OBJECTIVES To investigate dual-phase multi-detector computed tomography (MDCT) for assessing extent and severity of jeopardised and infarcted myocardium subtended by infarct-related artery (IRA), and its indication for revascularisation after acute myocardial infarction (AMI). Designs, setting and PATIENTS Prospective, single-centre study included 107 patients with uncomplicated post-AMI 3-7 ...

introduction spect projections are contaminated by scatter radiation, resulting in reduced image contrast and quantitative errors. backscatter constitutes a major part of the scatter contamination in lower energy windows. the current study is an evaluation of the effect of backscatter material on fwhm and image quality investigated by monte carlo simulation. materials and methods simind program...

UNLABELLED Intraoperative visualization techniques promise to significantly improve the detection and resection of tumors. In this study, we used an anti-carcinoembryonic antigen (CEA) antibody (MN-14) tagged with both a radiolabel ((111)In) and a fluorophore (IRDye 800CW) for radionuclide detection and intraoperative fluorescence imaging, respectively. METHODS For this purpose, we prepared a...

OBJECTIVE A dual-isotope imaging protocol using 99mTc-labeled red blood cells with 111In capromab pendetide monoclonal antibody imaging for detective and localizing nodal metastasis in prostate cancer is described. METHODS This protocol involves a single SPECT acquisition that is less time consuming and more comfortable for the patient than the currently recommended method, which requires two...

We present the case of a 62-year-old woman with chest pain and a history of an inferior myocardial infarction for which she underwent stenting in the right coronary artery. Patient was evaluated by cardiac SPECT and the recently introduced dual-source computed tomography (DSCT) system (equipped with two X-ray tubes and two corresponding detectors), in order to detect ischemia associated to sten...

PURPOSE This work is a preliminary study of a stationary cardiac SPECT system. The goal of this research is to propose a stationary cardiac SPECT system using segmented slant-hole collimators and to perform computer simulations to test the feasibility. Compared to the rotational SPECT, a stationary system has a benefit of acquiring temporally consistent projections. The most challenging issue i...
