01 / MISE EN PLACE

Lay out the
ingredients.

Not a shopping list. A field of observations whose meaning emerges through concordance, contradiction and change.

01Longitudinal imagingMRI / MRA over time

02Lumen morphologySize · shape · lobulation

03Wall informationEnhancement · thrombus

04Flow contextGeometry · haemodynamics

05Clinical modifiersLocation · history · exposure

06Patient contextRisk · preference · uncertainty

02 / THE COMPOSITION

Four movements.
No automatic answer.

Select a movement to unfold the expert reasoning.

OBSERVE

Read the lesion before naming the decision.

Interrogate lumen morphology, wall characteristics, thrombus, parent-vessel geometry and the perianeurysmal environment. Treat every image as a partial view of a dynamic biological system.

OUTPUT / LESION PHENOTYPE

03 / CLINICAL BALANCE

Signals are cumulative.
Certainty is not.

This visual balance is a discussion aid, not a score.

THE SECRET INGREDIENT

Time.

A single image is a moment. Longitudinal observation can reveal whether a lesion remains quiet or changes its character.

HOW TO SERVE

Without unnecessary certainty.

Present what is observed, what is inferred, what remains unresolved and what will happen next. The aim is not merely to select observation or intervention, but to make the reasoning transparent enough for a patient and a multidisciplinary team to understand together.

We interpret a living situation.”Editorial principle / Clinical Recipes
