MRI Department, Institute of Child Health, Calcuta

  • How long it is open?
    It is open from 9 a.m. to 7pm on weekdays. On Sunday, it is open from 9am to 1pm.
  • What is the usual time required for MRI scan?
    About 30 minutes.
  • How an appointment is made?
    It is usually done at the reception of MRI department by personal visit or by telephone. Telephone No.s (033)2289-3526 and (033)6526-6969.
  • What preparation is needed for MRI?
    Usually no preparation is needed. For MRCP study 4-6 hours fasting is needed. For children, oral sedation is usually required. In some hyperactive, restless patients anesthesia is needed. We have fully equipped setup for anesthesia and extremely competent anesthetist for such patients. About 6 hours of fasting is needed prior to anesthesia.
  • Academically important cases are published in the monthly journal of the department "Inner Vision" and distributed to the doctors.

MRI Unit

MRI Unit
The MRI Unit at ICH

The MRI unit in the Institute of Child Health is operational since January, 2006. It was inaugurated by Hon’ble Mayor of Kolkata Municipal Corporation on 18th of January, 2006 in presence of respected Swami Sarvalokananda Maharaj and Mrs. Krishna Bose.

This unit is equipped with a modern MRI scanner of Siemens Ltd., Open Gantry type. Because of the open system, small children and claustrophobic individuals can undergo scanning procedure much comfortably than the more conventional tunnel type model.

The ambience of the unit is very comfortable. The temperature is maintained in a comfortable range. The unit is fully computerized.

MRI Unit

The unit performs scanning of both adult patients and children with equal care and efficiency. The price for the different scanning procedures are kept in an extremely affordable range in a view to cater the underprivileged section of the community. Hospital patients are offered discounted rates so that they are not deprived from the benefit of this modern imaging technology.

Frequently Asked Questions (FAQ)

What is MRI?
MRI stands for Magnetic Resonance Imaging. When a patient is placed in the magnetic field inside the scanner and radio-frequency (RF) is applied, certain nuclei of the patients body absorb energy and releases subsequently (when the RF is terminated) to give MR signal.

Is there any Radiation hazard ?
No. Unlike X-ray or CT scan there is no ionizing radiation involving in MRI. So repeated examinations, pediatric scanning or even obstetric examination(in later part of gestation) can be performed safely.

Is any contrast needed?
Sometimes contrast is needed , less often than required in CT scan. MR contrast is made of Gadolinium compound and introduced intravenously. It is much less toxic than iodinated contrast and allergic reactions are infrequently met with.

How angiography is done with MRI?
Angiography is done usually without any contrast. The inherent high contrast provided by the flowing and stationary protons in blood and blood-vessels provide the contrast. However, at times contrast is administered for better visualization.

What are the applications of MRI?
Any part of human body can be imaged with MRI. However, certain parts are specially recommended for MR imaging and give unparallel imaging quality because of high intrinsic soft- tissue contrast and excellent spatial resolution. For example, Brain, spine, joints, biliary tree, urinary tract, orbital structures, structures of paranasal sinuses and ear.

Brain : High degree of contrast is provided between gray and white matter. Any lesion in brain parenchyma is detected with alteration in signal intensity in that region. Myelination pattern can be studied in growing children.

Spine : Excellent for degenerative spinal disease, disc prolapse, evaluation of trauma, cord injury etc. Sensitivity is also very high for spinal neoplasms and vascular malformations.

Joints : Undoubtedly the best imaging option for soft tissues around a joint- cartilage, tendons, muscles and ligaments. Marrow abnormalities are also detected very early, cortical bone gives hypointense signal on MR. It is extremely sensitive for detection of even small amount of effusion.

Abdomen: Commonly indicated conditions are MRCP, liver masses, urinary tract imaging , prostatic malignancy, gynecological malignancies like carcinoma cervix, ovarian tumor etc. Benign gynecological conditions like fibroid, adenomyosis, endometrioma etc. can also be imaged by pelvic MRI examination. MRCP (Magnetic Resonance Cholangio-pancreatography) is an excellent tool for visualization of biliary tree without any intervention or contrast administration. MR-urography and MR- fistulogram are indicated for urinary tract and perianal fistula imaging respectively.
