This book is a basic, practical guide to performing and interpreting state-of-the-art prostate MRI, utilizing the latest guidelines in the field. Prostate MRI has become one of the fastest growing examinations in the radiology practice, and this demand has continuously increased within the past decade. Since it is relatively new, MRI of the prostate is predominantly being performed at academic institutions, however there is a growing demand within the lower-tier health care institutions to offer this examination to their patients. This is an ideal guide for radiologists who want to enhance or initiate prostate MRI service for their referring clinicians and as a manual for technologists and those who are in training. Prostate cancer is the second leading cause of cancer death in men, exceeded only by lung cancer. The best predictor of disease outcome lies with correct diagnosis, which requires precise imaging and diagnostic procedures aided by prostate MRI. Urologists, medical oncologists and radiation oncologists all agree that multi-parametric prostate MRI is essential for evaluation of prostate cancer. However, the technical aspects of prostate MR imaging are not as straightforward as for the other imaging modalities and constantly evolving. Its small size presents a real challenge to the radiologist, who needs to do the T2 and diffusion weighted images and perform a dynamic contrast enhanced sequence correctly. These images may also need to be analyzed on an independent workstation. Due to the absence of a current reference manual, when a radiologist wants to establish a prostate imaging service, he/she needs to attend dedicated prostate MR workshops or dive into the literature search alone, only to get more confused about what to do and how to do it.With this book, expert authors were asked to give clear guidance to those who want to enhance or initiate their prostate imaging service. With this much-needed, concise, practical guidance, radiologists can perform and interpret multi-parametric prostate MRI in a standardized fashion, in concordance with PI-RADS v2.1 that can be applicable to all available hardware platforms (GE, Philips, Siemens, Toshiba). Additionally, they can perform post-processing for possible targeted biopsy and interpret post-therapy and PET studies. The book discusses imaging protocols (planning and prescription) and sequence parameters with representative images for each MRI sequence. This handbook-style practical manual can be used in the radiology reading room by those interpreting the MR exam as a reference as well as at the MRI scanner by the technologists as a guide. Coverage of basic prostate anatomy, pathology, Urologists¿ point of view, MRI guided radiation treatment planning and molecular imaging is also included. Throughout the book, authors will discuss basics, pitfalls, and provide tips in image acquisition and interpretation, alongside several case examples.

This open access book presents a wide portfolio of examples of positron emission tomography coupled with computer tomography (PET/CT) studies in various cardiac conditions in order to provide a rationale for the implementation of this technology in an array of clinical conditions.Cardiovascular diseases are a major contributor to premature morbidity and mortality worldwide. Low- and middle-income countries (LMICs) are particularly affected by cardiovascular diseases (CVDs), with more than 75% of all CVDs deaths occurring in these countries. For this reason, target 3.4 of the United Nations (UN) Sustainable Development Goals (SDGs) agenda aims at a 30% reduction in premature mortality due to non-communicable diseases (NCDs), which include CVDs, by 2030.Among CVDs, ischemic heart disease (IHD) plays an important role and, according to the Institute for Health Metrics and Evaluation (IHME), it was responsible for 15.96% of global deaths in 2017. Between 2000 and 2017, the number of IHD deaths worldwide increased by 0.26% per year.Several imaging tools help to non-invasively diagnose, stratify risk and guide management in cardiac disease. They include nuclear cardiology techniques, using either SPECT (single photon emission computed tomography) or PET/CT. While myocardial imaging with SPECT has been fully embraced by the cardiology community and is widely available worldwide, PET/CT introduction has been slower, due not only to its higher costs, but also to the limited availability of PET/VCT scanners, mostly utilized for oncological applications.This book is an invaluable tool for nuclear medicine physicians, cardiologists and radiologists.

Where do you begin to look for a recent, authoritative article on the diagnosis or management of a particular malignancy? The few general oncology textbooks are generally out of date. Single papers in specialized journals are informative but seldom comprehensive; these are more often preliminary reports on a very limited number of patients. Certain general journals frequently publish good in-depth reviews of cancer topics, and published symposium lectures are often the best overviews available. Unfor­ tunately, these reviews and supplements appear sporadically, and the reader can never be sure when a topic of special interest will be covered. Cancer Treatment and Research is a series of authoritative volumes that aim to meet this need. It is an attempt to establish a critical mass of oncology literature covering virtually all oncology topics, revised frequently to keep the coverage up to date, easily available on a single library shelf or by a single personal subscription. We have approached the problem in the following fashion: first, by dividing the oncology literature into specific subdivisions such as lung can­ cer, genitourinary cancer, and pediatric oncology; second, by asking emi­ nent authorities in each of these areas to edit a volume on the specific topic on an annual or biannual basis. Each topic and tumor type is covered in a volume appearing frequently and predictably, discussing current diagnosis, staging, markers, all forms of treatment modalities, basic biology, and more.

Cancers of the head and neck are among the most morbid of cancers. Convention­ al surgery and/or radiation therapy have a high cure rate for patients with early stage disease. However, despite optimal treatment with surgery and radiotherapy, patients with nodal spread or extensive local disease have a low cure rate. Even if a cancer is cured, a patient is often left with long-term debilities from the treatment and/or cancer. The major causes for decreased survival in patients with advanced head and neck cancer include local recurrence, distant metastases, and second primaries. All of these need to be addressed if one is to improve upon the curability of advanced disease. There are several new techniques, surgical and radiotherapeutic, designed to improve local control. Brachytherapy, or interstitial implantation, delivers a high dose of localized radiation with minimal normal tissue injury. This technique as discussed by Goffinet, may be even more efficacious when combined with hyperthermia. New, creative methods of radiation therapy delivery, such as the use of multiple fractions per day, as discussed by Parsons and Million, are also contributing to long-term local control. Laser therapy, discussed by Ossoff and Nemeroff, provides another tool for treatment of local disease.

Since the introduction of myocardial perfusion imaging and radionuclide angiography in the mid-seventies, cardiovascular nuclear medicine has undergone an explosive growth. The use of nuclear cardiology techniques has become one of the cornerstones of the noninvasive assessment of coronary artery disease. In the past 15 years major steps have been made from visual analysis to quantitative analysis, from planar imaging to tomographic imaging, from detection of disease to prognosis, and from separate evaluations of perfusion, metabolism, and function to an integrated assessment of myocardial viability. In recent years many more advances have been made in cardiovascular nuclear imaging, such as the development of new imaging agents, reevaluation of existing procedures, and new clinical applications. This book describes the most recent developments in nuclear cardiology and also addresses new contrast agents in MRI. What's New in Cardiac Imaging will assist the clinical cardiologist, the cardiology fellow, the nuclear medicine physician, and the radiologist in understanding the most recent achievements in clinical cardiovascular nuclear imaging.

Distance measurements in biological systems by EPR The foundation for understanding function and dynamics of biological systems is knowledge of their structure. Many experimental methodologies are used for determination of structure, each with special utility. Volumes in this series on Biological Magnetic Resonance emphasize the methods that involve magnetic resonance. This volume seeks to provide a critical evaluation of EPR methods for determining the distances between two unpaired electrons. The editors invited the authors to make this a very practical book, with specific numerical examples of how experimental data is worked up to produce a distance estimate, and realistic assessments of uncertainties and of the range of applicability, along with examples of the power of the technique to answer biological problems. The first chapter is an overview, by two of the editors, of EPR methods to determine distances, with a focus on the range of applicability. The next chapter, also by the Batons, reviews what is known about electron spin relaxation times that are needed in estimating distances between spins or in selecting appropriate temperatures for particular experiments. Albert Beth and Eric Hustedt describe the information about spin-spin interaction that one can obtain by simulating CW EPR line shapes of nitroxyl radicals. The information in fluid solution CW EPR spectra of dual-spin labeled proteins is illustrated by Hassane Mchaourab and Eduardo Perozo.
