To compare the sensitivities of T2-weighted image (T2WI) and susceptibility-weighted imaging (SWI) in detecting cerebral arteriovenous fistula (AVF), cerebral arteriovenous malformation (AVM), and carotid-cavernous sinus fistula (CCF), and to qualitatively evaluate single-echo SWI (s-SWI) and multi-echo SWI (m-SWI) in characterizing vascular lesions.
From January 2016 to December 2021, cerebral angiography-proven lesions were recruited. The sensitivities of T2WI and SWI in detecting vascular lesions were compared using McNemar's test. Qualitative evaluations of s-SWI and m-SWI were categorized to be of poor, average, or good quality and compared using Fisher's exact test.
A total of 24 patients (mean age: 61 years, 12 female, and 12 male) were enrolled. Twenty patients underwent s-SWI or m-SWI, and four patients underwent both. AVF, AVM, and CCF were diagnosed in 10, 11, and 3 patients, respectively. SWI demonstrated higher sensitivity compared to that of T2WI (82.1% vs. 53.6%, = 0.013). m-SWI showed better image quality compared to that of s-SWI (good quality, 83.3% vs. 25.0%, = 0.009).
SWI demonstrated a higher sensitivity for detecting cerebral arteriovenous shunts compared to that of T2WI. m-SWI exhibited better image quality compared to that of s-SWI in characterizing vascular lesions.
比较T2加权成像（T2WI）和磁敏感加权成像（SWI）在检测脑动静脉瘘（AVF）、脑动静脉畸形（AVM）和颈内动脉海绵窦瘘（CCF）方面的敏感性，并定性评估单回波SWI（s-SWI）和多回波SWI（m-SWI）对血管病变的特征性表现。
纳入2016年1月至2021年12月期间经脑血管造影证实的病变。采用McNemar检验比较T2WI和SWI检测血管病变的敏感性。将s-SWI和m-SWI的定性评估分为质量差、一般或良好，并采用Fisher精确检验进行比较。
共纳入24例患者（平均年龄：61岁，女性12例，男性12例）。20例患者接受了s-SWI或m-SWI检查，4例患者同时接受了两种检查。分别在10例、11例和3例患者中诊断出AVF、AVM和CCF。与T2WI相比，SWI显示出更高的敏感性（82.1%对53.6%，P = 0.013）。与s-SWI相比，m-SWI显示出更好的图像质量（良好质量，83.3%对25.0%，P = 0.009）。
与T2WI相比，SWI在检测脑动静脉分流方面具有更高的敏感性。在对血管病变的特征性表现方面，m-SWI比s-SWI表现出更好的图像质量。
