Medical Imaging


B.S. in Medical Imaging (Radiologic Technology)

The Medical Imaging Program at LIU Post has been a provider of education in diagnostic imaging since 1973 and is one of only a few programs in New York State to offer the entry-level baccalaureate degree in Radiologic Technology. Radiologic technologists operate x-ray and digital imaging machines, digital mammography equipment, computed tomography (CT scan) machines and magnetic resonance imaging (MRI) to provide physicians with images of the skeletal system, organs, tissues and other vessels of the body—important diagnostic tests that help doctors detect and treat illness and injury.

Radiographers utilize ionizing radiation to provide physicians images of the skeletal system, organs, tissues and other vessels of the body; important diagnostic tests that help physicians detect and treat illness and injury. Radiographers are professionals skilled in the use digital x-ray and mammography equipment, computed tomography (CT scan), and magnetic resonance imaging (MRI).

Students in the Medical Imaging program benefit from being part of a small cohort, progressing through their courses as a group, receiving individualized attention from faculty. The B.S. in Radiologic Technology Medical Imaging program provides a strong educational foundation in science and the liberal arts and comprehensive coursework in radiologic technology. Students receive the core knowledge for entry into professional practice as well as tools for lifelong learning. Through the synthesis of clinical and didactic experiences, students develop clinical competence, conceptual understanding and critical thinking skills for effective problem-solving. We seek to prepare graduates who will have essential literacies including written and oral communication skills and be clinically competent professionals able to provide quality care to the community and other groups of interest. 

Accreditation Information: The B.S. in Radiologic Technology is professionally accredited by the Joint Review Committee on Education in Radiologic Technology (JRCERT), located at 20 North Wacker Drive, Suite 2850, Chicago, Ill 60606-3182, Tel. 312-704-5300 and licensed by the New York State Department of Health, Bureau of Radiologic Technology.

Admissions Requirements

If you have ever been convicted of a felony or misdemeanor, or have been subjected to a sanction as a result of a violation of an academic honor code or suspended or dismissed by an educational program designed to meet ARRT certification requirements, you must check with the New York State Department of Health and the American Registry of Radiologic Technologists to verify that you satisfy the requirements for New York State Licensing and the National Registry.

A criminal conviction and/or the use of illegal drugs may impede or bar entry into your chosen field of study. You should be aware that clinical and hospital sites may reject a student, or remove a student from their site if a criminal record is found or if a positive drug test is noted. Inability to gain clinical or field work will result in the inability to meet program objectives and outcomes. Inability to meet objectives and outcomes may result in your failure to complete the program requirements, thus requiring your withdrawal from the program. In addition, the presence of a criminal conviction may also prevent your completion of the required state or federal licensure, certification or registration process.


Application to the Radiologic Technology Program is a two-step process.

The first step is acceptance to LIU Post. You can apply for admission to LIU Post at My LIU or by using the Apply Now button in the upper right-hand corner of this page. For more information on the application process, visit the Admissions Office home page.

Admission requirements include the following:

  • Incoming freshmen must have a solid B average (3.0 or 82-85 grade point average) and an average SAT score of 1000 (Critical Reading and Math combined) or ACT Composite of 20 or above.
  • Transfer students must have completed more than 24 college credits. A minimum college G.P.A. of 2.5 is required for application review. If you have completed fewer than 24 credits, you must also submit high school transcripts and SAT/ACT scores.

The second step requires a formal application to the Bachelor of Science in Radiologic Technology Program. Upon acceptance to LIU Post, interested students may obtain an application packet for the Radiologic Technology Program by calling 516-299-2743. Students should request this secondary application from the program during their sophomore year. Distribution of applications begins in October each year.  

Students enter the professional portion of the program in the fall semester of their junior year. Freshmen and transfer students desiring to enter the program must have completed 64 academic credits of liberal arts and sciences coursework to be eligible for entrance to the Radiologic Technology Program. Students are advised to contact the program office starting in October prior to the fall semester in which they wish to enter.

Admission to the Radiologic Technology Program is highly competitive. Students must have achieved a minimum grade point average (GPA) of 2.0 with a demonstrated interest in science and health and must complete one academic year of Anatomy and Physiology with lab, a basic math (1 semester of algebra or higher), and a basic computer course prior to starting the program.

Application & Prerequisites

The first step is to apply to LIU Post either online, or with a downloadable paper application. You can find both at

Once you have applied to the university, send in any/all official transcripts from previously attended schools to the university. Visit for more information.

There are a few things that are important to know:
