The purpose of our study was to determine the diagnostic role of diffusion-weighted imaging (DWI) in the differentiating of malignant and benign thyroid nodules by using fine needle aspiration biopsy cytology criteria as a reference standard. The apparent diffusion coefficient (ADC) values of the normal-looking thyroid parenchyma were also evaluated both in(More)
OBJECTIVE This study proposed to evaluate the value of diffusion-weighted MRI (DWI) to detect active inflammatory changes in the sacroiliac joints of patients with early axial spondyloarthritis (also spelled spondylarthritis). SUBJECTS AND METHODS Forty-two patients with chronic low back pain underwent clinical and MRI evaluation for axial(More)
OBJECTIVE The aim of this retrospective study was to report the clinical features and MR imaging findings of patients with brucellar spondylodiscitis. MATERIALS AND METHODS Twenty-two patients with spondylodiscitis, recruited among 152 patients with brucellosis referred from the Department of Infectious Diseases. Patients were diagnosed based on positive(More)
OBJECTIVE Reflux is an important criterion for the diagnosis of varicoceles and in the existence of reflux more than 1 s is the lower limit for the diagnosis of varicoceles. We proposed to assess the relationship of vein diameters with the incidence, duration and flow volume of reflux using color Doppler sonography (CDS) in patients with clinically(More)
PURPOSE Absence of the cavum septum pellucidum (CSP), the cisterna magna (CM), or both, and enlargement of either or both structures are associated with various central nervous system malformations. In an effort to determine normal sizes and relationships between these cranial structures, we measured the CSP and CM in normal fetuses in the second and third(More)
Detection of preradiographic sacroiliitis is important for early diagnosis of ankylosing spondylitis (AS) and related spondyloarthropathies. Magnetic resonance imaging (MRI) is a valuable tool for the diagnosis of sacroiliitis in the early and active stages. The aim of this study is to assess the value of pain provocation tests in detecting early active(More)
OBJECTIVES The aim of this study was to determine the role of semiquantitative strain elastography for differentiation of benign and malignant solid renal masses. METHODS Seventy-one patients with solid renal masses were prospectively examined with ultrasound elastography after grayscale sonography. Strain elastography was used to compare the stiffness of(More)
PURPOSE The aim of this study was to examine metabolite changes in different parts of the corpus callosum (CC), and to relate these changes to different age groups using magnetic resonance spectroscopy (MRS). MATERIALS AND METHODS A total of 76 healthy subjects participated in the study with MRS analyses (39 females and 37 males). Subjects were grouped by(More)
OBJECT aim of this study was to analyse the observer variability in the diagnosis and definition of disc pathologies with low and high-field strength MR scanners. MATERIAL AND METHODS 95 patients with low back pain or radicular pain who were referred from two different centers were included in the study. Fifty-seven patients were scanned with 0.3 T MR(More)
