Thallium imaging with single photon emission computed tomography

The relation of amino-terminal propeptide of type III procollagen and severity of coronary artery disease in patients without myocardial infarction or hibernation

“…We used the 16-color scale in image interpretation. The left ventricle was divided into 10 segments, as proposed by Iskandian et al [17] Thallium-201 activity in each segment was graded as 3 (normal), 2 (mild reduced), 1 (moderately reduced) or 0 (severely reduced or absent). A segment was considered abnormal if its grade was 2 or less [18].…”

Clinical correlation between increased lung to heart ratio of tecnetium-99m sestamibi and multivessel coronary artery disease

“…Increased LHR in patients undergoing exercise as well as adenosine pharmacological Tl-201 myocardial perfusion imaging correlates with multi-vessel or severe CAD [3,8 -10]. In addition, increased lung uptake of Tl-201 is a predictor of adverse cardiac events and identifies a group of patients with poor prognosis [11,12]. Ventricular decompensation leading to increased left ventricular end diastolic pressure is thought to be the underlying mechanism behind the increased lung uptake in patients undergoing exercise myocardial perfusion imaging [6,8].…”

Simultaneous Dobutamine Stress Echocardiography and Thallium-201 Perf usion Imaging for the Detection of Coronary Artery Disease

“…A myocardial segment was considered ischemic in the presence of a totally or partially reversible defect. For correlating coronary artery anatomy, the images of three orthogonal planes were divided into 10 segments, as proposed by Iskandrian et al [16], The septum and the anterior segments were considered to correspond to the left anterior descending territory, the inferior segment to the right coronary artery territory, and the lateral segment to the circumflex territory. The apex did not define any par ticular vascular distribution.…”
