[Methods] Collected and analyzed to the spiral CT dynamic enhancement findings and it's routine scan findings of 30 lung cancer nodule cases,observe the CT values of the primary affection in each time,and draw dynamic enhancement time-density curves.

Objective To study the relationship between MSCT peak dynamic enhancement ratio in arterial phase and the grade of cell differentiation,MVD,VEGF,CD34 expressions of HCC, and to evaluate the tumor angiogenesis in hepatocellular carcinoma and provide a foundation to treatment and predicting prognosis of HCC.

All cases were performed dynamic enhancement scanning on 3.

MRI with multiple contrast weightings and dynamic contrast enhancement in evaluation of vulnerable atherosclerotic plaques;

Dynamic contrast-enhanced MRI of breast disease: correlation of MR findings with vascular endothelial growth factor and microvessel density;

Value of DWI and dynamic contrast-enhanced MRI in differential diagnosis of lymph node lesions

Objective To evaluate the role of conventional spin echo(SE) and dynamic contrast-enhanced(DCE) MR imaging with high magnetic field in renal cell carcinoma(RCC) in comparison with helical CT.
