To determine whether adding shear-wave (SW) elastographic features could improve accuracy of ultrasonographic (US) assessment of breast masses . , 958 women consented to repeat standard breast US supplemented by quantitative SW elastographic examination in this prospective multicenter institutional review board-approved, HIPAA-compliant protocol. B-mode Breast Imaging Reporting and Data System (BI-RADS) features and assessments were recorded. SW elastographic evaluation (mean, maximum, and minimum elasticity of stiffest portion of mass and surrounding tissue; lesion-tofat elasticity ratio; ratio of SW elastographic-to-B-mode lesion diameter or area; SW elastographic lesion shape and homogeneity) was performed. Qualitative color SW elastographic stiffness was assessed independently. Nine hundred thirty-nine masses were analyzable; 102 BI-RADS category 2 masses were assumed to be benign; reference standard was available for 837 category 3 or higher lesions. Considering BI-RADS category 4a or higher as test positive for malignancy, effect of SW elastographic features on area under the receiver operating characteristic curve (AUC), sensitivity, and specifi city after reclassifying category 3 and 4a masses was determined.
**Medical department, HRPZ II, Kota Bharu, Malaysia Agnostic Pathology is a new term trying to emerge to mean a merger of radiology, pathology and molecular diagnostic information. Radiology imaging and histopathology are two different investigatory modalities in clinical diagnosis. They appear totally disconnected and isolated without any link as their departments, organization, function and their modus operandi are totally different. Both stand firmly on their own podium to exercise their sincere efforts to analyze their investigations; their results are very much mandatory in ‘accurate final diagnosis and proper management plan’ of all patients. Even though currently both have segregated functioning, yet there is widely growing opinion that this sort of isolation of radiology and pathology should end and a unique assimilation is greatly required to make an accurate diagnosis which helps infinitely in the betterment of human care. Thereby the quality and outcomes of patient management will improve markedly. During the early 1950s, due to lack of modern facilities, diagnostic decisions were taken by the treating doctor on the merit of his own intelligence. Some experienced clinicians having an extensive updated knowledge in the field could make vital split-second decisions basing only on clinical features and plan their treatment. A patient with acute abdomen with rigidity and rebound tenderness would be taken straight to the operation theater; biopsies were done from any suspected organ by the treating doctor from the site which he felt the lesion was. This was an acceptable practice at that time. This subconscious decision-making process when used every day for complex problems carried high possibility of fatal errors in many patients. Radiology was encompassing only a few modalities; basically plain x-rays and contrast studies such as IVU and Barium studies; venography, lymphangiography and angiography were infrequently performed. Cross-sectional imaging (Ultrasound, CT and MRI) was not available. Therefore pathological changes within the organs were scarcely made obvious. Assessment of anatomical planes was not certain. Things have undergone enormous changes later. Scientific approach and evidence based medicine became a necessity. Recent molecular diagnostic techniques, cross-sectional 3-4 D digital imaging, quantitative image analysis, fMRI and PET scans help to improve early detection and characterization of diseases, and predictive, diagnostic and prognostic performance across a spectrum of diseases. We can exactly identify the plane of a pathological lesion. We can reach a correct diagnosis akin to that of histopathology examination (HPE).
How to Think Like a Radiologist
2008
Radiologic investigations can be confusing to clinicians and radiologists alike. Questions invariably arise as to which type of imaging study best answers the clinical question posed. Once a modality is determined, decisions must be made regarding the technical manner in which the study is performed and if intravenous contrast is required. Patient factors, risks, benefits, and other variables must also be considered. This pocket guide is written for anyone who needs to understand enough about radiology to know which study to order in a patient workup. The book addresses imaging studies by modality, body region, and type of study in bulleted outline format for easy reference. General considerations for each modality – including advantages and disadvantages – are presented, followed by patient preparation and requirements for each type of examination. The author explains how specific studies are performed and what information can be obtained, study indications, contraindications, and ...
Fundamentals of Clinical Research for Radiologists
2005
This is the 12th in the series designed by the American College of Radiology (ACR), the Canadian Association of Radiologists, and the American Journal of Roentgenology. The series, which will ultimately comprise 22 articles, is designed to progressively educate radiologists in the methodologies of rigorous clinical research, from the most basic principles to a level of considerable sophistication. The articles are intended to complement interactive software that permits the user to work with what he or she has learned, which is available on the ACR Web site (www.acr.org).
Evidence-based radiology for diagnostic imaging: What it is and how to practice it
Evidence-based radiology is defined as the decision that results from integrating clinical information to select the most appropriate imaging test on the basis of the best available evidence, the physician's experience, and the patient's expectations. The practice of evidence-based radiology consists of five steps: formulating the question, performing an efficient search of the literature, critically evaluating the literature, applying the results of the search and evaluation while taking into account our experience and the patient's values, and evaluating the results obtained within our own practice. In diagnostic imaging, the number of resources available for evidence-based radiology is increasing: apart from books, articles, and web pages on this subject, evidence-based radiology is receiving more attention at diagnostic imaging conferences. The principles of evidence-based radiology will help promote the appropriate use of resources, greatly benefiting patients (decreasing the use of examinations that use ionizing radiation), professionals (less overload), and managers (more efficient use of resources). Radiología basada en la evidencia en el diagnóstico por imagen: ¿qué es y cómo se practica? Resumen La Radiología Basada en la Evidencia (RBE), se define como la decisión que resulta de integrar la clínica con la prueba de imagen más adecuada en base a la mejor evidencia disponible, la experiencia del médico y las expectativas del paciente. Su práctica consta de cinco pasos: formular la pregunta, realizar una búsqueda eficiente de la literatura, evaluar críticamente la literatura, aplicarla a los resultados teniendo en cuenta nuestra experiencia y los valores del paciente y evaluar los resultados obtenidos dentro de nuestra práctica. En Radiodiagnóstico se está incrementando el número de recursos disponibles de RBE, encontrando actualmente libros, artículos, páginas web, así como potenciando actividades en congresos de nuestra especialidad. Los principios de la RBE ayudarán a promover el uso apropiado de los recursos, aportando enormes beneficios a pacientes (disminuye el uso de las exploraciones que utilizan radiaciones ionizantes), profesionales (menos sobrecarga) y gestores (uso más eficiente de recursos).

This book is a collaborative effort with medical students from the Rutgers/Robert Wood Johnson Medical School, previously Robert Wood Johnson Medical School. The students contributed chapters written as honors papers,while on their Interventional Radiology elective. This publication is not meant to completely cover the ever expanding realm of interventional radiology but includes topics of interest to the students while on their elective. It has been rewarding to work with these amazing students, many of whom have elected to practice diagnostic and interventional radiology. This work was supported by a small grant from the Rutgers Library to create affordable books. As it is self published please overlook minor flaws.The newest area of interventional radiology, interventional oncology, will be covered in subsequent chapters as they are written. As with other dynamic fields of medicine some material becomes outdated soon after it is written. As this is an electronic publication we wi...
