  • The Transition to Peer Learning by C. G. Roth, H. V. Naringrekar, and A. E. Flanders

    The Transition to Peer Learning

    C. G. Roth, H. V. Naringrekar, and A. E. Flanders

    Problem Description: Historically, peer review has been compelled by regulatory and legislative mandates, such as the Joint Commission Ongoing Professional Practice Evaluation (OPPE) requirement and the Health Care Quality Improvement Act (HCQIA) enacted by Congress in 1986. [1] However, these external mandates were focused on quality assurance, generally carrying punitive connotations and practically translated into rote compliance without the benefit of learning and improvement. In fact, the lack of quality improvement focus prompted the Institute of Medicine (IOM) to release its 2015 report, “Improving Diagnosis in Health Care,” stating that a “critical type of error in health care—diagnostic error—has received relatively little attention.” [2] The IOM report alarmingly reports that 5% of the US population experience diagnostic error annually, most experience diagnostic error in the course of a lifetime and diagnostic error contributes to 10% patient deaths and 6-17% of adverse events in hospitals. The IOM report framed a number of recommendations that potentially informs peer review and learning activities more broadly (Figure 1).

  • DTI Metrics for Multi-site/Multi-scanner Study of Adult Cervical Spinal Cord by Devon M. Middleton, PhD; Joshua Fisher, BS; Adam E. Flanders, MD; Feroze Mohamed, PhD; John H. Wu, MD; Laura Krisa, PhD; Mark Elliot, PhD; Scott H. Faro, MD; and Jessica Evans, BS

    DTI Metrics for Multi-site/Multi-scanner Study of Adult Cervical Spinal Cord

    Devon M. Middleton, PhD; Joshua Fisher, BS; Adam E. Flanders, MD; Feroze Mohamed, PhD; John H. Wu, MD; Laura Krisa, PhD; Mark Elliot, PhD; Scott H. Faro, MD; and Jessica Evans, BS

    Background and Objective

    A major variable in DTI spinal cord studies is the diversity in MRI scanner vendor and field strength. While there are several techniques proven to acquire DTI data, there are no standardized accepted methods for acquisition and processing. As more medical systems are utilizing this technology to evaluate the spinal cord, it is important to study the reproducibility of the DTI metrics among various scanner platforms, coil configurations and software implementations to determine the variance in obtaining normative spinal cord DTI data. This preliminary data for a multi-site DTI study examines the effects of these different MR vendors and field strengths on the DTI values of the adult cervical spinal cord.

  • “Step & Shoot” Cardiac Gated CT for Detection of Pulmonary Embolism: Technique and Advantages by Dinesh K. Sharma, MD

    “Step & Shoot” Cardiac Gated CT for Detection of Pulmonary Embolism: Technique and Advantages

    Dinesh K. Sharma, MD

    Introduction

    Pulmonary Embolism (PE) is a common condition with significant morbidity and mortality. Prompt recognition, diagnosis and management is important, as untreated PE complications are high; also treatment with long term anticoagulation has serious complications.

  • Conversion of Intermediate LIRADS Categories to Hepatocellular Carcinoma in patients with Chronic Hepatitis B: Korean Immigrant Experience by Kofi-Buaku Atsina, MD; Zhenteng Li, MD; and Sandeep Deshmukh, MD

    Conversion of Intermediate LIRADS Categories to Hepatocellular Carcinoma in patients with Chronic Hepatitis B: Korean Immigrant Experience

    Kofi-Buaku Atsina, MD; Zhenteng Li, MD; and Sandeep Deshmukh, MD

    Introduction and Objective

    The Liver Imaging Reporting and Data System (LIRADS) was created to standardize the reporting and data collection of MR imaging for hepatocellular carcinoma (HCC) in high risk patients. The major categories for LIRADS have the following descriptors:

    LI-RADS 1 = Definitely benign

    LI-RADS 2 = Probably benign

    LI-RADS 3 = Intermediate probability for HCC

    LI-RADS 4 = Probably HCC

    LI-RADS 5 = Definitely HCC

    LI-RADS 5V = Definitely HCC with tumor in vein

    LI-RADS M = Probable malignancy, not specific for HCC

    LI-RADS T = Treated Observation

    However, there is a paucity of quantitative evidence for the progression of LIRADS 2, 3 and 4, (hereafter defined as intermediate LIRADS categories) to LIRADS 5. Our objective was to investigate the conversion of intermediate LIRADS categories to definite hepatocellular carcinoma (LIRADS 5) to help inform management decisions regarding treatment and better stratify imaging follow up for high-risk patients with intermediate LIRADS categories.

  • Development of a Temperature Sensitive Face Mask for Identification and Triage of Febrile Patients by Annemarie Daecher, Flemming Forsberg, and John R. Eisenbrey

    Development of a Temperature Sensitive Face Mask for Identification and Triage of Febrile Patients

    Annemarie Daecher, Flemming Forsberg, and John R. Eisenbrey

    Abstract:

    Many infectious diseases are most transmittable when the carrier is presenting with fever. We propose a disposable face mask that changes color as an indicator of fever to provide hospitals with a quick and inexpensive method for triaging infected patients while limiting exposure to others. Two blue thermochromatic dyes which transition to white at 89°F and 92°F were mixed with white paint and applied to 5 types of disposable face masks. During trials, a wearer either sat at rest or ran on a treadmill for 20 minutes and images were obtained every 5 minutes with a thermal camera to record surface body temperature. At rest there was no change in body temperature or in mask color. After 20 minutes of running, a 5°F increase in surface body temperature was measured. Only the mask created with the 89°F dye showed a color transition with large white areas apparent post-run. This indicates the ability of thermochromatic masks to measure body temperature and potentially identify febrile patients.

  • Pulse Shaping for Improved Diagnosis of Portal Hypertension Using Subharmonic Aided Pressure Estimation by Ipshita Gupta, John R. Eisenbrey, Maria Stanczak, Anush Sridharan, Jaydev K. Dave, Ji-Bin Liu, Christopher Hazard, Colette Shaw, Susan Shamini-Noori, Jonathan M. Fenkel, Michael Soluen, Chandra Sehgal, Kirk Wallace, and Flemming Forsberg

    Pulse Shaping for Improved Diagnosis of Portal Hypertension Using Subharmonic Aided Pressure Estimation

    Ipshita Gupta, John R. Eisenbrey, Maria Stanczak, Anush Sridharan, Jaydev K. Dave, Ji-Bin Liu, Christopher Hazard, Colette Shaw, Susan Shamini-Noori, Jonathan M. Fenkel, Michael Soluen, Chandra Sehgal, Kirk Wallace, and Flemming Forsberg

    Subharmonic aided pressure estimation (SHAPE) is based on the inverse relationship between the subharmonic amplitude of contrast microbubbles (obtained by transmitting at the fundamental frequency fo and receiving at fo/2) and the ambient pressure (see fig.1).

    A noninvasive ultrasound based pressure estimation procedure would be a major development in the diagnosis of portal hypertension and less invasive than the current catheter-based hepatic venous pressure gradient (HVPG) measurement.

    The hypothesis of this study was that portal vein pressures can be monitored and quantified noninvasively in humans using SHAPE.

    First selected waveforms were optimized in vitro and in canines, then SHAPE was correlated with measured HVPG in patients undergoing a transjugular liver biopsy (TJLB).

  • Four-Dimensional (4D) Subharmonic Aided Pressure Estimation for Monitoring Neoadjuvant Chemotherapy Response of Breast Cancer by Kibo Nam, Maria Stanczak, Anush Sridharan, Adam C. Berger, Tiffany Avery, John R. Eisenbrey, and Flemming Forsberg

    Four-Dimensional (4D) Subharmonic Aided Pressure Estimation for Monitoring Neoadjuvant Chemotherapy Response of Breast Cancer

    Kibo Nam, Maria Stanczak, Anush Sridharan, Adam C. Berger, Tiffany Avery, John R. Eisenbrey, and Flemming Forsberg

    Introduction

    Neoadjuvant chemotherapy is a well-established treatment option for patients with non-metastatic breast cancer. The patient response is correlated with survival. However, the optimal method for monitoring neoadjuvant therapy response has not been established. One factor that may affect the response of neoadjuvant therapy is the interstitial fluid pressure (IFP). Increased IFP prevents an effective delivery of therapeutic agents and reduces the efficacy of the therapy. Recently, subharmonic-aided pressure estimation (SHAPE) using contrast-enhanced ultrasound (CEUS) has been developed and its potential was demonstrated in animals as a non-invasive technique for IFP measurements. The SHAPE method estimates IFP based on the inverse relationship between the subharmonic signal magnitude from CEUS and IFP. The purpose of this study was to determine if 4D SHAPE can predict the response of breast cancer to neoadjuvant chemotherapy.
