DIAGNOSTIC MEDICAL SONOGRAPHY PROGRAM
DMS 226 Obstetrical Sonography II
2 lec., 3 lab., 3 Credits (5 hours)
Prerequisites: BIO-109; DMS-102; DMS-113; DMS-115
Co-requisites: DMS-201; DMS-204; DMS-213; DMS-218
COURSE DESCRIPTION: OB Sonography II is a continuance of Ob/Gyn Sonography designed to familiarize
the students with the pathophysiology of the female reproductive system. Pelvic scanning protocol along with
sonographic interpretation will be utilized in labs. Normal and abnormal obstetrical patterns will be taught and
emphasis will be placed on recognition of normal anatomical appearances of a fetus in the second and third
trimester. Chromosomal and congenital anomalies are discussed as well as the importance of differential
diagnoses. High risk OB ultrasound is presented. Pathological and physiological data for interpretation is stressed.
The sonographic criteria for evaluation of the gravid uterus, postpartum uterus, and the fetus will be included.
COURSE OBJECTIVES:
Describe scan protocol in ultrasound scanning as it pertains to obstetrical imaging in the 2nd and 3rd
trimester.
Describe normal and abnormal developments occurring in the 2nd and 3rd trimester of pregnancy.
Evaluate fetal age and fetal well being using sonographic measurements and criteria.
Identify congenital and chromosomal abnormalities diagnosed by ultrasound.
Explain Chorionic Villus Sampling, amniocentesis, and PUBS when dealing with high risk pregnancy.
Explain the components of a Biophysical Profile exam.
Identify normal and abnormal sonographic appearances when dealing with the postpartum uterus.
Describe the sonographic appearance of the normal and abnormal placenta and umbilical cord.
Describe amniotic fluid production in the 2nd and 3rd trimester and
Analyze the amniotic fluid volume
Discuss new techniques utilized in-utero to correct congenital defects in the later stages of pregnancy.
TEXTBOOKS REQUIRED:
Hagan-Ansert, Sandra; Textbook of Diagnostic Ultrasonography; 77h edition; Mosby, St. Louis, Missouri,
2012.
COURSE POLICIES:
Laboratory scanning time CANNOT be made up.
Missed quizzes or exams, due to tardiness or absence must be made up in the Testing Center before the
next class meeting.
A physician’s note must be submitted for any absence on a scheduled test day. The missed test must be made up in
the Testing Center before the next class meeting.
Cell phone use is prohibited in the classroom and must be turned off at all times.
For lab scanning, students are required to be prepared for a pelvic ultrasound exam (properly distended
bladder). Failure to be prepared will cause your classmates to lose precious scanning time.
The lowest quiz grade will be dropped.
ASSESSMENT: Knowledge of course objectives will be assessed by verbal questions prior to, and at the end of
each class, quizzes, tests, and lab worksheets. Students will be required to perform a full female trans-abdominal
pelvic exam, a full trans-vaginal pelvic exam on an ultrasound phantom, and a fetal biometry exam (BPD, HC,
AC, and Femur length) on an ultrasound phantom.
