  • The department of Radio-diagnosis was established at inception of Central Referral Hospital in 1999. Over the years the department has grown exponentially and currently has various state of the art equipments i.e. 64 Slice Brilliance Cardiac CT (Philips), high end 4D Color Doppler with shear wave Elastography, MRI 1.5T, 1000mA Digital Radiography, Computed Radiography and Mammography.
  • The department is fully digital with a plan to install PACS (Pictorial Archiving & Communicating System) in near future. This will help in becoming filmless for in patients.



  • Provides radiological services to all admitted patients as well as out patients attending various OPDs and Emergency Department of CRH.
  • The radiological facilities are provided round the clock. During off duty hours the procedures are carried out by the faculties on call.
  • Academic activities like formal lectures and practical teaching classes in the department for MBBS students are undertaken as per the laid down schedule.
  • Discussion with post graduate students (DNB) is a regular practice. It mainly involves unusual / interesting cases undergoing various radiological procedures in the department.
