US301 Sonographic Exploration

Discussion 13

What is the primary purpose of sonographic protocols in clinical practice?

To ensure consistent, complete, and standardized imaging so every patient receives the same high-quality diagnostic evaluation.

What does ALARA stand for, and why is it important in ultrasound?

"As Low As Reasonably Achievable"—it ensures sonographers use the lowest exposure necessary to obtain diagnostic images, promoting patient safety.

What is the difference between SAG and TRV imaging planes?

SAG (longitudinal) images show structures from superior to inferior, while TRV (transverse) images show structures from right to left.

What should every pelvic ultrasound protocol include?

Survey of the uterus, endometrium, ovaries, adnexa, cul-de-sac, and measurement of all relevant structures.

What is the purpose of Doppler in sonographic exams?

To assess blood flow, detect vascularity, evaluate resistance, and identify abnormalities like torsion or abnormal perfusion.

What is the required patient prep for a transabdominal pelvic ultrasound?

A full bladder to act as an acoustic window and improve visualization of pelvic structures.

What measurement is always required in an early OB ultrasound?

The crown-rump length (CRL) to establish accurate gestational age.

Why is proper annotation important in sonographic imaging?

It identifies the organ, side (RT or LT), plane, and any pathology—ensuring images are clear and ready for interpretation.

What is the role of a sonographer during a focused (limited) exam?

To evaluate a specific area or symptom such as pain, bleeding, or suspected pathology, following tailored protocols.

What should sonographers do if they discover an urgent or unexpected finding?

Notify the interpreting physician or radiologist immediately and document the finding according to department protocol.
