The team from Çukurova University, Türkiye — an experienced clinical user of PLANET® Dose — will present five posters at the 6th European Congress for Medical Physics (ECMP 2026) in Valencia. The work was carried out in collaboration with Oncosia Scientific and covers voxel-based dosimetry in Y-90 selective internal radiation therapy (SIRT) and Lu-177 DOTATATE therapy.
The posters, authored by Yılmaz Ahmet, Karagedik Bayram Çağlar, Polat Ercan, Beykan Schürrle Seval, and Güney İsa Burak:
Evaluation of Uncertainty and Spatial Resolution Effects in Voxel-Based Y-90 TARE Dosimetry: A Comparative SPECT/CT vs. PET/CT Analysis
Impact of Dual Segmentation on Voxel-Based Renal Dosimetry in Lu-177 DOTATATE Therapy
The Effect of Imaging Time Point Selection on Voxel-Based Dosimetry in Lu-177 DOTATATE Therapy: Optimization of Single and Two Time-Point Strategies
Intra-Tumoral Cold Spots as Predictors of Local Progression After Y-90 Radioembolization: A Voxel-Based Dosimetry Study
Modality-Dependent Bias and Variability in Voxel-Based Y-90 Dosimetry: A Paired SPECT/CT vs. PET/CT Analysis in the Same Patients
All five abstracts are published in full on DOSIsoft's ECMP 2026 poster page: PLANET Clinical Insights at ECMP 2026 →
Together, the five works examine how imaging modality, time-point selection, and segmentation approach affect the accuracy and reproducibility of voxel-level dose calculations — questions directly relevant to departments moving from organ-level to voxel-based dosimetry in SIRT and Lu-177 therapy.
The studies were conducted using PLANET® Dose by DOSIsoft, for which Oncosia Scientific is an authorised distributor and implementation partner in Germany and Türkiye.
