Active thyroid surveillance effective, beneficial for older patients
A 58-year-old woman was diagnosed with ER-positive (Allred score 8) ILC in her right breast. Ultrasound and MRI found prominent lymph nodes in right axillary level I area, diagnosed as metastasis on ultrasound-guided fine-needle aspiration. F-18 FES-PET/CT showed a positive mass in right breast (white arrow; SUVmax, 5.6) and multiple F-18 FES–positive lymph nodes in right axillary level I, II, and II/III junction areas (red arrows; SUVmax, up to 12.2). In addition, a small F-18 FES-positive lymph node was observed in the right second internal mammary area (red circles; SUVmax, 1.8). However, biopsy could not be performed because it was too small and not visible on ultrasound; the clinician decided to include internal mammary lymph node in treatment field for adjuvant radiotherapy. The patient underwent lumpectomy with ALN dissection, with five metastases being identified in 13 lymph nodes dissected, and is scheduled to receive adjuvant chemotherapy, radiotherapy, and endocrine therapy.

AI model predicts scoliosis spinal curve progression
By Will Morton
A deep-learning AI model shows promise for predicting spinal curves in individuals with adolescent idiopathic scoliosis.
November 3, 2023
Three regions of interest (ROI) were selected and processed for training from each original radiograph. The leftmost image is the original coronal view radiograph. The original radiograph was passed through the CLAHE algorithm to enhance image brightness and contrast. The three crop boxes outlined by red dotted lines illustrate the three crops generated for model training. Crop 1 selects the ROI for the whole-spine region according to coordinates exported by AlignProCARE. Crops 2 and 3 select the ROIs for the upper and lower end vertebra of the major curvature. All ROIs were subsequently resized into 256 × 256 for Crop 1 and 50 × 50 for Crop 2 and 3. Crop 1 ROI was additionally multiplied by a Gaussian mask to amplify the signal of the vertebrae.

Areas of higher intensity, which are visualized in this map with brighter shades of red, have higher historical rates of triple-negative breast cancer diagnosed at an advanced stage among women younger than 50 years relative to other areas within New Castle County, Delaware.
Ultrasound features tied to thyroid microcarcinoma tumor growth

Progression of hypervascular tumor with lymph node metastasis in a 64-year-old male participant with papillary thyroid microcarcinoma. (A-C) Baseline ultrasound images. (A) Transverse gray-scale image shows a solid hypoechoic thyroid nodule (arrow) with a maximal diameter of 7 mm. (B) Color Doppler image shows hypervascularity, represented by increased vascularity above that of normal thyroid parenchyma (arrows). (C) Transverse gray-scale image shows a small, probably benign lymph node at left level IV (arrow). (D) Transverse ultrasound image at 12-month follow-up demonstrates a suspicious lymph node (arrow) with increased shortest diameter and punctate echogenic foci (arrowhead). Subsequent fine-needle aspiration for this level IV lymph node revealed a metastatic thyroid papillary carcinoma. Image courtesy of Radiology.
