Dual-energy computed tomography pulmonary angiography with ultra-low dose contrast administration: Comparison of image quality with standard computed tomography pulmonary angiography.

Background: This study aims to compare quantitative and qualitative image quality between standard computed tomography pulmonary angiography and dual-energy computed tomography pulmonary angiography protocols.

Methods: Between September 2017 and August 2018, a total of 91 consecutive patients (34 males, 57 females; mean age: 65.9±15 years; range, 37 to 91 years) who were referred for computed tomography pulmonary angiography were randomly imaged with either a standard or dual-energy protocol.

Virtual contrast enhancement for CT scans of abdomen and pelvis.

Contrast agents are commonly used to highlight blood vessels, organs, and other structures in magnetic resonance imaging (MRI) and computed tomography (CT) scans. However, these agents may cause allergic reactions or nephrotoxicity, limiting their use in patients with kidney dysfunctions. In this paper, we propose a generative adversarial network (GAN) based framework to automatically synthesize contrast-enhanced CTs directly from the non-contrast CTs in the abdomen and pelvis region.

Ultrasound-guided versus blind subacromial corticosteroid and local anesthetic injection in the treatment of subacromial impingement syndrome: A randomized study of efficacy.

Objectives: This study aims to compare the effects of ultrasound (US)-guided and blind subacromial corticosteroid and local anesthetic (LA) injection in the treatment of subacromial impingement syndrome (SIS) on shoulder pain, range of motion (ROM), and functionality.

Patients And Methods: The prospective study was conducted between 01 February 2017 and 31 May 2017. A total of 29 patients with clinical findings and magnetic resonance imaging (MRI) consistent with SIS were randomized into two groups: 14 patients received US-guided subacromial corticosteroid and LA injection and 15 patients received a blind subacromial corticosteroid and LA injection.

Diagnostic Analysis of Computed Tomography Patterns in Patients With Invasive Pulmonary Aspergillosis After Solid-Organ Transplantation.

Objectives: The aim of this study was to assess initial and follow-up computed tomography findings of invasive pulmonary aspergillosis in solid-organ transplant recipients and to examine the most common computed tomography patterns during hospitalization.

Materials And Methods: From January 2011 to September 2016, the total number of solid-organ transplant patients at our institution was 784. These patients consisted of 550 kidney, 164 liver, and 67 heart transplant recipients.

Partial Splenic Torsion : Revealed by Ultrasound and Computed Tomography.

We present a case of acute abdominal pain due to partial torsion of spleen located in its own normal anatomical position in a 20-year-old woman, diagnosed by ultrasound and confirmed on computed tomography and treated laparoscopically.

Liver Perivascular Epithelioid Cell Tumor with an Unusual Location: Diagnostic Characteristics with Multidetector Computed Tomography and Magnetic Resonance Imaging.

Primary perivascular epithelioid cell tumor (PEComa) of the liver is a very rare tumor that originates from mesenchyma. Gastrointestinal tract with perivascular distribution is the most common anatomic sites of these tumors. Only few cases of hepatic PEComa have been described so far.
