What does kidney cancer do CT examination

summary

Renal cancer is a familiar disease. So many people will fear that this disease will happen in their own body, after the emergence of this disease, accept professional CT examination, to avoid aggravating the disease, then, what CT examination for renal cancer, let's take a specific look at it.

What does kidney cancer do CT examination

First, CT examination can clearly show the renal parenchymal mass with a diameter of more than 1cm, which is of great value in the differential diagnosis of renal space occupying lesions, namely cystic and solid space occupying lesions, with an accuracy rate of 93%.

Second, the CT images of renal cell carcinoma are as follows: ① the edge of the tumor is irregular, round or lobulated. ② The density of clear cell carcinoma was lower than that of normal renal tissue. The density of granular cell carcinoma was higher than that of normal. ③ In contrast-enhanced scan, the tumor density was enhanced in different degrees. But it was still lower than that of normal renal tissue. As the density difference between the tumor and the tissue increases after contrast enhancement, the size and boundary of the tumor can be clearly displayed. ④ There are often hemorrhage, liquefaction and necrosis areas in the tumor, which make the tumor density uneven. A few calcification foci with enhanced density were found in the tumor or its edge. ⑤ CT can accurately measure the scope and size of renal cell carcinoma lesions, and can also understand whether there is infiltration and lymph node metastasis around the kidney, so as to provide the basis for the staging of renal cell carcinoma. ⑥ Cystic renal cell carcinoma, which is similar to the image of renal cyst, is easy to be misdiagnosed. However, cystic renal cell carcinoma has thicker cyst wall and higher CT value of cystic fluid than that in renal cyst.

Third, CT is more accurate in the clinical staging of renal cell carcinoma. Compared with the pathological results, the accuracy of CT is 77.8% and 95.6% respectively. The staging criteria are based on the following aspects: whether the mass is limited in the renal capsule, whether it is limited in the renal fat sac, whether there is venous invasion, lymph node metastasis, adjacent organ invasion and renal pelvis invasion.

matters needing attention

Early tumor diet, early tumor Qi and blood injury, yin and yang imbalance, should regulate Yin and Yang, Yiqi Yangxue. In addition to the above foods, we can choose a series of kidney cancer diets such as peach ginseng soup, tremella soup and nut paste. Eat protein rich foods, such as milk, soybean milk, mashed potatoes, green beans, spinach, fish soup and other kidney cancer diet, can also be used medlar fried meat. But pay attention to food should not be eaten, too full.
