The Role Of Lateralisation And Sex On Insular Cortex: 3d Volumetric Analysis, Fatma Öz, Ni̇yazi̇ Acer, Ni̇han Katayifçi, Güneş Aytaç, Kami̇l Karaali̇, Muzaffer Si̇ndel

Turkish Journal of Medical Sciences

Background/aim: The insula has attracted the attention of many neuroimaging studies because of its key role between brain structures. However, the number of studies investigating the effect of sex and laterality on insular volume is insufficient. The aim of this study was to investigate the differences in insular volume between sexes and hemispheres. Materials and methods: A total of 47 healthy participants [24 males (20.08 ± 1.44 years) and 23 females (19.57 ± 0.90 years)] underwent magnetic resonance imaging (MRI). Imaging was performed using the 3T MRI scanner. The insular volume was measured using the Individual Brain Atlases using Statistical …

Fully Automated Morphological Analysis Of Patients With Obstructive Sleep Apnea, Oktay Alğin, Burak Akin, Gökhan Ocakoğlu, Evri̇m Özmen

Turkish Journal of Medical Sciences

Background/aim: Obstructive sleep apnea syndrome (OSAS) is a disease characterized by episodic hypoxia. We aimed to use the Freesurfer program for global evaluation of morphological changes in OSAS patients. Materials and methods: Three-dimensional T1-weighted images were obtained, and intracranial morphology was assessed in 18 patients with OSAS and 20 controls. Results of the volume and the cortical thickness analyses of both groups were compared statistically. Results: The total cortical, left-right hemispheres gray matter (GM), corpus callosum, and total GM volumes were lower in OSAS patients when compared with the control group (P < 0.001). The average cortical thickness was lower in OSAS patients bilaterally in pars orbitalis, paracentral, rostral middle frontal, middle frontal, orbital, and superior frontal gyri when compared with the control group (P < 0.05). Furthermore, the volume and average cortical thickness of multiple anatomic regions, apart from the brain parts mentioned above, were decreased unilaterally (e.g., hippocampus, cingulum, putamen, thalamus) in OSAS patients (P < 0.05). Conclusion: Multiple morphologic changes occur in the cerebral structures of OSAS patients due to intermittent ischemia episodes. Detection of those areas with Freesurfer is easier. New studies with large series would be needed for these subjects.


Urothelial Cancers: Clinical And Imaging Evaluation, Hali̇l Arslan, Fati̇h Mehmet Tezcan, Oktay Alğin Jan 2012

Urothelial Cancers: Clinical And Imaging Evaluation, Hali̇l Arslan, Fati̇h Mehmet Tezcan, Oktay Alğin

Turkish Journal of Medical Sciences

Urothelial cancers are currently diagnosed more commonly parallel to the recent developments in imaging techniques. Early diagnosis of these tumors, together with better treatment options, decreases the morbidity and the mortality significantly. This review aims to summarize the imaging findings of urothelial tumors, both at the pretreatment and posttreatment follow-up stage.


Evaluation Of Radiological Findings In 160 Adult Patients With Tuberculous Meningitis, Kadri̇ye Yaşar, Fi̇li̇z Pehli̇vanoğlu, Ahmet Şengöz, Gönül Şengöz Jan 2012

Evaluation Of Radiological Findings In 160 Adult Patients With Tuberculous Meningitis, Kadri̇ye Yaşar, Fi̇li̇z Pehli̇vanoğlu, Ahmet Şengöz, Gönül Şengöz

Turkish Journal of Medical Sciences

To evaluate the radiological findings of 160 adult patients with tuberculous meningitis (TBM). Materials and methods: Using a standard data collection form, 160 patients with TBM who had been followed for 11 years were assessed retrospectively. Cranial imaging results were obtained by computed tomography (CT) and magnetic resonance imaging (MRI), and pulmonary findings were obtained by chest X-ray and CT. Tuberculomas were assessed with a nominal tuberculoma classification index (TCI) scale. Results: Of the 160 patients, 80 were males and the mean age was 32.18 ± 13.62 years (range: 14-78). On admission, 84% were in stages II or III; 27 …


Clinical Features, Eeg Findings And Outcome In Patients With Bilateral Periventricular Nodular Heterotopia And Epilepsy, Aysun Ünal, Serap Saygi Jan 2007

Clinical Features, Eeg Findings And Outcome In Patients With Bilateral Periventricular Nodular Heterotopia And Epilepsy, Aysun Ünal, Serap Saygi

Turkish Journal of Medical Sciences

Aim: To review the clinical, electrophysiological and neuroimaging data of eight adult patients (4F/4M) with epilepsy and bilateral periventricular nodular heterotopia (PNH) after a long duration of follow-up. Materials and Methods: The clinical charts were reviewed for demographic and clinical features, seizure types and frequency, treatment and prognosis of all eight patients who were under follow-up by one of the authors (SS). The recordings of video-EEG monitoring with scalp electrodes in five patients and routine EEGs in all patients were reviewed. Results: The clinical semiology was in accord with seizures originating from temporal lobe region in four patients, while an …

Turkish Journal of Medical Sciences

The sulcus angle of the femoral trochlea is particularly important for evaluating the patellofemoral joint. Our experimental study aimed to assess the osseous femoral sulcus angle radiologically in the right and left knees and osteologically in the right and left femurs in males and females. The osseous sulcus angle of 28 male right, 22 male left, 21 female right and 29 female left knees was measured on magnetic resonance images (MRIs) and by a goniometer; the angle was measured in 40 right and 40 left femurs. In MRIs, the mean sulcus angle in males and in females was 134° ± …
