Radiation in small amounts is safe for Radiologists to use on patients when taking images of the human body. Most radiation experts believe there is a wide safety margin when only one or two studies are done with x-rays or nuclear medicine drugs. Cause for concern increases when repeated studies are done within a short period of time.
We practise ALARA ( ie ) give radiation in As Low As Reasonably Achievable
We have an effective Radiation Safety program and Quality Assurance program to give you the best possible diagnostic information with the least Radiation dose.
Our Physicians carefully administer radiation dosage according to the patient size and age. We use the least amount on patients and at the same time ensure Physicians receive a clear image and can easily identify any abnormalities.
Radiation doses delivered are monitored for each patient and audited.
Repeat x-ray rates are monitored and have been consistently below 1% of our total x-rays.
Special lead shields are used to reduce radiation to vital organs like thyroid, gonads etc during X-rays and CT scans.
Children : An alternative imaging like ultrasound or MRI is done when feasible. However if CT is to be done then we have special protocols to maximally reduce the radiation doses.
Pregnancy : We generally avoid CT scan during pregnancy especially during the first 15 weeks. However in emergencies like head injury or suspected pulmonary embolism ( clots in pulmonary artery) CT scan will be done without significant radiation dose to the fetus.
We generally enquire about the possibility of you being pregnant before doing the test. This is done for the safety of the mother and the child.
Some tests require injection of contrast (dyes) into your veins to provide more information. These dyes are generally safe. However in extremely rare cases an allergic reaction can occur. At the Department, proactive steps are taken to anticipate problems and identify high risk patients to initiate appropriate action.
Ensure the renal function is normal by doing blood tests especially in patients over 40 years of age and in Diabetics. A pre-existing altered renal function may increase the risk of renal failure.
Check for hydration of patient and correct it if necessary.
Diabetic patients who take Tablet Metformin are advised to stop it for 48 hours.
Patients who have a history of allergy to these dyes or other multiple drugs are given a prophylactic combination of drugs prior to the CT scan / MRI to reduce the risk.
Some diseases like Multiple Myeloma, Pheochrmocytoma, Thyrotoxicosis may require special care.
BE ASSURED WE ARE THERE TO HANDLE ANY EMERGENCY, THOUGH IT IS EXTREMELY UNLIKELY TO HAPPEN.
The MRI is a permanent magnet which may interfere with some of the devices implanted in your body. MRI may not be feasible in some patients.You will be given a detailed questionnaire to identify your fitness for the MRI. The Doctors will discuss any special concerns you have.
To maintain low radiation levels during radiological procedures, the Department of Radiology at GKNM Hospital benchmarks high standards for its personnel and equipment. The Doctors, Nursing staff and Technicians are highly trained and qualified . Staff undergo periodic re-education and training.
All equipment are monitored on a regular basis to ensure compliance with standards as prescribed by Organisations like Atomic Energy Regulatory Board (AERB), National Accreditation Board for Hospitals (NABH) among others. Preventive maintenance is carried out regularly. All regulatory statutory requirements of the country are met.
GKNM Hospital is one of the few selected hospitals in India to acquire the full field Digital Mammogram. This state of art machine gives you the advantage of better image quality at considerably lower radiation dose and examination time.
We are the first and only centre in Coimbatore to have the 3D Tomosynthesis. This revolutionary technology is designed for early detection of suspicious lesion in dense breast which normally would be difficult to visualize. Stereotactic biopsy is also done to biopsy suspicious lesions and calcification.
GKNM Hospital has brought the latest in Digital X-ray to Coimbatore. The high resolution X-rays are processed almost instantaneously, considerably reducing the examination time. Also the radiation dose to patient is reduced by almost 30%
