    Abstract The purpose of this article is to report on 23 women with evidence of axillary adenopathy at breast imaging after recent COVID-19 vaccination. A total of 13% of patients had symptoms (axillary lump), 43% were undergoing screening, and 43% were undergoing diagnostic imaging for other reasons. BI-RADS category 2 was assigned in one case, BI-RADS 3 in 21 (ultrasound in 4-24 weeks), and BI-RADS 4 in one. Radiologist familiarity and evidence-based guidelines are needed to avoid follow-up imaging and biopsies for reactive adenopathy after COVID-19 vaccination.

    Abstract Statement of the Problem: Alveolar bone resorption associated with periodontal disease is a common finding and generally irreversible. It impairs mastication and causes esthetic problems for patients. Bisphosphonates are the most commonly used antiresorptive agents for bone diseases. Purpose: Considering the risk of bisphosphonate-related osteonecrosis of the jaw, this study aimed to assess the effect of 2% risedronate gel on calvarial bone defects in rabbits. Materials and Method: In this animal study, critical-size defects of 8mm were created in the calvaria of 20 New Zealand white rabbits. In group 1 (n=10), 2% risedronate gel was applied into the right side defect while the left side defect remained empty and served as control. In group 2 (n=10), placebo gel was applied into the right side defect, while the left side defect remained empty and served as control. Five rabbits in each group were sacrificed at 1month and the remaining five at 2 month, post-operatively, and tissue samples were collected for histomorphometric analysis. Histomorphometric assessments included bone fill, degree of inflammation, number of osteoblasts, number of osteoclasts, and foreign body reaction at the site. Data were statistically analysed using SPSS version 25 via the Dunn test and Kruskal-Wallis test. Results: No bone remodeling was noted in any group at 1 month. The risedronate group showed significantly higher bone fill than the other groups after 2 months (p= 0.016). At 2 months, the number of osteoblasts was significantly higher in the risedronate group (p< 0.05). The groups were not significantly different in terms of inflammation score at 1 (p= 0.31) or 2 (p=0.69) months. Foreign body reaction was not observed in any group at any time point. No osteoclast was detected in any group at any time point. Conclusion: Risedronate gel showed superior efficacy with regard to regeneration of rabbit calvarial bone defects compared to the placebo and control groups.

    Abstract Superficial angiomyxoma (SA) is a rare benign soft-tissue tumor, arising sporadically or as the earliest manifestation of Carney's complex. When it arises sporadically, the breast is infrequently involved with only few cases reported in the literature. Key imaging findings include T2 signal hyperintensity on MRI and hypervascularity. In this study, we report the clinical, radiological, surgical, and histopathologic findings of a case of sporadic SA of the breast in a 16-year-old girl.

    Abstract Background: Background parenchymal enhancement (BPE) is an established breast cancer risk factor. However, the relationship between BPE levels and breast cancer risk stratification remains unclear.
    Purpose: To evaluate the clinical relationship between BPE levels and breast cancer risk with covariate adjustments for age, ethnicity, and hormonal status.
    Study type: Retrospective.
    Population: 954 screening breast MRI datasets representing 721 women divided into four cohorts: women with pathogenic germline breast cancer (BRCA) mutations (Group 1, N = 211), women with non-BRCA germline mutations (Group 2, N = 60), women without high-risk germline mutations but with a lifetime breast cancer risk of ≥20% using the Tyrer-Cuzick model (Group 3, N = 362), and women with <20% lifetime risk (Group 4, N = 88).
    Field strength/sequence: 3 T/axial non-fat-saturated T1, short tau inversion recovery, fat-saturated pre-contrast, and post-contrast T1-weighted images.
    Assessment: Data on age, body mass index, ethnicity, menopausal status, genetic predisposition, and hormonal therapy use were collected. BPE levels were evaluated by two breast fellowship-trained radiologists independently in accordance with BI-RADS, with a third breast fellowship-trained radiologist resolving any discordance.
    Statistical tests: Propensity score matching (PSM) was utilized to adjust covariates, including age, ethnicity, menopausal status, hormonal treatments, and prior bilateral oophorectomy. The Mann-Whitney U test, chi-squared test, and univariate and multiple logistic regression analysis were performed, with an odds ratio (OR) and corresponding 95% confidence interval. Weighted Kappa statistic was used to assess inter-reader variation. A P value <0.05 indicated a significant result.
    Results: In the assessment of BPE, there was substantial agreement between the two interpreting radiologists (κ = 0.74). Patient demographics were not significantly different between patient groups after PSM. The BPE of Group 1 was significantly lower than that of Group 4 and Group 3 among premenopausal women. In estimating the BPE level, the OR of gene mutations was 0.35.
    Data conclusion: Adjusting for potential confounders, the BPE level of premenopausal women with BRCA mutations was significantly lower than that of non-high-risk women.
    Level of evidence: 3 TECHNICAL EFFICACY: Stage 3.

    Abstract In this day of rapidly advancing quantitative and molecular imaging techniques, imaging of veins and venous pathology still primarily relies on qualitative interpretation of ultrasound and venographic images. This article is primarily dedicated to understanding the nuances of the qualitative use of these two, by now, "old-fashioned" modalities. As such, the article is an attempt to help the imaging practitioner, in their daily practice, to avoid some of the interpretive mishaps that can befall the unwary. There are special strengths of the 3-dimensional imaging techniques of magnetic resonance imaging and computed tomography venography that will be briefly mentioned and discussed as to when and where they should be added to the venous imaging armamentarium.

    Abstract Salivary mucocele is a common lesion derived from minor salivary glands with various surgical or non-surgical treatment modalities. To evaluate the effect of a highly potent corticosteroid (dexamethasone) in the management of salivary mucocele, we performed intralesional injection of dexamethasone in nine patients with labial mucocele. Complete healing of lesions observed in seven of nine patients, and size reduction in two of them. No local scarring or deformity of the lower lip occurred in any of the patients. One patient reported local discomfort at the site of injection. Intralesional injection of dexamethasone is a potentially curative method in the treatment of mucocele.

    Abstract Objectives The purpose of this study was to validate T2* mapping as an objective, noninvasive method for the prediction of acetabular cartilage damage. Methods This is the second step in the validation of T2*. In a previous study, we established a quantitative predictive model for identifying and grading acetabular cartilage damage. In this study, the model was applied to a second cohort of 27 consecutive hips to validate the model. A clinical 3.0-T imaging protocol with T2* mapping was used. Acetabular regions of interest (ROI) were identified on magnetic resonance and graded using the previously established model. Each ROI was then graded in a blinded fashion by arthroscopy. Accurate surgical location of ROIs was facilitated with a 2-dimensional map projection of the acetabulum. A total of 459 ROIs were studied. Results When T2* mapping and arthroscopic assessment were compared, 82% of ROIs were within 1 Beck group (of a total 6 possible) and 32% of ROIs were classified identically. Disease prediction based on receiver operating characteristic curve analysis demonstrated a sensitivity of 0.713 and a specificity of 0.804. Model stability evaluation required no significant changes to the predictive model produced in the initial study. Conclusions These results validate that T2* mapping provides statistically comparable information regarding acetabular cartilage when compared to arthroscopy. In contrast to arthroscopy, T2* mapping is quantitative, noninvasive, and can be used in follow-up. Unlike research quantitative magnetic resonance protocols, T2* takes little time and does not require a contrast agent. This may facilitate its use in the clinical sphere.
