What are the advantages of CT in diagnosing kidney cancer, and what are the CT manifestations of ren

Kidney cancer and liver cancer are both malignant tumors with rich blood supply, and their CT enhanced scans are characterized by "fast in and fast out" performance, for this characteristic sign, kidney cancer is more likely, and the diagnosis still depends on pathology.

CT findings of renal cell carcinoma are: abnormal renal outline, local bulge and protrusion, and mass lesions in the renal parenchyma. The shape of the lump is round, oval, or irregularly lobulated.

Most lesions have unclear borders, and some lesions have clear borders and appear as smooth and sharp round-like masses. The density is slightly lower than or close to normal renal parenchymal density on noncontrast scanning, and the density is uniform. If there is hemorrhage and necrosis in the tumor, the density of the tumor is uneven, and if there is pure calcification of orange, it can be scattered irregular nodules or arc-shaped and incomplete annular calcifications around the tumor.

The enhancement of the normal renal parenchyma was obvious, but the enhancement of the tumor area was not obvious, and the enhancement of the tumor in the cortical stage of the spiral CT enhancement scan was obvious. Perrenal spread is manifested by blurred tumor margins, thickening of renal fascia, disappearance of perirenal fat sac, invasion of psoas muscle, and bone destruction of lumbar vertebrae. CT of lymph node metastases may show enlargement of perirenal, inferior vena cava, and para-aortic or diaphragmatic lymph nodes.

Magnetic resonance imaging is better for the diagnosis of BAI small kidney cancer.

However, there is no allergy to X-ray radiation or DAO contrast medium. Magneto-common.

It has a high resolution of vibration on soft tissues, which can distinguish high-density cysts from renal cancer, and has certain advantages in the qualitative subtype of pathological histology, so it is an imaging diagnostic method of choice for patients with renal insufficiency and contrast allergy. For small renal masses that are difficult to diagnose with contrast-enhanced CT, the use of a more sensitive dynamic enhanced MRI of fat suppression is of differential diagnostic significance.

In addition, for kidney cancer patients, as an adjunct, you can also take red ginseng, Jinxing (ginsenoside rh2) capsules, cordyceps sinensis and other traditional Chinese medicines that can nourish vitality according to your own situation, improve immunity, enhance the first effect, reduce the pain of patients, prevent ** and metastasis, and at the same time let patients have a strong appetite and physical recovery, which can effectively improve the quality of life.

Renal cancers are slightly less dense than the renal parenchyma, but are very close, so smaller tumor lesions tend to be missed on noncontrast scanning. After contrast-enhanced scanning, the density of renal cancer lesions was slightly enhanced, while the density of normal renal parenchyma was significantly enhanced.

Kidney cancer can be diagnosed because there are many necrotic lesions of varying degrees, hemorrhage, cystic changes and even calcifications.

Nowadays, people eat well and are more nutritious, and the incidence of kidney cancer is on the rise, and the vast majority of patients are only found during physical examinations without any symptoms. How to prevent kidney cancer, we need to avoid risk factors for kidney cancer, such as smoking, obesity, high blood pressure, exposure to radiation, drug abuse, and exposure to toxic and harmful gases, such as chemical raw materials. Secondly, it is necessary to strengthen personal physical exercise, exercise appropriately, improve one's own immunity, and at the same time eat a reasonable diet and eat more vegetables and fruits.

Common clinical manifestations: ** intermittent episodes with macroscopic hematuria, low back pain, abdominal mass, and other systemic symptoms such as fatigue, weight loss, loss of appetite, anemia, cough, and hemoptysis. and manifestations such as polycythemia, hypertension, and fever.

The symptoms are different depending on the stage, and if it is early-stage kidney cancer, most patients will not have obvious symptoms. In the middle and late stages, there will be a typical triad of abdominal pain, abdominal mass, hematuria, and some patients may have metastatic symptoms and cachexia.

Diagnosing kidney cancer requires laboratory tests, imaging tests, and pathological tests. The purpose of laboratory examination is to evaluate the patient's preoperative general condition, liver and kidney function and prognosis, mainly including urea nitrogen, creatinine, liver function, complete blood count, hemoglobin, blood calcium, blood glucose, erythrocyte sedimentation rate, alkaline phosphatase and lactate dehydrogenase. Currently, there is no recognized tumor marker that can be used for the clinical diagnosis of kidney cancer.

The clinical diagnosis of kidney cancer is mainly based on imaging tests, and the diagnosis is confirmed by pathological examination.

Commonly used imaging tests include: chest x-ray (anterior and lateral), abdominal ultrasound, abdominal CT, abdominal MRI, PET or PET-CT are rarely used to diagnose kidney cancer, but are mostly used in patients with advanced kidney cancer to detect distant metastases or to evaluate the efficacy of chemotherapy, molecularly targeted** or radiotherapy. Patients who are unable to evaluate contralateral renal function without CT scan should have a radioclide renal flow map or intravenous urography.

Patients with kidney cancer who have one of the following three elements should have a radioclide bone scintigraphy:

1.There are corresponding bone symptoms.

2.Alkaline phosphatase is high.

3.Clinical stage. A chest CT scan should be performed in patients with renal cancer who have suspicious nodules in the lungs on chest x-ray or who are clinically staged. Patients with kidney cancer who have headache or neurological symptoms should also have a head MRI and CT scan.

Because the coincidence rate of imaging examination in the diagnosis of kidney cancer is as high as more than 90%, and the value of renal biopsy pathological examination in diagnosing kidney cancer is limited, renal biopsy is usually not done. However, for patients with small tumors whose nature is difficult to determine by imaging diagnosis, nephron-sparing surgery or regular (1 to 3 months) follow-up examinations can be selected. For patients with kidney cancer who are elderly and frail or have contraindications to surgery, or patients with inoperable advanced kidney cancer who require energy ablation** (such as radiofrequency ablation, cryoablation, etc.) or chemotherapy, kidney biopsy can be selected to obtain pathological diagnosis before the diagnosis is confirmed.

Hello, I would like to introduce you to the following 6 diagnostic methods for kidney cancer, for your reference:

1. Urine routine examination: when the cancer invades the renal pelvis and renal calyces, there are different numbers of red blood cells in the urine routine examination; However, a completely normal urinalysis does not rule out a kidney tumor.

2. X-ray examination: It is a very important method for diagnosing kidney tumors, and with the continuous update of equipment and technology, the accuracy of X-ray examination is also significantly improved.

3. CT examination: It is mainly used to diagnose renal space-occupying lesions, and the accuracy rate of the identification of cystic and parenchymal masses reaches 93%.

4. MRI examination: MRI can clearly show the renal parenchymal mass and distinguish it from the renal cyst.

5. Ultrasound diagnosis: B-mode ultrasound imaging is one of the important methods for diagnosing kidney tumors in recent years, and it has been widely used in the diagnosis of kidney tumors because of its simple and non-invasive ultrasound examination methods. Therefore, it is helpful for the clinical staging of kidney cancer.

6. Radionuclide examination: Radionuclide examination is of great value to the understanding of organ function, and can also use imaging technology to reflect the function of the organ and show the shape of the organ.

The last time I watched CCTV news, the curative effect of biological ** kidney cancer in 307 Hospital is good, it is recommended to learn more!

The early signs of kidney cancer are about 50% and 75% of patients are manifested in symptoms other than the urinary system, such as fatigue, lack of energy, poor appetite, indigestion, nausea, constipation, fever, weight loss, anemia, liver dysfunction, gastrointestinal dysfunction, hypertension, hypoglycemia, etc.; These symptoms tend to precede the onset of urinary symptoms, such as fever and hematuria by 2 to 6 months. These early symptoms are often overlooked. and other intrarenal symptoms, such as:

When the three major symptoms of hematuria, pain and lump are concerned, the general course of the disease is mostly advanced; Generally, in the earlier stages, there are only one or two of them.

As the second leading cause of urological cancer, kidney cancer is a serious threat to people's lives and quality of life. In addition to acting on cancer cells, traditional anti-cancer** can also affect normal cells, often leading to serious adverse reactions that people do not want to see. "Identifying and directly attacking carcinogenic products" has been a core concept that has driven cancer research for more than a decade.

The emergence of Fuzheng Fang for Kong's kidney cancer is undoubtedly a new breakthrough and new progress for advanced kidney cancer. It can not only inhibit and kill cancer cells, but also cooperate with surgery, radiotherapy and chemotherapy to effectively prevent the metastasis of cancer cells. Its anti-vascular efficiency is about 60% higher than that of radiotherapy and chemotherapy, coupled with its control of lesions, so that patients with tumors can reach about 75%-90%.
