Problems solved by technology

In normal myocardium, injected contrast agent is excluded from the cell membrane, however, in injured myocardium, the sarcolemma of myocytes becomes permeable to allow accumulation of contrast agent, which results in the observed high enhancement

Embodiment Construction

[0016] Provided herein are clustering and classification methods and apparatus that facilitate imaging systems such as, by way of example, but not limited to, computed tomography (CT) systems. The apparatus and method are illustrated with reference to the drawings, wherein like reference numerals refer to like elements throughout. The purposes of such drawings are illustrative, not restrictive, and are included to illustrate exemplary embodiments of the apparatus and methods of the present invention. Although described in a CT device, it is contemplated that the benefits of the present invention may also be found in all DI medical devices, including Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET), Electron Beam CT ( EBCT), single photon emission CT (SPECT), ultrasound, optical coherence tomography, etc.

[0017] FIG. 1 shows an imaging medical device acquisition system 10 with an associated display 20 . Imaging system 10 may be any medical device, but in...

Abstract

To judge seriousness of a disease based on irrigation and viability of the cardiac muscle. For visualizing constitution elements of tissue or organ to evaluate characteristics of a disease, statistical processing or cluster analysis processing is carried out. By accessing image data including a three-dimensional monophase data set or a three-dimensional polyphase data set of data of interest features of an organ including tissue, that are data obtained together with at least one of an imaging drug, blood, and a contrast agent or a biomedical drug, sorting processing or cluster analysis processing is carried out to obtain processed data sets for visualizing: an imaging drug in tissue, blood, a contrast agent or a biomedical drug; the relative uptake amounts of an imaging drug in tissue, blood, and a contrast agent or a biomedical drug by areas; the relative flows of an imaging drug in tissue, blood, and a contrast agent or a biomedical drug by areas; and purification values or persistence performance of an imaging drug in tissue, blood, a contrast agent or a biomedical drug.

Description

technical field [0001] The present invention relates generally to methods and devices for diagnostic imaging (DI), and in particular to methods and devices providing 3D and 2D relative perfusion activity. Background technique [0002] When a patient enters an emergency room or other clinical setting and is evaluated for a possible heart attack, there are typically three possible outcomes regarding heart muscle health. 1. No disease (and the doctor will not treat the patient), 2. Definite disease (minor disease, and the doctor usually treats it with medication), and 3. Definite disease (serious disease, and the doctor usually uses drugs such as coronary artery bypass grafting treatment with revascularization with surgery (CABG) or angioplasty (AP). [0003] Simple computed tomography (CT) angiography can confirm the absence of disease. However, if disease is present, additional information is needed to determine the severity of the disease. [0004] CT uses anatomical and ...
