Breast cancer screening in Austria: A new approach to early detection
VIENNA - With the exception of some local pilot projects, early breast cancer detection in Austria has depended upon opportunistic breast cancer screening in individual radiology practices. But in October, organized mammography screening will be introduced, utilizing the robust existing infrastructure of local radiology practices. Performing screening exams in locations all over the country should help achieve high rates of participation.

Schematic diagrams and representative images of different distribution patterns of region lymph nodes detected at CT. (A) Vascular distribution pattern: All regional lymph nodes detected at CT have regular borders and are distributed along the vessels (arrowheads). (B-E) Coronal CT images in a (B) 34-year-old woman, (C) 51-year-old man, (D) 37-year-old man, and (E) 40-year-old man with microsatellite instability-high (MSI-H) colon cancer show multiple clear lymph nodes distributed along the supplying arteries or draining veins (arrowheads). (F) Jammed cluster pattern: At least three lymph nodes with blurred margins and clustered (circle). (G-I) Coronal CT images in a (G) 29-year-old man, (H) 35-year-old man, and (I) 67-year-old man and (J) axial CT image in a 43-year-old man with MSI-H colon cancer show several lymph nodes with blurred margins and clustered (circle). Movies 1-4 provide more details. (K) Fused pattern: Several poorly defined lymph nodes clustered and fused together (arrow). (L-O) Coronal CT images in a (L) 63-year-old woman, (M) 59-year-old man, (N) 49-year-old woman, and (O) 73-year-old man with MSI-H colon cancers show several lymph nodes fused (arrow).

CT
CT effective for tracking colon cancer lymph node distribution
Images depict a 65-year-old patient with contralateral second breast cancer 6.3 years after right mastectomy. (A) Left craniocaudal and (B) mediolateral oblique mammograms assessed as benign. (C) The AI algorithm outlined a lesion with a score of 31 on the craniocaudal view. (D) A supplemental axial ultrasound scan, which was obtained on the same day as the mammogram, shows an irregular hypoechoic mass (arrows) in the left upper central breast. (E) Preoperative sagittal contrast-enhanced T1-weighted MRI scan shows the corresponding enhancing mass (arrow) in the left upper center. The mass was proven to be ductal carcinoma in situ.
