There are moments when a doctor knows their diagnosis has made a profound difference in a patient’s treatment. Often, the patient may never fully understand the complexities and challenges that went into reaching that conclusion. As Radiologists, we take pride in the behind-the-scenes work — the meticulous analysis and dedication that helps doctors make life-changing decisions.

This log book reflects a few of those moments, reminding us of the meaningful impact we make on patient care.

Aberrant right subclavian artery (ARSA)

 



Looking Beyond the Primary Finding: The Value of a Detailed Fetal Ultrasound

A Fetal Well-Being Ultrasound was performed for the evaluation of fetal cerebral ventriculomegaly.

In addition to confirming ventriculomegaly, the examination also identified an aberrant right subclavian artery (ARSA)—an important soft marker associated with an increased likelihood of Trisomy 21. When present, ARSA can significantly increase the estimated risk and may warrant further fetal assessment and genetic counseling in the appropriate clinical context.

This case highlights the importance of a meticulous, systematic fetal ultrasound examination, where identifying associated findings can have a meaningful impact on prenatal risk assessment and clinical decision-making.
