There are two MRI scanners at Aizawa Hospital. MRI is an equipment to examine the suspicious lesion from every direction, for example, vertically, horizontally and diagonally, using strong magnetic field. MRI is the most suitable for imaging of cerebral blood vessels. It can provide clear images without contrast agents. MRI does not use radiation either, therefore there is no need to worry about radiation exposure.

We have a 320-slice CT scanner and two 64-slice CT scanners. CT is equipment to produce cross-sectional images of the body using X ray. 320-slice CT scanner has the newest technology, Area Detector Technology, which enables to scan the whole blood vessels of the moving heart in a split second with radiation exposure reduced by 75% at the maximum. By taking advantage of one of the CT's characteristics which enables producing serial images in a short period of time, CT can provide chronological three dimensional images similar to cerebral angiograms. Therefore, CT is perfect for a diagnosis of cerebrovascular diseases or circulatory system conditions.

We have two PET-CT scanners. While conventional diagnostic equipment such as CT and MRI detects tumors by the change of morphology, PET-CT visualize the active state of the cells to detect small cancer cells with the size of about 1 cm. PET-CT scan requires administration of radioactive agent, however, radiation exposure is about the same amount as a barium examination of the stomach. Radioactive substances are reduced by half after 2 hours from administration, and also excreted in the urine. On the next day, almost none remain in the body.

Angiography equipment is equipment to provide images of selected blood vessels by inserting a catheter and injecting contrast agents. In addition, this equipment is also used to widen cardiac blood vessels narrowed with blood clots, close off the blood vessels to stop bleeding in the stomach, and perform intravascular treatment such as treatment for cerebral aneurysm or cerebrovascular anomaly. Our angiography equipment can perform rotational angiography, which produces 3D images and cross-sectional images as CT scan.

Proton therapy is a type of radiotherapy, which reduces radiation dose to healthy tissue and more effectively radiates the tumor compared to the conventional radiation therapy which uses x-rays. Therefore, proton therapy is known as radiotherapy for cancer which is less harmful to the body. Please go to “Proton Therapy page” for more information.

Gamma knife is radiotherapy equipment which radiates a lesion in the brain from every direction with high precision using high-dose gamma ray. Gamma knife enables treating abnormalities inside the brain or functional brain disorder without a surgical procedure. Since Gamma knife is designed for noninvasive treatment, precision of pinpoint radiation, high efficiency and great treatment effect can be expected.

TomoTherapy is equipment combines intensity modulated radiation therapy (IMRT) and image guided radiation therapy (IGRT) to irradiate only the appropriate site with the appropriate radiation dose.

There are 6 Endoscopy Rooms in Aizawa Hospital. We perform upper/lower gastrointestinal endoscopy to over 50 patients a day. Endoscopic treatments such as polypectomy are also performed.

There are 72 dialysis machines in the Dialysis Center. We perform 2 courses of dialysis treatment a day. Since dialysis takes hours, we pay much attention to keep the environment comfortable for patients.

There are 8 Operating Theaters in Aizawa Hospital. We have established a management system, which includes staffing of anesthesiologists, to provide surgeries (scheduled / emergency surgery) for various injuries and diseases 24 hours a day. Meanwhile, we are dedicated to safety management and preventing complications such as surgical site infections.

There are 24 Chemotherapy rooms (booths) in the Comprehensive Cancer Center. Patients can receive chemotherapy on the bed or reclining chair depending on their condition.

Recent studies show that one out of two Japanese people develop a cancer, and cancer has become the number one cause of death in Japan. Accordingly, to meet increasing cancer care needs, Aizawa Hospital is putting great effort into cancer care. In 2007, we established Aizawa Comprehensive Cancer Center and organized a system to propose and provide the most suitable cancer care for each patient’s needs, including chemotherapy, radiotherapy, surgical therapy and palliative care. Aizawa Hospital has been designated as a Cancer care district liaison hospital by the Japanese Ministry of Health, Labor and Welfare since 2008.

Aizawa Hospital has established the Emergency and Critical Care Center in 2002 to accept patients 24 hours a day, 7 days a week. We improve staffing of emergency physicians and nurses at the Center to provide care for various types of diseases or injuries. Over 45,000 patients receive medical care at our Center every year.

We provide early rehabilitation services along with acute treatments to enhance patients' functional recovery and to help patients go back to their everyday life as soon as possible.
