The determination of the radiation exposure history population has become increasingly important in study effects low-level radiation. present work was started to try obtain an vivo dosimeter that could give indication exposure. Dental enamel is only living tissue which retains indefinitely its history, and electron spin resonance measurements have shown signal can be resolved down about 10 cGy. Measurements on samples from general estimates are reasonable, one measurement a patient who had...
To determine if quantitative and qualitative shear wave elastography have roles in evaluating musculoskeletal masses.105 consecutive patients, prospectively referred for biopsy within a specialist sarcoma centre, underwent B-mode, (m/s) (colour map) elastography. Reference was histology from subsequent or excision where possible. Statistical modelling performed to test data and/or B-mode imaging predicting malignancy.Of 105 masses, 39 were malignant 6 had no but benign characteristics at 12...
Abstract Objective To evaluate if imaging findings and shear wave elastography (SWE) can differentiate between lipoma low-to-intermediate grade liposarcoma to assess for SWE reproducibility across different manufacturer machines. Materials methods Consecutive patients referred lipomatous soft tissue mass biopsy prospectively underwent B-mode ultrasound (US), on two machines (LOGIQ-E9 SSI-Aixplorer), MRI. Three musculoskeletal radiologists independently scored images gave an assessment of...
Objectives To evaluate quantitative sonoelastography of benign and malignant musculoskeletal soft tissue masses. Methods We conducted a prospective study 50 patients from specialist sarcoma center who had extremity masses referred for biopsy. After consent, the shear wave velocity (meters per second) was measured in longitudinal transverse planes (3 readings each plane mean calculated). All subsequently underwent biopsy, excision, or both, with histologic diagnosis taken as reference...
Abstract The determination of the radiation exposure history population has become increasingly important in study effects low level radiation. Dental enamel is only living tissue which retains indefinitely its history, and electron spin resonance measurements have shown that signal can be resolved down to about 0.1 Gy. Measurements on samples from general give estimates are reasonable, one measurement a patient who had radiotherapy mouth area showed good correlation with tumour dose. Recent...
To assess whether a single isotropic three-dimensional (3D) fast spin echo (FSE) proton density fat-saturated (PD FS) sequence reconstructed in three planes could replace the PD (FS) sequences our standard protocol at 1.5 T (Siemens Avanto, Erlangen, Germany).A 3D FSE water excitation was included for 95 consecutive patients referred routine knee MRI. This used to produce offline reconstructions axial, sagittal and coronal planes. Two radiologists independently assessed each case twice, once...
AbstractThe EPR signals in dental enamel produced by radiation and heat were studied. The inherent background signal at g = 2·005, a radiation-produced 2·002 have different saturation behaviour with microwave power, this affords method of optimization. Heating temperatures from 100°C to 450°C produces range radical species which been characterized their g-values, line widths behaviour. Standard drilling radicals appear be similar those heat.
Lipomas and lipoma variants are common soft tissue tumours but not commonly found in the oral maxillofacial region. We report a case of classic located on medial aspect mandibular ramus, within bone, first seen by an surgeon during treatment planning for routine extractions. Initial panoramic radiography indicated expansive tumour area foramen proximal end canal, apparently body mandible. Subsequent imaging with CT revealed well-circumscribed left bone itself. Histological analysis operative...
Abstract Soft tissue lesions are a wide range of tumors mesenchymal cell origin, occurring anywhere in the body with vast number histological subtypes both benign and malignant. These common clinical practice majority benign. This article focuses on soft sarcoma trunk extremities discusses their imaging guidelines.
Abstract Introduction The os intermetatarseum is an uncommon accessory ossicle of the foot located dorsally, between bases first and second metatarsals that are usually asymptomatic. In setting trauma, this can clinically mimic a Lisfranc fracture–dislocation, potentially disabling condition often requiring surgical intervention. Methods study, 47 cases were reviewed across several Western Australian (WA) Hospitals characterised based on morphology. Any fractures recorded, their reviewed....
For radiotherapy, an error in the complicated treatment planning or procedure is a possibility, however remote. Thus, present study electron spin resonance (ESR) dental enamel was investigated for first time as means of retrospective dosimetry validating applied radiotherapy doses to head and neck regions. Total absorbed radiation measured by ESR were compared determined 19 patients who received intra-oral, pharyngeal laryngeal malignancies, total-body irradiation prior bone marrow...
Purpose: We have found that 3-tesla magnetic resonance imaging (3TMRI) is as clinically effective (MR) arthrogram when it comes to investigating patients with femoroacetabular impingement (FAI). It also a noninvasive procedure can be done more efficiently, equivalent radiological and surgical outcomes. would recommend 3TMRI the primary investigation for presenting FAI-type symptoms. Methods: This was retrospective review of single surgeon series 59 operative cases, over 3 years. The...
