High Iodine Concentration Contrast Material for Noninvasive Multislice Computed Tomography Coronary Angiography
2006
OBJECTIVE: The objective of this study was to compare intracoronary attenuation on 16-row multislice computed tomography (16-MSCT) coronary angiography using 2 contrast materials (CM) with high iodine concentration. MATERIAL AND METHODS: Forty consecutive patients (29 male, 11 female; mean age, 61 ± 11 years) with suspected coronary artery disease were randomized to 2 groups to receive 100 mL of either iopromide 370 (group 1: Ultravist 370, 370 mg iodine/mL; Schering AG, Berlin, Germany) or iomeprol 400 (group 2: Iomeron 400, 400 mg iodine/mL; Bracco Imaging SpA, Milan, Italy). Both CM were administered at a rate of 4 mL/s. All patients underwent 16-MSCT coronary angiography (Sensation 16; …
State-of-the-art imaging in palaeopathology: the value of multislice computed tomography in visualizing doubtful cranial lesions
2002
Non-invasive imaging techniques are of great value in palaeopathology. Computed tomography (CT) is widely established to visualize changes in human remains that occurred both pre and post mortem. Since 1999 an advanced form of helical CT—so called Multislice-CT (MSCT)—has become available for clinical purposes. We now present for the first time three historic cranial lesions of doubtful aetiology visualized by MSCT. Both original images and virtual reconstructions of the specimens are of high quality. In combination with peri-lesional bone density measurements these images allow an improved assessment of aetiology. The cases presented are diagnosed by MSCT as being of intra vitam nature in …

Prevalence of anatomical variants and coronary anomalies in 543 consecutive patients studied with 64-slice CT coronary angiography
2008
The aim of our study was to assess the prevalence of variants and anomalies of the coronary artery tree in patients who underwent 64-slice computed tomography coronary angiography (CT-CA) for suspected or known coronary artery disease. A total of 543 patients (389 male, mean age 60.5 +/- 10.9) were reviewed for coronary artery variants and anomalies including post-processing tools. The majority of segments were identified according to the American Heart Association scheme. The coronary dominance pattern results were: right, 86.6%; left, 9.2%; balanced, 4.2%. The left main coronary artery had a mean length of 112 +/- 55 mm. The intermediate branch was present in the 21.9%. A variable number …
Right coronary artery arising from pulmonary trunk: assessment with conventional coronary angiography and multislice computed tomography coronary ang…
2009
We present a case of a 59-year-old man who was admitted to the hospital because of atypical chest pain and dyspnea. Conventional coronary angiography showed an anomalous origin of the right coronary artery from the pulmonary trunk. The patient underwent multislice computed tomography in order to clarify the origin and course of the anomalous vessel. The aim of this report is to emphasize the role of multislice computed tomography as an accurate noninvasive imaging tool in the evaluation of coronary artery anomalies.
INFLUENCE OF INTRA-CORONARY ENHANCEMENT ON DIAGNOSTIC ACCURACY WITH 64-SLICE CT CORONARY ANGIOGRAPHY
2008
We assessed the effect of intra-coronary attenuation on diagnostic accuracy using 64-slice computed tomography coronary angiography (CT-CA). We enrolled 170 patients with suspected coronary artery disease who underwent conventional coronary angiography (CA) and 64-slice CT-CA (100 ml of Iomeprol 400 mg I/ml at 4 ml/s). The study population was divided into two groups (85 patients each based on median attenuation of 326 HU) based on mean arterial attenuation; group 1 with low attenuation and group 2 with high attenuation. Diagnostic accuracy for the detection of significant coronary artery stenosis was determined for both groups using CA as reference standard. Overall, 163 significant stenos…
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…
ECG-gated multislice computed tomography angiography as a comprehensive non-invasive imaging tool in patient with aortic coarctation
2021
We describe a case of a 52-year-old-woman with aortic coarctation demonstrated by means of 40-slice MSCT angiography. Based on the information extracted from MSCT it was possible to display the anatomical configuration of the disease, the thoraco-abdominal collateral pathways. The best therapeutic approach was established on the basis of MSCT findings. MSCT is a reliable and comprehensive tool for the assessment of adult patients with aortic coarctation.

Diagnostic accuracy of 64-slice computed tomography coronary angiography in patients with low-to-intermediate risk
2007
Purpose. Our aim was to evaluate the diagnostic accuracy of 64- slice computed tomography coronary angiography (MSCT-CA) for detecting significant stenosis (≥50% lumen reduction) in a population of patients at low to intermediate risk. Materials and methods. We studied 72 patients (38 men, 34 women, mean age 53.9±8.0 years) with atypical or typical chest pain and stratified in the low- to intermediate risk category. MSCT-CA (Sensation 64 Cardiac, Siemens, Germany) was performed after IV administration of 100 ml of iodinated contrast material (Iomeprol 400 mgI/ml, Bracco, Italy). Two observers, blinded to the results of conventional coronary angiography (CAG), assessed the MSCT-CA scans in c…
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…
