  • Publication number: 20130211256
    Abstract: The invention relates to medical monitoring apparatuses, methods, and computer programs for determining power or work as a function of time for individual myocardial segments based on strain and pressure measurements. Compared to prior art determinations of determination of mechanical power or work for individual segments, the invention is advantageous as it provides such determination solely from a pressure measurement or estimate and a measurement of strain, preferably by echocardiography, such as speckle tracking ultrasound imaging. This allows a fast, easy and non-invasive determination with high temporal and spatial resolution. A number of indices for segment work can be calculated which can be used as markers for the individual segment function as well as for a selection of patient for CRT.

  • Patent number: 8428327
    Abstract: The invention relates to segmenting blood vessels in perfusion MR images, more particularly, the invention relates to automated vessel removal in identified tumor regions prior to tumor grading. Pixels from a perfusion related map from dynamic contrast enhancement (DCE) MR images are clustered into arterial pixels and venous pixels by e.g. a k-means class cluster analysis. The analysis applies parameters representing the degree to which the tissue entirely consists of blood (such as relative blood volume (rBV), peak enhancement (?R2max) and/or post first-pass enhancement level (?R2p)) and parameters representing contrast arrival time at the tissue (such as first moment of the area (fmAUC) and/or contrast arrival time (T0)). The artery and venous pixels are used to form a vessel mask. The invention also relates to a computer aided diagnostic (CAD) system for tumor grading, comprising automated tumor segmentation, vessel segmentation, and tumor grading.

  • Patent number: 8233965
    Abstract: An embodiment of the invention is to make possible a non-invasive grading of a tumor based on parameters determined from a frequency distribution (histogram) of values in a map representing cerebral blood volume (CBV) or cellular metabolism in the tumor. The method is especially applicable to brain tumors such as gliomas where histological grading is difficult. The invention provides a precise and consistent grading since it relies on values selected from the whole tumor (not just from hot spots); since it takes the diversity or heterogeneity of the vascularization into account by analyzing the frequency distribution (not just a mean value); and since it involves and allows for a more automated procedure wherein any subjective contributions from human operators is not critical to the resulting grading. CBV maps may be obtained by perfusion imaging using MRI or CT scanning. Cellular metabolism maps may be obtained from a glucose metabolism map obtained by positron emission tomography (PET).

  • Publication number: 20120172242
    Abstract: The present inventors here present a novel strategy for identification of RNA transcript variants and demonstrate that these can be correlated to disease states in mammals such as cancer. In particular, the transcript variants show prevalence and specificity to cancer, and thus also show clinical applicability in e.g. cancer diagnostics and prognostics, treatment and therapeutics. The present inventors have identified RNA transcript variants of VNN1 that can be used as biomarkers. The RNA transcript variant may also be used as biomarkers for diagnosing, prognosing, and/or monitoring a cancer.

  • Publication number: 20110257519
    Abstract: The invention provides a method, an image analysis software product, and a system for medical imaging analysis for estimating contrast agent extravasation in contrast agent based perfusion imaging such as MRI dynamic contrast enhanced (DCE) imaging, and in particular correction, compensation, or visualization of extravascular leakage of contrast agent in tumors. According to the invention, the effect of extravasation is directly manifested in the tail part of an observed, apparent residue function, R?(t), obtained directly by de-convoluting the expression C(t)=R?(t)Cp?(t) with the arterial input function (AIF). A leakage rate or extravasation constant is determined directly from the tail part of the determined apparent residue function.

  • Publication number: 20110046488
    Abstract: The invention relates to a method and a post-operative care unit for analysing and quantifying an ultrasound tissue Doppler imaging (TDI) signal from a transducer fastened on the myocardium to obtain a parameter indicating regional cardiac ischaemia or correlates with global hypokinetic heart function. This has the advantage over manually operated probes that it can be automated and used continuously over long time. According to the method, a TDI signal trace corresponding to at least one of tissue velocity, strain or strain rate is extracted and correlated with an electrocardiogram to define subsections within a cardiac cycle in the extracted trace corresponding to the early systolic phase and the post-systolic phase. Then, a velocity, strain or strain rate is read in at least the post-systolic phase of the extracted trace, and a parameter which is a function of one of these readings and which indicates ischaemia or global hypokinetic function is generated.
