Multimodal preclinical imaging.
One scanner. One session.

PET, SPECT, and CT — acquired simultaneously, in the same animal, at sub-millimeter resolution. Two routes below: explore the scanner that makes it possible, or dive into the underlying physics.

The VECTor/CT Scanner

Our MILabs VECTor/CT — one of the few preclinical scanners worldwide capable of acquiring PET and SPECT simultaneously, at sub-millimeter resolution. Full technical specs, isotope compatibility, sample scans, and applications.

  • Mouse and rat protocols supported
  • True dual-isotope SPECT — two tracers in one scan
  • Supports 25+ radioisotopes
  • Example studies and representative images

Principles of PET & SPECT

A clear, concise introduction to nuclear molecular imaging — the physics behind PET and SPECT, how each modality works, and how they compare to MRI and optical imaging. Recommended reading before workshops or starting a project.

  • How PET detects positron annihilation
  • How SPECT detects gamma photons
  • When each modality is the right choice
  • Comparison with MRI, CT, and optical imaging

What each one is good at

PET, SPECT, and CT are all available on a single scan session. They complement each other — molecular function from PET and SPECT, anatomical context from CT.

PET
Positron Emission Tomography
Functional · molecular
Detects two gamma rays released when a positron annihilates with an electron. Excellent quantification, ideal for tracking dynamic processes like drug pharmacokinetics.
ResolutionSub-millimeter
Best forDynamic PK
Isotopes18F · 68Ga · 89Zr
SPECT
Single Photon Emission CT
Functional · molecular
Detects gamma photons directly from a radiotracer. Wider range of compatible isotopes than PET and supports true dual-isotope studies — two tracers, same animal, same scan.
ResolutionSub-millimeter
Best forDual-tracer studies
Isotopes99mTc · 111In · 177Lu
CT
Computed Tomography
Anatomical · structural
X-ray-based anatomical imaging — provides the structural context for PET and SPECT data. Used for organ localization and attenuation correction in the same scan session.
RoleAnatomical reference
Best forOrgan localization
CouplingAuto-registered
