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.

Delaware leads the U.S. in the incidence of triple-negative breast cancer and advanced breast cancer diagnosed at a younger age, ChristianaCare researchers highlighted. 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

By Amerigo Allegretto

Ultrasonic features are tied to increased risk of tumor progression in patients with papillary thyroid microcarcinoma undergoing surveillance.

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.

Screenshots of the imaging viewer interface before (a-b) and after (c-d) having clicked “Review placed markers.” The “Case assessment widget” has been magnified in (b,d). One marker was incorrectly placed (c), which is signified with a red cross. One nodule was not identified (c) and was highlighted by a yellow circle through the mouse over function in the “List of synthetic lesions.” Image courtesy of the British Journal of Radiology.
