A Practical Introduction to CT 

A noble act. Making everyone understand the very essentials of the imaging compartment so that they can use it for the benefits of others. Much appreciated.

Dude! I am 37 years old going into radiology after spending my 20s and 30s in a non medical related field. Your videos are so easy to digest and have given me a vigor that has been crucial in overcoming my apprehension to starting something this complex this late. Thank you!

I'm in med school and no prof has explained this well. But u did such a good job. thanks!

This is outstanding teaching. I can’t imagine the hard work which was put in to make it so easy for us.

Currently cross training in CT and this is the most helpful explanation of the basics of CT imaging that I've seen so far. So helpful!

Being a resident surgeon in training, I knew these concepts from undergraduate level but application of these concepts were made crystal clear by you. Thank you Rajesh sir!

Your videos were great when I first listened to them as a second year med student, and helped me not look like a complete fool when asked to explain Hounsfield units during my elective radiology rotation early in third year! Thanks bro

The best radiology teaching I have come across.

I can't thank you enough for this video. Your explanation is simply amazing and it is FREE!!

My clin med prof recommended your videos and i'm so glad she did! You have helped me immensely. Brilliant!
