on 28 May in King George Medical University, public lecture was taken by Dr Rajendra Prasad regarding prevention of tuberculosis in India. Since implementation of revised national tuberculosis control program around 44 million TB suspects have been examined, 12 million TB patients placed on treatment, 2 million lives are saved in last decade. Dr Prasad reported that in a study conducted, around 192 X-rays (67.6%) out of 284 were having quality problems while 136 X-rays were reported to have wrong diagnosis. So diagnosis of TB can not be made on basis of x-ray, only sputum test is the best way to diagnose TB.
