Image Characteristics and Value of 1.5T MRI in the Staging of Cervical Cancer
Main Article Content
Abstract
A prospective descriptive study of 56 cervical cancer patients, were taken 1.5T MRI before surgery, and has result pathology after surgery in the hospital K.
Results: The min and max ages are 25 and 68, the average age is 45.3 ± 10.4. Squamous-cell carcinoma 76.8%, Adenocarcinoma 17.9%. 98.2% mass shows a slightly hyperintense in T2-weighted MR image, 89,3% shows a isointense in T1W, 83.9% shows a hyperintense in Diffusion (b800), 75.0% T1FS-weighted MR image shows poorly absorbed drugs for muscle fiber uterus after injection, 53.6% heterogeneous infiltration strong enhancement of the tumor. Assess tumor size has Acc and PPV 94.6%. The rating invasive vaginal has Sn 66.7%, Sp 100%, Acc 98.2%, PPV 100% and NPV 98.1%. Invasive parametre has Sn, Sp, Acc, PPV and NPV 100%. Invasive sides pelvis has Sp 100%, Acc and NPV 98.2%. Diagnosed lymph node metastases with Sn 50%, Sp 97.8%, Acc 89.3%, PPV 89.3% and NPV 90.0%. Staging of the MRI 1.5T has Acc and PPV 91.1%.
Conclusion: Image 1.5T MRI on observable clarity T2WI, DWI before the injection and T1FS after the injection contract. 1.5T MRI has high value for staging Cervical cancer. MRI should be used routinely for staging Cervical cancer.
