Abstract
Description
Die Erfindung betrifft einen Katheter für magnetresonanztomographische Untersuchungen, der in MR-tomographischen Schnittbildern sichtbar gemacht werden kann und mit dem sich anatomische Strukturen wie Blutgefäße signalintensiv darstellen lassen.The invention relates to a catheter for magnetic resonance imaging examinations, which can be made visible in MR tomographic sectional images and with which Have anatomical structures such as blood vessels displayed in a signal-intensive manner.
Die Magnetresonanztomographie ist ein zunehmend verbreitetes bildgebendes Verfahren mit starken Magnetfeldern ohne Strahlung und basiert in erster Linie auf gezielter Anregung und Messung von Wasserstoffatomen unter Resonanz. Dabei hängt die Signalintensität wesentlich von der Anzahl der am Meßort vorhandenen Wasserstoffatomkerne ab, so daß sich unterschiedliche Wasserstoffdichten im MR-tomographischen Schnittbild in entsprechende Signalintensitätsstufen differenzieren lassen. Ist die Anzahl dieser Wasserstoffatomkerne in einem Körper jedoch nur gering, so ist auch das Signal dementsprechend schwach und die Meßstelle oder das Meßobjekt ist im Schnittbild nur schwach oder gar nicht zu erkennen. Dies stellt zugleich ein großes Problem konventioneller Katheter dar, da diese aufgrund ihrer Materialbeschaffenheit keine Signalintensität hervorrufen und damit deren eindeutige Lage und Abbildung im MR-tomographischen Schnittbild bzw. im darzustellenden Körperteil nicht sichtbar gemacht werden kann.Magnetic resonance imaging is an increasingly common imaging technique with strong magnetic fields without radiation and is primarily based on targeted excitation and measurement of hydrogen atoms under resonance. The signal intensity depends on this depends essentially on the number of hydrogen atom nuclei present at the measuring location, so that different hydrogen densities in the MR tomographic sectional image in corresponding Have signal intensity levels differentiated. Is the number of these hydrogen atom nuclei in However, if the body is only slight, the signal is correspondingly weak and the The measuring point or the measuring object is only weakly or not at all recognizable in the sectional view. This also represents a major problem with conventional catheters, because of their Material properties do not cause signal intensity and thus their clear location and not in the MR tomographic sectional image or in the body part to be displayed can be made visible.
Mit steigender Indikationsstellung in der MR-Diagnostik und Therapie, wird die Forderung nach visualisierbaren Kathetern und Körperteilen wie z. B. von Herzgefäßen immer deutlicher.With increasing indications in MR diagnostics and therapy, the demand for visualizable catheters and body parts such as B. of cardiac vessels more and more clearly.
Die Erfindung hat sich der Lösung dieser Aufgabe gestellt, durch die Verwendung von Kathetern, die mit signalgebenden Medien versehen werden können oder den Transport dieser signalgebenden Medien in einen Körper ermöglichen.The invention has solved this problem by using Catheters that can be provided with signaling media or the transport of these enable signaling media in a body.
Die Erfindung löst das Problem durch die Unterbringung oder Durchströmung signalgebender Medien in speziell gestalteten Katheterschläuchen. Die signalgebenden Medien können dabei in Hohlräumen oder direkt auf der Oberfläche der Katheterschläuche angeordnet sein. Zum Durchströmen des signalgebenden Mediums durch einen Katheter bis zum Untersuchungsort, befindet sich mindestens eine Zu- und Abflußöffnung am Katheter.The invention solves the problem by accommodating or flowing signal Media in specially designed catheter tubes. The signaling media can do this be arranged in cavities or directly on the surface of the catheter tubes. To the Flow through the signaling medium through a catheter to the examination site, there is at least one inlet and outlet opening on the catheter.
