Item Breast Involvement by Hematologic Malignancies: Ultrasound and Elastography Findings with Clinical Outcomes(2017) Aslan, Hulya; Pourbagher, Aysin; 0000-0002-7138-246X; 29296470; AAK-9104-2021Objective: Hematological malignancies very rarely involve the breast. The aim of this study is to retrospectively evaluate B-mode ultrasound (US) and elastography (ES) findings of breast involvement by hematologic malignancies with clinical outcomes. Materials and Methods: All core-needle biopsy results that were performed at our tertiary breast center from January 2013 to September 2016 were searched. Our search revealed 9 patients with breast involvement either by leukemia or lymphoma. All patients were examined using B-mode US and ES. US and ES findings were analyzed with the consensus of two radiologists, and clinical outcomes were noted. Results: The mean age of the study population was 41.6 years (range, 20-83 years). Two patients showed diffuse hypoechoic parenchymal infiltration. The elasticity assessments of these lesions were soft and intermediate. The remaining 7 patients had mass lesions. The elasticity assessment of these masses according to Breast Imaging Reporting and Data System US was as follows: Soft (n = 1), intermediate (n = 4), high (n = 2). Conclusions: It is important to consider that hematologic malignancies may appear as soft or intermediate lesions on ES. Patients' history and clinical background should help us to consider breast involvement. In addition, the clinical outcomes may not be related with elasticity assessments.Item Diagnostic value of acustic radiation force impulse imaging in the assessment of salivary gland involvement in primary Sjogren's sydrome(2018) Haberal, Kemal Murat; Turnaoglu, Hale; Rahatli, Feride Kural; Uslu, Nihal; Pamukcu, Melih; 0000-0002-8211-4065; 0000-0002-0781-0036; 30167584; R-9398-2019Aims: The aim of this study is to investigate the diagnostic value of Acoustic Radiation Force Impulse (ARFI) imaging in the assessment of salivary gland involvement in primary Sjogren's syndrome (pSS). Material and methods: Twenty five patients with pSS and 25 healthy volunteers were included. First, echostructures and the thickness of the submandibular and parotid glands were evaluated by B-mode ultrasonography. Then, ARFI imaging with Virtual Touch Quantification (R) was performed. Ten independent shear wave velocity measurements were taken from each gland. Finally, the mean shear wave velocity (SWV) values were calculated, and used for further analysis. Results: The mean SWV values of parotid and submandibular glands were significantly higher in the pSS patients than in the healthy control group (p < 0.001). The cut-off of SWV values were calculated to be 1.98 m/s for submandibular glands, and 1.93 m/s for parotid glands. In pSS patients, the mean SWV values of parotid glands were higher than those of the submandibular glands (p < 0.001) and no statistically significant relationships between symptom duration or the degree of xerostomia and mean SWV values of parotid and submandibular glands were found (all p > 0.005). Conclusions: Our findings indicate that ARFI imaging may provide a non-invasive, simple and fast means of assessment of glandular impairment as an alternative test when other salivary gland tests are inconclusive or cannot be performed. ARFI may be a valuable adjunct for the clinical diagnosis of pSS.
