Diagnostic Medical Sonography

BS in Diagnostic Medical Sonography

Sonography (DMS) uses high frequency sound waves (ultrasound) to produce a dynamic visual image of internal organs, tissues, or blood flow inside the body. It is a mode of non-invasive imaging that is widely used in medical practice.

Students enter the professional phase of their education at the beginning of their third full time academic year. During the professional phase, the curriculum sequences didactic education, scanning laboratory experience in DMS with extensive clinical (hands-on) experience.

Prior to completion of the program, students will be eligible to take the American Registry of Diagnostic Medical Sonography (ARDMS) examination in three different concentrations (abdominal, obstetrics and gynecology and echocardiology [adult heart]) and will have access to clinic-based careers in diagnostic medical sonography in multiple specialties.

DMS students are eligible to sit for the national credentialing examinations in Adult Echocardiography, Abdominal Sonography and OB/GYN Sonography along with the Sonography Principles and Instrumentation (SPI) examination prior to completing their degree, and therefore, can be credentialed by the time of graduation. This makes LIU DMS students particularly attractive to potential employers.

The Diagnostic Medical Sonography program is accredited by the Commission on Accreditation of Allied Health Education Programs (www.caahep.org) upon the recommendation of Joint Review Committee on Education in Diagnostic Medical Sonography. The program has been placed on Probationary Accreditation as of May 19, 2023.

The DMS program at Long Island University is no longer accepting new students.
Current students will continue in the program until they have completed their course of study.

Admissions and Application

Application to the DMS Program is a two-step process. 

1) The first step is acceptance to LIU Brooklyn. You can apply for admission to LIU Brooklyn 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. LIU Brooklyn 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 2.75 is required for application review. If you have completed fewer than 24 credits, you must also submit high school transcripts and SAT/ACT scores.

2) The Bachelor of Science in Diagnostic Medical Sonography is a competitive program.
An additional application is required for students who believe they are ready to start years 3 and 4 of the DMS program. Meeting the minimum DMS program requirements in years 1 and 2, does NOT guarantee acceptance into years 3 and 4.  Space in the program is limited, and not all eligible applicants will be accepted.

All applicants for Year 3 (current LIU students, returning LIU students & transfer students) must complete a DMS program application and be accepted into the DMS program in order to continue on to the DMS sequence of courses in years 3 and 4. You must request this application from the DMS Program directly by sending an e-mail to bkln-dms@liu.edu.

In addition to timely completion of the DMS program application, students must:

  • If transferring in, students must complete an application to LIU through the admissions department and be accepted to the university
  • A minimum of 60 undergraduate Liberal Arts and Science credits, including the following:
    • Oral Communications (3 credits)
    • Anatomy and Physiology I and II with lab (8 credits)
    • Physics with lab (4 credits)
    • Statistics (3 credits)
    • Algebra (3 credits)
  • Have a minimum overall GPA of 2.75 and a science & math GPA of 2.75
  • A minimum of ‘C’ in the science and math courses
  • Meet minimum writing requirements.

Program Information

  • The Professional Studies portion of the program consists of 5 semesters, including a 12-week summer session.
  • It is a full-time, program.  Classes can start as early as 7:30 AM and can end as late as 9:00 PM.  Clinical hours are typically 8:00 AM – 4:00 PM or 9:00 AM – 5:00 PM. Clinical hours may vary to include evenings and weekends
  • It is a multi-modality program.  It consists of 3 specialties; Abdominal Sonography - Extended, OB/GYN Sonography and Adult Echocardiography. Also included are Non-Invasive Vascular classes.
  • Students are eligible to take their national boards given by the American Registry of Diagnostic Medical Sonographers (ARDMS) prior to graduation in Sonography Principles and Instrumentation (SPI), Abdominal Sonography - Extended, Obstetrics & Gynecology Sonography, and Adult Echocardiography.
  • The clinical and didactic portions are designed to be taken simultaneously.  Students cannot continue to the next semester without successfully completing all sonography courses in the previous semester.
  • If a student receives a C- or below in two professional study courses, they will not be able to continue in the DMS program.
  • It is recommended that students do not work while in the professional phase of the program.
  • Students are placed in multiple clinical sites. Most of the clinical sites are hospitals. Students are responsible for transportation to clinical sites, which may be up to 2 ½ hour commute.
