This test has attracted attention in recent years for its ability to detect even small cancerous growths, and its ability to check the whole body in one test with a minimum of discomfort.It is possible to check the whole body in one test with a minimum of pain or other discomfort.
＜Recommendations for cancer PET scans＞
Anyone who is (1) middle-aged, in particular aged 50 and above; (2) has close relatives who have contracted cancer, or (3) where smoking or other cancer risk factors are present. Even if only one of the factors applies, the recommendation is to undergo a PET scan once a year, or every other year.
Since PET scans are not good at everything, it is best to conduct scans in combination with a CT, MRI, or ultrasound, rather than a PET scan on its own.
This scan uses x-rays to produce cross-sectional pictures of the body. The scan permits the discovery of a range of lesions inside the body, but in particular, it is known for superior rendering of pathological changes in the chest area, including the heart, the aorta, the bronchial tube and the lungs, and the abdominal area, including the liver and the kidneys.
This is an excellent diagnostic imaging apparatus that is useful for detection of cancer etc. PET-CT integrates CT device into PET device. While CT pictures have been mainly used to find abnormalities of form, such as size and shape of organs, to detect foci, PET pictures are used to find differences of activity level of cells (metabolism). PET diagnosis is therefore able to detect lesions which conventional imaging methods cannot find.
This scan uses magnetism to produce images of the internal organs and the blood vessels by passing the body through a tube that contains a series of powerful magnets. The scan is capable of detecting a range of lesions, but in particular, it is known for superior rendering of pathological changes that may occur in the brain, the spine, the limbs as well as the uterus, the ovaries, the prostate gland and other areas of the pelvic cavity.
The scan cause no radiation exposure, and it is also able to produce cross-sectional pictures of the inner brain and the spine which are difficult to obtain with CT scan.
PET-MRI scan provides both difference in the activity level of cells (metabolism), which the PET scan produces and pictures of organs and blood vessels which MRI scan produces. One time test with PET-MRI scan provides test results which have been able to be obtained only with two separate tests so far.
An upper (gastro) endoscope is medical equipment to observe, deal with, and treat if necessary, lesions inside of the body that cannot be seen from outside by inserting a tube attached a lens at the top of it. The tube of an upper endoscope is inserted through mouth (or nose) to inspect mainly the esophagus and the stomach. The tube of a lower endoscope is inserted through the anus to inspect mainly the large bowel.
This is a colon examination method using CT instead of an endoscope. It is said that 3D-CT colonography causes generally less pain compared to an examination with an endoscope, and although the patient has to start eating special diets from the day before the test, 3D-CT takes short time to complete (about 15 minutes).
This treatment is a radiotherapy for cancer tumors using heavy particles (carbon ions). Among radioactive rays, rays heavier than electrons are called particular beams, and rays heavier than helium ion beams are called heavy particle beams. Heavy particle radiotherapy is radiotherapy that uses the heavy particle (carbon ion) beam.
