    摘要: Methods and systems for infusing a cooled infusate to a target location in a patient are described. A temperature of the blood and infusate admixture upstream of the catheter as well as at other locations along the catheter may be monitored and a feedback system utilized to control the volume, temperature, and/or infusion rate of the infusate so as to achieve a predetermined temperature at the target location. Control may also be based on the patient's native vessel flow rate. The system may monitor or calculate hematocrit upstream of the catheter and adjust infusion so as to provide sufficient oxygenation of the blood and infusate admixture. The system may also monitor reflux of the infusate past a distal end of the catheter and reduce infusion upon the detection of reflux.

    摘要: A method for producing an image of a blood vessel in a patient utilizing temperature sensitive MRI measurement. The method includes introducing a fluid in a blood vessel, obtaining magnetic resonance information from the blood vessel, and determining a magnetic resonance parameter using the magnetic resonance information. The method further includes using the magnetic resonance parameter to determine a temperature differential in the blood vessel and producing an image of the blood vessel based on the temperature differential. Systems for producing an image of a blood vessel in a patient using temperature sensitive MRI measurements are also provided.

    摘要: A method and apparatus for determining a temperature differential at a portion of a patient's body utilizing temperature sensitive MRI measurements. A diagnostic fluid bolus is administered into a blood vessel of the patient, wherein the diagnostic fluid bolus has a diagnostic fluid bolus temperature waveform. MRI measurements are used to determine the thermodiluted temperature waveform of the diagnostic fluid bolus at a target site in the body spaced away from the administration site. The temperature differential may be used to determine a cardiovascular parameter.
