the reaction was caused by some chemical mediators including
The roles of magnetic resonance imaging (MRI) in the diagnosis and treatment of bone tumors are reviewed. Most bone tumors can be detected on plain radiography or bone scintigraphy. MRI is helpful in detecting tumors that do not destroy bone matrix or suppress reactive bone formation. Detailed
This study aims to investigate the choice of graft or cement, the relationship between the graft types and union rates, functional results, and complications in hand and wrist benign bone lesions while also evaluating the diagnosis and treatment modalities of lesions with high The purpose was to analyze the value of quantitative parameters of DCE-MRI in evaluating micro-infiltration of malignant bone tumors.Methods
Thirty-nine New Zealand white rabbits were used to establish malignant
bone tumor models by implanting VX2
The methods of fat and water selective magnetic resonance (MR) imaging and localized 1H MR spectroscopy were evaluated in the course of 37 examinations on 27 primary bone tumors. These methods are capable of demonstrating small amounts of lipids inside the tumors and subtle edema in the adacent bone
To explore the incidence and significance of intra- and extra-osseous edema associated with benign tumors and tumor-like diseases.Methods
Magnetic resonance imaging (MRI) data from 300 benign osseous tumors and tumor-like diseases diagnosed by
In the recent literature on benign bone tumors, papers have highlighted the atypical appearances of intracapsular osteoid osteoma, the characteristic (yet not pathognomonic) feature of fluid-fluid levels on CT and MR imaging of aneurysmal bone cysts, the difficulties of MR imaging of giant cell
Osteoid osteoma (OO) is a benign bone tumor producing non-mineralized bone matrix (i.e., osteoid). While peritumoral edema is commonly found in OO, extensive bone marrow edema has been reported less frequently. Furthermore, the micro-morphological characteristics of the nidus and its central
OBJECTIVE
The aim of this study was to assess the interreader agreement and diagnostic accuracy of morphologic magnetic resonance imaging (MRI) analysis and quantitative MRI-based texture analysis (TA) for grading of cartilaginous bone tumors.
METHODS
This retrospective study was approved by our
OBJECTIVE
The aim of this study was to investigate the usefulness of dual-energy computed tomography (CT) spectral imaging for differentiating intramedullary microscopic invasion from simple marrow edema in a rabbit VX2 carcinoma model.
METHODS
VX2 tumors were implanted into the right tibiae of 30
We studied the cases of eleven patients in whom a rotationplasty had been done after wide resection of the distal part of the femur. All patients had had a malignant tumor of bone, but none had the complication of edema or leakage of lymph after the rotationplasty. We made lymphoscintiscans soon
18F-Fluorodeoxyglucose PET has been used to evaluate a wide array of inflammatory and neoplastic pathologies. MR imaging has great soft tissue resolution and high accuracy for detection of edema. Combining PET with MR imaging offers substantial advantages in musculoskeletal imaging. Specifically,
Osteoid osteoma is a benign primary bone tumor of unknown etiology that occurs most commonly in males during adolescence and early adulthood. Osteoid osteoma affects the spine in 20% of cases, and may cause spinal deformity, stiffness, and pain that may sometimes be worst at night. We present a
