Heterogeneity quantification

Tumors are spatially and temporally heterogeneous. MILabs’ preclinical imaging systems offers the unprecedented ability to dynamically image tumors with SPECT and PET at sub-mm resolutions, even down to 0.15 mm resolution for SPECT. This unique ability enables in vivo quantification of physiological or biological factors that influence tumor response [1–4].

Phenotyping

The physical tumor microenvironment contributes significantly to carcinogenesis, cancer progression and metastatic dissemination. With MILabs’ exclusive 3D SPECT/CT autoradiography technique, the labor intensive and time consuming method of serial section and traditional immuno-histochemical staining for protein profiling is becoming a thing of the past. Moreover, for in vivo applications, its multi-parametric simultaneous PET/SPECT imaging of co-injected tracers enables to uncover novel imaging characteristics linked to tumor phenotypes [5,6].

Tumor vasculature

Factors that impede drug delivery include the complicated, tortuous nature of tumor vasculature. The MILabs’ ultra-high resolution Dynamic Contrast-Enhanced CT (DCE-CT) feature makes it possible to analyze temporal dynamic changes in perfusion parameters in tumor tissue. In addition, simultaneous imaging of vascularity and hypoxia with Concurrent PET/SPECT can differentiate hypervascular from hypovascular tumors, thus guiding the decision for applying antiangiogenic, anti-vascular, or anti-hypoxia therapies [7].

Radiogenomic genotypes

Radiogenomics analysis reveals gene-expression patterns which often underlay prognostic radiomic signatures, hence providing further insight into intra-tumoral heterogeneity. MILabs’ Hybrid Optical sub-system imaging capability enables imaging of multi-modal reporter gene/reporter probe system thus allowing one to select an appropriate imaging modality for a particular application, cross-validate information captured by each imaging modality and facilitate translation of preclinical imaging techniques to the clinic [8,9, brochure].

Radiotherapy profiling

Targeted radionuclide therapy is one of the most intensively developing directions of nuclear medicine. MILabs’ offers the most versatile preclinical imaging system ever for evaluating strategies to improve radiotherapy, all with the aim of increasing the effect on the tumor or decreasing the effects on normal tissues. Virtually any α-, β-, or Auger electron-emitter with gamma-rays below 950 keV can be imaged with the system and its therapeutic effects quantified. Now you can tailor your irradiation therapy to tumor type and heterogeneity, as well as the inhomogeneity of the radionuclide distribution, pharmacokinetics, etc… No longer will your imaging system limit your options [10–13].
