GSI Spectral CT Scanner
India’s first Discovery CT750-HD FREEdom Edition Dual Energy CT Scanner with GSI Cardiac Spectral Imaging capabilities has just recently been installed in New Delhi. It is the best CT scanner currently available in the world. With the advent of 16, 64, 128 and 256 slice CT scanners, diagnosis of coronary heart disease reached an all time high, since these machines enabled visualisation of the heart and its vessels in great detail non-invasively allowing radiologists and cardiologists to find out the condition of the coronary vessels. But this was not without its problems. Many times it would not be possible to see the condition of the vessels because calcium deposits in them would obscure the view. Also, even if the blockage was visible, it was difficult to tell what kind of deposit the patient has. This Dual Energy Spectral CT scanner actually shifts the CT paradigm beyond slices and enables visualisation of the coronaries with dramatic clarity using much less radiation exposure. Till today, CT scanning could only show the disease, now it is possible to tell the clinician what it is made of so as enable him to plan targeted treatment. CT coronary angiography can now be confidently promoted as a screening tool for people having risk factors for heart disease since the radiation exposure is very low with this system and the information obtained is clear and precise.
