Ultrafast breast MRI determines malignant from benign markers

By Amerigo Allegretto

Ultrafast breast MRI can differentiate between markers associated with malignancy.

April 9, 2025

(A) Ultrafast MR image obtained 14 seconds after aortic enhancement shows 0.4-cm focus (arrow) in the left breast at 3-o’clock position, 4.5 cm from index cancer (not shown). (B) Ultrafast MR image obtained 23 seconds after aortic enhancement shows wash-in (arrow) of background parenchymal enhancement (BPE). (C) and (D) On first standard postcontrast subtraction MR images, focus (arrow, C) and BPE (arrow, D) are indistinguishable. MRI-guided biopsy of focus yielded grade 2 invasive lobular carcinoma.

CT effective for tracking colon cancer lymph node distribution

By Kate Madden Yee

Using CT to track lymph node distribution in colon cancer patients is more effective at identifying metastasis than conventional testing.

April 8, 2025

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).

AI bests rads in finding breast cancer in women with personal history

By Amerigo Allegretto

AI may have a role in finding contralateral disease in women with a personal history of breast cancer.

April 8, 2025

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.
