Purpose: We aimed to determine the position and size of the sphenoid sinus (SS) in our study and compare the results of the measurements relative to age, gender, and the presence of pituitary adenoma using multidetector computerized tomography (MDCT).

Methods: We retrospectively evaluated the paranasal sinus computerized tomography (CT) images of 200 individuals (age range of all the individuals 4-84 years; 101 females, 99 males; age range of individuals with pituitary adenoma 15-63 years; 15 females, 9 males) with 24 pituitary adenomas. The shape of SS were identified and classified, volume were measured by MDCT also for individuals with pituitary adenoma.

Purpose: We aimed to research in detail the morphology of the facet orientation (FO) and tropism (FT) in degenerative diseases.

Method: This study consisted of patients with disc degeneration (DD) and with lumbar spondylolisthesis (LS) as well as a control group without these two diseases. The group of patients with DD was separated by DD grades.

Introduction: Radiologic evaluation is mandatory to assess the type of endoscopic approach concerning sinonasal pathology and reconstruction of fractured defects before any treatment modalities are instituted related to medial wall of the orbit.

Objective: The goal was to provide improved understanding of the lamina papyracea variations and the relationship with the orbital morphometry.

Methods: This retrospective study was performed using computed tomography scans of 200 orbits and results were compared with respect to age, sex, laterality and LP variations.

Introduction: The type of endoscopic approach chosen for vidian neurectomy can be specified by evaluating the vidian canal and the surrounding sphenoid sinus structures.

Objective: The variations and morphometry of the vidian canal were investigated, focusing on the functional correlations between them which are crucial anatomical landmarks for preoperative planning.

Methods: This study was performed using paranasal multidetector computed tomography images that were obtained with a section thickening of 0.

Background: Sphenoethmoid cells may be above the sphenoid sinus with/ or without con-tact to optical nerve. Although sphenoethmoid cells are theoretically considered to possibly influence the sphenoid sinus volume, we could not find any study in the literature on this issue.

Aims: The aim of our study was to detect sphenoethmoid cells and measure the sphenoid sinus vol-ume using multiplanar computerized tomography and also investigate the correlation between the presence of sphenoethmoid cells and the sphenoid sinus volume.

Introduction: The course of the infraorbital canal may leave the infraorbital nerve susceptible to injury during reconstructive and endoscopic surgery, particularly when surgically manipulating the roof of the maxillary sinus.

Objective: We investigated both the morphometry and variations of the infraorbital canal with the aim to show the relationship between them relative to endoscopic approaches.

Methods: This retrospective study was performed on paranasal multidetector computed tomography images of 200 patients.

Carpenter syndrome (Acrocephalopolysyndactyly type 2, OMIM 201000) is a rarely seen autosomal recessive disorder. In addition to abnormalities such as acrocephaly, craniosynostosis, facial asymmetry, polydactyly and syndactyly, obesity, hypogonadism, mental retardation, and corneal opacity, it may frequently be accompanied by congenital heart diseases such as ventricular septal defect, patent ductus arteriosus and pulmonary stenosis. Double outlet right ventricle is a defect in which both major arteries originate in the morphological right ventricle.

Hydatid cyst is an endemically seen parasitic disease and caused by the larval form of Echinococcus parasites. The disease is mostly seen in liver and lung, and the other involvement is rarely seen. Head and neck involvement is extremely rarely seen and its frequency in the literature is reported as less than 1%.

Purpose: Splenic artery embolization is a minimally invasive therapeutic procedure utilized in a number of disorders. Ankaferd blood stopper (ABS) is a novel hemostatic agent with a new mechanism of action independent of clotting factors. We aimed to investigate the safety and efficiency of ABS for splenic artery embolization in a sheep model.

Introduction: Onodi cells are the most posterior ethmoid air cells and extend superolateral to the sphenoid sinus. These cells are also intimately related with the sphenoid sinus, optic nerve, and carotid artery. Radiologic evaluation is mandatory to assess for anatomic variations before any treatment modalities related to the sphenoid sinus.

Background: The purpose of this study was to compare the left ventricular parameters obtained from multi-detector row computed tomography (MDCT) studies with two-dimensional echocardiography (2DE), and magnetic resonance imaging (MRI), which is accepted as the gold standard in the evaluation of left ventricular functions. The study also aimed to evaluate whether or not there is a relationship between the MR-Argus and CMR tools software programs which are used in post-process calculations of data obtained by MRI.

Material/methods: Forty patients with an average age of 51.

Two Gram-stain-positive, moderately thermophilic, endospore-forming, rod-shaped, motile bacteria designated PDF4 and PDF10, were isolated from Camkoy hot spring in the provinces of Aydın, Turkey and were characterized in order to determine their phylogenetic position. 16S rRNA gene sequence analysis revealed that the two strains belonged to the genus . Strain PDF4 showed highest 16S rRNA gene sequence similarity to strain PDF10 (99.

Purpose: We aimed to demonstrate the success and reliability of a novel puncture, aspiration, injection, and reaspiration (PAIR) technique in liver hydatid cysts.

Methods: Percutaneous treatment with ultrasonographic guidance was performed in 493 hepatic hydatid cysts in 374 patients. Patients were treated with a new PAIR technique by single puncture method using a 6F trocar catheter.

Background: Amyand's hernia is described as the presence of an appendix vermiformis in the inguinal hernia sac. The incidence of Amyand's hernia is approximately 1% of all inguinal hernias. Amyand's hernia is diagnosed intraoperatively or preoperatively with radiologic examinations.

Purpose: We studied the use of magnetic resonance imaging in the diagnosis of penile fracture.

Materials And Methods: Between 1997 and 2012, fifteen patients (age range 17-48 years, mean age 37 years) with suspected penile fracture underwent MRI examinations. Ten patients were injured during sexual intercourse, whereas four patients were traumatized by non-physiological bending of the penis during self manupilation, one patient was traumatized falling from the bed.

Basically malignant tumors in the retroperitoneal region arise from a heterogeneous group of tissues: mesodermal, neurogenic, germ cell, and lymphoid. Although rare, benign tumors and cystic masses can be also encountered in retroperitoneal space. Developments in computed tomography (CT) and magnetic resonance imaging (MRI) have contributed to both diagnosis and staging of the retroperitoneal tumors.
