Available in PDF, EPUB and Kindle. Book excerpt: La mise à disposition des agents de contraste ultrasonores a introduit une nouvelle dimension dans l’examen échographique avec la possibilité d’une exploration en temps réel de la cinétique de prise de contraste de lésions variées. Les indications potentielles de ces microbulles touchent la quasi-totalité des organes profonds et superficiels, mais également les possibilités d’études pharmacologiques pour la néo-angiogenèse ou le guidage thérapeutique par méthodes physiques. Enfin de nouvelles applications se font jour dans le domaine des produits ciblés et le transport de principes actifs. Il nous est apparu opportun de tenter de faire le point sur ce monde en mouvement au travers d’une collaboration intense entre les diverses équipes impliquées et reconnues dans ce domaine et dont malheureusement, seulement certaines sont ici représentées. Nous souhaitons que cet ouvrage soit un point de référence actuel de l’échographie de contraste, point qui demandera certainement à évoluer dans les prochaines années. Il démontre avec force que les ultrasons peuvent jouer un rôle très important dans l’imagerie moderne tant diagnostique que thérapeutique en raison de leur performance diagnostique mais également de leur caractère non invasif. Nous espérons que vous prendrez autant de plaisir à y rechercher l’information utile que nous en avons eu à découvrir une imagerie fonctionnelle ultrasonore en temps réel et écrire ces différents chapitres.

This book was released on 2009 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this work was to study the potential for contrast-enhanced functional ultrasound imaging (Cefui) to assess the abdominal microcirculation, according to three major axes of research: 1) The first axis consisted in proposing and validating a new method improving non invasive contrast-enhanced renal blood flow measurements, using the mean signal intensity in a feeding artery in order to normalize contrast-enhanced renal blood flow estimation. However, while these ex vivo results suggest that this technique has great potentials, other parameters, mainly ultrasound beam attenuation, must be taken into account to obtain reproducible measurements. 2) The second axis consisted in evaluating qualitative abdominal Cefui for tumoral detection. For the detection of liver metastases from carcinoid tumor, the first study reports sensitivity values for contrast-enhanced ultrasound similar to those obtained with enhanced computed tomography. The second study demonstrates that Cefui provides high specificity and predictive values for the early detection of residual tumor after radiofrequency ablation of renal tumors even though its sensitivity remains lower than that of contrast-enhanced CT. 3) The third axis deals with added diagnostic value in terms of characterization of renal tumors of quantitative assessment of tumor perfusion compared to that of qualitative analysis. Abdominal Cefui has unique advantages including low cost, availability, absence of renal toxicity and radiation, and excellent temporal resolution. However, it still requires improvements and standardization to be reproducible and be transferred to the clinical setting. It may somehow yield quantitative information with respect to abdominal organs microcirculation. Further studies correlating Cefui results with those of other functional imaging methods are needed

Download or read book Duplex Sonography written by Edward G. Grant and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Duplex Sonography is the first comprehensive text written about this modality. The book offers the reader detailed information about all major uses of duplex and is introduced by a brief chapter on the physical principles of doppler ultrasound as it relates to duplex scanning. Duplex Sonography is intended to provide relevant information on all aspects of the technique, ranging from the basics of performing the examination to the features of sometimes complex pathological states. The book is intended for anyone interested in non-invasive vascular diagnosis including radiologists, vascular surgeons and ultrasound/peripheral vascular technologists. Other groups may find individual chapters appealing: carotid/cardiac sonography for cardiologists, fetal sonography for obstetricians or carotid sonography for neurologists. Each chapter is not only a guide to duplex evaluation, but also provides valuable information about vascular dynamics of the organ system under discussion. Physicians or technologists reading this book should come away with a well-rounded background in state-of-the-art duplex sonography and will undoubtedly discover new possibilities for using this non-invasive vascular technique.

Download or read book Radiology of the small intestine written by Pierre Bret and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a tradition behind the current radiologic examination of the small bowel. Many of the great names in gastrointestinal radiology have established their reputations on the basis of their work in the small bowel. This is an area which is assuming ever greater importance for radiologists as its mucosal surface continues to elude the endos copist. Moreover, it is an aspect of radiology which calls for the greatest technical and interpretative skill. It is a great pleasure to welcome the English language version of this beautiful work on Radiology of the Small Intestine. English speaking physicians are frequently not as familiar with the large body of work published in French as they should be. Tant pis ! Dr. Bret and his co-workers have been pioneers in the pursuit of excellence in gastrointestinal radiology. During all the years that I have been involved in this field, I have admired their work.

Download or read book Tumor Ablation written by Eric van Sonnenberg and published by Springer Science & Business Media. This book was released on 2008-09-08 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is an enormous sense of excitement in the communities of cancer research and cancer care as we move into the middle third of the ?rst decade of the 21st century. For the ?rst time,there is a true sense of c- ?dence that the tools provided by the human genome project will enable cancer researchers to crack the code of genomic abnormalities that allow tumor cells to live within the body and provide highly speci?c, virtually non-toxic therapies for the eradication,or at least ?rm control of human cancers. There is also good reason to hope that these same lines of inquiry will yield better tests for screening, early detection, and prev- tion of progression beyond curability. While these developments provide a legitimate basis for much op- mism, many patients will continue to develop cancers and suffer from their debilitating effects, even as research moves ahead. For these in- viduals, it is imperative that the cancer ?eld make the best possible use of the tools available to provide present day cancer patients with the best chances for cure, effective palliation, or, at the very least, relief from symptoms caused by acute intercurrent complications of cancer. A modality that has emerged as a very useful approach to at least some of these goals is tumor ablation by the use of physical or physiochemical approaches.

Download or read book Otoneurosurgery written by William Pellet and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctors Pellet, Cannoni and Pech have joined forces to write a masterly work on the subject of otoneurosurgery and tumors of the base of the skull. The anatomic illustrations, derived from their meticulous dissections, are of excellent quality and a credit to the famed tradition of French neuroanatomists of the past. It is evident that the operative techniques described by these surgeons indicate that they have spent a great deal of time in the dissecting-room and that they have completely mastered the temporal bone. A perfect knowledge of the fundamental anatomy of the petrous bone is essential before embarking on the difficult surgical procedures in this region of the brain and base of the skull. Reading this work makes it abundantly clear that the results of this type of sur gery are vastly improved when neurosurgeons and otologists combine their skills. Each of these specialists brings his unique experience and entire knowledge to the operation for the greater benefit of the patient. We wish to congratulate Doctors Pellet, Cannoni and Pech on the publication of this excellent work. March 1990 William F. House, MD William E.

Download or read book Color Atlas of Vascular Tumors and Vascular Malformations written by Odile Enjolras and published by Cambridge University Press. This book was released on 2007-04-02 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hemangiomas and superficial vascular malformations are disfiguring birthmarks that can occur over 65% of a child's body. This atlas will focus on the classification, multidisciplinary approach, recognition and identification, and treatment options for this class of pathology. Vascular malformations, composed of malformed vessels, never regress and sometimes expand rapidly. They occur in any body part including viscera. They cause cosmetic problems, functional disability and can be life threatening and require radiologic imaging and pathology to recognize and perform differential diagnosis on various vascular anomalies. In addition, new techniques, including molecular biology procedures, have evolved allowing less invasive and a more effective approach to diagnosis and treatment.

Download or read book Coronary Pressure written by N.H. Pijls and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiologists must answer three important questions when evaluating and treating patients with a coronary artery stenosis. As a physiologist: "What is the effect of this stenosis on coronary blood flow and myocardial function?"; as a clinician: " Is this lesion responsible for the patient's symptoms?"; and finally as an interventionalist: "Will revascularization of this artery improve the patient?" Fundamentally, the answer to these questions can be given to a large extent by measuring coronary pressure. That is the rationale of writing this book. 1. 1 Historical overview. Andreas Gruentzig and most interventional cardiologists in the early days of PTCA, had the intuitive feeling that pressure measurements could help to establish the severity of a coronary stenosis and to monitor the progress and result of a coronary intervention. At that time, measuring coronary pressure by the balloon catheter was part of a standard procedure. A residual transstenotic gradient of less than 15 mmHg was generally considered as a good result. Later, however, it turned out that measuring these (resting) gradients with balloon catheters was inaccurate an only had a limited prognostic value. Moreover, because there was no consistent theory to correlate pressure measurements to blood flow, the interest in measuring coronary pressures faded and disappeared almost completely with the introduction of new balloon catheters not intended for pressure measurement.
