Team calls for 'village' approach for tackling breast cancer inequities
Researchers are calling for a "village" approach for tackling breast cancer disparities.

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
Ultrasonic features are tied to increased risk of tumor progression in patients with papillary thyroid microcarcinoma undergoing surveillance.
November 1, 2023
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.

PET/CT reveals new infections in ICU patients
By Will Morton
F-18 FDG-PET/CT is a valuable approach for diagnosing unknown infections in intensive care unit (ICU) patients.
February 21, 2025
There are several conceivable advantages of F-18 FDG PET/CT over conventional imaging. Image A and B showing an example of the distinctive capability of the F-18 FDG PET/CT. A shows a fusion image of F-18 FDG PET/CT and low-dose CT and B an high resolution chest CT of a patient with an Aspergillus infection. The suspected aspergilloma is concealed on the high resolution CT due to the lung fluids and consolidation. Image C and D (fusion image of F-18 FDG PET/CT and low-dose CT and low-dose CT only, respectively) are examples of the ability to image inflammation while no concurrent abnormalities are visualized, in this case prostatitis (red arrows). Image E, a maximized intensity projection of F-18 FDG PET, shows a patient with lung infections and multiple muscle abscesses after MRSA sepsis. This is an illustrative example of a relevant dissemination investigation.

LUS reliable for care strategies in infants with RDS
By Amerigo Allegretto
Lung ultrasound (LUS) scoring is reliable for determining whether preterm newborns need surfactant for suspected respiratory distress syndrome (RDS).
February 20, 2025
1Each lung has been split into three parts. Each area has been given a score between 0 and 3. Score values are shown in Ultrasonograms to match 4 different patterns. During a longitudinal scan with a high-resolution linear probe, pictures of patterns were taken. The scores are as follows: 0 means A pattern, 1 means B pattern, 2 means severe B pattern, and 3 means extended consolidation.

(B and C) Low uptake of Ga-68 PSMA-R2 in salivary and submandibular glands is also demonstrated. (D) Images show heterogeneous uptake of Ga-68 PSMA-R2 with varying degrees of intensity in multiple spine bone lesions (vertebral sclerotic lesion with intense PSMA-R2 expression at its periphery indicated with red arrow).

CT best for diagnosing suspected wooden foreign objects in the eye
By Kate Madden Yee
CT imaging is best for diagnosing suspected intraorbital wooden foreign bodies, although MR imaging does offer valuable supplementary information.
February 20, 2025
A 7-year-old boy, imaged 15 hours post-injury. Axial CT images with soft tissue windows (WW/WL=350/50) (a) reveal a rod-shaped foreign body (white arrow) situated along the course of the right inferior rectus muscle. The soft tissue window demonstrates that the foreign body exhibits attenuation similar to orbital emphysema. Axial CT images (WW/WL=1000/−200) at the same level (b) show that the attenuation of the foreign body (white arrow) is markedly different from that of the air in the sinuses.
