Stress thallium-201 and resting dual intracoronary particulate imaging were evaluated in 120 patients who underwent coronary angiography. Forty of 42 patients without significant coronary disease had normal stress images and 41 had normal rest studies. Eighty-three stress perfusion defects were identified in 61 of 78 patients with coronary artery disease. At rest, 39 of these defects were resolved or improved, whereas 44 remained unchanged. The angiographic presence of collateral vessels and radionuclide evidence of blood flow distribution through them could not always be correlated as 36 angiographic collateral vessels had no regional distribution flow patterns with either method. Particulate studies demonstrated myocardial flow distribution through 25 angiographic collateral vessels and further identified seven collateralized areas not seen angiographically. The resting particulate images additionally defined flow distribution patterns in 15 instances in which the angiogram indicated two potential sources of blood supply.
对120例接受冠状动脉造影的患者进行了负荷铊-201和静息双冠状动脉内微粒成像评估。42例无明显冠状动脉疾病的患者中，40例负荷图像正常，41例静息研究正常。78例冠状动脉疾病患者中的61例发现了83个负荷灌注缺损。静息时，这些缺损中的39个得到缓解或改善，而44个保持不变。侧支血管的血管造影表现与通过它们的血流分布的放射性核素证据并不总是相关的，因为36条血管造影侧支血管在两种方法下均无区域分布血流模式。微粒研究显示了通过25条血管造影侧支血管的心肌血流分布，并进一步识别出7个血管造影未见的侧支区域。静息微粒图像还在15例血管造影显示有两个潜在血液供应源的情况下定义了血流分布模式。
