Problems solved by technology

Medical imaging with contrast agents here has the fundamental problem of achieving a contrast enhancement in vessels or tissues that is constant over time or simultaneously with the data acquisition, while specifically aiming to achieve contrast enhancement using the smallest possible amount of contrast agent
This results in inefficient use of contrast media and increases patient risk and examination costs

Embodiment Construction

[0038] figure 1 An example of the sequence of the diagnostic imaging process using contrast dosing is shown. The bottom area shows the timing diagram of the CT scan (CT). First, a known monitoring scan 42 is performed, which is used to trigger the actual inspection scan 44. In this scan, images are captured in chronological order. The scan 44 is triggered when a predefined threshold value 46 (signal level, gray level, attenuation value or CT value) is exceeded in a defined region of interest (ROI, such as large blood vessels). The scan 44 in this case starts at a predefined delay after the predefined threshold 46 is reached. Scan 44 at time T S Start at and at time T E The end.

[0039] The central area of ​​the figure shows the signal level S (gray level, attenuation value or CT value) in the form of a timing chart. The administration of contrast agent (KM) causes the signal level S to rise and reach a predefined threshold at point 46. When the threshold value 46 is reached...

Abstract

The invention relates to a method for recording medical images of the human body or that of an animal. Said method consists of the following steps: scanning for acquiring data and signaling the start and / or end of a manual administration of a contrast medium in temporal relation to the scan for acquiring data.

Description

Technical field [0001] The invention relates to a method and a device for capturing medical images, particularly by means of computer tomography (CT) or magnetic resonance imaging (MRI). In particular, the present invention relates to capturing two-dimensional or three-dimensional images of the inside of the human or animal body, which images are specifically intended to show or show blood vessels. Background technique [0002] It is known to inject a contrast agent in order to improve the visualization of blood vessels. Medical imaging using contrast agents here has the following basic problem: achieving constant contrast enhancement over time or simultaneously with data acquisition in blood vessels or tissues, while specifically aiming to achieve contrast enhancement using the smallest possible amount of contrast agent. Contrast agents (such as radiation doses) have potentially adverse effects on patients, which is why it makes sense to keep the levels to a minimum. Cost is a...
