Objective: To investigate the aetiology of Stafne's bone defects by analysing CT findings two types defects, which appeared differently on panoramic radiographs. Methods: 32 lesions with suspicion defect a radiograph were categorised into groups: typical "Stafne type", showed connection to base mandible, and non-typical "Cyst no connection. Age, sex, existence hypertension following findings: location, size inner content defect, expansion buccal cortical bone, location submandibular glands,...
We evaluated the diagnostic performance of a deep learning system for detection Sjögren's syndrome (SjS) in ultrasonography (US) images, and compared it with inexperienced radiologists.100 patients confirmed diagnosis SjS according to both Japanese criteria American-European Consensus Group 100 non-SjS that had dry mouth suspected but were definitively diagnosed as enrolled this study. All underwent US scans parotid glands (PG) submandibular (SMG). The training group consisted 80 patients,...
Purpose: To evaluate the usefulness of combination two non-invasive modalities US and MR imaging to diagnose masses in parotid region. Material Methods: The findings 21 patients with were analyzed retrospectively by radiologists without any clinical or histopathological information. specific points evaluated location, shape, margin, internal architecture, intensity level on both MR, posterior echo enhancement US, capsule-like lining tumor MR. Results: concerning shape margin fairly good...
The purpose of this study was to clarify the effects exposure parameters and image-processing methods when using CBCT detect clear unclear mandibular canals (MCs).24 dry half mandibles were divided into 2 groups with MCs based on a previous study. Mandibles scanned system varying (tube voltages 60 kV, 70 kV 90 kV; tube currents mA, 5 10 mA 15 mA) obtain total 144 scans. images processed different slice thicknesses ImageJ software (National Institutes Health, Bethesda, MD). Five radiologists...
IgG4-related dacryoadenitis and sialoadenitis (IgG4-DS), so-called Mikulicz's disease, is characterized by elevated serum IgG4 infiltration of IgG4-positive plasma cells in glandular tissues. Recently, several studies reported both malignant lymphoma developed on the background IgG4-associated conditions IgG4-producing (non-IgG4-related disease).We report case a 70-year-old man who was strongly suspected IgG4-DS because high concentration (215 mg/dl) bilateral swelling parotid submandibular...
Mantle cell lymphoma (MCL) is a relatively uncommon type of non-Hodgkin lymphoma. It develops in the outer edge lymph node called mantle zone. In contrast, IgG4-related dacryoadenitis and sialoadenitis (IgG4-DS) characterized by elevated serum IgG4 persistent bilateral enlargement lacrimal glands (LGs) salivary (SGs), with infiltration IgG4-positive plasma cells. Recent studies indicated importance differentiation between IgG4-DS malignant lymphoma.An 82-year-old man was suspected because...
Kimura disease (KD) is a rare, chronic inflammatory disorder characterized by subcutaneous granuloma in the head and neck region, as well increased eosinophil counts high serum immunoglobulin E (IgE) levels. suspected to be an IgE-mediated disease, associated with allergic response, which antigen-specific B cells are stimulated undergo specific IgE class switching disease-specific CD4+ T (Th) help. Thus, exploration of Th affected tissues KD highly promising field investigation. However,...
To elucidate the effect of automatic exposure compensation (AEC) on diagnostic accuracy proximal caries by comparing several digital intraoral imaging systems with a film.Twenty-seven extracted teeth served as samples. Three radiographic systems; Compuray, Dixel, and Sens-A-Ray without scintillator layer, Kodak Ekta-speed Plus films were used recording media. Radiographs samples obtained each medium under seven to eight different exposures including optimum level. Six oral radiologists...
