How to Read and Understand a Pregnancy Ultrasound Report

Pregnancy ultrasound reports often contain medical terminology and abbreviations. Understanding these reports provides valuable insights into pregnancy progress and fetal well-being. This guide helps expectant parents navigate this important medical document with greater confidence.

Decoding the Report’s Structure

An ultrasound report is a formal medical document generated after a sonography examination. It is created by a sonographer and interpreted by a radiologist or sonologist, who specializes in medical imaging. The report communicates detailed observations to the referring healthcare provider.

Most reports follow a standardized structure. Initial sections include patient identification and the clinical reason for the ultrasound. The core has two parts: “Findings” and “Impression” or “Conclusion.” “Findings” presents objective observations and technical details. The “Impression” synthesizes these findings into a concise summary, offering the radiologist’s expert interpretation.

Understanding Key Measurements

Pregnancy ultrasound reports feature various measurements providing information about fetal growth and gestational age. Crown-Rump Length (CRL), the length from head to torso, accurately estimates gestational age between 6 and 13 weeks.

As pregnancy progresses, other measurements assess growth. Biparietal Diameter (BPD) measures fetal head diameter, and Head Circumference (HC) measures around the head. These are used for age estimation and head growth monitoring. Abdominal Circumference (AC) indicates fetal growth and estimated weight.

Femur Length (FL), the thigh bone measurement, along with BPD and AC, contributes to Estimated Fetal Weight (EFW). Percentile rankings indicate how a baby’s measurements compare to norms, helping determine if growth is as expected.

Assessing Fetal Anatomy and Well-being

Fetal Heart Rate (FHR) is a key indicator, typically 110-160 bpm through most of pregnancy. Early in pregnancy (8-10 weeks), FHR can be higher (150-170 bpm) before decreasing. Monitoring FHR confirms viability and provides insights into cardiac function.

Amniotic Fluid Index (AFI) assesses fluid volume. AFI is calculated by measuring the deepest fluid pockets in four uterine quadrants. Normal AFI typically ranges from 8 to 18 cm. Deviations, such as oligohydramnios (low fluid, below 5-6 cm) or polyhydramnios (excess fluid, above 24-25 cm), may require further evaluation.

The placenta’s location (anterior, posterior, fundal, or lateral) and appearance are noted. Its position is usually determined during the 18-21 week anatomy scan. The sonographer assesses major organ systems, including the brain, spine, heart (checking for all four chambers), kidneys, bladder, stomach, and limbs, to confirm their presence and normal development and detect certain congenital conditions.

Interpreting Findings and Next Steps

The “Impression” or “Conclusion” section provides the radiologist’s concise summary and interpretation of all findings. This section highlights significant observations and offers potential diagnoses or recommendations for further evaluation. It serves as the radiologist’s expert opinion, guiding the referring physician in patient management decisions.

While understanding your ultrasound report can be empowering, it is a medical document requiring professional interpretation. A comprehensive explanation and personalized advice should always come from your healthcare provider. Your doctor or midwife will discuss results in the context of your overall health and pregnancy, addressing concerns and outlining appropriate next steps.
