<p>A method is proposed for detecting cancer and particularly malign tumors in a person by using the NMR spectrum of blood plasma. In a recorded spectrum the resonances are determined and for these values mathematically defineable properties are calculated such as in the simplest case the height of the resonance and the value of the width of the resonance at half height. Advantageously at least two different mathematically defineable properties are used and the corresponding values are considered as entered in a multidimensional space. In this there are defined regions of expected and not expected malignancy and if the values are located within either region the corresponding conclusion can be obtained in regard of the fact if the person has or has not cancer. If the values are located outside these regions a safe conclusion cannot be obtained. Further, as a criterion can be used the difference and/or the quotient of the values determined for some characteristic property of these resonances. As a characteristic property the peak value, the width at half height of the area can be chosen. Instead of the width at half height the value can be used which is obtained by first determining the total area of a resonance over a particular level and by dividing this area by the height of the resonance line over the underlying resonances.</p> |
