Purpose: The aim of this study was to assess the local recurrence rate of giant cell tumour of bone (GCTB) with soft tissue extension, to identify characteristics of the soft tissue extension that can best indicate recurrence of GCTB after intralesional curettage.
Materials And Methods: A total of 48 cases of GCTB with soft tissue extension after intralesional curettage were recruited. Patients were divided into two groups based on various objective features of soft tissue extension including size, number, margins, involvement of adjacent tissues, signal intensity, static enhancement and Jaffe grade.
Purpose: The aim of this study was to investigate the characteristic imaging features of giant cell tumours (GCTs) of the mobile spine.
Materials And Methods: Thirty pathologically proven GCTs of the mobile spine were reviewed. X-ray (n = 18), computed tomography (CT) (n = 24) and magnetic resonance (MR) (n = 21) images were retrospectively evaluated.
Objective: Our purpose was, through the comparison of the characteristics of time-intensity curve on triple-phase dynamic contrast-enhanced MRI among groups of giant cell tumor of bone (GCTB), recurrent benign giant cell tumor of bone (RBGCTB), and secondary malignant giant cell tumor of bone (SMGCTB), to find clues to predict the malignant transformation of GCTB.
Subjects And Methods: 21 patients diagnosed as GCTB were included in this study. All cases took recurrence after intralesional curettage.
Objective: To evaluate criteria to differentiate sacral chordoma (SC), sacral giant cell tumor (SGCT) and giant sacral schwannoma (GSS) with CT and MRI.
Materials And Methods: CT and MR images of 22 SCs, 19 SGCTs and 8 GSSs were reviewed. The clinical and imaging features of each tumor were analyzed.
Article Synopsis
- The study looked at whether a special imaging test called diffusion-weighted imaging (DWI) can help doctors see how well osteosarcoma treatment is working after chemotherapy.
- They checked 35 patients' tumors before and after they got treatment, measuring certain values that show tumor changes.
- The results showed that the DWI values after treatment were higher in patients who responded well to chemotherapy, helping doctors figure out how effective the treatment was.
Purpose: This study was done to investigate X-ray, computed tomography (CT) and magnetic resonance (MR) imaging features of recurrence in giant cell tumour of bone (GCTB) and to evaluate risk factors.
Materials And Methods: Medical records and imaging data were reviewed for 55 cases of recurrent GCTB. All images were reviewed retrospectively and independently by two radiologists experienced in skeletal musculature.
Objective: To study the correlation of liver and spleen volume with the degree of liver fibrosis and cirrhosis induced by hepatitis B virus infection.
Methods: 128 participants who had undergone liver and spleen volumetry were enrolled. The control group consisted of 41 participants who were potential living liver donors.
Objective: To assess the clinical feasibility of diagnosing and staging liver fibrosis by apparent diffusion coefficient (ADC).
Methods: Totally, 43 patients (mean age 29.3 years) with chronic hepatitis by liver biopsy and 7 healthy controls (mean age 39.
