Objective:To investigate the applied value of3.0T magnetic resonance diffusion weighted imaging (MR-DWI) in the qualitative diagnosis of musculoskeletal benign and malignant tumors.Methods:60patients with musculoskeletal tumors pathologically confirmed by surgery or biopsy underwent conventional MRI and DWI (different b values of300,600and900s/mm2). Array spatial sensitivity the encoding technique (ASSET) and single-shot echo planar imaging (SS EPI) sequence [...]
BackgroundThe eye is a vital organ.Orbital structure stems from three germ layers which are theepidermal ectoderm,mesoderm and neural ectoderm.Any germ layers can generateneoplasms, the tumor of surrounding structures can spread to the orbit and the tumor ofother parts far from the orbital can be transferred.These situations result in more than100different clinical pathologies affecting the orbit.So [...]
Objective To evaluate the value of diffusion-weighted imaging and dynamiccontrast-enhanced MRI in the diagnosis of focal hepatic lesions.Materials and Methods108cases with focal hepatic lesions were collected from theFirst Affiliated Hospital of Soochow University during the period of December2010toJanuary2012. All the lesions were proved by operation or puncture pathology, or incombination with ultrasound，MRI and（or） CT, or [...]
Background and purposeOsteosarcoma is a primary malignant tumour of the skeleton characterised by the direct formation of immature bone or osteoid tissue by the tumour cells. It is most frequent malignant tumour occurred in childhood and adolescence, and it is the most common primary malignant tumour besides multiple myeloma. The most common site occurs around [...]
Part1The Application of MRI Scan in Evaluating the Efficacy of TACE and in forcasting before the ProcedureObjective:Investigate the predicting role of MRI in evaluating the therapeutic efficacy and the value of follow-up after transarterial chemoembolization.Method:89cases analyzed Retrospectively, were113lesions’MRI features before and after TACE including the plain scan, dynamic contrast enhanced scan and DWI serials, were [...]
Background and objectiveAround35%of colorectal cancer patients who undergo curative surgical treatment will develop recurrent disease,the majority of which occurring during the first3years after surgery,approximately5-15%of patients will develop a locoregional recurrence.These local recurrences are associated with significant morbidity and impair quality of life. Re-resection of local recurrence can significantly improve the5-year survival of colorectal cancer patients.Therefore [...]
Objective To study the performance of axillary lymph nodes on diffusion weighted imaging (DWI), and evaluate the value of ADC and ADC ratio between lymph node and primary tumor in differential diagnosis of axillary lymph nodes metastasis in patients with breast cancer.Materials and Methods In the36consecutive patients who underwent breast imaging fromm March1,2011, to September31,2011,79axillary [...]
Objective: To explore the feasibility and value of dynamic diffusionweighted imaging in the assessment of the treatment response of hepaticcarcinoma by studying the characteristics of the rabbit models of hepatic VX2carcinoma in DWI at different times after Radio-frequency ablationMaterials and Methods: 20 rabbit models of hepatic VX2 carcinomawere constructed successfully，and were randomly divided into 4 [...]
Objective:Assess the value of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and diffusion weighted imaging (DWI) in monitoring therapy effect of neoadjuvant chemotherapy(NAC) in patients with locally advanced breast cancer(LABC) and evaluating residual disease after NAC, to provide a reliable basis for judging prognosis and protocol making.Materials and methods:The prospective study included26lesions in24patients with LABC (UICC [...]
Objective:To evaluate the efficacy of diffusion weighted imaging and apparent diffusion coefficient (ADC) in diagnosing acute biliary pancreatitis.Methods:MRI was performed with routine sequences and diffusion weighted imaging on 12 patients with acute biliary pancreatitis,17 patients with obstructive jaundice and 15 normal subject.We measured the pancreas’ADC values of the acceptable images after assessed the quality of [...]
