Abstract Background A wide variety of congenital thoracic aortic variants and pathological anomalies could be assessed recently in diagnostic interventional radiology. Multi-detector computed tomography (MDCT) is one the most important non-invasive tools for their detection. The aim study was to evaluate role MDCT scanning diagnosis anatomic diseases pediatric patients. Results Thirty patients ...

BACKGROUND A lots of articles published regarding the usefulness of multidetector-row computed tomography (MDCT) in children with congenital heart disease (CHD) mostly describe that it can be an alternative to the invasive catheterization and angiography. The unique diagnostic features of this imaging modality have been largely ignored or disregarded. We described the pathological conditions th...

Background: Preoperative assessment of patients with aortic valve stenosis (AS) relies on the evaluation of AS severity (aortic valve area, AVA) and left ventricular ejection fraction (LVEF) by echocardiography, and of coronary artery anatomy by coronary angiography. Aim: To evaluate the feasibility and accuracy of contrast-enhanced multidetector computed tomography (MDCT), as a single non-inva...

This paper presents a study of the Modified Discrete Cosine Transform (MDCT) and its implications for audio coding and error concealment from the perspective of Fourier frequency analysis. A relationship between the MDCT and DFT via Shifted Discrete Fourier Transform (SDFT) is established, which provides a possible fast implementation of MDCT employing an FFT routine. The concept of Time Domain...

The aim of this study was to reveal biometric peculiarities of New Zealand white rabbit antebrachium (radius and ulna) by means of three-dimensional (3D) reconstruction of multidetector computed tomography (MDCT) images. Under general anesthesia, the antebrachiums of a total of sixteen rabbits of both sexes were scanned with a general diagnostic MDCT. Biometric measurements of the reconstructed...

PURPOSE To evaluate the diagnostic accuracy of multidetector computed tomography (MDCT) for preoperative staging of renal cell carcinoma (RCC) using the 1997 TNM (tumor, node, metastasis) classification. MATERIALS AND METHODS We conducted a retrospective review of MDCT in 57 consecutive patients with RCC performed for tumor staging before radical (n = 51) or partial nephrectomy (n = 6). The s...

OBJECTIVE To assess multidetector-row computed tomographic (MDCT) urography for detection of recurrence of bladder tumor after transurethral resection (TUR), and to assess significance of the MDCT findings like urothelial enhancement or thickening as a recurrence. METHODS A total of 216 MDCT urography examinations were performed for 100 patients undergoing follow-up after TURs were reviewed b...

PURPOSE Although asymptomatic coronary artery occlusive disease is common in stroke patients, the long-term advantages of undergoing evaluation for coronary arterial disease using multi-detector coronary computed tomography (MDCT) have not been well established in stroke patients. We compared long-term cardio-cerebrovascular outcomes between patients who underwent MDCT and those who did not. ...

conclusion the designed split-bolus mdct technique can be proposed alternatively to triphasic mdct and in a single-pass to pvp in the initial staging and in the follow-up respectively in oncologic patients. patients and methods we retrospectively analyzed the follow-up split-bolus 64-detector row ct protocol in 36 oncologic patients to characterize focal liver lesions. the split-bolus mdct prot...
