WALL / SIGNAL
THE CLINICAL QUESTION

What does the wall add—and what can it not establish alone?

MISE EN PLACE

Six ingredients,
one interpretation.

01Acquisition protocol
02Pre- and post-contrast series
03Pattern and distribution
04Lumen–wall relationship
05Thrombus context
06Interval comparison
THE METHOD

Four movements.

01

Standardise

Begin with comparable acquisition and careful attention to artefact.

02

Localise

Describe enhancement by location, pattern and relationship to adjacent structures.

03

Correlate

Read wall information alongside morphology, flow and longitudinal change.

04

Qualify

Separate an imaging observation from a biological conclusion.

THE SECRET INGREDIENT

Comparability.

Wall signal becomes more useful when acquisition, timing and interpretation are sufficiently consistent to support a genuine longitudinal conversation.

WALL / LUMEN / TECHNIQUE
INTERPRETIVE TENSIONS

Hold both sides
in view.

Expert synthesis is rarely a choice between simple opposites. The work is to understand how each tension changes confidence.

HOW TO SERVE

Make the reasoning visible.

Report the pattern, distribution and technical confidence before offering a biological interpretation. Place enhancement beside morphology, thrombus, flow and change over time.

The wall is not a verdict. It is another witness.Clinical Recipes / Editorial reflection
KEEP IN VIEW

Enhancement is an observation requiring technical and clinical context; it is not a stand-alone treatment indication.
