BACKGROUND Different target-filter combinations in computed radiography have different impacts on the dose and image quality in digital radiography. This study aims to evaluate the mean glandular dose (MGD) and modulation transfer function (MTF) of various target-filter combinations by investigating the signal intensities of X-ray beams. METHODS General Electric (GE) Senographe DMR Plus mammo...
OBJECTIVE To clarify the importance of squamous and glandular atypia in the genital tracts of women undergoing high-dose chemotherapy and receiving tamoxifen. STUDY DESIGN The pathology records of 769 female bone marrow transplant recipients from a five-year period at Duke University Medical Center were reviewed. One hundred fifteen cervicovaginal smears from 78 patients were available for ev...
Breast cancer treatments cause breast changes that are detectable in subsequent mammography exams. This work investigates if these perceived as differences composition by automatic exposure systems, and such high enough to have impact exam doses. Data was obtained for 226 patients treated with unilateral conservative surgery followed radiotherapy (S&RT) of the left (114) or right (112) breast, ...
Background: Minor salivary gland biopsy (MSGB) has been increasingly recognized as an important tool for the stratification of patients with primary Sjögren’s syndrome (pSS). Recently, presence follicular dendritic cell (FDC) networks in inflammatory infiltrate associated more severe biological and serological abnormalities compared less organized infiltrates. Objectives: To investigate associa...
After cervical sympathetic nerve stimulation, the rat submandibular gland releases a significant amount of kallikrein into the circulation. To determine whether this glandular kallikrein has kininogenase activity (kinin-generating capabilities) in the peripheral circulation and whether it plays a role in blood pressure regulation, we studied the effect of captopril on blood pressure in 48 hour-...
Purpose: To determine the number of extra images (EI) that are necessary for imaging large breasts when using a detector smaller than 24 cm×30 cm and to calculate the additional average glandular dose (AGD) for these images. Materials and Methods: The screening mammograms taken between 2007 and 2011 were assessed for a photon counting full-field digital mammography (PCM) system (detector size: ...
OBJECTIVE Recent studies have associated lower urinary tract symptoms (LUTS) in men with prostatic fibrosis, but a definitive link between collagen deposition and LUTS has yet to be demonstrated. The objective of this study was to evaluate ECM and collagen content within normal glandular prostate tissue and glandular BPH, and to evaluate the association of clinical parameters of LUTS with colla...
