Effect of Direct Neuroradiologist Participation in Physician Marketing on Imaging Volumes in Outpatient Radiology [PDF]

American Journal of Neuroradiology, 2014
Over the past several years, decreased demand for and increased supply of imaging services has increased competition among outpatient imaging centers in the United States. This study hypothesizes that using a radiology sales representative and neuroradiologist as a team in marketing and sales will increase imaging referrals in outpatient imaging.From ...

AI‐based localization of the epileptogenic zone using intracranial EEG

Epilepsia Open, EarlyView.
Abstract Artificial intelligence (AI) is rapidly transforming our lives. Machine learning (ML) enables computers to learn from data and make decisions without explicit instructions. Deep learning (DL), a subset of ML, uses multiple layers of neural networks to recognize complex patterns in large datasets through end‐to‐end learning.

Hypervision Proton Surgery: The Future Direction of Proton Therapy

iNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Concordance Between MR Safety Guidance Documents on Conditions for a Safe MR Environment

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Environmental conditions established at facility design, construction, updates, and/or procurement of specialized equipment are the foundation of safe MR practice. Establishing an institutional MR safety program must take into consideration the conditions of the MR environment, and staff training should be tailored to its features ...

Elucidating White Matter Contributions to the Cognitive Architecture of Affective Prosody Recognition: Evidence from Right Hemisphere Stroke

Brain Sciences
Background/Objectives: Successful discourse relies not only on linguistic but also on prosodic information. Difficulty recognizing emotion conveyed through prosody (receptive affective aprosodia) following right hemisphere stroke (RHS) significantly ...

Application of MR Cytometry in Predicting Pathologic Complete Response to Neoadjuvant Chemotherapy in Breast Cancer: A Comparative Study

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background MR cytometry imaging is developed to characterize in vivo microstructures. Its clinical value in predicting pathological complete response (pCR) after neoadjuvant chemotherapy (NAC) for breast cancer remains unknown. Purpose To implement MR cytometry to predict pCR for breast cancer and compare the performance of different ...

Time-efficient combined morphologic and quantitative joint MRI: an in situ study of standardized knee cartilage defects in human cadaveric specimens

European Radiology Experimental
Background Quantitative techniques such as T2 and T1ρ mapping allow evaluating the cartilage and meniscus. We evaluated multi-interleaved X-prepared turbo-spin echo with intuitive relaxometry (MIXTURE) sequences with turbo spin-echo (TSE) contrast and ...

Australia's Three System Approach to Mammographic Image Quality Assessment

Journal of Medical Radiation Sciences, EarlyView.
Mammographic image evaluation in Australia remains constrained by the use of fragmented, subjective, and largely unevaluated systems. The continued use of the Perfect (P), Good (G), Moderate (M), Inadequate (I) (PGMI) image evaluation system (IES) framework despite concerns around its validity and reliability reflects a perceived practical utility and ...
