Optimizing radiology remote reading: leveraging technology to improve efficiency.

Remote work has been increasingly utilized in the profession of radiology over recent years. Setting up your individual workstation offers an opportunity to tailor it to suit your preferences without the restriction of a universal setup to accommodate multiple users. Important considerations when setting up a home workstation include selecting the optimal work location, choosing the proper desk and chair, and configuring an ideal computer monitor layout. The use of peripheral devices, such as programmable mice and hands-free dictation tools can improve efficiency and reduce repetitive strain injuries. This article also explores the use of smart home devices and programmable scripts using AutoHotKey to further streamline workflow and maximize the benefits of a remote workstation.

Prostatic Urethral Length on MRI Potentially Predicts Late Genitourinary Toxicity After Prostate Cancer Radiation.

RATIONALE AND OBJECTIVES: The purpose of our study was to evaluate pretreatment prostate quantitative magnetic resonance imaging (MRI) measurements and clinical characteristics in predicting genitourinary (GU) toxicity after radiotherapy (RT) for prostate cancer. MATERIALS AND METHODS: In this single-institution retrospective cohort study, we evaluated patients with prostate adenocarcinoma who underwent MRI within 6 months before completing definitive RT and follow-up information in our GU toxicity database from June 2016 to February 2023. MRI measurements included quantitative urethra, prostate, and bladder measurements. GU toxicity was physician-scored using the Common Terminology Criteria for Adverse Events (CTCAE v4.0) with acute toxicity defined as ≤180 days and late defined as >180 days. Multivariable logistic regression model was constructed for grade ≥2 acute toxicity and Cox proportional hazards regression for late toxicity, adjusted for clinical factors and RT method. RESULTS: A total of 361 men (median age 68 years, interquartile range [IQR] 62-73) were included; 14.4% (50/347) men experienced grade ≥2 acute toxicity. Brachytherapy (odds ratio [OR]: 2.9, 95% confidence interval [CI]: 1.5-5.8), P < 0.01) was associated with increased odds of acute GU toxicity, and longer MUL (OR: 0.41 [95%CI: 0.18-0.92], P = 0.03) with decreased odds. Median follow-up for late toxicity was 15.0 months (IQR: 9.0-28.0) with approximately 88.7% and 72.0% patients free of toxicity at 1 and 3 years, respectively. Only longer prostatic urethral length (hazard ratio [HR]: 1.6, 95%CI: 1.2-2.1, P < 0.01) was associated with increased risk of late GU toxicity, notably urinary frequency/urgency symptoms (HR: 1.7 [95%CI: 1.3-2.3], P < 0.01). CONCLUSION: Longer prostatic urethral length measured on prostate MRI is independently associated with higher risk of developing late grade ≥2 GU toxicity after radiation therapy for prostate cancer. This pretreatment metric may be potentially valuable in risk-stratification models for quality of life following prostate RT.

Factors influencing the total procedure time of CT-guided percutaneous core-needle biopsies of lung nodules: a retrospective analysis.

PURPOSE This study aims to investigate the factors that influence total procedure time when performing computed tomography (CT)-guided percutaneous core-needle lung biopsies. METHODS This is a cross-sectional study of 673 patients, who underwent a CT-guided percutaneous coreneedle biopsy at a tertiary care center from March 2014 to August 2016. Data on patient, nodule, and procedural factors and outcomes were collected retrospectively. Univariate linear regression and a multivariate stepwise linear regression were utilized for analysis. RESULTS Factors most strongly associated with prolonged procedure duration include 20-gauge needle use when compared with 18-gauge needle use (estimated difference in time=1.19), collecting additional core biopsies (estimated difference in time=1.10), decubitus nodule side up (DNSU; estimated difference in time=1.42), and supine positioning (estimated difference in time=1.16) relative to decubitus nodule side down positioning, and increased nodule distance from the skin surface (estimated difference in time=1.03). Increased nodule length (estimated difference in time=0.93) was associated with reductions in procedure duration. Prolonged procedure time was associated with an increased rate of pneumothorax (odds ratio (OR)=1.02; P < .0001) and decreased rate of pulmonary hemorrhage (OR=0.97; P < .0001). CONCLUSION The use of 20-gauge biopsy needle, collecting additional core biopsies, DNSU and supine positioning, smaller nodule size, and increasing nodule distance from the skin surface were associated with increased procedure time for CT-guided core needle biopsies of lung nodules. Prolonged procedure time is associated with a higher rate of pneumothorax and a lower rate of pulmonary hemorrhage.

Risk Factors for Pneumothorax Development Following CT-Guided Core Lung Nodule Biopsy.

BACKGROUND: This study aims to correlate nodule, patient, and technical risk factors less commonly investigated in the literature with pneumothorax development during computed tomography-guided core needle lung nodule biopsy. PATIENTS AND METHODS: Retrospective data on 671 computed tomography-guided percutaneous core needle lung biopsies from 671 patients at a tertiary care center between March 2014 and August 2016. Univariate and multivariable logistic regression analyses were used to identify pneumothorax risk factors. RESULTS: The overall incidence of pneumothorax was 26.7% (n=179). Risk factors identified on univariate analysis include anterior [odds ratio (OR)=1.98; P<0.001] and lateral (OR=2.17; P=0.002) pleural surface puncture relative to posterior puncture, traversing more than one pleural surface with the biopsy needle (OR=2.35; P=0.06), patient positioning in supine (OR=2.01; P<0.001) and decubitus nodule side up (OR=2.54; P=0.001) orientation relative to decubitus nodule side down positioning, and presence of emphysema in the path of the biopsy needle (OR=3.32; P<0.001). In the multivariable analysis, the presence of emphysematous parenchyma in the path of the biopsy needle was correlated most strongly with increased odds of pneumothorax development (OR=3.03; P=0.0004). Increased body mass index (OR=0.95; P=0.001) and larger nodule width (cm; OR=0.74; P=0.02) were protective factors most strongly correlated with decreased odds of pneumothorax development. CONCLUSION: Emphysema in the needle biopsy path is most strongly associated with pneumothorax development. Increases in patient body mass index and width of the target lung nodule are most strongly associated with decreased odds of pneumothorax.

Pneumothorax Rate and Diagnostic Adequacy of Computed Tomography-guided Lung Nodule Biopsies Performed With 18 G Versus 20 G Needles: A Cross-Sectional Study.

PURPOSE: Conflicting data exist with regard to the effect of needle gauge on outcomes of computed tomography (CT)-guided lung nodule biopsies. The purpose of this study was to compare the complication and diagnostic adequacy rates between 2 needle sizes: 18 G and 20 G in CT-guided lung nodule biopsies. MATERIALS AND METHODS: This retrospective cohort study examined CT-guided lung biopsies performed between March 2014 and August 2016 with a total of 550 patients between the ages of 30 and 94. Biopsies were performed using an 18-G or a 20-G needle. Procedure-associated pneumothorax and other complication rates were compared between the 2 groups. Univariate and multiple logistic regression analyses were performed. RESULTS: There was no significant difference in pneumothorax rate between 18 G (n=125) versus 20 G (n=425) (rates: 25.6% vs. 28.7%; P=0.50; odds ratio [OR]=0.86; 95% confidence interval [CI]=0.54-1.35), chest tube insertion rate (4.8% vs. 5.6%; P=0.71; OR=0.84; 95% CI=0.34-2.11), or diagnostic adequacy (95% vs. 93%; P=0.36; OR=1.51; 95% CI=0.61-3.72). Multiple logistic regression analysis demonstrated emphysema along the biopsy path (OR=3.12; 95% CI=1.63-5.98) and nodule distance from the pleural surface ≥4 cm (OR=1.85; 95% CI=1.05-3.28) to be independent risk factors for pneumothorax. CONCLUSION: No statistically significant difference in pneumothorax rate or diagnostic adequacy was found between 18-G versus 20-G core biopsy needles. Independent risk factors for pneumothorax include emphysema along the biopsy path and nodule distance from the pleural surface.

A Retrospective Evaluation of Time to Obtain an MRI for English- Versus Non-English-Speaking Patients.

PURPOSE: Americans with limited English proficiency (LEP) face significant barriers to health care that result in health disparities in the LEP population. LEP could delay an MRI, potentially increasing morbidity and mortality in the LEP population. This study compares the time to obtain a neurological MRI in English versus non-English language preference patients. METHODS: 24,219 unique patients at a single health system who underwent inpatient neurological MRI were included in the study. Bivariate and multivariate analyses were used to identify characteristics predictive of time to examination (TTE) from the set: patient-preferred language, gender, race, age, performing hospital, and order priority (routine versus stat). RESULTS: Bivariate analysis showed a longer TTE is associated with increasing age category, non-English language preference, and routine priority. A multivariate analysis showed non-English language preference effect on TTE is reduced in magnitude and is no longer significant in a model that includes age group, priority, and hospital (P = .23, effect estimate = 4%, 95% CI: -2.5%, 11.0%). Routine order priority (P < .0001) and increasing age (P < .0001) were associated with increased TTE. In a model that included interactions, the effect of language preference did not depend on order priority (P = .59) or age group (P = .11). CONCLUSION: There is no significant difference in the time to obtain a neurological MRI in English versus non-English language preference patients when age, order priority, and performing hospital are accounted for. This finding supports the effectiveness of the protocols and resources in place to support patients with LEP at the sponsoring health system.
