Diagnostic value of shear wave velocity in polycystic ovarian syndrome.

In polycystic ovarian syndrome, the ovaries become stiffer due to chronic anovulation. We aimed to compare tissue elasticity in terms of shear wave velocities measured using acoustic radiation force impulse imaging technique between the ovaries of polycystic ovarian syndrome women and non-polycystic ovarian syndrome women. The study was designed as a retrospective data analysis of women who underwent transvaginal ultrasound and acoustic radiation force impulse imaging in a university hospital between July 2014 and March 2015, for various reasons.

Endovascular Recanalization of the Chronically Occluded Native Superficial Artery After Failed Bypass Graft: Midterm Results.

Purpose: To evaluate the safety, effectiveness, and outcomes of endovascular recanalization of chronic total occlusion (CTO) of the superficial femoral artery (SFA) in patients with critical limb ischemia (CLI) after failed surgical bypass graft.

Methods: Endovascular recanalization of SFA CTO was performed for 26 consecutive CLI patients with failed bypass grafts from 2016 to 2020. Patient demographics, bypass and lesion characteristics, procedural data, technical, and clinical outcomes were evaluated.

Endovascular recanalization and remodeling of abdominal aorta stent graft chronic total occlusion after failed extra-anatomic bypass surgery.

Objectives: Chronic total occlusion (CTO) of the EVAR graft is a rare and serious complication. Traditionally, surgical intervention with prosthetic graft replacement or bypass graft implantation is performed. However, there are limited data in endovascular era.

The Feasibility of Low-dose Chest CT Acquisition Protocol for the Imaging of COVID-19 Pneumonia.

Objective: This study aimed to investigate the feasibility of low-dose chest CT acquisition protocol for the imaging of COVID 19 disease or suspects of this disease in adults.

Methods: In this retrospective case-control study, the study group consisted of 141 patients who were imaged with low dose chest CT acquisition protocol. The control group consisted of 92 patients who were imaged with standard protocol.

Transhepatic Pharmacomechanical Thrombectomy of Symptomatic Acute Noncirrhotic, Nonmalignant Portomesenteric Venous Thrombosis: Midterm Results.

The purpose of this study was to evaluate the safety and efficacy of transhepatic pharmacomechanical thrombectomy of symptomatic acute portomesenteric venous thrombosis. Transhepatic pharmacomechanical thrombectomy (catheter-directed thrombolysis with mechanical thrombectomy) was performed in the treatment of nine patients with symptomatic acute noncirrhotic, nonmalignant porto-mesenteric venous thrombosis. The medical records, imaging examinations, technique of transhepatic pharmacomechanical thrombectomy, and clinical outcomes were reviewed.

The Prevalence of Open and Closed Posterior Superior Iliac Spine.

Aim: To determine the prevalence of open and closed posterior superior iliac spine (PSIS) using lower abdominal computed tomography (CT) examinations.

Material And Methods: Eight hundred and fifty (M/F:464/386) adult patients who underwent lower abdominal CT between January 2018 and December 2018 were evaluated retrospectively. One radiologist reviewed CT images of patient pelvises to assess the presence of open and closed PSIS.

Radiation doses from head, neck, chest and abdominal CT examinations: an institutional dose report.

Purpose: We aimed to obtain typical values for head, neck, chest, and abdominal computed tomography (CT) examinations from routine patients in 2018, and to review our data with national and international diagnostic reference levels (DRLs).

Methods: Single-phase head, neck, chest, and abdominal CT scans of adults performed in 64-slice CT in 2018 were included in this study. Radiation dose parameters of CT scans were obtained from the picture archiving and communication system of our hospital.

Endovascular Treatment of Critical Limb Ischemia in Buerger Disease (Thromboangiitis Obliterans) With Midterm Follow-Up: A Viable Option When Bypass Surgery Is Not Feasible.

Thromboangiitis obliterans (TAO) is an occlusive inflammatory disease affecting small- and medium-sized vessels that causes decrease in life quality and eventually limb loss. The only proven treatment method is smoking cessation, but it may be insufficient for limb salvage in patients with critical limb ischemia. In this single-center retrospective study, the feasibility and efficiency of endovascular treatment in TAO were evaluated.

Percutaneous endobiliary ablation of malignant biliary strictures with a novel temperature-controlled radiofrequency ablation device.

Purpose: We aimed to determine the safety and effectiveness of percutaneous endobiliary radiofrequency ablation of malignant biliary obstructions with a temperature-controlled radiofrequency ablation device.

Methods: In this single center retrospective study, a total of 62 consecutive patients with malignant biliary obstruction were evaluated. Thirty patients who underwent endobiliary radiofrequency ablation with metallic stent placement were in the study group and 32 patients who underwent only metallic stenting were in the control group.

Retrograde Pedal Access via Occluded Arteries in Endovascular Treatment of Critical Limb Ischemia.

Purpose: To evaluate the feasibility and technical outcomes of retrograde access via occluded pedal arteries in endovascular treatment of critical limb ischemia (CLI) when the conventional antegrade approach fails.

Materials And Methods: One hundred fifty-one patients with CLI (age 69 y ± 10.5; 116 men) who were not surgical candidates and were treated via retrograde pedal access between January 2016 and January 2018 were evaluated retrospectively.

Percutaneous Intraductal Microwave Ablation of Malignant Biliary Strictures: Initial Experience.

Metallic stenting of malignant biliary strictures is the preferred method of palliation, because most patients present when the condition is inoperable. Most metallic stents, however, are occluded 6-8 months after deployment. Intraductal radiofrequency ablation has been used in previous studies to improve stent patency.

Achilles tendon elasticity decreases with intermittent claudication in patients by Acoustic Radiation Force Impulse Imaging (ARFI).

Objective: To investigate the value of Acoustic Radiation Force Impulse elastography and its application in Achilles tendon elasticity of intermittent claudication due to lower extremity arterial ischaemia.

Methods: This prospective case-control study was conducted at the Department of Radiology, Faculty of Medicine, Baskent University, Istanbul, Turkey, from October 2015 to January 2016, and comprised bilateral Achilles tendons of patients with intermittent claudication and healthy individuals. Shear-Wave Velocity (SWV) of each tendon was measured using Acoustic Radiation Force Impulse elastography.

Simultaneous Immunoglobulin G4-associated Autoimmune Hepatitis and Autoimmune Pancreatitis.

Value of in vitro acoustic radiation force impulse application on uterine adenomyosis.

Purpose: Adenomyosis is the presence of endometrial glandular and stromal tissue in the myometrium. This phenomenon can be the cause of excessive bleeding and menstrual pain in premenopausal women. Diagnosis of adenomyosis may present difficulty with conventional methods such as ultrasound and magnetic resonance imaging.
