Group name

Imaging and Tracing

Senior research group

The Imaging and Tracing group focuses on the preclinical development of novel radiopharmaceuticals and molecular imaging agents for the comprehensive evaluation of pathological conditions and monitoring of disease progression and therapy in vivo. This includes the development of cutting-edge radiolabelling and radioanalytical strategies, and the evaluation of novel candidate tracers in vitro and in vivo using a wide range of imaging approaches. We also develop small animal models of various diseases, particularly infections and cancer.

We perform non-invasive multimodal imaging and image analysis for the observation of various disease and biological models in living systems. Our state-of-the-art instrumentation currently includes an extensive suite of imaging modalities, such as positron emission tomography (PET), single photon emission computerized tomography (SPECT), computerized tomography (CT), magnetic resonance imaging (MRI), optical imaging (including bioluminescence and fluorescence ranging from the green to near-infrared region) and ultrasound (US). In addition, fully equipped radiochemistry laboratory and dedicated housing for animals undergoing longitudinal imaging studies is available.

Project: Multimodal imaging methods for testing bioactive molecules in vivo
Supervisors: Petřík Miloš Ph.D., Nový Zbyněk Ph.D.
Available: 2
Intended for: Doctoral training
Summary:

The student will employ modern in vivo imaging techniques namely positron emission tomography, single-photon emission tomography, computed tomography and optical imaging in order to elucidate effect of novel anticancer or antimicrobial agents. The other part of the project will be assessment of novel radiotracers directed towards targets expressed by tumour cells or by microbial pathogens. Daily work routine will include all proper working steps common in radiopharmacy, i.e. starting with gaining an radioisotope from dedicated source, radiolabelling of selected compound, quality control (HPLC/TLC), stability tests, in vitro testing of biological properties and finally in vivo procedures (biodistribution, static/dynamic imaging). Expected previous education includes medicine, pharmacy, pharmacology or related field.
