| MRI of Percutaneous radiofrequency ablation for hepatocellular carcinoma evaluation
Would generate 80100 ℃ high temperature, can effectively kill tumor cells quickly, while allowing the blood vessels around the tumor tissue coagulation with, and prevent tumor metastasis to achieve the purpose of treatment. 3.2 MRI evaluation of ultrasound, color Doppler, and enhanced helical CT scan can be used for treatment of hepatocellular carcinoma after radiofrequency ablation efficacy evaluation of ..., but ultrasound can not be identified residual tumor; color Doppler to the tumor observation of blood flow within the dynamic,mbt scarpe, but the display rate of lesions is limited; spiral CT enhanced scan can not properly evaluate changes in the edge of early lesions. MRI anatomy is not only a good display capabilities, and the ability to distinguish good organization. Especially after local tissue injury in the existence of hemorrhage, hemosiderin change, and determine whether there is local edema plays an important role. After radiofrequency ablation of liver cancer, early and late B [u check damage foci can be a good show changes in the lesion showed the typical changes in three concentric circles. (1) inner: the destruction of damage to kitchen center, T1WI and T2WI showed high signal in the electrode damage caused bleeding area. (2) second layer: T1WI and T2WI showed low signal targeting coagulation necrosis. (3) The third layer: in the T1WI showed low signal, T2WI showed high signal, which is after the edema target damage. Kraum [7] that the size of edema volume associated with the middle layer. We analyzed 48 cases of liver cancer patients in this group after the MRI performance, display size varied from small center, but the frequency of the dose differences in the Q layer has a significant change in size. Patients with large diameter middle layer, the edema is more evident positive correlation between the two (P> 0.05). Because the electrode damage, cell necrosis, hemorrhage, and 12 thus Tlw high signal. The size of radiofrequency catheter ablation has nothing to do when the amount of disposable saliva. The second layer is the middle layer in the T1WI showed low signal or other signals, and then showed low signal in T2WI. After treatment with radiofrequency coagulation necrosis of liver cells, proteins, and the related emergence of hemosiderin. Destruction of tumor size tumor is to determine the most appropriate sign. The effect size significantly correlated with the patients. 3.3 The efficacy of radiofrequency ablation for hepatocellular carcinoma radiofrequency ablation of liver Volume 5, No. 4 Hospital of Chengdu Military Region, Vo1.5. No. 42003 on August HospitalJoumalofChengduMilitaryCommandAugust. 2003 Inflammatory pseudotumor of the lung misdiagnosed as lung abscess in 1 case were Yan Li Zhang Yalin, male, 50 years old; in February because of cough, fever more than a month, bloody sputum 5 Japanese hospital. Examination: T37.7oC, P80 times / min, BP120 /, 75 duh, right lung could be heard and scattered in the wet 哕 tone. Chest X-ray showed: lower lobe of right lung lesions associated with infection, CT see after the lower lobe of right lung about the size of the basal segment 7em × 4em × 3em heterogeneous high density, edge rough. PPD-negative,adidas scarpe, ESR 12mm / h, normal blood, sputum pus ball routine, 8-12,ugg boots italia, 0-1 red blood cells, epithelial 0-2; bronchoscopy see a lot of right lower lobe bronchus opening yellow-green purulent sputum, to give local irrigation , and attract injection treatment of suspected right lung after bronchoscopy under the dorsal segmental bronchus lung abscess. CT-guided biopsy pathology as Discussion of inflammatory myofibroblastic tumor, also known as inflammatory pseudotumor, according to reports, common in the lung or pulmonary many internal parts are also found in the abdominal cavity, mesentery and retroperitoneum, etc., the mass can be large and small, gray, a single unit of : General Hospital of Chengdu Military Region, Department of Respiratory Medicine,GHD glätteisen, Kunming (Kunming 650o32) short case or multiple nodules, the right lung than the left lung, boundaries more clearly, but no capsule. Variety of histological features, from the proliferation of fibroblasts and myofibroblasts form, and sometimes that kind of granulation tissue or collagen fasciitis of the structure and a large area, a large number of tumor tissues scattered inflammatory cells, when co-infection, the next chest x line and the CT examination often show diverse tumor lesion center liquefaction, necrosis and collagen of the time, there may be large and liquid-gas surface hollow cavity, often easy and lung abscess, tuberculosis cavity, lung cancer or teratoma formation relative to empty confusion, CT puncture the patients were finally diagnosed. Preoperative diagnosis of the disease more difficult,puma, very difficult to identify with lung abscess, we believe that unexplained pulmonary cavities not satisfied by the general anti-inflammatory treatment, and patients over 40 years of age, biopsy should be a positive line, if necessary, surgery.
