Investigation of alterations in retrobulbar hemodynamics and their correlation with choroidal thickness after strabismus surgery.

Background: To evaluate the changes in retrobulbar circulation after strabismus surgery and to assess the relationship of these changes with choroidal thickness (CT).

Methods: This prospective study included 26 eyes of 26 patients who underwent strabismus surgery and 15 eyes of 15 healthy individuals as control group. The patients who had single horizontal muscle surgery were included in Group 1 (n = 14); and those who had surgery on both horizontal muscles were included in Group 2 (n = 12).

Corpus callosum thickness: A predictive factor for the first drug efficiency of self-limited epilepsy with centrotemporal spikes (selects)?

Objective: To investigate the existence of a possible linkage between the thickness of corpus callosum (CC) regions and the first antiepileptic drug response in patients with Selects.

Materials And Methods: CC thickness of 68 patients with Selects and 42 healthy controls between 4 and 12 years of age were measured using brain magnetic resonance imaging (MRI). Clinical and EEG features of newly diagnosed Selects patients were recorded.

Long Term Radiological and Clinical Outcome of Symptomatic Lumbar Intraspinal Synovial Cyst: A Retrospective 4-Year Study.

Aim: To examine the prevalence of symptomatic lumbar synovial facet cysts in lumbar spinal magnetic resonance imaging (MRI) of patients who admitted to neurosurgery clinic, retrospectively. Also, we aimed to report the clinic and radiologic outcome of patients with symptomatic spinal synovial cyst, who undergo conservative treatment.

Material And Methods: One thousand two hundred forty-three patients who admitted to Ordu University Neurosurgery outpatient clinic between 2015-2019 and underwent lumbosacral MRI and lumbosacral computed tomography examinations were reviewed retrospectively.

White Blood Count Can Be a Practical Guide for the Differential Diagnosis of Breast Abscess and Idiopathic Granulomatous Mastitis.

Introduction and aim Idiopathic granulomatous mastitis (IGM) is an inflammatory disease of the breast and has the same symptoms and radiologic imaging as breast abscess (BA). The aim of this study is to evaluate the use of inflammatory markers as white blood count (WBC), C-reactive protein (CRP), and neutrophil to lymphocyte ratio (NLR) as a potentially useful tool for the differential diagnosis of BA and IGM. Methods In this retrospective study, we analyzed 31 patients with IGM and 47 patients with BA between January 2013 and April 2020.

Retinal nerve fibre and ganglion cell inner plexiform layer analysis by optical coherence tomography in asymptomatic empty sella patients.

To investigate the clinical importance of the thicknesses of the retinal nerve fibre (RNFL) and ganglion cell and inner plexiform layer (GCL+) by spectral domain optic coherence tomography (SD-OCT) in asymptomatic empty sella (ES) patients. In this cross-sectional, non-randomized prospective study, 44 ES patients and 74 age- and sex-matched healthy individuals were evaluated. All the patients and controls competed an automated 30-2 visual field (VF) test.

The impact of intravitreal dexamethasone implant (Ozurdex®) on retrobulbar hemodynamics in patients with diabetic macular edema and retinal vein occlusions.

To evaluate the effect of single intravitreal dexamethasone implant (Ozurdex) on ocular blood flow velocities in patients with diabetic macular oedema (DME) and retinal vein occlusions (RVO). This prospective non-randomized interventional study included injected and fellow eyes of 12 patients with DME and of 16 patients with RVO treated with intravitreal Ozurdex. Colour Doppler Ultrasonography (CDU) measures of the central retinal artery (CRA), posterior ciliary artery (PCA), ophthalmic artery (OA) those are peak systolic velocity (PSV), end diastolic velocity (EDV), resistive index (RI) and pulsatility index (PI) were performed in both injected and uninjected eyes before injection, at one week, one month after injection, and prior to re-injection.

Effects of nodule characteristics on sampling number and duration of thyroid fine-needle aspiration biopsy: size does not matter, but cystic degeneration ratio does.

Background Ultrasound-guided fine needle aspiration biopsy (FNAB) of thyroid nodules, though the most accurate method to rule out malignancy, still has an inherent risk of yielding non-diagnostic specimens despite immediate assessment of specimen adequacy by an on-site cytopathologist. Purpose To evaluate the effects of nodule volume and extent of cystic degeneration on total biopsy time and number of aspirations required for obtaining an adequate specimen. Material and Methods A total of 510 patients underwent FNAB by a single radiologist accompanied by a cytopathologist who immediately assessed each sample for specimen adequacy.

Use of a Volume Navigation Technique for Combining Real-Time Ultrasound and Contrast-Enhanced MRI: Accuracy and Feasibility of a Novel Technique for Locating Breast Lesions.

Objective: The objective of this study was to evaluate the accuracy of the volume navigation technique for combining real-time ultrasound and contrast-enhanced MRI (CE-MRI) of breast lesions.

Subjects And Methods: Thirty-eight women with single breast lesions underwent 3-T MRI. A 3.

Utility of Interobserver Agreement Statistics in Establishing Radiology Resident Learning Curves During Self-directed Radiologic Anatomy Training.

Rationale And Objectives: The aim of the study was to ascertain the learning curves for the radiology residents when first introduced to an anatomic structure in magnetic resonance images (MRI) to which they have not been previously exposed to.

Materials And Methods: The iliolumbar ligament is a good marker for testing learning curves of radiology residents because the ligament is not part of a routine lumbar MRI reporting and has high variability in detection. Four radiologists, three residents without previous training and one mentor, studied standard axial T1- and T2-weighted images of routine lumbar MRI examinations.

Outcomes of unconventional utilization of BI-RADS category 3 assessment at opportunistic screening.

Background An important difficulty regarding the Breast Imaging Reporting and Data System (BI-RADS) category 3 assessment is the need for extensive diagnostic workup and an additional 6-month follow-up study. Purpose To evaluate the feasibility of the BI-RADS category 3 assessments at opportunistic screening. Material and Methods Mammography charts of 9062 screening patients in a major teaching hospital situated in an urban setting of a developing country were evaluated retrospectively (1997-2010).
