Background: Risk of scar defect is inversely correlated with lower uterine segment thickness. The study aims to assess the diagnostic accuracy of sonographic measurement of the lower uterine segment thickness near term in predicting uterine scar defect in women with prior Caesarean section and ascertain the best cut-off value for predicting uterine rupture in our country. Methods: This observat...

Introduction: MRI-based quantification of the cartilage thickness is a robust and well validated technique for the assessment of cartilage degradation in osteoarthritis [1], and for the analysis of cartilage deformations after exercise [2]. Nowadays changes in cartilage thickness are evaluated by comparing averaged thickness over regions defined on an anatomical basis [1]. However, the combinat...

BACKGROUND/AIMS Although studies using optical coherence tomography (OCT) reported that the retinal nerve fibre layer (RNFL) thickness of myopic eyes was thinner than those of normal controls, it was unclear if this finding indicated the difference in actual structural thickness or that created by sources affecting accuracy of OCT measurement. This study's aim was to evaluate the effect of refr...

BACKGROUND The aim of this study was to measure the finished thickness of a single identical 4-mm EVA mouthguard model from a large fabricated sample group and to evaluate the degree of material thinning and variations during the fabrication process. MATERIALS AND METHODS Twenty boxes were distributed to dental technician participants, each containing five duplicated dental models (n = 100), ...

AIMS To report and compare the cap thickness predictability of small incision lenticule extraction (SMILE) and flap thickness of femtosecond laser-assisted in situ keratomileusis (femto-LASIK). SETTINGS AND DESIGN Beyoglu Eye Training and Research Hospital, Refractive Surgery Department, Istanbul, Turkey. Retrospective pilot study. MATERIALS AND METHODS Medical records of patients who had S...

BACKGROUND Ultrasonographic measurement of the plantar fascia can be used to objectively diagnose plantar fasciitis. The purpose of this study was to determine the long-term effectiveness of Extracorporeal Pulse Activated Therapy (EPAT) for the treatment of plantar fasciitis using ultrasonographic measurement as an objective outcome measure, with a minimum followup of 12 months. METHODS Patie...

PURPOSE To evaluate the accuracy of sonographic endometrial thickness and hysteroscopic characteristics in predicting malignancy in postmenopausal women undergoing surgical resection of endometrial polyps. METHODS Five hundred twenty-one (521) postmenopausal women undergoing hysteroscopic resection of endometrial polyps between January 1998 and December 2008 were studied. For each value of so...

This paper deals with an inspection of defects including corrosion and leakage by Acoustic Emission (AE) in an oil tank floor. In contrast to intrusive methods such as magnetic flux leakage, eddy current or ultrasonic, there is no need to emptying and entering the tank in AE method in order to inspection. In this research AE investigation and AE source location is presented in detail. The resul...

BACKGROUND AND PURPOSE The purpose of our study was to investigate the effect of section thickness on MR detection of brain lesion volume and measurement precision in patients with multiple sclerosis (MS). METHODS Eight subjects with known MS were studied on a 1.5-T MR system. We used a 3D fast fluid-attenuated inversion-recovery sequence to obtain contiguous axial brain images at section thi...

PURPOSE To evaluate the effects of various factors on the variability of retinal nerve fiber layer (RNFL) thickness measurements using the Stratus optical coherence tomography (OCT) in normal and glaucomatous eyes. METHODS Four hundred seventy-four subjects (103 normal eyes and 371 glaucomatous eyes) were scanned to determine the RNFL thickness measurements using the Stratus OCT. Measurements...
