Prevalence and characteristics of coronary artery disease in a population with suspected ischaemic heart disease using CT coronary angiography: corre…
2008
Purpose. This study was undertaken to describe the correlation between the distribution of coronary artery disease (CAD) in a symptomatic population with suspected ischaemic heart disease, cardiovascular risk factors (RF) and clinical presentation. Materials and methods. We studied 163 patients (mean age 65.5 years; 101 men and 62 women) referred for multidetector computed tomography coronary angiography (MDCT-CA) to rule out CAD. The patients had no prior history of revascularisation or myocardial infarction. We analysed how the characteristics of CAD (severity and type of plaque) can change with the increase in RF and how they are related to different clinical presentations. Results. Pati…

Coronary plaque imaging with multislice computed tomography: technique and clinical applications.
2006
The composition of an atherosclerotic lesion, rather than solely the degree of stenosis, is considered to be an important determinant of acute coronary events. Whereas until recently only invasive techniques have been able to provide clues about plaque composition with consistent reproducibility, several recent studies have revealed the potential of multislice computed tomography (MSCT) for noninvasive plaque imaging. Coronary MSCT has the potential to detect coronary plaques and to characterize their composition based on the X-ray attenuating features of each structure. MSCT may also reveal the total plaque burden (calcified and noncalcified components) for individual patients with coronar…
Esame radiologico del torace nell’invecchiamento cardiaco
2006
L’invecchiamento e un processo fisiologico, definito omeostenosi caratterizzato da un progressivo declino dell’omeostasi di diversi organi e apparati in assenza di segni e/o sintomi di malattia. Le modificazioni anatomo-patologiche a carico dell’apparato cardiocircolatorio iniziano a comparire gia dalla terza decade di vita con incremento del grasso pericardico, progressivo irrigidimento delle valvole cardiache con segni di insufficienza e/o stenosi. Nella parete cardiaca si puo documentare ipertrofia del miocardio con incremento volumetrico delle fibrocellule muscolari lisce, prevalentemente a carico del distretto sinistro. Analoghe modificazioni sono riscontrabili nella parete vasale del …
Comprehensive cardiovascular ECG-gated MDCT as a standard diagnostic tool in patients with acute chest pain
2007
Acute myocardial infarction, pulmonary embolism, and aortic dissection are diseases associated with acute chest pain and may lead to severe morbidity and mortality. These diseases may not be trivial to diagnose in the settings of emergency room. ECG-gated multi-detector computed tomography (MDCT), already established for the assessment of pulmonary embolism and aortic dissection, provides reliable information regarding the triage of patients with acute coronary syndrome in the emergency room. MDCT recently appeared to be logistically feasible and a promising comprehensive method for the evaluation of cardiac and non-cardiac chest pain in emergency department patients. The possibility to sca…

Prevalence of coronary artery intramyocardial course in a large population of clinical patients detected by multislice computed tomography coronary a…
2008
Background: Intramyocardial course, an inborn coronary anomaly, is defined as a segment of a major epicardial coronary artery that runs intramurally through the myocardium; in particular, we distinguish myocardial bridging, in which the vessel returns to an epicardial position after the muscle bridge, and intramyocardial course, which is described as a vessel running and ending in the myocardium. Purpose: To evaluate the prevalence of myocardial bridging and intramyocardial course of coronary arteries as defined by multidetector computed tomography (MDCT) angiography. Material and Methods: The study population consisted of 242 consecutive patients (211 men, 31 women; mean age 59±6 years) w…
Imaging techniques for the vulnerable coronary plaque
2007
The goal of this article is to illustrate the main invasive and noninvasive diagnostic modalities to image the vulnerable coronary plaque, which is responsible for acute coronary syndrome. The main epidemiologic and histological issues are briefly discussed in order to provide an adequate background. Comprehensive coronary atherosclerosis imaging should involve visualization of the entire coronary artery tree and plaque characterization, including three-dimensional morphology, relationship with the lumen, composition, vascular remodelling and presence of inflammation. No single technique provides such a comprehensive description, and no available modality extensively identifies the vulnerab…
Can ECG-gated MDCT be considered an obligatory step to plan and manage a new chest-pain unit?
2007
The recent improvements in multi-detector computed tomography technology and its application in cardiac field allow to consider this non-invasive imaging technique as a promising comprehensive method for detecting significant coronary stenoses in a chest-pain unit. The possibility to use the ECG-synchronisation acquisition protocol, normally limited to the cardiac volume, for the entire thoracic vascular system should have the remarkable potential to reduce invasive and non-invasive procedures actually used to investigate acute chest pain and the number of unnecessary hospital admissions without reducing appropriate admissions in patients with chest pain.
3D reconstruction techniques made easy: know-how and pictures
2005
Three-dimensional reconstructions represent a visual-based tool for illustrating the basis of three-dimensional post-processing such as interpolation, ray-casting, segmentation, percentage classification, gradient calculation, shading and illumination. The knowledge of the optimal scanning and reconstruction parameters facilitates the use of three-dimensional reconstruction techniques in clinical practise. The aim of this article is to explain the principles of multidimensional image processing in a pictorial way and the advantages and limitations of the different possibilities of 3D visualisation.
Myocardial blood flow quantification for evaluation of coronary artery disease by computed tomography
2017
During the last decade coronary computed tomography angiography (CTA) has become the preeminent non-invasive imaging modality to detect coronary artery disease (CAD) with high accuracy. However, CTA has a limited value in assessing the hemodynamic significance of a given stenosis due to a modest specificity and positive predictive value. In recent years, different CT techniques for detecting myocardial ischemia have emerged, such as CT-derived fractional flow reserve (FFR-CT), transluminal attenuation gradient (TAG), and myocardial CT perfusion (CTP) imaging. Myocardial CTP imaging can be performed with a single static scan during first pass of the contrast agent, with monoenergetic or dual…

2005
One hundred twenty patients in sinus rhythm with suspected coronary artery disease who underwent multislice computed tomography of the heart and conventional coronary angiography were retrospectively selected. The population was divided into 2 groups depending on their calcium score (CS) (e.g., low CS and high CS). The diagnostic accuracy of multislice computed tomographic scans for detecting significant lesions (>50% lumen reduction) in both groups was compared with quantitative coronary angiography. The sensitivity and specificity of multislice computed tomography were 90% and 92%, and 97% and 91% for low and high CS groups, respectively.

Evaluation of Cardiac Volumetric and Functional Parameters
2012
The milestone definition of “Cardiac Function” has to be attributed to William Harvey, the discoverer of the circulation, who in 1628 stated: “The movement of the blood is constantly in a circle, and is brought about by the beat of the heart” [1, 2]. From a modern point of view, the main function of the heart is the delivery of oxygen to metabolizing tissues. Since oxygen delivery is dependent on (1) the oxygen-carrying capacity of blood, (2) the flow output from the heart, and (3) regional distribution of flow, then the heart is nowadays regarded as a pump with the function of supplying flow in blood vessels [2].
Coronary artery anomalies: incidence, pathophysiology, clinical relevance and role of diagnostic imaging
2006
Conventional coronary angiography is the gold standard for the diagnosis of coronary artery anomalies. Coronary anomalies are relatively rare findings in patients undergoing conventional coronary angiography for suspected obstructive coronary artery disease. Recently, the increasing performance of diagnostic techniques, such as electron beam tomography (EBT), magnetic resonance (MR) and, more recently, multislice computed tomography (MSCT), has enabled their application to cardiac imaging. MSCT, in particular, has a prominent role in coronary imaging due to its spatial and temporal resolution and three-dimensional capabilities. We report the incidence and pathophysiology of coronary artery …

Approccio diagnostico non invasivo con tomografia computerizzata multidetettore a 40 strati per lo studio della malattia aterosclerotica coronarica
2007
Background. Multidetector computed tomography coronary angiography (MDCT-CA) is a non-invasive technique that clearly shows coronary anatomy and correctly identifies plaque location and morphology. In this study we assessed diagnostic accuracy of MDCT-CA in detectiong significant stenosis in patients with clinically relevant coronary tree disease. Methods. Fifty patients (38 males, 12 females, mean age 60.9 ± 9.2 years) with atypical chest pain, stable or unstable angina pectoris, or non-ST-elevation myocardial infarction underwent MDCT-CA (Brilliance 40, Philips Medical Systems, Cleveland, OH, USA) within 3 days before diagnostic conventional coronary angiography. Inclusion criteria were s…

Atherosclerotic pattern of coronary myocardial bridging assessed with CT coronary angiography
2012
The aim of our study was to evaluate the atherosclerotic pattern of patients with coronary myocardial bridging (MB) by means of CT Coronary Angiography (CT-CA). 254 consecutive patients (166 male, mean age 58.6 +/- A 10.3) who underwent 64-slice CT-CA according to current clinical indications were reviewed for the presence of MB and concomitant segmental atherosclerotic pattern. Coronary plaques were assessed in all patients enrolled. 73 patients (29%) presented single (90%) or multiple (10%) MB, frequently (93%) localized in the mid-distal left anterior descending artery. The MB segment was always free of atherosclerosis. Segments proximal to the MB presented: no atherosclerotic disease (n…
