Computed tomography analysis of the infraorbital canal and adjacent anatomical structures.

This study aimed to investigate the incidence of infraorbital canal (IOC) protrusion into the maxillary sinus via computed tomography (CT) and classify its variations. Additionally, it sought to identify nearby sinonasal variations that might elevate the risk of iatrogenic injury. Paranasal sinus CT of 500 patients was evaluated retrospectively.

Frequency and Clinical Significance of Incidental Findings Detected in Internal Acoustic Canal Magnetic Resonance Imaging of Patients with Audiovestibular Symptoms.

Objectives: Retrocochlear pathology associated with audiovestibular symptoms is detected in very few of the patients, and most of the internal acoustic canal magnetic resonance imaging examinations (IAC-MRIs) are either completely normal or include accompanying incidental findings (IFs). The aim of our study is to reveal the presence and frequency of IFs in IAC-MRIs, together with retrocochlear lesions. In addition, we intend to emphasize the clinical importance of these IFs.

Evaluation of the Hospitalized Coronavirus Disease 2019 Patients in First 3 Months of the Pandemic.

Objective: Data about Turkish coronavirus disease 2019 patients are limited. We evaluated hospitalized coronavirus disease 2019 patients who were followed up in the first 3 months of the pandemic.

Material And Methods: This retrospective, single-center, observational study included 415 confirmed hospitalized coronavirus disease 2019 patients.

Sesamoid bones of the hand: A multicenter study.

Objectives: This study aims to document a detailed investigation on the sesamoid bones (SBs) of Turkish subjects from different parts of Turkey in a multi-center study, in both hands, according to gender, frequency and divisions of the bones' coexistence and bilaterality by radiography.

Patients And Methods: This retrospective and three-centered study was performed between June 2010 and April 2012. Sesamoid bones were examined by anteroposterior and oblique X-rays of 1,444 hands of 772 subjects (367 males, 405 females; mean age 42.

Middle Lobe Syndrome Associated with Bronchial Anthracofibrosis.

Bronchial anthracofibrosis has been defined as airway narrowing associated with dark pigmentation on bronchoscopy without an appropriate history of pneumoconiosis or smoking. We present a case of a 67-year-old, non-smoking female patient who was referred to our clinic for two years of persistent cough. Spirometry was within normal limits.

Detection and differential diagnosis of hepatic masses using pulse inversion harmonic imaging during the liver-specific late phase of contrast enhancement with Levovist.

Purpose: The purpose of this study was to investigate whether late-phase pulse inversion harmonic imaging (PIHI) increases conspicuity in hepatic masses, helps to differentiate benign from malignant lesions, and demonstrates a greater number of and smaller metastatic lesions than do conventional (fundamental) sonography and helical CT.

Methods: Thirty patients (17 women and 13 men; age range, 35-77 years; mean age, 54 years) with known or suspected liver masses were evaluated using both fundamental sonography and contrast-enhanced PIHI during the liver-specific late phase of Levovist. The patients also underwent contrast-enhanced triphasic helical CT examinations within 1 week after sonography.
