The doctors in the west may be too much worried about the insurances and its consequences. But why the Indian doctors resort to the ct scan without a second thought, people dont understand. Its for the money only.Every body is aware of the nexus between these doctors, pharmaceutical reps, labs and scan centres. A lay man does not know the difference between mri and ct scan. MRI is defenitely costlier and given a choice the ordinary people will only go for the ct scan. NObody from the hospital side will bring to notice the hazards.
