简介
Background
Intraluminal thrombus (ILT) signal intensity on MRI has been studied as a potential marker of abdominal aortic aneurysm (AAA) progression.
Purpose
1) To characterize the relationship between ILT signal intensity and AAA diameter; 2) to evaluate ILT change over time; and 3) to assess the relationship between ILT features and AAA growth.
Study Type
Prospective.
Subjects
Eighty AAA patients were imaged, and a subset (n = 41) were followed with repeated MRI for 16 ± 9 months.
Field Strength/Sequence
3D black‐blood fast‐spin‐echo sequence at 3 T.
Assessment
ILT was designated as "bright" if the signal was greater than 1.2 times that of adjacent psoas muscle. AAAs were divided into three groups based on ILT: Type 1: bright ILT; Type 2: isointense ILT; Type 3: no ILT. During follow‐up, an active ILT change was defined as new ILT formation or an increase in ILT signal intensity to …
