The surging demand for diagnostic imaging has highlighted inefficiencies with traditional input devices. Radiologists, using conventional mice and keyboards, grapple with cumbersome shortcuts leading to fatigue, errors, and possible injuries. Gaming keyboards, designed for gamers' precision and adaptability, feature customizable keys that simplify complex tasks into single-touch actions, offering radiologists a more efficient workflow with less physical and mental strain.

The increasing demand for diagnostic imaging has added to the radiologists' workload, highlighting the shortcomings of conventional computer mice. Radiologists grapple with inefficiencies from frequent mouse clicks and keyboard shortcuts required for various PACS functions. These inefficiencies contribute to cognitive strain, errors, and repetitive strain injuries.

Objective: The aim of this study was to evaluate the utility of appendicular skeleton magnetic resonance imaging (MRI) in the management of multiple myeloma over 15 years.

Methods: A total of 107 appendicular MRIs were obtained from 67 patients. Variables including age, sex, diagnosis, stage, indication, transplant status, MRI result, and treatment course were analyzed.

The presence of extraprostatic extension (EPE) on multiparametric MRI (mpMRI) is an important factor in determining the management of prostate cancer. EPE is an established risk factor for biochemical recurrence of prostate cancer after radical prostatectomy (RP) and patients with EPE may be considered for wider resection margins, non-nerve-sparing surgery, adjuvant radiation therapy (RT), or androgen deprivation therapy (ADT). Several statistical nomograms and scoring systems have been developed to predict pathological stage at time of RP but with varying accuracies.

Purpose: To evaluate clinical, laboratory, imaging, endoscopic findings, treatment, and outcomes of patients with CMV colitis.

Methods: The electronic medical records of 652 patients who had an impression of colitis of unspecified etiology via endoscopic findings between 2011 and 2019 were retrospectively reviewed. There were 9 patients with biopsy-proven CMV colitis and associated CT imaging performed within 1 month of diagnosis.

Purpose: To determine the frequency, imaging, and clinical manifestations of immune checkpoint inhibitor (ICI)-related colitis in cancer patients on monotherapy or combination therapy.

Methods: The electronic medical records of 1044 cancer patients who received ICIs were retrospectively reviewed to identify 48 patients who had a clinical diagnosis of immune-related colitis. Imaging studies were reviewed to identify patients with imaging manifestations of colitis.

The purpose of this article is to provide for radiologists an overview of the radiologic, clinical, and pathologic features of hemophagocytic lymphohistiocytosis. Hemophagocytic lymphohistiocytosis is a rare, life-threatening syndrome characterized by abnormal, excessive activation of the immune system. Imaging plays an important role in determining the extent of involvement of hemophagocytic lymphohistiocytosis.

Purpose: To longitudinally evaluate for changes in globe position as part of the natural aging process.

Methods: A Cleveland Clinic Foundation imaging database of all head imaging scans performed from 1995 to 2017 was used to identify adults with normal orbits undergoing imaging studies at least 20 years apart. A total of 100 patients (200 globes) who had CT or MRI scans were studied.

Bioactive lipids such as sphingosine-1-phosphate (S1P) and lysophosphatidic acid (LPA) regulate diverse processes including cell proliferation, differentiation, and migration. However, their roles in cardiac differentiation and cardiomyocyte proliferation have not been explored. Using a 96-well differentiation platform for generating human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) we found that S1P and LPA can independently enhance cardiomyocyte generation when administered at an early stage of differentiation.

As the basic unit of living organisms, each single cell has unique molecular signatures and functions. Our ability to uncover the transcriptional and epigenetic signature of single cells has been hampered by the lack of tools to explore this area of research. The advent of microfluidic single cell technology along with single cell genome-wide DNA amplification methods had greatly improved our understanding of the expression variation in single cells.

Many studies have identified metabolic pathways that underlie cellular transformation, but the metabolic drivers of cancer progression remain less well understood. The Hippo transducer pathway has been shown to confer malignant traits on breast cancer cells. In this study, we used metabolic mapping platforms to identify biochemical drivers of cellular transformation and malignant progression driven through RAS and the Hippo pathway in breast cancer and identified platelet-activating factor acetylhydrolase 1B3 (PAFAH1B3) as a key metabolic driver of breast cancer pathogenicity that is upregulated in primary human breast tumors and correlated with poor prognosis.
