Article Synopsis
- The study evaluates the Kaiser score (KS) as a decision-making tool for identifying breast lesions using contrast-enhanced mammography (CEM) and compares its effectiveness to magnetic resonance imaging (MRI).
- 275 patients with breast masses were analyzed, categorized into benign or malignant based on pathology, and imaging characteristics were statistically compared between CEM and MRI.
- Results showed significant differences in various imaging features between benign and malignant lesions, with KS outperforming BI-RADS in diagnostic accuracy for CEM.
Rationale And Objectives: The prognosis of ductal carcinoma in situ with microinvasion (DCISM) is more similar to that of small invasive ductal carcinoma (IDC) than to pure ductal carcinoma in situ (DCIS). It is particularly important to accurately distinguish between DCISM and DCIS. The present study aims to compare the clinical and imaging characteristics of contrast-enhanced mammography (CEM) and magnetic resonance imaging (MRI) between DCISM and pure DCIS, and to identify predictive factors of microinvasive carcinoma, which may contribute to a comprehensive understanding of DCISM in clinical diagnosis and support surveillance strategies, such as surgery, radiation, and other treatment decisions.

In recent years, close-range photogrammetry based on smartphone has attracted attention from researchers due to its low cost and non-destructive characteristics. However, such methods have specific requirements for camera angle and distance during shooting, and pre-shooting operations such as camera calibration and placement of calibration boards are necessary, which could be inconvenient to operate in complex natural environments.

Article Synopsis
- Carbonized traditional Chinese medicine (TCM) has been used for over 2000 years in treating bleeding syndromes but lacks specific quality standards and research on quality control.
- This study focused on Carbonized Typhae Pollen (CTP), highlighting its benefit in blood stasis and bleeding control.
- A new quality control model called Gradient-based Discriminant Analysis (GDA) was developed, demonstrating superior accuracy and stability over traditional methods, ensuring better quality control for carbonized TCM and its effectiveness in clinical settings.
Carbonized ginger, a type of charry herb, has been used as a hemostatic medicine since ancient times. However, there are some serious problems such as inhomogeneous heating and emitting smoke during processing with traditional stir-frying method. To investigate the feasibility to obtain carbonized ginger by stir-frying with sand instead of stir-frying method.

Primary trachea-bronchial ES/pPNET is very rare. The most common pulmonary ES is due to a metastasis.
View Article and Find Full Text PDFPropose: To explore the value of unmeasurable enhancement pattern of residual cavity in predicting survival at early stage after gross-total resection in high-grade glioma (HGG) patients.
Methods: This retrospective study enrolled consecutive 51 HGG patients with unmeasurable enhancement who underwent gross-total resection followed by concurrent chemoradiotherapy and adjuvant chemotherapy. We evaluated the enhancement patterns of residual cavity on contrast-T1WI made within 1 month after tumor resection (20 ± 3 days).
