Atlas of Gastrointestinal Imaging Figure 1.3.3 Side branch IPMN

FIGURE 1.3.3 Side branch IPMN. Coronal reformatted CT image (A) shows cystic dilatation of a single side branch in the pancreatic head (arrow). On subsequent ERCP (B), contrast opacifies the same dilated side branch. Coronal T2-weighted SSFSE MR image (C) from a second patient shows a cluster of cystic lesions in the pancreatic head, which on MRCP (D) appears as a branching multicystic structure that communicates with, but does not directly involve, the main pancreatic duct. Contrast-enhanced CT (E) and intraoperative US (F) images from a third patient show a more nonspecific cystic lesion involving the pancreatic tail. Contrast-enhanced CT (G), T2-weighted MR (H), and MRCP (I) images from a final patient show a multicystic-appearing side branch IPMN involving the uncinate process.

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.

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.

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.

Example of Percentile Nomogram With Age-Adjusted BAC Quartiles. (A) Mammogram of a 56-year-old woman. There is evident BAC (pink arrow). This was quantified as a BAC score of 30 using the cmAngio tool. (B) Nomogram indicating that a BAC score of 30 places a 56-year-old woman within the 50th to 75th percentile for her age.
