Main Areas and Themes of Research

1. Medical Imaging Diagnosis
a) Clinical Research:

Hepatobiliary and genitourinary imaging

  1. Kinetic evaluation of regional liver perfusion using multiphasic dynamic MRI and CT
  2. Analysis of blood flow of the hepatic artery and portal vein by MRI and CT perfusion imaging of the liver
  3. Evaluation of both quantification of the portal vein blood flow and heterogeneity of the intrahepatic local blood flow by BOLD fMRI
  4. Evaluation of hepatic function and liver fibrosis by contrast-enhanced MRI using liver-specific contrast agent (Gd-EOB-DTPA)
  5. Assessment of extrahepatic solid organ fibrosis in patients with liver cirrhosis by diffusion-weighted imaging (DWI)
  6. Assessment of liver fibrosis by MR elastography with echo-planar imaging
  7. Establishment of non-invasive diagnostic criteria of prostate cancer using MRI including DWI
  8. Establishment of MRI-guided planning on high-dose-rate brachytherapy (HDR-BT) of prostate cancer
  9. Assessment of secretary flow of bile and pancreatic juice using non-contrast enhanced MR imaging
  10. Non-invasive evaluation of renal function by non-contrast enhanced MR imaging


  1. Support of the surgical procedure in preoperative virtual simulation using multidetector row CT
  2. Establishment of the new systematic imaging diagnostic system using computer-aided diagnosis (CAD) and neural network
b) Basal Research:
  1. Development of new embolic materials for transcatheter arterial embolization (TAE)
  2. Visualization in the hepatocyte of Gd-EOB-DTPA using mapping of a particular element

Clinical Features

1. Imaging Diagnosis (using PACS system)

a) Conventional x-ray (chest, bone, abdomen, etc.): 50 cases/day
b) Computed tomography (4, 4, 16, 64-detector row CT units): 80 cases/day
c) Magnetic resonance imaging (1.5, 1.5, 1.5, 3.0-T units): 60 cases/day
d) Upper gastrointestinal study: 15 cases/day

2. Interventional Radiology
a) Vascular

@ Superselective intra-arterial chemotherapy
A Vascular malformations and hemangiomas
B Continuous intra-arterial chemotherapy using an arterial reservoir
C Transcatheter arterial embolization (TAE) for bleeding, aneurysm, HCC, etc.

b) Non-vascular

D CT-guided interventions

3. Other

a) Participation in various clinical department conferences related to imaging diagnosis

Educational Features

1. System of the Department of Radiology

The Department of Radiology is organized into three individual divisions: Diagnostic Radiology, Nuclear Medicine, and Radiation Oncology. The Division of Diagnostic Radiology includes a professor, an associate professor, three assistant professors, eight assistants, and three graduate students. All staff members have subspecialties of diagnostic radiology and interventional radiology (IVR).

2. Outline of Education

The education system of Kawasaki Medical School adopts integrated curricula, and we are therefore in charge of medical imaging and radiology-related clinical practice. In addition, we teach a part of the lectures on clinical anatomy, neoplasms and the respiratory system in the integrated curricula.

a)‘Medical Imaging' as a course of the integrated curricula

The purpose of our course is to teach the principal of medical modalities, the merits and demerits of medical imagings, medical imaging anatomy, the principles of film reading, and

cardiovascular interventional radiology (IVR).

b) Clinical Practice

Students learn to read typical medical images of various diseases. They also carry out presentations of imagings using a monitor of the PACS system in front of our staff, and are given the chance to participate in a communal discussion. They attend our admitted patient conference and study the skill of film reading.
