X-ray isolation keeps patients and staff safe during COVID-19
The COVID-19 pandemic has forced many radiology facilities to find innovative ways to do their work while keeping patients and staff safe. In a new paper, Australian researchers describe their technique for acquiring x-rays through glass, enabling x-ray equipment to be isolated outside patient rooms.

CT-based nomogram aids in managing advanced ovarian cancer
By Amerigo Allegretto
Researchers have developed a CT-based nomogram that could assist in managing advanced ovarian cancer.

Calculation of radiological peritoneal cancer index (rPCI) adapted from Sugarbaker et al (1). (a) Coronal CT showing regions 0–8. Vertical lines are drawn along the right and left midclavicular line and the horizontal lines along the costal margin and the iliac crests. (b) Coronal CT showing regions 9 to 12. The vertical and the horizontal lines are through the umbilicus divide the small bowel and mesentery into proximal and distal jejunal and ileal regions.

MRI reveals occurrence of placental contractions
By Kate Madden Yee
Characterizing these contractions could help clinicians better understand the placenta's function.
April 29, 2026
Uterine and placental changes during an example placental contraction. The top row shows axial MRI images at selected times points before, during and after a placental contraction (indicated by vertical lines on the graph below) with segmentations shown below. Changes in placental and non-placental volumes, wall areas and placental R2* (all measured across the whole volume of the uterus, not just the single slice shown) are plotted underneath. The legend indicates the colors used for the lines in the plots and the regions indicated in the segmentation.
Lu-177 PSMA-SPECT/CT predicts survival in mCRPC
By Will Morton
Lu-177 PSMA-617 SPECT/CT total tumor volume complete response at six weeks associated with overall survival.
April 29, 2026
Quantification of total tumor volume (TTV) at lutetium-177 prostate-specific membrane antigen (PSMA)–617 SPECT/CT shows heterogeneous TTV responses between dose 1 (Cycle #1) and dose 2 (Cycle #2) in participants with metastatic castration-resistant prostate cancer. Posttherapy coronal attenuation-corrected noncontrast SPECT/CT maximum intensity projection images demonstrate (A) near-complete response in a 76-year-old man, (B) complete response in an 83-year-old man, (C) partial TTV reduction (not complete response) in a 69-year-old man, and (D) TTV increase (i.e. progressive disease) in a 74-year-old man. Blue-shaded regions represent semiautomatically segmented PSMA-avid tumor volume, with associated TTV values given at the bottom of each panel. The gradient bar shows standardized uptake value (SUV) from 0 to 5.
