Resting electrocardiogram (EKG)

Electrodes are attached to your wrists, ankles, and chest, and the electric signals from the heart are recorded. Electricity is not sent through the body, so there is no paralysis or pain. The examination is performed while lying on a bed and resting, and is finished in a few minutes. Arrhythmia, cardiac hypertrophy, cardiac infarctions, and other heart diseases can be discovered with this examination.

Lung capacity, forced expiratory volume in one second, forced expiratory volume one second percent

By breathing in and out through a mouthpiece, we can examine your lung functions. There is no pain, but you must be able to make your best effort during the examination. The capacity of your lungs and forced vital capacity are measured, and diseases of the lungs and air duct can be found through this examination.

PET stands for Positron Emission Tomography.

A medicine is injected into a vein in your arm to expel the positrons (protons) in your body, and the way the medicine collects in parts of your body is seen through a special camera. CT scans are done in the same way. PET and CT scans typically scan the area from around your ears all the way to your ankles. PET/CT machines create 2 images at roughly the same time, and a high-quality image that is valuable for diagnosis can be created through combined both images.

For our PET/CT scans, we inject fluorodeoxyglucose (FDG), a medicine that labels fluorine-18 (18 F) radioactive isotopes, which collects in places such as cancer cells that consume large amounts of glucose, which allows us to see if cancer is present or not. Cancerous cells require 3 to 8 times the glucose compared to normal cells.

The medicine also collects in pneumonia and abscesses (an area filled with pus), so a collection of medicine does not necessarily mean cancer.

1. The Power to Discover Early-Stage Cancer
   These scans create an image that finely cuts the body into round sections. Each section is only 3.3 mm thick, and it is thought that malignant cancer can be found at 5 mm or more. These scans are also useful in discovering spreading or reoccurring cancer.
    


2. The Whole Body Can Be Scanned in a Single Examination
   Up until recently, CT, MRI, or scintigraphy had to be chosen based on the location in the body (organs). But with PET/CT scans, almost the entire body can be checked for cancer in a single examination.
    


3. Useful in Identifying Benign or Malignant
   PET/CT scans can better determine whether a tumor is benign or malignant in cases where CT, etc., cannot be sure. This is because PET/CT scans determine how much of the medicine used collects in the lesion areas using numbers.
    
4. Minimal Pain
   The only pain with this examination is the pain from the injection, after which the patient only needs to lie still and rest. There is no need for taking Valium or having cameras inserted in your body.

Upper endoscopy (ultrasound examination: liver, bile duct, renal gland, spleen, and pancreas)

(An upper endoscopy examines the liver, bile duct, renal gland, spleen, and pancreas.

If food remains in the stomach, this causes bowel movements and gas buildup, leading to an ineffective examination. This examination requires fasting at breakfast on the day of the examination.

A lubricant jelly is applied to the stomach, and moving the device around, the liver, bile duct, renal gland, spleen, and pancreas are examined, checking for cancer, polyps, or any other lesions.

Obesity can sometimes prevent the pancreas from being examined.)
