Clinical Department & Center

Diagnostic and Interventional Radiology


Diagnostic and Interventional Radiology may be an unfamiliar clinical department among patients, but it is actually engaged in very important work. Our department cooperates with all other clinical departments to play a role in improving the level of medical care in the entire hospital. We use CT and MRI images to diagnose patients’ diseases, and are actively involved in angiography and its procedure for the treatment of diseases.


Medical care system

We are involved in the creation of diagnostic reports on most CT and MRI scans that are performed in the hospital (numbers of scans taken in FY 2010: CT: 32,435, MRI: 15,404), angiography as well as treatment involving the application of angiography during the procedure (IVR) (number of these procedures in FY 2010: 1,009).  

Treatment policy

With the motto “accurate and quick diagnostic imaging,” we maintain a system of reporting the results on the same day or within two days using our imaging network. Regarding angiography, we are on standby for embolization and other urgent procedures around the clock.

Areas of medical care

As mentioned above, out department is largely divided into two sections.
Diagnosis section (diagnostic imaging): creation of reports on diagnostic CT and MRI scan images of the whole body
Angiography/IVR section: angiography and treatment using the procedure (IVR)
We provide medical care mainly in the following specialized areas.
  • Artery embolization for hepatoma and hepatic metastasis (transcatheter arterial chemoembolization)
  • Percutaneous catheter placement for hepatic arterial infusion
  • Artery embolization for multicystic kidney and polycystic liver
  • Uterine artery embolization (UAE)
  • Renal artery embolization
  • Splenic artery embolization
  • Percutaneous variceal embolization
  • Vascular malformations (arteriovenous malformation, arteriovenous fistula) ・Arterial embolization for visceral arterial aneurysms
  • Percutaneous radiofrequency ablation (RFA) for renal and lung tumors
  • Arterial injection chemotherapy for head and neck tumors
  • Percutaneous drainage
  • Preoperative portal vein embolization
  • Percutaneous needle biopsy
  • Implantable central venous access port
  • Inferior vena cava filter placement

Consultation hours

First-visit/return-visit reception at the angiography/IVR clinic: 8:30 a.m. – noon on Tuesdays, Wednesdays and Fridays
First-visit patients are kindly requested to make an appointment through the Community Service and Welfare Network of our hospital. Patients without an appointment will wait longer.

Major tests and equipment

Three multislice CT scanners (latest 320-slice CT, 80-slice CT, 64-slice CT), one MRI scanner (3.0T), four MRI scanners (1.5T) (it is planned to replace with a 3.0T MRI), three angiography systems (of which, two systems have the capability to perform rotational DSA. One has a CT scanner for angiography (IVR-CT))

Medical care results

Diagnosis section: reading of images of most CT and MRI scans performed in the hospital, and the creation of diagnostic reports
Angiography/IVR section: annual number of cases: approx. 1,000
