The purpose of our study was to evaluate reliability of left ventricular (LV) function and mass quantification in cardiac DSCT exams comparing manual contour tracing and a region-growing-based semiautomatic segmentation analysis software. Thirty-three consecutive patients who underwent cardiac DSCT exams were included. Axial 1-mm slices were used for the(More)
Percutaneous and endovascular techniques have shown their efficacy in the treatment of a great variety of pathologies. The advances in diagnostic imaging as well as the development of new materials have made it possible to carry out new procedures that were unthinkable not many years ago. The irruption of this new form of treating patients has had, is(More)
INTRODUCTION To compare left atrial performance with dual-source CT (DSCT) with respect to magnetic resonance imaging (MRI) in orthotopic heart transplant recipients. METHODS Twenty-nine consecutive heart transplant recipients (27 male; mean age 64.1 +/- 13 years; mean time from transplantation 122.8 +/- 69.7 months) referred for exclusion of cardiac(More)
Evaluation of the cardiovascular system with magnetic resonance (CMR) has become one of the most relevant and up-to-the-minute clinical applications of this diagnostic technique, as CMR makes possible an exact and reproducible study of the anatomy and function of the heart and great vessels. The complexity of this technique is mainly due to the anatomical(More)
Multidetector-row computed tomography (MDCT) plays an essential role in oncologic imaging as the modality of mapping out the treatment strategy at staging, assessing response to the treatment, and following up patient outcome after the treatment. Even without electrocardiogram gating, MDCT provides accurate information about the heart. In the group of(More)
OBJECTIVE To evaluate the effect of average heart rate on the quality of images of the coronary arteries and to determine the optimal reconstruction interval in nonselected patients undergoing DSCT coronary imaging. MATERIALS AND METHODS We studied 28 consecutive subjects (26 men, 2 women; mean age 60+/-12 years) undergoing contrast-enhanced DSCT (Somatom(More)
BACKGROUND To study the biochemical progression-free survival (BPFS) achieved by a group of high risk patients in accordance with D'Amico's classification treated with radical prostatectomy. To identify the clinical-pathological variables which are influential in biochemical progression-free survival and, if possible, use them to design a prognostic model.(More)
OBJECTIVES To evaluate the interobserver agreement in quantifying left ventricular function and mass and to assess the accuracy of conventional manual contour tracing compared to semiautomatic segmentation analysis software. MATERIAL AND METHODS Twenty consecutive subjects who underwent cardiac DSCT with retrospective ECG-gating were included. Two(More)
OBJECTIVES To improve the predictive efficacy of the D'Amico risk classification system with magnetic resonance imaging (MRI) of the pelvis. MATERIAL AND METHODS We studied 729 patients from a series of 1310 radical prostatectomies for T1-T2 prostate cancer who underwent staging pelvic MRI. Each patient was classified with T2, T3a or T3b MRI, and N (+)(More)
