Can T1W and T2W Dixon Sequences Replace the Standard MRI Protocol in Diagnosing Sacroiliitis?

This study aims to assess the performances of T1‑weighted (T1W) and T2‑weighted (T2W) Dixon sequences as replacements for the standard magnetic resonance imaging (MRI) protocol for diagnosing active and chronic sacroiliitis. This single‑centre, prospective study included 107 patients who underwent 3 Tesla MRIs. The patients with inflammatory low‑back pain (aged 18-50 years) were included.

Evaluation of abdominal computed tomography findings in patients with COVID-19: a multicenter study.

Purpose: To evaluate the frequency of abdominal computed tomography (CT) findings in patients with coronavirus disease-2019 (COVID-19) and interrogate the relationship between abdominal CT findings and patient demographic features, clinical findings, and laboratory test results as well as the CT atherosclerosis score in the abdominal aorta.

Methods: This study was designed as a multicenter retrospective study. The abdominal CT findings of 1.

Use of dual energy CT urography in evaluation of urinary stone and complex cyst.

Background: Dual-energy computed tomography scans can provide significant benefits to the urinary system. The aim of this study is to determine the limitations and benefits of using dual energy CT urography in patients with urinary system stones and cysts.

Methods: In the analysis of the images, the virtual noncontrasted images obtained from the combined nephrogenicexcretory phase and the true noncontrasted images were evaluated.

COMPARISON OF TVUS, MRI, AND FROZEN SECTION METHODS IN PREOPERATIVE DETECTION OF MYOMETRIAL INVASION IN PATIENTS WITH ENDOMETRIAL CANCER.

We aimed to evaluate the depth of myometrial invasion preoperatively with transvaginal ultrasound, magnetic resonance imaging, and frozen section examination techniques in patients diagnosed with endometrial cancer. Our study included 65 patients. Transvaginal ultrasound and magnetic resonance imaging were performed in study patients in the preoperative period.

A Novel Physical Examination Test for Ischiofemoral Impingement: Validation With Magnetic Resonance Imaging Correlation.

Objective: The purpose of this study was to propose and validate a novel physical examination test for ischiofemoral impingement with magnetic resonance imaging (MRI) correlation.

Methods: We prospectively studied 24 women with buttock (deep gluteal) pain and 27 asymptomatic women. Each group underwent a 2-stage physical examination test that featured hip adduction-external rotation-extension and knee flexion.

The Value of Superb Microvascular Imaging in Detecting Hepatic Artery Occlusion in Liver Transplantation: A Preliminary Study.

Superb microvascular imaging (SMI) is an innovative color Doppler technique that is used to evaluate low-velocity blood flow in particular. Our purpose in this study was to examine the sensitivity and specificity of SMI for assessing occlusion of the hepatic artery after liver transplantation. Ninety-five prospective patients who underwent liver transplantation were included in our study between April 2014 and February 2018.

Effects of Laparoscopic Hernia Repair by PIRS (Percutan Internal Ring Suturing) Technique on Testicular Artery Blood Supply.

: Percutaneous internal ring suturing technique (PIRS) is a minimally invasive technique in pediatric inguinal hernia repair. In the present study, a negative effect on testicular blood flow using PIRS technique has been investigated. : Forty male patients were included in the study prospectively.

Value of dynamic MRI using the Ktrans technique for assessment of native kidneys in pre-emptive renal transplantation.

Background Different non-invasive imaging techniques such as Doppler ultrasonography and renal scintigraphy are commonly employed to assess allograft function and associated complications. However, all such methods lack sufficient specificity to discriminate between residual renal function of native kidneys. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) evaluates signal dynamics during the passage of contrast material through the renal cortex, medulla, and collecting system.

An Extremely Rare Anatomical Variation: Abnormal Drainage of the Anterior Interventricular Coronary Vein.

Unlabelled: Variation of anterior interventricular vein draining into the left atrium is an extremely rare occurrence. Multidetector computed tomography (MDCT) coronary angiography has recently become the gold standard for depicting anatomical variations and anomalies of coronary arteries and veins. We herein have reported the case of a 36-year-old male whose anterior interventricular vein draining into the left atrium was demonstrated by MDCT coronary angiography.

The Comparison of Computed Tomography Perfusion, Contrast-Enhanced Computed Tomography and Positron-Emission Tomography/Computed Tomography for the Detection of Primary Esophageal Carcinoma.

Objective: The purpose of this study was to investigate the efficiency of computed tomography perfusion (CTP), contrast-enhanced computed tomography (CECT) and 18F-fluoro-2-deoxy-D-glucose (18F-FDG) positron-emission tomography (PET/CT) in the diagnosis of esophageal cancer.

Subjects And Methods: This prospective study consisted of 33 patients with pathologically confirmed esophageal cancer, 2 of whom had an esophageal abscess. All the patients underwent CTP, CECT and PET/CT imaging and the imaging findings were evaluated.

The utility of cardiac magnetic resonance imaging in Kounis syndrome.

Introduction: Current diagnostic measurements used to assess myocardial involvement in Kounis syndrome, such as electrocardiography (ECG), cardiac enzymes, and troponin levels, are relatively insensitive to small but potentially significant functional change. According to our review of the literature, there has been no study using magnetic resonance imaging (MRI) on Kounis syndrome except for one case report.

Aim: To identify the findings of dynamic contrast-enhanced magnetic resonance imaging (CE-MRI) in patients with Kounis syndrome (KS) type 1.

The feasibility of dual-energy CT in differentiation of vertebral compression fractures.

Objective: To prospectively evaluate the ability of dual-energy CT (DECT), compared with MRI, to identify vertebral compression fractures in acute trauma patients.

Methods: This institutional review board-approved study included 23 consecutive patients with 32 vertebral fractures who underwent both DECT and MRI of the spine between February 2014 and September 2014. A total of 209 vertebrae were evaluated for the presence of abnormal bone marrow attenuation on DECT and signal on MRI by five experienced radiologists.
