Method for imaging lesion and lesion imaging system
First Claim
1. A lesion-imaging method using a system furnished with a syringe through which contrast medium is introduced, a control unit for operating the syringe to control contrast-medium infusion quantity, and a device for capturing images of a lesion area in a patient into whom contrast medium has been infused through the syringe, the method comprising:
- a step of infusing a small amount of contrast medium from the syringe for a time Tn, and, using the image-capturing device, measuring changes in blood contrast-medium concentration in the patient'"'"'s lesion area;
a step of summing, over a period Tc, required to infuse a diagnostic-effective amount of contrast medium, data based on the change in blood contrast-medium concentration during the time Tn, to predict contrast effect for the period Tc; and
a step of displaying the predicted contrast effect and prompting determination of whether to change the contrast-medium infusion conditions.

Abstract
The invention provides a method for imaging a lesion area that includes a process of infusing a small amount of contrast medium from the syringe for a time Tn and using an image capturing device to measure a change in blood contrast medium concentration, a process of summing data that are based on the change in blood contrast medium concentration during the time Tn over a period of a required infusion time Tc for an amount of contrast medium necessary for diagnosis, to predict the contrast effect during the required infusion time Tc, and a process of displaying the predicted contrast effect and urging determination of whether or not to change the infusion conditions of the contrast medium.

3. A legion imaging system comprising a syringe through which contrast medium is introduced, a control unit for controlling the quantity of contrast medium infused through the syringe, and a device for capturing images of a lesion area in a patient into whom contrast medium has been infused through the syringe, wherein the control unit stores a program for:
-
infusing a small amount of contrast medium from the syringe for a time Tn;
using the image-capturing device, measuring changes in blood contrast-medium concentration;
summing, over a period Tc, required to infuse a diagnostic-effective amount of contrast medium, data based on the change in blood contrast-medium concentration during the time Tn, to predict contrast effect for the period Tc;
displaying the predicted contrast effect and prompting determination of whether to change the contrast-medium infusion conditions.
