Electrical impedance tomography (EIT), a non-invasive technique used to image the electrical conductivity and permittivity within a body from measurements taken on the body's surface, could be used as an indicator for breast cancer. Because of the low spatial resolution of EIT, combining it with other modalities may enhance its utility. X-ray mammography, the standard screening technique for br...

OBJECTIVE The aims of this study were to establish parameters in panoramic radiography for interpretation of unilocular radiolucent lesions, and to compare the accuracy of diagnoses given by examiners before and after using these parameters. MATERIAL AND METHODS In Part I, 12 specialists analyzed 24 images and the diagnostic criteria used by each examiner to make correct diagnoses were used t...

PURPOSE To evaluate the application of the maxillofacial miniplate 1.5 in the repair of unilateral mandibular osteotomies in cats. METHODS Twelve adult cats were divided into two groups. In group 1 (n=6), the osteotomy was performed in the body of the mandible, behind the 1(st) molar. In group 2 (n=6), the osteotomy was performed between the 4(th) premolar and 1(st) molar. The osteotomy was f...

Abstract Background We investigated the mid-term clinical and radiological results of total hip arthroplasty (THA) using a three-dimensional (3D) porous titanium cup analyzed micromotion at interface subject-specific finite element (FE) analysis. Methods evaluated 73 hips 65 patients (6 men 59 women; mean age time surgery, 62.2 years; range, 45–86 years) who had undergone THA 3D cup. Clinical e...

AIM The aim of this study was to determine tumor necrosis factor-alpha (TNF-alpha) levels in periapical exudates and to evaluate their relationship with radiological findings. METHODOLOGY Periapical exudates were collected from root canals of 60 single-rooted teeth using absorbent paper points. TNF-alpha levels were determined by enzyme-linked immunosorbent assays. The samples were divided in...

Purpose To evaluate clinical and radiological outcome of the full cementation technique in revision total knee arthroplasty (TKA) using a constrained condylar knee (CCK) prosthesis. Materials and Methods Between January 2008 and March 2012, 18 cases (16 patients) of fully cemented revision TKA were performed using a CCK prosthesis. Fifteen cases of aseptic loosening (13 patients) and 3 cases ...

Cone beam computed tomography is a useful technique for imaging the craniofacial lesions. It produces more realistic images that facilitate interpretation. Juvenile ossifying fibroma (JOF) is a rare and benign fibro-osseous neoplasm that arises within the craniofacial bones, especially in the maxilla. Mandibular lesions can be seen in 10% of the cases.In both jaws, it has a predilection for the...

Intraoperative nephroscopy is a valuable and practical adjunct to renal surgery. A simplified methodology is described using familiar cystoscopic equipment and techniques. Its particular usefulness in the definition of small radiolucent defects of the renal collecting system is illustrated.

The technique of repairing defects of the skull with titanium is described. The skull contour can be accurately reproduced. The technique is simpler than wiring or suturing methods. The material is inert, radiolucent, and rigid.

PURPOSE To investigate the MR appearance of ossification of the posterior longitudinal ligament (OPLL) of the cervical spine. MATERIALS AND METHODS A retrospective review of MR images and conventional tomograms in 147 patients. RESULTS In the sagittal plane, proton-density images identified the ossified lesions more clearly than did T1- and T2-weighted images. All axial sequences identified...
