Introduction: This study aimed to evaluate radiological findings in patients with chondroblastoma (CB) in tubular and non-tubular bones (NTBs).
Methods: We retrospectively reviewed the medical records of patients with CB. Data collected included patients' gender and age, type, size and location of bone involved, and imaging findings regarding border, lobulation, calcification, trabeculation, cortical expansion and destruction, periosteal reaction, soft tissue component and fractures.
Introduction: We aimed to retrospectively review the ultrasonography (US) findings of patients with clinically suspected soft tissue infection of the legs and to determine whether there is a correlation between US diagnosis and further clinical management.
Methods: We reviewed the US findings of consecutive patients with clinically suspected soft tissue infection of the legs who were referred for emergency US during a consecutive two-year period. The indications for US were recorded and the findings evaluated.
Objective: To investigate dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) in term of differentiation recurrent malignant soft tissue tumor (MSTT) from post-treatment changes.
Material And Method: DCE-MRI was performed in consecutive patients in two-year periods to differentiate recurrent MSTT from post-treatment (surgery radiotherapy chemotherapy) changes. The steepest slope (SS) ratio between the artery and the lesion, sensitivity, and specificity were calculated.
Introduction: This study aimed to retrospectively review the magnetic resonance (MR) imaging features of the lipomatous tumour in order to differentiate between lipoma and liposarcoma.
Methods: The MR images of 38 patients (24 female and 14 male with a mean age 48 years) in a consecutive five-year period, who had histologically verified lipoma (n is 29) and liposarcoma (n is 9), were retrospectively reviewed. The images were assessed for the number, site, size and margin of the lesions, as well as the signal intensity (homogenous, bright signal on T1-weighted [T1W] image, bright signal suppressed on T1W with fat-suppression image, bright signal on T2-weighted with fat-suppression image), the internal architecture (thin/thick septum, cystic change), the effect on the surrounding tissue (oedema, neurovascular involvement) and the enhancement pattern.
Objective: To study and diagnose meniscal tear of the knee using 3-Tesla (3-T) magnetic resonance imaging (MRI) compared with arthroscopy.
Material And Method: One hundred twenty eight consecutive patients who underwent MRI of the knee using a 3-T magnet between April 2007 and Nov 2008 were included in this study. The inclusion criteria were the patients who had (i) subsequent knee arthroscopy, (ii) available medical records, and (iii) no history of meniscal surgery.
