Comparison of coronary CT angiography and invasive coronary angiography results.

Introduction: Coronary artery disease (CAD) is a leading cause of death worldwide. Accurate diagnosis and management are critical. Non-invasive imaging, such as coronary computed tomography angiography (CCTA), is vital for early diagnosis and treatment planning.

Relation between anterior ethmoidal artery course on computed tomography and supraorbital ethmoid cell and Keros classification.

Purpose: The anterior ethmoidal artery (AEA) is an important risk area in endoscopic sinus surgery. This study aimed to evaluate the course of AEA according to the Keros classification and the presence of supraorbital ethmoid cell (SOEC) and to prevent possible complications by emphasizing the importance of preoperative paranasal computed tomography (CT) imaging. This approach will increase the effectiveness of endoscopic sinus surgery and improve patient safety.

Evaluation of thyroid Zuckerkandl tubercle by computed tomography.

Purpose: This study investigated the incidence of thyroid Zuckerkandl Tubercle (ZT) using a computed tomography (CT) scan of the neck with contrast to identify the typologies in ZT-positive CT scans, investigate the presence of nodules located in that area, and compare the results with the relevant literature.

Methods: We selected and retrospectively examined the CT scan images of patients who presented to our clinic with CT scans of the neck with contrast that clearly showed thyroid tissue and boundaries. Patients were evaluated based on age, gender, and presence of thyroid ZT.

Comparison of Efficiencies Between Shear Wave Elastography, Fine-Needle Aspiration Biopsy and American College of Radiology Thyroid Imaging Reporting and Data System Scoring System in Determining the Malignity Potential of Solid Thyroid Nodules.

We aimed to evaluate the efficiencies of quantitative shear-wave elastography, fine-needle aspiration (FNA) biopsy and American College of Radiology (ACR)-thyroid imaging reporting and data system (TIRADS) scoring system in determining the malignity potential of solid thyroid nodules. In period between September 2014 and January 2016, 191 solid thyroid nodules of 189 patients were enrolled in this study. The mean shear wave velocities of the nodules were recorded by acoustic radiation force impulse method.

Usability of Transthoracic Shear Wave Elastography in Differentiation of Subpleural Solid Masses.

In this study, the effectiveness of transthoracic ultrasound elastography in the benign and malign distinction of subpleural/pleural solid lesions was investigated.Between July 2015 and December 2016, 33 consecutive patients with subpleural solid lesions detected via computed tomography (CT) of the thorax were identified and prospectively included in this study. The average for each lesion's shear wave velocity (SWV) value was detected, and benign and malignant lesions' SWV values are statistically compared.

Acoustic radiation force impulse elastosonography of placenta in maternal red blood cell alloimmunization: a preliminary and descriptive study.

Aims: Maternal red blood cell alloimmunization is an important cause of fetal morbidity and mortality in the perinatal period, despite well-organized prophylaxis programs. The objective of the study was to evaluate placental elasticity by using Acoustic Radiation Force Impulse (ARFI) in Rhesus (Rh) alloimmunized pregnant women with hydropic and nonhydropic fetuses and to compare those with healthy pregnant women.

Material And Methods: This case-control and descriptive study comprised twenty-eight healthy pregnant women, 14 Rh alloimmunized pregnant women with nonhydropic fetuses, and 16 Rh alloimmunized pregnant women with hydropic fetuses in the third trimester of pregnancy.

Maternal liver elasticity determined by acoustic radiation force impulse elastosonography in intrahepatic cholestasis of pregnancy.

Purpose: Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific liver disorder characterized by maternal pruritus and impaired liver function. The objective of the study was to evaluate maternal liver elasticity by acoustic radiation force impulse (ARFI) elastosonography in ICP and to compare it with that in healthy pregnant women.

Methods: This descriptive, case-control study consisted of 33 women with healthy pregnancies and 22 women with ICP in the third trimester of gestation.

Comparison of placental elasticity in normal and pre-eclamptic pregnant women by acoustic radiation force impulse elastosonography.

Aim: The aim of this research was to study and compare placental elasticity with acoustic radiation force impulse (ARFI) elastography in pre-eclamptic and normal pregnancies.

Methods: A total of 107 singleton pregnancies in the third trimester (38 healthy control subjects, 34 patients with gestational hypertension, and 35 pre-eclampsia patients) were included in the study. ARFI elastography was used to determine the placental elasticity in the three predetermined regions of the placenta (the fetal edge, maternal edge, and central part of the placenta).

Evaluation of maternal liver elasticity by acoustic radiation force impulse elastosonography in hypertensive disorders of pregnancy: a preliminary descriptive study.

Purpose: To compare maternal liver elasticity scores by Acoustic Radiation Force Impulse (ARFI) elastosonography in healthy and preeclamptic pregnancies and its association with the severity of the disease.

Materials And Methods: Forty-two healthy, 33 mild, 33 severe preeclamptic and 28 pregnant women with Hemolysis, Elevated Liver enzymes and Low Platelets (HELLP) syndrome were included into the study. Maternal liver elasticity was measured by ARFI elastosonography at the first day of puerperium.
