CHECK-UP

(1) Use of barium contrast agent: This method is used to check and diagnose organs such as esophagus, stomach, small intestine, and large intestine. There is also a contrast agent injected with special drugs in the blood vessels. Through the liver, the bile ducts or gallbladder can be contrasted, and the kidney, urethra, and bladder can also be contrasted.

(2) Angiography method: directly illuminate the presence of lesions in veins or arteries. This method is commonly used for brain cancer or lesions of the pancreas and liver. Cerebral arterial photography has obvious effects when examining diseases such as tumors and subarachnoid hemorrhage.

(3) Lu Guangzhong’s method is tomography. Divide a part of the body into a certain segment for dimming tomography. For example: tomography for tuberculosis, 1 cm or 0.5 cm thickness, tomography of the lung.

(4) CT (computer tomography) diagnosis: This method is used for diagnosis of brain, liver, pancreas, etc.

Gastroscopy is the most representative method of examining the stomach, and its advantages are that it is widely used clinically while observing and taking pictures.

Ultrasound diagnosis uses short sound waves (ultrasonic waves) to penetrate soft tissue parts. When such sound waves hit the body, if there are hard pieces in the soft tissue, they will be reflected back. During a breast examination, ultrasound is sent to the soft mass of the breast, and it will go out from the other side of the body through the soft mass, and it will reflect back when it encounters hard cell groups such as cancer.

Cytological diagnosis is generally performed in conjunction with endoscopy. Because the diagnosis is performed by inserting special instruments in the visible range of the naked eye and removing some cells for diagnostic purposes, endoscopy is indispensable. The most common and simple is the cellular diagnosis of uterine cancer. This type of cancer can be seen with the naked eye, and the use of instruments to take cells from the problematic site has greatly improved the early detection rate of uterine cancer.

Blood biochemical diagnosis

The method of diagnosing cancer by blood chemistry is generally only used for male prostate cancer examination. The abnormal increase in acid phosphatase in the blood can be diagnosed as cancer, which is a method with high reliability and reliability.

PET-CT perfectly integrates PET and CT. PET provides detailed molecular and other molecular information about the lesion, while CT provides precise anatomical positioning of the lesion. One-time imaging can obtain tomographic images of all parts of the body, which is sensitive and accurate. , Specific and accurate positioning, etc., can understand the overall status of the whole body at a glance, to achieve the purpose of early detection of lesions and diagnosis of diseases.

CTC circulating tumor cell detection

The detection of circulating tumor cells can be effectively applied to early in vitro diagnosis, rapid evaluation of chemotherapeutic drugs, and personalized treatment including clinical screening drugs, detection of drug resistance, monitoring of tumor recurrence, and development of new tumor drugs. This technology has been developed and matured in swiss
