Fetal Abdomen and Pelvis coronal plane

---

A coronal oblique plane of the mid-abdomen and pelvis is obtained to demonstrate the right and left kidneys. This is achieved by turning the transducer 90 degrees from the axial plane at the level of the mid-abdomen and sliding obliquely to display both kidneys in the same view. Color Doppler may be added to demonstrate both renal arteries, thus confirming the presence of both kidneys. This step is not necessary however, especially when the kidneys are easily demonstrated on Gray scale ultrasound. Abnormalities that can be detected by the axial and coronal planes of the fetal abdomen and pelvis include abdominal wall defects, abnormal situs, urogenital anomalies with or without megacystis, intraabdominal cystic structures, bowel dilation, single umbilical artery, and others.

Coronal Plane — Fetal Abdomen & Pelvis

Coronal View — Abdomen & Pelvis

[Ultrasound image placeholder: Fetal abdomen & pelvis coronal view]

Caption: Frontal (coronal) section showing abdominal organs and pelvic structures

1. Which organs are commonly seen in a coronal fetal abdominal scan? 1. कोरोनल भ्रूणीय उदर स्कैन में आमतौर पर कौन से अंग देखे जाते हैं?
A. Liver, stomach, kidneys and urinary bladder
B. Only brain structures
C. Placenta and umbilical cord only
D. Fetal limbs only

Explanation: Coronal sections display frontal views of abdominal viscera and the bladder in the pelvis.

2. The coronal plane divides the body into which parts? 2. कोरोनल प्लेन शरीर को किन भागों में विभाजित करता है?
A. Anterior (front) and posterior (back)
B. Left and right halves
C. Superior and inferior
D. Oblique sections only

Explanation: Coronal plane is vertical, separating front from back anatomical compartments.

3. Which pelvic finding is best assessed on coronal pelvic views? 3. कोरोनल पेल्विक व्यू पर कौन सा पेल्विक निष्कर्ष सबसे अच्छा आंका जाता है?
A. Bladder outlet obstruction and pelvic kidney anomalies
B. Fetal lung maturation
C. Only umbilical cord knots
D. Placental calcification

Explanation: Coronal pelvic images show bladder, ureters and pelvic organs helpful for obstruction or ectopia detection.

4. How does coronal imaging help detect malrotation or situs anomalies? 4. कोरोनल इमेजिंग कैसे मालरोटेशन या साइटस असामान्यताओं का पता लगाने में मदद करती है?
A. By showing organ positions relative to midline and each other (eg liver, stomach, spleen)
B. Only by Doppler flow
C. By measuring femur length
D. It does not help

Explanation: Coronal views demonstrate left-right organ relationships and can reveal heterotaxy or malposition.

5. Which sign on coronal view suggests urinary tract dilation? 5. कोरोनल व्यू पर किस संकेत से मूत्र मार्ग का फैलाव संकेतित होता है?
A. Enlarged renal pelvis and dilated ureters projecting into pelvis
B. Small stomach only
C. Increased femur echogenicity
D. Placental lakes

Explanation: Coronal imaging can show continuity of dilated collecting systems into the pelvis and bladder.

6. What is a limitation of coronal fetal abdomen imaging? 6. भ्रूणीय उदर की कोरोनल इमेजिंग की क्या सीमा है?
A. Limited by fetal position and acoustic window — may need complementary planes
B. Always provides complete information
C. Only limited by maternal blood pressure
D. Only used for Doppler

Explanation: Like other planes, coronal views can be limited by fetal lie, maternal habitus and bowel gas.

7. Which complementary view is essential with coronal imaging? 7. कोरोनल इमेजिंग के साथ कौन सा पूरक व्यू अनिवार्य है?
A. Axial (transverse) and sagittal views for full anatomical correlation
B. Only maternal leg view
C. Only head circumference
D. No complementary view needed

Explanation: Orthogonal planes confirm location, extent and relationships of findings seen on coronal sections.

8. How should coronal images be labeled in the report? 8. रिपोर्ट में कोरोनल छवियों को कैसे लेबल किया जाना चाहिए?
A. Indicate orientation (coronal), side (L/R if applicable), anatomical level and any measurements
B. Only date
C. Only technician initials
D. No labeling

Explanation: Proper labeling ensures reproducibility and clarity for follow-up or multidisciplinary review.

9. Which finding on coronal view may be a false positive and needs confirmation? 9. कोरोनल व्यू पर कौन सा निष्कर्ष झूठा सकारात्मक हो सकता है और पुष्टि की आवश्यकता है?
A. Apparent renal pelvic dilation due to transient fetal bladder filling or angle of insonation
B. True diaphragmatic hernia only
C. Always indicates chromosomal anomaly
D. Only indicates oligohydramnios

Explanation: Dynamic factors and viewing angle can mimic dilatation; confirm with multiple planes and repeat imaging.

10. What should the report include when coronal imaging shows an abnormality? 10. जब कोरोनल इमेजिंग में असामान्यता दिखाई दे तो रिपोर्ट में क्या शामिल होना चाहिए?
A. Description of abnormality, measurements, orientation, suggested follow-up or additional imaging (eg axial/sagittal, MRI)
B. Only technician name
C. Only fetal gender
D. No details—just "abnormal"

Explanation: Detailed documentation guides management, helps specialists and assists future comparisons.
