Delayed Dual-Energy CT (DECT) and conventional cardiac CT angiography (CCTA) in detection of chronic myocardial scar tissue: do we need delayed acquisition? Comparison with MRI

چکیده
Methods 19 patients (m/f-16/3, mean age 59,6± 2,0 years) with history of myocardial infarction ( >1 year) were prospectively enrolled in the study. The CCTA protocol consisted of prospectively gated CTA and DECT. DECT was performed with single-tube 64-row CT in gemstone spectral imaging (GSI) mode with 8 min delay after contrast media injection. Using a 4-point transmurality scale CCTA images were visually assessed for first-pass arterial enhancement deficit and late enhancement in DECT images using iodine distribution maps. Per-segment analysis was performed by 2 observers independently. LGE MRI

Dual-time-point FDG-PET/CT Imaging of Temporal Bone Chondroblastoma: A Report of Two Cases
Temporal bone chondroblastoma is an extremely rare benign bone tumor. We encountered two cases showing similar imaging findings on computed tomography (CT), magnetic resonance imaging (MRI), and dual-time-point 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT. In both cases, CT images revealed temporal bone defects and sclerotic changes around the tumor. Most parts of the ...

Background: Prospectively electrocardiography (ECG)-triggered high-pitch spiral coronary computed tomography angiography (CCTA) is a unique scan mode for dual-source CT (DSCT). Our reports aim to compare image quality and radiation dose of CCTA using high-pitch spiral or sequential acquisition mode in patients with low and stable heart rates. Materials and Methods: Patients with low and stable ...

The purpose of this study is to evaluate a direct measure of calcium burden by using dual-energy computed tomography (DECT) during contrast-enhanced coronary imaging, potentially eliminating the need for an extra noncontrast X-ray acquisition. The ambiguity of separation of calcium from contrast material on contrast-enhanced images was solved by using virtual noncontrast images obtained by DECT...
متن کاملDiagnostic accuracy of coronary CT angiography combined with dual-energy myocardial perfusion imaging for detection of myocardial infarction
The aim of the present study was to evaluate the diagnostic accuracy of second generation dual-energy computed tomography (DECT) myocardial perfusion imaging for the detection of myocardial infarction (MI) in patients with suspected MI. In total, 56 patients underwent DECT. Among those, 40 patients had MI that was detected by catheter coronary angiography and cardiac troponin I elevation and ev...
متن کاملDetection of extra-cardiac hypermetabolic foci by [18F]FDG PET/CT in case of infective endocarditis and post antibiotic therapy response assessment
The diagnosis of prosthetic valve endocarditis continues to present a diagnostic challenge, due to the lower sensitivity of the modified Duke criteria and a higher percentage of negative or inconclusive echocardiography results. Diagnostic delay might result in significant morbidity/mortality. Imaging modalities like 2-[18F]fluoro-2-deoxy-D-glucose positron emission tomography/comput...
