Advice for Common Diseases 

lifestyle disease

Lifestyle-related diseases such as hypertension, diabetes, and dyslipidemia progress arteriosclerosis in blood vessels throughout the body, increasing the risk of serious attacks such as stroke or myocardial infarction one day.

In particular, when multiple diseases or metabolic syndrome with obesity are present, arteriosclerosis is likely to progress even if the respective test values are not so bad. 
If lifestyle-related diseases are indicated in health checkups or other medical examinations, it is important to make sure to see a doctor, receive appropriate treatment, and keep the numbers under control. 
We recommend head MRI examinations for those who have lifestyle-related diseases, have blood relatives who have developed cerebrovascular disorders, have been indicated as requiring close examination during physical examinations, or have concerns about the condition of their cerebrovascular system. 


Blood pressure levels are maintained above the normal range, which continues to place a heavy burden on the blood vessels and causes arteriosclerosis to develop. 
Causes include excessive salt intake, obesity, stress, heredity, and aging blood vessels. 
Please do not think that it is okay if it is a little high, but see a doctor as soon as you notice that your blood pressure is high. 

Dyslipidemia (hyperlipidemia)

Dyslipidemia (hyperlipidemia) is a condition in which the amount of bad cholesterol (LDL) and triglycerides (TG) in the blood is high or the amount of good cholesterol is low. 
Lipid components tend to accumulate in blood vessels, leading to progressive arteriosclerosis and increased risk of cerebral infarction, cerebral hemorrhage, subarachnoid hemorrhage, angina pectoris, myocardial infarction, etc.

Dyslipidemia has few subjective symptoms and requires attention 

Diabetes Mellitus

Diabetes mellitus is a disease in which there is an excess of sugar in the blood, resulting in high blood glucose levels. It develops when there is a lack of insulin, which is responsible for maintaining a constant blood sugar level, or when its function is weakened. 
Diabetes not only increases the risk of stroke, cerebral hemorrhage, and subarachnoid hemorrhage by progressing atherosclerosis, but also has a number of complications that can cause serious symptoms such as blindness, kidney failure requiring dialysis, and necrosis of the legs. 
It is important to start appropriate treatment as early as possible and to control the disease well. 

If your health checkup indicates that you need to be re-examined or need closer examination

If you receive a medical checkup that indicates lifestyle-related diseases or metabolic syndrome, or if you are recommended to undergo a reexamination or a detailed examination, it is possible that arteriosclerosis has already progressed. 
For early detection of brain diseases and accurate prevention by knowing the risks, we recommend a detailed examination of brain diseases and cerebrovascular system by MRI scan.

Colorectal cancer screening (age 40 and over) 

Colorectal cancer begins to increase in people in their 40s and is the leading cause of cancer death in women and the second leading cause in men.
In the colorectal cancer screening in Machida City, two days’ worth of stool samples are collected and examined. Because colorectal diseases such as cancer and polyps can cause bleeding in the colon, a small amount of blood in the stool is examined.
Colorectal cancer can be detected at an early stage through screening, and if detected early, the cancer can be more likely to be completely removed.

The program is available to residents of Machida City who are 40 years of age or older and who have not had the opportunity to undergo colorectal cancer screening at work or other places. 

lung cancer screening 

Lung cancer tends to be more common in males and begins to increase rapidly around age 60, becoming more common the older a person gets. It is the second most common cancer in men and women combined. 
Lung cancer screening in Machida City is a chest X-ray examination. The entire chest is radiated with X-rays to examine the lungs for shadows suspicious of cancer. 
Lung cancer in its early stages has no subjective symptoms and is rarely detected without medical screening. If detected early, it is a cancer with a high survival rate. 
The screening is available to residents of Machida City who are 40 years of age or older and who have not had a lung cancer screening at their workplace. 

About MRI Examination 

MRI scans use a strong magnet and radio waves to examine conditions inside the body. 
These radio waves, like those used in radios, and the magnetic fields created by the magnets shake the hydrogen atoms in the body. 
By making images of this situation, the state of water and blood flow in the body can be checked in detail.

Since no X-rays are used, there is no risk of radiation exposure and it is safe. It is also useful in detecting various diseases since it can monitor the condition of blood vessels, brain, spine, limbs, joints, etc. 
This test is especially essential to determine the presence of atrophy or tumors in brain tissue and the condition of cerebral blood vessels. 

MRA test

The MRA test is used to delineate blood vessels in the brain and determine the risk of cerebrovascular disease.

The test checks for stenosis or blockage of arteries in the brain from the carotid arteries and detects cerebral aneurysms that can cause subarachnoid hemorrhage. 
Catheterization or other treatment before rupture can prevent serious subarachnoid hemorrhage. It is also useful for early detection of cerebral infarction, cerebral arteriovenous malformation, moyamoya disease, and occlusive arterial lesions. 

Test results will be explained by the director on the day of the test. 

The director, who has built up a long career as a specialist in neurosurgery, explains the results in an easy-to-understand manner on the same day while viewing the test images. 

carotid artery ultrasound 

The carotid artery is an important artery that carries blood to the brain, and atherosclerosis causes the walls of the artery to thicken and the vessel to narrow due to plaque and thrombus. 
If left untreated, this can cause a stroke. 
Tomographic imaging by echography reveals the thickness of blood vessel walls, the condition of the inside of blood vessels, and how blood flows. 
Echocardiography (ultrasound) is a gentle examination that does not expose the patient to radiation. The patient lies on his/her back and an instrument called probe with jelly is applied to the examination site for observation. The examination takes about 15 minutes.
