Objective: The authors conducted a study to noninvasively and nonradioactively reveal moyamoya disease (MMD) intracerebral perfusion and perfusion territory supplied by the unilateral internal carotid artery (ICA) and external carotid artery (ECA) and bilateral vertebral arteries (VAs) before surgery and to further identify risk factors for preoperative hemorrhage in adult MMD.

Methods: Forty-three consecutive adult patients with bilateral MMD underwent unenhanced T1-weighted MRI, territorial arterial spin labeling (t-ASL), and unenhanced 3D time-of-flight MRA (3D-TOF-MRA). Clinical factors, including age, sex, hypertension, diabetes mellitus, hyperlipidemia, current smoking status, and history of taking aspirin, were gathered and stratified.

Article Synopsis
  • The study aimed to compare the T2 values of healthy versus diseased Achilles tendons using a new 3D ultrashort echo time (UTE) MRI technique and explored the relationship between T2 values and clinical assessment scores.
  • Ten symptomatic patients and ten healthy volunteers underwent MRI scans, with T2 values calculated for four regions of the Achilles tendons, while clinical outcomes were measured using AOFAS and ATRS scores.
  • Results showed a significant difference in T2 values between groups, with strong negative correlations found between T2 values and clinical scores, suggesting that T2 could serve as a useful marker for detecting and diagnosing Achilles tendon issues.
