We present an unusual case of an intracardiac Eustachian valve cyst observed concurrently with atresia of the coronary sinus ostium, a persistent left superior vena cava (LSVC) and a bicuspid aortic valve. There have been several echocardiographic reports of Eustachian valve cysts; however, there is no report of multidetector computed tomography (MDCT) findings related to a Eustachian valve cys...

Tegmen level and mastoid bone thickness are important parameters of surgical risk in middle ear region surgeries. This retrospective cohort study was conducted to provide a classification for the regions. The population comprised 300 patients who underwent multidetector computed tomography (MDCT) various indications. Patients with no pathology that disrupted structure temporal were included stu...

AIMS We evaluated the distribution and composition of atherosclerotic plaques at bifurcations with intravascular ultrasound-virtual histology (IVUS-VH) and multidetector computed tomography (MDCT) in relation to the bifurcation angle (BA). METHODS AND RESULTS In 33 patients (age 63±11 years, 79% male) imaged with IVUS-VH and MDCT, 33 bifurcations were matched and studied. The analysed main ve...

BACKGROUND The optimal diagnostic test for detecting acute pulmonary embolism (APE) is still under discussion. The ventilation /perfusion scanning has been the preferred examination for several decades, but with the development of new tests the diagnostic possibilities have increased. It is necessary to evaluate them from the cost-effectiveness perspective. The goal of this study was to evaluat...

OBJECTIVES This study examined whether multidetector computed tomography (MDCT) improves the ability to define peri-infarct zone (PIZ) heterogeneity relative to magnetic resonance imaging (MRI). BACKGROUND The PIZ as characterized by delayed contrast-enhancement (DE)-MRI identifies patients susceptible to ventricular arrhythmias and predicts outcome after myocardial infarction (MI). METHODS...

OBJECTIVES The aim of this study was to determine whether 64-slice multidetector computed tomography (MDCT) can differentiate coronary reperfusion with Thrombolysis In Myocardial Infarction (TIMI) flow grade 3 from TIMI flow grade ≤ 2 after ST-segment elevation myocardial infarction (STEMI). BACKGROUND Multidetector computed tomography has become a popular modality for noninvasive coronary ar...

OBJECTIVE To compare the image quality and radiation dose from high pitch dual source CT (128-DSCT) versus those from retrospective acquisition with 64-row multidetector CT (64-MDCT) in triple rule-out studies. MATERIAL AND METHODS We retrospectively studied 60 patients with acute chest pain: 30 with a retrospective EKG acquisition with 64-MDCT and 30 with high pitch 128-DSCT. We quantitative...

BACKGROUND Diagnosis of extracardiac intrathoracic vascular anomalies is of clinical importance, but remains challenging. Traditional imaging modalities, such as radiography, echocardiography, and angiography, are inherently limited by the difficulties of a 2-dimensional approach to a 3-dimensional object. We postulated that accurate characterization of malformations of the aorta would benefit ...

Abstract. The modified discrete cosine transform (MDCT) and modified discrete sine transform (MDST) both for the evenly and oddly stacked systems are perfect reconstruction cosine/sine–modulated filter banks based on time domain aliasing cancellation (TDAC) employed in the current international audio coding standards and commercial audio compression products. Based on the matrix representation ...
