Hello,

Radiology involves conducting a series of tests that scan and take pictures of various parts of the body. Radiology helps us diagnose various diseases.

The basic duties of a Radiologist includes communicating with the consulting doctor, carrying out radiography tests recommended by the Radiologist and guiding the patient (before, during and after scan), operating diagnostic equipment, taking care of pre-intra and post scan procedures,analyzing scan results,treating patients using radiotherapy.

No,you can't call a M.Sc Radiologist student to be a doctor .For becoming a doctor in radiology you need to study mbbs and complete your MD in this specific field.
Though,after completing PhD in Radiologist you can be called a Doctorate.
