If you want to become a radiology it is best to volunteer in a hospital in your home time that except volunteers. This can help you network with other radiologists in the field. They can also become your future mentors or your employer. .
Pick a college that suits your personality and a major that interests you. You will need to get good grades in college in order to apply for medical school. At the medical school I attended, the average GPA is reported to be 3.85, so even one or two B's can hurt your chances of acceptance.
Aside from this, any major is acceptable as long as you complete the prerequisite courses.
Typical medical school prerequisites include:
Biology: Lecture – 4 semesters; Lab – 1 semester
General Chemistry: Lecture – 2 semesters; Lab – 1 semester
Organic Chemistry: Lecture – 2 semesters; Lab – 1 semester
Biochemistry: Lecture – 1 semester
General Physics: Lecture – 2 semesters; Lab – 1 semester
Math: Statistics – 1 semester
English: Rhetoric (Composition) and Literature – 2 semesters
During college study for and complete the MCAT. Apply to medical schools during your last year of college.
Medical school takes 4 years to complete.
After medical school physicians complete an internship and residency for additional training. These are sometimes followed by an additional year or two of fellowship subspecialty training.
I enjoy my career as a radiologist. I feel like I learn something new every day.
Once residency is completed, you will be able to better negotiate your own hours. As far as whether the field is hard, you should be well-trained to practice after your years of training.
