Radiology 101 The Basics And Fundamentals Of Imaging Pdf [UPD] Free Download

These are the fundamental image capture basics for radiology technologists to help achieve high-quality, consistent imaging. Radiographers who understand and routinely apply these principles are vital to the success of any imaging facility.

Modern imaging equipment has revolutionized the industry by performing many of these functions automatically, but radiographers must understand these principles, and adjust or override the features to ensure correct operation and reduce unnecessary exposure to patients. Getting back to the basics can save time and aggravation by reducing repeat images. It can save money, and most importantly, it will contribute to improved patient care.

Mark Mullins, MD, PhD, vice chair for education and professor in the Department of Radiology and Imaging Sciences, Emory University School of Medicine, Atlanta, said he always keeps in mind that the radiology basics never really change and remain the most important of radiological training and education.

Along with basic radiology fundamentals, Manisha Bahl, MD, MPH, associate professor of radiology at Harvard Medical School and Massachusetts General Hospital in Boston, believes a foundational AI education is also important.

NIIC-RAD, which offers imaging informatics education to trainees and practicing radiologists around the world, covers fundamentals like clinical workflow and patient centric radiology and other topics, such as data science, mission learning and 3D printing.

Although not technically radiographic techniques due to not using X-rays, imaging modalities such as PET and MRI are sometimes grouped in radiography because the radiology department of hospitals handle all forms of imaging. Treatment using radiation is known as radiotherapy.

In response to increased concern by the public over radiation doses and the ongoing progress of best practices, The Alliance for Radiation Safety in Pediatric Imaging was formed within the Society for Pediatric Radiology. In concert with the American Society of Radiologic Technologists, the American College of Radiology, and the American Association of Physicists in Medicine, the Society for Pediatric Radiology developed and launched the Image Gently campaign which is designed to maintain high quality imaging studies while using the lowest doses and best radiation safety practices available on pediatric patients.[10] This initiative has been endorsed and applied by a growing list of various professional medical organizations around the world and has received support and assistance from companies that manufacture equipment used in radiology.

X-rays were put to diagnostic use very early; for example, Alan Archibald Campbell-Swinton opened a radiographic laboratory in the United Kingdom in 1896, before the dangers of ionizing radiation were discovered. Indeed, Marie Curie pushed for radiography to be used to treat wounded soldiers in World War I. Initially, many kinds of staff conducted radiography in hospitals, including physicists, photographers, physicians, nurses, and engineers. The medical speciality of radiology grew up over many years around the new technology. When new diagnostic tests were developed, it was natural for the radiographers to be trained in and to adopt this new technology. Radiographers now perform fluoroscopy, computed tomography, mammography, ultrasound, nuclear medicine and magnetic resonance imaging as well. Although a nonspecialist dictionary might define radiography quite narrowly as "taking X-ray images", this has long been only part of the work of "X-ray departments", radiographers, and radiologists. Initially, radiographs were known as roentgenograms,[31] while skiagrapher (from the Ancient Greek words for "shadow" and "writer") was used until about 1918 to mean radiographer. The Japanese term for the radiograph, rentogen (), shares its etymology with the original English term.

Most of GI radiology is covered in the fundamental and body imaging books. Mayo Clinic Gastrointestinal Imaging Review and Introduction to Fluoroscopy: For Residents & Professionals Alike are good books for fluoroscopy which is not covered well in these books.

Although radiology is not one of the major subjects in medical school, it is increasingly being integrated into everyday clinical practice and hence it is imperative for medical students to be cognizant with the basics of radiology. Also after the introduction of the NEET entrance exam, radiology has assumed more importance in the entrance exams. These are a few books that medical students can read for learning the basics of radiology and help them with these exams as well.

The fifth edition is thoroughly updated and includes new or expanded chapters on nuclear medicine, pediatric radiology, and emerging imaging techniques. A comprehensive question bank, which functions as a valuable self-assessment tool, concludes the book.

The objective of this elective is to offer the student an opportunity to observe how radiology contributes to patient care. It is hoped that the student will acquire an appreciation for the various imaging modalities and their application to the evaluation of abdominal disease.

Radiography: A Review of the Basics is intended to provide the radiographer with a refresher of radiographic core theory and fundamentals of radiographic anatomy and positioning. The course is based on the 4th edition textbook, Limited Radiography (2016) authored by Jeana Fleitz & Frances E. Campeau. The first four chapters include information about the occupation, ethical and legal aspects of healthcare, and patient care. Chapters 5-13 provide a review of radiographic core theory and imaging equipment. Chapters 14-19 cover radiographic anatomy & positioning of the chest and abdomen, upper and lower extremity, spine, skull facial bones, and paranasal sinuses. The last chapter provides an overview of current imaging modalities such as bone densitometry, ultrasound, magnetic resonance image, and computed tomography.

A tremendous interest in deep learning has emerged in recent years [1]. The most established algorithm among various deep learning models is convolutional neural network (CNN), a class of artificial neural networks that has been a dominant method in computer vision tasks since the astonishing results were shared on the object recognition competition known as the ImageNet Large Scale Visual Recognition Competition (ILSVRC) in 2012 [2, 3]. Medical research is no exception, as CNN has achieved expert-level performances in various fields. Gulshan et al. [4], Esteva et al. [5], and Ehteshami Bejnordi et al. [6] demonstrated the potential of deep learning for diabetic retinopathy screening, skin lesion classification, and lymph node metastasis detection, respectively. Needless to say, there has been a surge of interest in the potential of CNN among radiology researchers, and several studies have already been published in areas such as lesion detection [7], classification [8], segmentation [9], image reconstruction [10, 11], and natural language processing [12]. Familiarity with this state-of-the-art methodology would help not only researchers who apply CNN to their tasks in radiology and medical imaging, but also clinical radiologists, as deep learning may influence their practice in the near future. This article focuses on the basic concepts of CNN and their application to various radiology tasks, and discusses its challenges and future directions. Other deep learning models, such as recurrent neural networks for sequence models, are beyond the scope of this article.

An abundance of well-labeled data in medical imaging is desirable but rarely available due to the cost and necessary workload of radiology experts. There are a couple of techniques available to train a model efficiently on a smaller dataset: data augmentation and transfer learning. As data augmentation was briefly covered in the previous section, this section focuses on transfer learning.

Because 2D images are frequently utilized in computer vision, deep learning networks developed for the 2D images (2D-CNN) are not directly applied to 3D images obtained in radiology [thin-slice CT or 3D-magnetic resonance imaging (MRI) images]. To apply deep learning to 3D radiological images, different approaches such as custom architectures are used. For example, Setio et al. [39] used a multistream CNN to classify nodule candidates of chest CT images between nodules or non-nodules in the databases of the Lung Image Database Consortium and Image Database Resource Initiative (LIDC-IDRI) [40], ANODE09 [41], and the Danish Lung Cancer Screening Trial [42]. They extracted differently oriented 2D image patches based on multiplanar reconstruction from one nodule candidate (one or nine patches per candidate), and these patches were used in separate streams and merged in the fully connected layers to obtain the final classification output. One previous study used 3D-CNN for fully capturing the spatial 3D context information of lung nodules [43]. Their 3D-CNN performed binary classification (benign or malignant nodules) and ternary classification (benign lung nodule, and malignant primary and secondary lung cancers) using the LIDC-IDRI database. They used a multiview strategy in 3D-CNN, whose inputs were obtained by cropping three 3D patches of a lung nodule in different sizes and then resizing them into the same size. They also used the 3D Inception model in their 3D-CNN, where the network path was divided into multiple branches with different convolution and pooling operators.
