OBSTETRICAL ULTRASOUND BASIC AND DETAILED ANATOMY PROTOCOL
UOB2- Basic Anatomy to be used for patients that are not
considered high risk.UOBC -Detailed Anatomy to be performed for high-risk
patients. (AMA, BMI >30, DM, known or previous fetal
anomaly and all multiple gestations. See complete list of
indication for Detailed Anatomy exams below.)**Requisitions should be read carefully to ensure the proper exam is performed.
** See separate protocols for OB Follow Up, OB Limited exams and fetal anomalies.
**Detailed Anatomy to be done on all multiple gestation pregnancies.
**If any abnormal fetal findings are discovered on a Basic Anatomy Exam, the exam should be changed to a Detailed Anatomy Exam (UOBC) with corresponding images.
** See specialized Skeletal Dysplasia protocol if long bones measure less than <1%. Measure all long bones bilaterally and perform a Detailed Anatomy exam if long bones measure <2%, the full skeletal dysplasia protocol does not need to be performed.
** See specialized protocol for TTTS (Twin to Twin Transfusion Syndrome) and TAPS (Twin Anemia Polycythemia Sequence) when requested with mono-di and mono-mono pregnancies.
**If anatomy was cleared before 17 weeks 0 days, all anatomy images need to be repeated. If cleared on or after 17 weeks 0 days it does not need to be repeated.
DATING: As a routine, use the date provided by the clinician or patient’s known LMP. Working EDD in EPIC should be used if more than one date is provided. Use AIUM and ACOG dating criteria if dating is unknown.
