Accelerated Phase Contrast MRI with Use of Resolution Enhancement Generative Adversarial Neural Network.

Background: Cardiovascular magnetic resonance (CMR) phase-contrast is used to quantify blood flow. We sought to develop a complex-difference reconstruction for inline super-resolution of phase-contrast (CRISPFlow) to accelerate phase-contrast imaging.

Methods: CRISPFlow was built on the super-resolution generative adversarial network.

Utilization of a cloud-based radiology analytics platform to monitor imaging volumes at a large tertiary center.

Rationale And Objective: In this study, we evaluate the ability of a novel cloud-based radiology analytics platform to continuously monitor imaging volumes at a large tertiary center following institutional protocol and policy changes.

Materials And Methods: We evaluated response to environmental factors through the lens of the COVID-19 pandemic. Analysis involved 11 CT/18 MR imaging systems at a large tertiary center.

Hemodynamic Evaluation of Type B Aortic Dissection Using Compressed Sensing Accelerated 4D Flow MRI.

Background: 4D Flow MRI is a quantitative imaging technique to evaluate blood flow patterns; however, it is unclear how compressed sensing (CS) acceleration would impact aortic hemodynamic quantification in type B aortic dissection (TBAD).

Purpose: To investigate CS-accelerated 4D Flow MRI performance compared to GRAPP-accelerated 4D Flow MRI (GRAPPA) to evaluate aortic hemodynamics in TBAD.

Study Type: Prospective.

Pilot Tone-Triggered MRI for Quantitative Assessment of Cardiac Function, Motion, and Structure.

Objective: The aim of this study was to test the hypothesis that there are good agreements between cardiac functional and structural indices derived from magnetic resonance imaging (MRI) sequences triggered with pilot tone (PT) and electrocardiogram (ECG).

Materials And Methods: Sixteen healthy volunteers (11 male, age 21-76 years) underwent a cardiac MRI scan. Cine MRI, T1, and T2 mapping were acquired by using PT and ECG triggering.

The consistency of myocardial strain derived from heart deformation analysis.

The purpose of this study was to assess the consistency of semi-automated myocardial strain analysis by prototype software across field strengths, temporal resolutions, and examinations. 35 volunteers (48 ± 13 years; 20% women) and 25 patients (54 ± 12 years; 44% women) without significant cardiac dysfunction underwent cine cardiac magnetic resonance imaging (CMR) at 1.5 T with a temporal resolution of 39.

Advocacy for women's health should include lesbian health.

Although research confirms that homosexuality is a normal expression of human sexuality, established scientific studies are often not reflected in laws and judicial opinions for lesbians with regard to employment, taxation, pensions, disability, healthcare, immigration, military service, marriage, custody, and adoption. The expression of homosexual attraction or behavior is sometimes met by disdain or violence. Psychological and epidemiological research confirms that the public discriminatory attitudes and second-class legal status cause physical, emotional, and financial harm to lesbians, their families, and their children.

Psychosocial intervention for lesbians with primary breast cancer.

This study examined the effects of a Supportive-Expressive group therapy intervention offered to lesbians with early stage breast cancer. Twenty lesbians diagnosed with breast cancer in the previous 12-months were recruited and assessed at baseline, and at 3, 6, and 12 months after the group intervention. During the 12-week intervention, group members focused on the problems of a new diagnosis, coping with the illness and treatment, mood changes, coping responses and self-efficacy, improving relationships with family, friends and physicians, the impact of the illness on life, pain and sleep, and changes in body image and sexuality.
