The nearest metro station is Welcome from where you can take the RTV or Auto. If you are coming from ISBT then you can take bus number 211 for the Bihari Colony from where you can take the RTV.
Last week I visited to the Shri Anandpur Trust located in the Krishna Nagar for Chest CT Scan of my wife. The price of the Chest CT Scan is Rs1020. The infrastructure facilities at the Shri Anandpur Trust are very good.
First of all you will take a token from the entrance gate and when your turn will come, you will visit to the cash counter for submit the fees. The counter clerk will give receipt of the bill that you have to take at the reception where the receptionist will tell you about where to go for the CT scan. He will also give a form and photo copy of your doctor’s prescriptions.
