AI Technical Summary

Problems solved by technology

[0004] As a result, pre- and post-treatment differences based solely on changes in the magnitude of FDG SUV measurements can lead to false positive results, misdiagnosis of malignancy, etc.
In addition, due to the inherently low spatial resolution of PET detection systems, inhomogeneities within the region of interest may often not be easily resolved

Embodiment Construction

[0017] figure 1 A single imaging system 100 is illustrated comprising a PET gantry section 102 and an MR gantry section 104 , both of which share an examination region 106 . The PET gantry section 102 and the MR gantry section 104 can be used for non-contrast-enhanced studies and contrast-enhanced studies. In another embodiment, PET gantry section 102 and MR gantry section 104 are parts of separate PET imaging system and MR imaging system, respectively. For such embodiments, the PET gantry portion 102 can be part of a PET imaging system or a combined PET / computed tomography (PET / CT) imaging system.

[0018] The PET gantry section 102 includes a gamma-ray radiation sensitive detector array 110 disposed about an examination region 106 . Detector array 110 includes one or more scintillation crystals and corresponding photosensors, such as photomultiplier tubes, photodiodes, or the like. Light is generated when the crystal is struck by gamma rays, and the photosensor receives t...

Abstract

A method includes obtaining a first image of first contrast agent uptake in non tissue of interest of a patient. The first image is generated based on data from first data from a first imaging modality. The method further includes obtaining a second image of second contrast agent uptake in tissue of interest and the non tissue of interest of the patient. The second image is generated based on second data from a second different imaging modality. The method further includes generating a first image mask based on the first image and generating a first feature image based on the second image and the first image mask. The method further includes displaying at least the first feature image.

Description

technical field [0001] The following generally relates to functional imaging and has particular application to positron emission tomography (PET) and magnetic resonance (MR) imaging; however it is applicable to other applications including, but not limited to, computed tomography (CT), ultrasound (US) and / or or other medical or non-medical imaging applications. Background technique [0002] Functional positron emission tomography (PET) has been used to determine information about cellular metabolism as well as cellular trafficking processes. As an example, FDG PET has been used to image a dynamic metabolic tracer (FDG, a glucose analog) uptake in tissues with high glucose metabolism, such as tumor cells, and provide quantitative information about the tissue. One such quantitative measure is the standardized uptake value (SUV), which has been used to monitor tumor development during (chemo / radiation) therapy. Typically, at baseline scans (before treatment), FDG uptake in tu...
