Brachytherapy dose calculation just got better
Everyone agrees that patients undergoing radiotherapy usually do not resemble uniform water spheres with a 30-cm diameter. Nevertheless, this is the common assumption of radiation dose calculations used for brachytherapy.

FDG-PET/CT sharpens surveillance after colorectal liver metastasis treatment
By Claudia Tschabuschnig
A Dutch study found that adding metabolic imaging to contrast-enhanced CT improved early detection of local tumor progression after liver ablation or resection, including disease missed by CT alone.

SPECT/CT viable over PET/CT for high-risk prostate cancer staging
By Will Morton
Considering its broader accessibility, Tc-99m MIP-1404 CZT SPECT/CT may represent a practical alternative for primary staging.

Maximum intensity projection of Ga-68 PSMA-11 PET/CE-CT (A), Tc-99m MIP-1404 CZT SPECT/CT (B) and Tc-99m HDP CZT SPECT/CT (C) imaging. Ga-68 PSMA-11 PET/CE-CT and Tc-99m MIP-1404 CZT SPECT/CT showing tracer uptake in lymph nodes below the iliac bifurcation and above, paraaortic and left supraclavicular, bone uptake in the right proximal femur and right scapula (arrows). Tc-99m HDP CZT SPECT/CT did not show any uptake suspicious for metastatic disease. No sclerotic lesions suspicious of metastases were detected by the CT component in any of the studies. Fusion axial imaging of Ga-68 PSMA-11 PET/CE-CT (D) and Tc-99m MIP-1404 CZT SPECT/CT (E) showing uptake in lymph nodes in the left pelvic area below the iliac bifurcation (arrows). Fusion axial imaging of Ga-68 PSMA-11 PET/CE-CT (F) and Tc-99m MIP-1404 CZT SPECT/CT (G) showing uptake in the right proximal femur, not detected by Tc-99m HDP CZT SPECT/CT (H), (arrows).

CT dose, not FDG, drives chromosome damage during PET/CT
By Claudia Tschabuschnig
The findings suggest that standard-dose CT should be reserved for clearly justified diagnostic indications.
