OBJECTIVE The aim of this study was to assess the clinical role of (18)F-FDG PET/CT for the evaluation of lymph node metastasis in periorbital malignancies, compared with CT alone. MATERIALS AND METHODS We analyzed eighteen PET/CT and CT scans in 15 patients with biopsy-proven periorbital malignancies. We compared the diagnostic capabilities of PET/CT and CT with regard to nodal metastasis by...

PURPOSE To characterize the appearance of the gasserian ganglion on contrast-enhanced MR images. METHODS We retrospectively reviewed the MR images from 57 patients with suspected pituitary disease. These patients had undergone unenhanced and contrast-enhanced MR imaging of the sella, including evaluation of Meckel's cave. None of the patients had clinical signs or symptoms referable to the fi...

BACKGROUND There has been renewed interest in the cochlear duct length (CDL) for preoperative cochlear implant electrode selection and postoperative generation of patient-specific frequency maps. The CDL can be estimated by measuring the A-value, which is defined as the length between the round window and the furthest point on the basal turn. Unfortunately, there is significant intra- and inter...

OBJECTIVES The nvCT has a 377 bp plasmid deletion that has caused commonly used nucleic acid amplification tests to generate false negative results. In Swedish counties nvCT has been reported to account for up to 65% of all chlamydia cases in 2007. The aim was to evaluate the CTQ DNA amplification assay for detection of the new Chlamydia trachomatis variant (nvCT) in urine specimens from a labo...

Raw data from small punch tensile/fracture tests at two displacement rates in the temperature range from -196 °C to room temperature on Grade 91 ferritic/martensitic steel are presented. A number of specimens were analyzed after testing by means of X-ray computed tomography (CT). Based on the CT volume data detailed 3D surface maps of the specimens were established. All data are open access and...

One hundred and twenty four cases of Reye’s syndrome admitted to Vani Vilas Children Hopital, bangalore were investigated. Clinical, biochemical and epidemiological details were obtained. The median age was five years, with no difference in sex ratio. This disease was frequent in winter months. Cases clustered in certain congested localities of the city among lower socio econnomic strata. Aspir...

An 81-year-old man was referred to our hospital with bilateral multiple patchy opacities on chest radiography. His chief complaints were a few months' history of intermittent mild cough and slightly yellow sputum. Chest computed tomography (CT) showed non-segmental air-space consolidations with ground-glass opacities. Amyloid deposition with organizing pneumonia (OP) was seen in transbronchial ...

Background: This study evaluated the performance of the BD ProbeTec Chlamydia trachomatis Q (CTQ) Amplified DNA Assay on the BD Viper System with XTR Technology in a multicenter study. Methods: Specimens were collected at 7 geographically diverse clinical sites from 1538 women and men attending sexually transmitted disease, family planning, and obstetrics and gynecology clinics. There were 1465...

PURPOSE To define the anatomy of the facial and vestibulocochlear nerves in the internal auditory canal on parasagittal CT scans of cadaveric specimens and to compare this anatomy with findings on in vivo T2-weighted two-dimensional fast spin-echo and three-dimensional turbo spin-echo MR images. METHODS Thirty-eight formalin-fixed cadaveric temporal bones were examined with 1-mm-thick contigu...

SRI International has investigated the feasibility of measuring representative toughness values for nuclear pressure vessel materials using small cracked round bars (CRBs). We tested a weldment material [Heavy-Section Steel Irradiation (HSSI) Weld 72W with 0.23% copper] at six temperatures (-150%, -800, -500, 00, 230, and 50'C) using CRBs and compared the fracture-toughness results with data ob...
