The aim of this study was to investigate the characteristic imaging features of giant cell tumours (GCTs) of the mobile spine. 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. Five tumours were located in the(More)
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. A total of 48 cases of GCTB with soft tissue extension after intralesional curettage were recruited.(More)
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(More)
OBJECTIVES The purpose of our study is to investigate whether diffusion-weighted imaging (DWI) is useful for monitoring the therapeutic response after neoadjuvant chemotherapy in osteosarcoma of long bones. MATERIALS AND METHODS Conventional magnetic resonance imaging (MRI) and DWI were obtained from 35 patients with histologically proven osteosarcomas.(More)
OBJECTIVE To retrospectively compare focal interstitial fibrosis (FIF), atypical adenomatous hyperplasia (AAH), adenocarcinoma in situ (AIS), and minimally invasive adenocarcinoma (MIA) with pure ground-glass opacity (GGO) using thin-section computed tomography (CT). MATERIALS AND METHODS Sixty pathologically confirmed cases were reviewed including 7(More)
Numerous studies have recently suggested that miRNAs contribute to the development of various types of human cancer as well as to their proliferation and metastasis. The aim of this study was to investigate the functional significance of miR-126 and to identify its possible target genes in osteosarcoma (OS) cells. Here, we found that expression level of(More)
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. RESULTS The mean ages of SC, SGCT and GSS were 55.1 ±(More)
To determine the role of MRI in the early diagnosis of tubal ectopic pregnancy (EP). Clinical and MRI features of 27 cases of tubal pregnancy were reviewed. A thick-walled gestational sac (GS)-like structure was demonstrated lateral to the uterus in all cases. On T2-weighted images, the thick wall typically exhibited 3 discrete rings in 22 cases (81 %),(More)
