On-Call Radiology presents case discussions on the most common and important clinical emergencies and their corresponding imaging findings encountered on-call. Cases are divided into thoracic, gastrointestinal and genitourinary, neurological and non-traumatic spinal, paediatric, trauma, interventional and vascular imaging. Iatrogenic complications are also discussed.

With chapters from globally recognized academics, General Radiography shows the multifaceted approach to general radiography and how it enhances healthcare delivery. Potentially influential to how healthcare delivery is offered, it begins with the pertinent chapters examining image acquisition and dose optimization in diagnostic radiography. Next, chapters reflect and critically discuss aspects central to patient care, and imaging within trauma, critical care and pediatric situations. The final section of this book then explores the learning, teaching and education in the field of diagnostic radiography, with novel strategies illustrated.

Among medical imaging modalities, magnetic resonance imaging (MRI) stands out for its excellent soft-tissue contrast, anatomical detail, and high sensitivity for disease detection. However, as proven by the continuous and vast effort to develop new MRI techniques, limitations and open challenges remain. The primary source of contrast in MRI images are the various relaxation parameters associated with the nuclear magnetic resonance (NMR) phenomena upon which MRI is based. Although it is possible to quantify these relaxation parameters (qMRI) they are rarely used in the clinic, and radiological interpretation of images is primarily based upon images that are relaxation time weighted. The clinical adoption of qMRI is mainly limited by the long acquisition times required to quantify each relaxation parameter as well as questions around their accuracy and reliability. More specifically, the main limitations of qMRI methods have been the difficulty in dealing with the high inter-parameter correlations and a high sensitivity to MRI system imperfections.
Recently, new methods for rapid qMRI have been proposed. The multi-parametric models at the heart of these techniques have the main advantage of accounting for the correlations between the parameters of interest as well as system imperfections. This holistic view on the MR signal makes it possible to regress many individual parameters at once, potentially with a higher accuracy. Novel, accurate techniques promise a fast estimation of relevant MRI quantities, including but not limited to longitudinal (T1) and transverse (T2) relaxation times. Among these emerging methods, MR Fingerprinting (MRF), synthetic MR (syMRI or MAGIC), and T1-T2 Shuffling are making their way into the clinical world at a very fast pace. However, the main underlying assumptions and algorithms used are sometimes different from those found in the conventional MRI literature, and can be elusive at times. In this book, we take the opportunity to study and describe the main assumptions, theoretical background, and methods that are the basis of these emerging techniques.
Quantitative transient state imaging provides an incredible, transformative opportunity for MRI. There is huge potential to further extend the physics, in conjunction with the underlying physiology, toward a better theoretical description of the underlying models, their application, and evaluation to improve the assessment of disease and treatment efficacy.

This user-friendly second edition provides a fully up-dated and practical introduction to gynaecological ultrasound. It describes and explains background anatomy and physiology, instrumentation and how to make the best use of equipment. Emphasis is placed on how to maximise image quality, and how to recognise normal and pathological features. The volume also assesses other relevant diagnostic techniques and various management strategies, and evaluates the role of ultrasound as part of patient management.
It includes chapters on pathology of the uterus, ovaries and adnexae, paediatric and trauma cases, together with management of infertility and other gynaecological perspectives of patient management. Illustrated throughout with numerous high-quality ultrasound images and line drawings, many of them new for this latest edition, this is essential reading for practitioners in training, including radiologists, gynaecologists and sonographers.

The first complete reference dedicated to the full spectrum of women’s imaging topics
“Women’s imaging” refers to the use of imaging modalities (X-ray, ultrasound, CT scan, and MRI) available for aiding in the diagnosis and care of such female-centric diseases as cancer of the breast, uterus, and ovaries. Currently, there is no single reference source that provides adequate discussions of MRI and its important role in the diagnosis of patients with women’s health issues.
Thoroughly illustrated with the highest-quality radiographic images available, Women’s Imaging: MRI with Multimodality Correlation provides a concise overview of the topic and emphasizes practical image interpretation. It makes clear use of tables and diagrams, and offers careful examination of differential diagnosis with special notes on key learning points. Placing great emphasis on magnetic resonance imaging (MRI), while providing correlations to other important imaging modalities, the comprehensive book features the latest guidelines on imaging screening and includes in-depth chapter coverage of:
-Pelvis MRI: Introduction and Technique
-Imaging the Vagina and Urethra
-Pelvic Floor Imaging
-Imaging the Uterus
-Imaging the Adnexa
-Imaging Maternal Conditions in Pregnancy
-Fetal Imaging
-Breast MRI: Introduction and Technique
-ACR Breast MRI Lexicon and Interpretation
-Preoperative Breast Cancer Evaluation and Advanced Breast Cancer Imaging
-Postsurgical Breast and Implant Imaging
-MR-Guided Breast Interventions
Providing up-to-date information on many of the health issues that affect women across the globe, Women’s Imaging will appeal to all general radiologists – especially those specializing in body imaging, breast imaging, and women’s imaging – as well as gynaecologists and obstetricians, breast surgeons, oncologists, radiation oncologists, and MRI technologists.

Imaging is a critical component in the delivery of radiotherapy to patients with malignancy, and this book teaches the principles and practice of imaging specific to radiotherapy. Introductory chapters outline the basic principles of the available imaging modalities including x-rays, ultrasound, CT, MR, nuclear medicine, and PET. Site specific chapters then cover the main tumor sites, reviewing optimal imaging techniques for diagnosis, staging, radiotherapy planning, and follow-up for each site. Chapters are co-authored by oncologists and radiologists specializing in a specific area to provide an authoritative view on the role of imaging in the patient’s journey and examples of relevant images are provided throughout. The important areas of radiation protection, exposure justification, and risks, are also comprehensively covered, exploring issues such as balancing radiation exposure with long-term risks of radiation effects, such as second cancer induction.
