There was a time, when X-ray was one of the fundamental diagnostic test advised by physicians. However, nowadays, CT scan is gradually taking it over. We will definitely not see death of X-rays, but recommendation of CT scan is increasing, for the depth of diagnosis and accurate results it provides. As an end user, there are few things that you should be aware of, about CT scanning.
Understand very well from your physician why he is advising you to undergo the scan. Once you are clear with the reasoning, ensure that you are getting your scan done at a reputed diagnostic centre/hospital. This is important because while undergoing a scan, the patient is exposed to certain amount of radiation dose. If the CT scanner is very old, assurance of getting clear images is low. Under such conditions, to get better image results, the rate of radiation dose is often increased, which can be dangerous to the patient.
To a large extent, try and avoid such situations. Today in India, advanced technologies have paved their way in the field of CT scanners, providing early and accurate diagnosis at a very low radiation dose. The world’s fastest CT scanner called Definition Flash1 is available in India, which can scan the patient at the lowest possible dose. For example, it can scan the heart in less than 1 mSv (milli Sievert). Sievert is the unit of radiation exposure. In fact, a human being is exposed to approximately 3 mSv of radiation in nature. You can thus imagine how safe this scanner is.
Children are most vulnerable to radiation. The potential risk from repeated examination adds up over the lifetime, and because children’s tissue is particularly sensitive to radiation, dose levels are an even greater concern. Definition Flash comes with advanced technologies in low dose wherein it can automatically control the radiation dose while scanning children. The scanner also has special features that take care of sensitive organs like eyes and breast, which when exposed to radiation can be traumatic.
The challenge faced today by radiologist is the mounting pressure to reduce dose levels for patients. Nevertheless, the healthcare industry is introducing technological breakthroughs, which have dramatically reduced dose levels not only in CT, but also in angiography, fluoroscopy, mammography and molecular imaging.
As a health conscious citizen, opt for CT scanners (if not Definition Flash) that can control unnecessary radiation dose, but at the same time can provide early and accurate diagnosis.
