Objectives: To explore the topic of Prostate Imaging-Reporting and Data System (PI-RADS) interobserver variability, including a discussion of major sources, mitigation approaches, and future directions.

Methods: A narrative review of PI-RADS interobserver variability.

Results: PI-RADS was developed in 2012 to set technical standards for prostate magnetic resonance imaging (MRI), reduce interobserver variability at interpretation, and improve diagnostic accuracy in the MRI-directed diagnostic pathway for detection of clinically significant prostate cancer.

Rationale And Objectives: To investigate the effect of resident-run wellness retreats on measures of stress, resilience, and cohesion amongst radiology residents.

Materials And Methods: All diagnostic and interventional radiology residents in a single academic medical center were invited to participate in a wellness-focused off-campus retreat. Three retreats were held on an annual basis from 2018 to 2022 and included physical exercises, nutritional wellness, and team-building activities.

The detection of incidental pancreatic cystic lesions has increased over time. It is crucial to separate benign from potentially malignant or malignant lesions to guide management and reduce morbidity and mortality. The key imaging features used to fully characterize cystic lesions are optimally assessed by contrast-enhanced magnetic resonance imaging/magnetic resonance cholangiopancreatography, with pancreas protocol computed tomography offering a complementary role.

Rationale And Objectives: Traditional approaches towards teaching magnetic resonance imaging (MRI) scanning and physics have limitations that a hands-on course may help overcome. A dedicated week of MRI instruction may help improve radiology resident confidence and competence. Additional benefits may include improved physician-technologist communication and accelerated mastery of MRI safety.

Purpose: Natural language processing (NLP) applied to radiology reports can help identify clinically relevant M1 subcategories of patients with colorectal cancer (CRC). The primary purpose was to compare the overall survival (OS) of CRC according to American Joint Committee on Cancer TNM staging and explore an alternative classification. The secondary objective was to estimate the frequency of metastasis for each organ.

Objectives: To investigate what findings are new on contrast-enhanced abdominopelvic CT in patients infected with SARS-CoV-2.

Methods: Contrast-enhanced CT of the abdomen and pelvis of patients with COVID-19 at a tertiary oncologic center acquired over a 2-month period were reviewed independently by two readers and scored for new imaging abnormalities compared with a prior scan. CT scans were included if the study was performed between - 3 and 45 days from the time of COVID-19 diagnosis.

Article Synopsis
  • The study investigates the use of natural language processing (NLP) to analyze radiology reports to understand patterns of metastatic spread in cancer patients, rather than relying on autopsy data.
  • It includes data from 91,665 patients and shows that the best-performing NLP model can accurately identify metastases with up to 99% accuracy across various organs.
  • The findings reveal distinct patterns of metastasis for different types of cancers, emphasizing the importance of location in metastatic spread, which could enhance patient prognostication and treatment planning.

Objective: To determine all-cause mortality risk in patients with and without adrenal incidentaloma.

Methods: Retrospective cohort study of patients with CT abdomen performed within 24 h of emergency room presentation at an academic medical center from January 1, 2005, to December 31, 2009, without history of adrenal disease, adrenal lab testing, or cancer. Incidentaloma cohort identified by database query of imaging reports followed by manual review and matched to no-nodule controls at 3:1 on age ± 1 year and exam date ± 3 months.

Purpose: To compare the distribution of extracolonic findings and clinical outcomes between screening and diagnostic CT colonography (CTC) populations.

Methods: 388 consecutive patients (369 men, 19 women; mean ± SD age 67.8 ± 10 years) who underwent first-time CTC (4/2011-4/2017) at a Veteran's Affairs Medical Center were divided into screening (asymptomatic) or diagnostic (symptomatic) cohorts based on CTC indication.

Artemisinin (ART) dimers show potent anti-proliferative activities against breast cancer cells. To facilitate their clinical development, novel pH-responsive artemisinin dimers were synthesized for liposomal nanoparticle formulations. A new ART dimer was designed to become increasingly water-soluble as pH declines.
