Automatic image processing pipeline for tracking longitudinal vessel changes in magnetic resonance angiography.

ABSTRACT:

Background

Cerebral vessel diameter changes objectively and automatically derived from longitudinal magnetic resonance angiography (MRA) facilitate quantification of vessel changes and further modeling.

Purpose

To characterize longitudinal changes in intracranial vessel diameter using time-of-flight (TOF) MRA.

Study type

Retrospective longitudinal study.

Subject population

IN all, 112 pediatric patients, aged 9.96 ± 4.59 years, with craniopharyngioma from 2006-2011 scanned annually.

Field strength/sequence

1.5T and 3T TOF MRA.

Statistical tests

Chi-square and Wilcoxon-Mann-Whitney tests.

Assessment

Manual measurements using interventional angiography was established as a reference standard for diameter measurements. Constant and linear quan
