  • The first edition of Handbook of MRI Technique was a resounding success. The rapidly increasing number of radiographers and technologists entering the modality, coupled with the development of education and training courses worldwide, has resulted in an increased demand for MRI books of any shape and size. The education of radiographers, technologists and radiologists often lags behind the rapid technological advances in MR.

  • MRI at a Glance is one of a series of books that presents complex information on medical subjects in an easily accessible format. The aim is to have all information on a particular topic summarized on two facing pages of the book so that the reader has essential points at their fingertips. When the publishers approached me about including MRI in this format, I was rather sceptical.

  • The practicing radiologist is continually challenged to update his/her competencies so as to deliver state-of-the-art radiological care. Nowhere is this truer than in the rapidly evolving world of magnetic resonance imaging, where innovations in both technology and diagnostic pharmaceuticals have dramatically altered the landscape of practice.

  • The study of the heart and vessels by Magnetic Resonance Imaging represents a relatively new field of application, especially if one considers the large-scale diagnostic use of the technique in the neurological and muscular fields. The explanation of the delayed application in the cardiovascular field can be sought in the methodological complexity linked to the study of moving anatomical structures.

  • Since its first implementation by Lauterbur [1], Magnetic Resonance Imaging (MRI) has become an important noninvasive imaging modality. MRI has found a number of applications in the fields of biology, engineering, and material science. Because it provides unique contrast between soft tissues (which is generally superior to that of CT) and high spatial resolution, MRI has revolutionized diagnostic imaging in medical science. An important advantage of diagnostic MRI as compared to CT is that the former does not use ionizing radiation....

  • The field of medical imaging is advancing at a rapid pace. Imaging modalities like x-ray radiography, x-ray computed tomography (CT), ultrasound, nuclear imaging, magnetic resonance imaging (MRI), and optical imaging have been used in biology and medicine to visualize anatomical structures as large as the lung and liver and as small as molecules. Ultrasound is considered the most cost-effective among them. It is used routinely in hospitals and clinics for diagnosing a variety of diseases.

  • The goals of experimental neuroscience research are fundamentally to gain mechanistic understanding of the pathology of disease in order to identify appropriate targets for potential pharmacological intervention and evaluation of putative therapies. With the advances in gene manipulation and transgene technologies, we have unprecedented ability to generate animal models of disease that more closely mimic the clinical conditions. Noninvasive techniques capable of investigating altered pathophysiologies are now of paramount importance.

  • Computed tomography (CT) is the mainstay of cancer imaging outside of the central nervous system. Advances in multidetector CT (MDCT) technology have had a profound impact on its diagnostic capabilities. Such techniques as multiphase, single breath-hold imaging, CT angiography (CTA), volume rendering and virtual colonography owe their success to the development of multidetector arrays with continuously moving gantries.

  • Soft tissues and exudates are best evaluated using contrast medium, therefore the best imaging technique is contrast CT-scan. The soft tissues, spaces and exudates appear radioopaque on contrast CT scans. Moreover, CT scan is cheaper, readily available and has no electromagnetic effects on patients with metallic implants compared to MRI and most patients do not react to the contrast medium (Gadolinium) which is injected into the body via intravenous route before the scan.

  • Neoplasms (See also Chap. 374) Back pain is the most common neurologic symptom in patients with systemic cancer and may be the presenting symptom. The cause is usually vertebral metastases. Metastatic carcinoma (breast, lung, prostate, thyroid, kidney, gastrointestinal tract), multiple myeloma, and non-Hodgkin's and Hodgkin's lymphomas frequently involve the spine. Cancer-related back pain tends to be constant, dull, unrelieved by rest, and worse at night. By contrast, mechanical low back pain usually improves with rest.

  • Velocity encoded phase-contrast magnetic resonance imaging (VE-PC MRI) is another imaging technique used to noninvasively measure Achilles tendon strain and changes in its force-displacement relationship concomitant with chronic unloading and subsequent recuperation. This technique will be reviewed in terms of its ability to quantify the Achilles tendon Young’s modulus (MPa) from a stress-strain curve.

  • Angiography or arteriography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins and the heart chambers. This is traditionally done by injecting a radio-opaque contrast agent into the blood vessel and imaging using X-ray based techniques such as fluoroscopy. So angiography consists of MRI, CT-Scan. . .
