Mediso installs true theranostic TheraMAX SPECT/CT
2025.10.02.
Mediso completes the installation of an AnyScan ® TRIO-TheraMAX SPECT/CT（https://mediso.com/global/en/product/maximum-performance-theranostic-diagnostic-spectct/anyscansupsup-trio-spectct-theramaxsupsup） at the Department of Nuclear Medicine at Heidelberg University Hospital.
The system is specifically designed for the clinical needs of theranostic imaging. Its detectors and collimators are developed for Targeted Radionuclide Therapies carried out with radioisotopes emitting alpha and beta particles and have co-emission of high and ultra-high energy gamma photons that are more challenging to image than diagnostic 99m Tc. This requires maximized performance for quantitative imaging and dosimetry with theranostic isotopes (i.e. 177 Lu, 225 Ac, 212 Pb, 131 I) that is not available with current SPECT/CT systems.
“The TheraMAX expands the imaging capabilities of our department for radioligand therapy. We treat patients with a wide range of novel radiopharmaceuticals labelled with 177 Lu or 225 Ac, some of them as part of clinical trials for developing improved and more individualized patient care. In addition, the TheraMAX supports our department by increasing the capacity of our department for 99m Tc-PSMA scans for radioligand therapy inclusion” said Professor Dr. Clemens Kratochwil, lead physician at Department of Nuclear Medicine, University Hospital Heidelberg. ”First scans of patients treated with 225 Ac suggest that the duration of whole-body quantitative SPECT/CT may be reduced allowing image-based dosimetry”.
The TheraMAX is equipped with three, large surface detectors (up to 5x larger than 12-detector CZT systems) surrounding patients with complete angular coverage in 360°. The 15.9 mm thick NaI crystals ensure improved sensitivity for high energy photons, while the high-density sensor arrangement (123 PMT per detector head) allows high spatial resolution leading to PET-like image quality.
