AI Article Synopsis
- The study compares the effectiveness of different digital mammography techniques, specifically one-view mediolateral (MLO), one-view craniocaudal (CC), and two-view digital breast tomosynthesis (DM-DBT), in characterizing breast lesions.
- Four radiologists evaluatedthese techniques independently on a group of 138 women, confirming their findings through pathology.
- Results indicated that while single MLO and CC views yielded similar outcomes, two-view DM-DBT showed significant benefits, particularly for junior radiologists, highlighting its importance for less experienced readers in identifying breast cancer lesions.
Article Abstract
Purpose: To compare the performance in breast lesion characterization of one-view mediolateral (MLO) digital mammography plus digital breast tomosynthesis (DM-DBT) versus one-view craniocaudal (CC) DM-DBT versus two-view DM-DBT.
Materials And Methods: The institutional review board approved this retrospective study conducted on 138 women from the population of a previous prospective multicenter study, with 69 consecutive patients with benign or high-risk lesions and 69 randomized patients with breast cancer, all confirmed at pathology. Four radiologists (two senior and two junior) blinded to the clinical, mammographic and pathological data independently reviewed the MLO DM-DBT views, the CC DM-DBT views and the MLO + CC DM-DBT views using the American College of Radiology Breast Imaging-Reporting and Data System criteria for index lesion characterization. Areas under the receiver were calculated and compared for each reader and imaging protocol.
Results: No significant differences in breast cancer characterization were observed between single MLO and CC views for all the readers. The added value of a second view was statistically significant for characterization in pooled data and for junior readers but not for senior readers (p ranging from 0.15 to 0.57 depending on the view and the senior reader). Finally, in 4 breast cancer cases, lesions were only detectable on the CC DM-DBT view in two cases and on the MLO DM-DBT view in the two other cases.
Conclusion: Our results support the use of two-view DM-DBT for breast lesion characterization when the readers are inexperienced. There is no significant difference between CC and MLO views when diagnosis is performed with one view.

Objective: To characterize structural integrity of the lumbosacral enlargement and conus medullaris within one month after spinal cord injury (SCI).
Methods: Lumbosacral cord MRI data were acquired in patients with sudden onset (<7 days) SCI at the cervical or thoracic level approximately one month after injury and in healthy controls. Tissue integrity and loss were evaluated through diffusion tensor (DTI) and T2*-weighted imaging (cross-sectional area [CSA] measurements).

Recent outbreaks of PRRSV in live attenuated vaccine-immunized pig farms in Tianjin, China have raised questions about the etiological characteristics and pathogenicity of the PRRSV variant, which remains unknown. In this study, a multiple lineages recombinant PRRSV strain named TJ-C6, was isolated and identified. Phylogenetic trees and genome homology analyses revealed that TJ-C6 belonged to lineage 1.

The term verruciform acanthotic vulvar intraepithelial neoplasia (vaVIN) was coined to describe HPV-independent p53-wildtype lesions with characteristic clinicopathologic characteristics and association with vulvar squamous cell carcinoma (vSCC). We aimed to expand on the molecular landscape of vaVIN using comprehensive sequencing and copy number variation profiling. vaVIN diagnosis in institutional cases was confirmed by a second review, plus negative p16 and wildtype p53 by immunohistochemistry.

Cystic echinococcosis (CE) is a zoonotic disease caused by sensu lato, the metacestode of a tapeworm parasite of high medical importance. Infection of the parasite leads to the development of echinococcal cysts, and the spleen is a rarely infected organ. A 46-year-old woman who was born and who resides in Sardinia, Italy, was referred to the Echinococcosis outpatient clinic at the University Hospital of Sassari (Sardinia, Italy) for a pain in the left flank.

Melanonychia describes black pigmentation of the nail plate that results from either melanocyte activation (such as infections, local inflammatory disorders, local trauma affecting the nail plate, numerous systemic conditions, and medications) or melanocyte hyperplasia (such as benign neoplasms or malignant tumors) or blood (resulting from a trauma-associated subungual hematoma). The black dyschromia may include not only the nail plate but also the proximal nailfold. The Hutchinson sign refers to black discoloration of both the proximal nailfold and adjacent nail plate when the underlying pigmented lesion is a malignant melanoma.
