OBJECTIVE To evaluate the effect of thin overlapping reconstruction on the attenuation of small (< or =3 cm) renal cysts in the nephrographic phase of multidetector CT (MDCT). MATERIALS AND METHODS We scanned a phantom kidney containing spheres of various sizes (10, 20, and 30 mm) using both 4- and 16-channel MDCT scanners, and reconstructed images with various slice thickness (T, mm) and int...

BACKGROUND The study objective was to assess the efficacy of 16-slice multidetector row computed tomography (MDCT) in estimating residual stenosis and successful reperfusion after thrombolysis in patients with ST-elevation myocardial infarction (STEMI). METHODS AND RESULTS A total of 31 patients with STEMI underwent MDCT scanning within 6 h (mean 4.6+/-1.1) after thrombolysis and the results ...

Multidetector row computed tomographic (MDCT) assessment of aortic annulus dimensions and frame position and deployment have been associated with paravalvular aortic regurgitation (PAVR) after transcatheter aortic valve implantation (TAVI). The present evaluation investigated the (pre- and postprocedure) MDCT associates of PAVR ≥2+. In total, 123 patients referred for TAVI underwent clinical ev...

Noninvasive CT coronary angiography is a promising coronary imaging technique. In spite of the unprecedented temporal and spatial resolution and the inability to perform therapeutic interventions in the same session multi-detector computed tomography (MDCT) has been considering a promising alternative, non invasive tool for coronary artery imaging due to its high sensitivity and specificity for...

BACKGROUND Accurate, non-invasive characterization of culprit lesions in patients after acute myocardial infarction (AMI) remains challenging. In this prospective study, multidetector row computed tomography (MDCT) is used to assess culprit and active complex lesions in patients early after AMI. METHODS AND RESULTS We enrolled 103 patients with first non ST-elevation AMI who underwent 64-slic...

BACKGROUND This study was performed to evaluate the diagnostic role of electrocardiographically gated multidetector-row computed tomography (MDCT) for prosthetic valve obstruction (PVO) in the aortic position. METHODS AND RESULTS Between 2002 and 2006, 9 patients were diagnosed with PVO of an aortic bileaflet mechanical valve based on echocardiographic and cineradiographic criteria. These 9 p...

OBJECTIVE In a previous in vitro study we have demonstrated that atherosclerotic plaque components can be characterized with multidetector computed tomography (MDCT) based on differences in Hounsfield values (HV). Now we evaluated the use of MDCT in vivo to characterize and quantify atherosclerotic carotid plaque components compared with histology as reference standard. METHODS AND RESULTS Fi...

Life-threatening hemoptysis is a severe condition that requires rapid diagnosis and treatment. One of the treatments of choice is embolization. The initial assessment aims to locate the origin and cause of bleeding. The technological advance of the development of multidetector computed tomography (MDCT) has changed the management of patients with life-threatening hemoptysis. MDCT angiography ma...

INTRODUCTION: Microinfarction resulting from microembolized plaques is common in patients following percutaneous coronary intervention (PCI) and acute coronary syndrome. MRI has shown to be able to demonstrate the acute and subacute effects of microembolization. The ability of MRI and multidetector compute tomography (MDCT) to quantify the chronic effects of microembolization on left ventricula...

Echocardiography is the mainstay imaging technique for detecting infective endocarditis vegetations but may struggle to detect and characterise complicating features. There is increasing interest in the use of multidetector computed tomography (MDCT) as an adjunct to echocardiography, especially where there is concern for abscess or pseudoaneurysm formation. We present the case of a 70-year-old...
