Sonography
USG WHOLE ABD+ APPENDIX pairs a full abdominal scan with a targeted look at the appendix, used when appendicitis is suspected. The technique for the appendix, called graded compression, has the sonographer press the probe steadily over your right lower abdomen to push aside bowel gas until the appendix comes into view. An inflamed appendix typically measures more than 6 millimeters across and doesn't compress under that pressure, unlike healthy bowel, which is the core finding this scan looks for. Because appendicitis pain often starts around the belly button before settling into the right lower abdomen, the rest of the abdominal organs are scanned too, both to support the diagnosis and to catch a different cause for the pain.
This scan looks specifically for a swollen, non-compressible appendix over 6 millimeters across, along with signs like fluid or inflamed fat around it, while also checking the rest of your abdominal organs. A visible, non-compressible appendix matching this pattern is the main finding your doctor is looking for.
Appendicitis pain classically starts as a vague ache around the belly button and moves to the right lower abdomen over hours, and USG WHOLE ABD+ APPENDIX is built to investigate that specific pattern alongside a full abdominal review.
To see the appendix clearly, the sonographer presses the probe steadily downward over your right lower abdomen, gradually displacing gas-filled bowel loops that would otherwise block the view. A healthy segment of bowel compresses easily under this pressure; an inflamed appendix does not, since it's swollen and obstructed. This specific technique is what sets this scan apart from a routine whole-abdomen study.
An appendix diameter greater than 6 millimeters, seen without compressing, is the main sign your doctor is watching for. Extra clues include fluid or increased echogenicity in the fat surrounding the appendix, or a small calcified blockage called an appendicolith. This scan is used often in children and pregnant patients specifically because it avoids the radiation a CT scan would involve.
Because appendicitis needs a prompt answer, this scan is typically arranged without delay once your doctor suspects it.
This scan adds a specific technique called graded compression, where the probe presses steadily over your right lower abdomen to bring the appendix into view. A routine whole-abdomen scan doesn't specifically target the appendix this way.
The main sign is an appendix wider than 6 millimeters that doesn't compress under the probe's pressure. Fluid or inflamed fat around it, or a small blockage called an appendicolith, add further support.
Ultrasound avoids radiation entirely, which matters especially for children and pregnant patients, where CT's radiation exposure is a bigger concern.

It's a strong tool, but the appendix can be hard to see in some patients, including people with more body fat. Your doctor may combine this scan with clinical exam findings and sometimes further imaging.
Yes, the rest of your abdominal organs are scanned too, both to support the appendicitis workup and to look for a different cause of your pain.
The probe pressure used for the appendix view can feel uncomfortable, especially if the area is already tender, but the scan itself doesn't use needles or injections.
No. It's ultrasound-based, using sound waves rather than X-rays, so there's no radiation exposure.
There's no single preparation that applies to every patient, and this scan is often arranged without delay once appendicitis is suspected. Ask your doctor or the centre what applies to you.
