Implementation of abbreviated breast MRI in diagnostic and screening settings.

Background: Abbreviated magnetic resonance imaging (MRI) includes fewer sequences than standard MRI, which could be utilized for breast cancer detection.

Purpose: To evaluate the diagnostic accuracy of abbreviated MRI protocol in screening and diagnostic settings.

Material And Methods: All women with screening and diagnostic (problem-solving and preoperative staging) MRI examination were recruited from 2017 to 2020.

Cluster analysis of insomnia symptoms during COVID-19 pandemic: a general population web-based survey in Iran.

Objective: To investigate the prevalence of insomnia and its different phenotypes as well as their association with fear of COVID-19 in the general population.

Material And Methods: This was a cross-sectional study conducted using an online survey (e-poll). All available participants who completed the online survey form were included in the current study.

Percutaneous Sclerotherapy with Bleomycin and Ethiodized Oil: A Promising Treatment in Symptomatic Giant Liver Hemangioma.

Background Percutaneous sclerotherapy with bleomycin has been proven to have a potential benefit in the management of low-flow venous malformations. Liver hemangiomas are considered low-flow venous malformations. Thus, percutaneous sclerotherapy could potentially have a promising result in their management.

Sex Differences are Reflected in Microstructural White Matter Alterations of Musical Sophistication: A Diffusion MRI Study.

The human-specified ability to engage with different kinds of music in sophisticated ways is named "Musical Sophistication." Herein, we investigated specific white matter (WM) tracts that are associated with musical sophistication and musicality in both genders, separately, using Diffusion MRI connectometry approach. We specifically aimed to explore potential sex differences regarding WM alterations correlated with musical sophistication.

Factors Predicting Outcome in Intensive Care Unit-Admitted COVID-19 Patients: Using Clinical, Laboratory, and Radiologic Characteristics.

Purpose: To investigate the factors contributing to mortality in coronavirus disease 2019 (COVID-19) patients admitted in the intensive care unit (ICU) and design a model to predict the mortality rate.

Method: We retrospectively evaluated the medical records and CT images of the ICU-admitted COVID-19 patients who had an on-admission chest CT scan. We analyzed the patients' demographic, clinical, laboratory, and radiologic findings and compared them between survivors and nonsurvivors.

Shift Work Disorder, Insomnia, and Depression among Offshore Oil Rig Workers.

Numerous offshore jobs require 24-hour tasks, such as in industrial workplaces (eg, oil rigs). The purpose of this study was to assess shift work disorder (SWD), insomnia, daytime sleepiness, and depression among Iranian offshore oil rig workers in different shift schedules. This cross-sectional study was conducted on Iranian offshore oil workers at the Persian Gulf.

Sex differences in microstructural white matter alterations of mathematics anxiety based on diffusion MRI connectometry.

Background: Mathematics Anxiety (MA) is a feeling of stress, tension, and fear in situations engaging with math-related tasks. Herein, we utilized Diffusion Magnetic Resonance Imaging (DMRI) connectometry approach to tracking white matter (WM) fibers with a significant correlation with the severity of MA.

Methods: A total of 77 healthy adult participants (50 males, mean age ± SD = 26.

Clinical and chest CT features as a predictive tool for COVID-19 clinical progress: introducing a novel semi-quantitative scoring system.

Objective: Proposing a scoring tool to predict COVID-19 patients' outcomes based on initially assessed clinical and CT features.

Methods: All patients, who were referred to a tertiary-university hospital respiratory triage (March 27-April 26, 2020), were highly clinically suggestive for COVID-19 and had undergone a chest CT scan were included. Those with positive rRT-PCR or highly clinically suspicious patients with typical chest CT scan pulmonary manifestations were considered confirmed COVID-19 for additional analyses.

Biofluid Biomarkers in Traumatic Brain Injury: A Systematic Scoping Review.

Emerging evidence suggests that biofluid-based biomarkers have diagnostic and prognostic potential in traumatic brain injuries (TBI). However, owing to the lack of a conceptual framework or comprehensive review, it is difficult to visualize the breadth of materials that might be available. We conducted a systematic scoping review to map and categorize the evidence regarding biofluid-based biochemical markers of TBI.

Esophageal variceal hemorrhage: the role of MDCT characteristics in predicting the presence of varices and bleeding risk.

Purpose: To investigate the associated Multi-Detector Computed Tomography (MDCT) features for esophageal varices (EVs) and esophageal variceal hemorrhage (EVH), with particular emphasis on different collateral veins.

Materials And Methods: All cirrhotic patients who had undergone both Upper Gastrointestinal Tract (UGIT) endoscopy and contrast-enhanced MDCT within 6 months from 2013 to 2019 were included in the study. MDCT of 124 patients, 76 males and 48 females, aged between 21 and 73 years old were evaluated for presence of EV and presence and size of different collaterals.

Multimodality treatment in unresectable cholangiocarcinoma.

Purpose: Cholangiocarcinomas (CCs) are rare and highly malignant cancers. Although there are different treatment protocols for treatment of cholangiocarcinoma, we aimed to investigate a survival rate of patients with unresectable extrahepatic CCs (ECCs) receiving multimodality therapeutic protocol (MTP) (biliary drainage + external beam radiotherapy [EBRT] + brachytherapy and systemic chemotherapy). Similarly, we aimed to identify a relationship between survival time and associated factors in treatment outcome.

Intractable parastomal bleeding in a portal hypertensive patient managed by direct sclerotherapy: a case report.

Patients with a stoma have 5% chance of developing parastomal varices, which tend to repetitive massive and life-threatening hemorrhages. Treatment of choice in parastomal varices have not been established, while Transjugular Intrahepatic Portosystemic Shunt (TIPS) has been revealed as the most successful measure. We report a hemodynamically unstable patient with a history of Ulcerative Colitis (UC) and Primary Sclerosing Cholangitis (PSC) with colostomy, because of colon cancer who presented with massive parastomal bleeding.

Pancreatic neuroendocrine tumors (pNETs): the predictive value of MDCT characteristics in the differentiation of histopathological grades.

Purpose: To investigate the correlation between multiple detector computed tomography (MDCT) features of pancreatic neuroendocrine tumors (pNETs) and histopathologic grade and find valuable imaging criteria for grade prediction.

Material And Methods: MDCT of 61 patients with 65 masses, which pNETs were approved histopathologically, underwent revision retrospectively. Each MDCT was evaluated for various radiologic characteristics.
