The modified discrete cosine transform (MDCT) is always employed in transform-coding schemes as the analysis/ synthesis filter bank. In this paper, an efficient algorithm for MDCT and inverse MDCT (IMDCT) computation for MPEG-1 audio layer III and MPEG-2 international audio-coding standards is proposed, using only the type-II DCT. Finally, the proposed algorithm is compared to the similar algor...

Fenestration of the internal jugular vein is a rare malformation. Herein, the authors describe an extreme fenestration of the left internal jugular vein. This anomaly was found incidentally in a 47-year-old male patient undergoing multidetector computed tomography (MDCT) imaging and MDCT angiography evaluation for vertebral artery injury due to cervical trauma. MDCT angiography ...

Abstract Background Urinary bladder tumors are the most common type of detected in patients with gross hematuria. Multidetector computed tomography (MDCT) is an accurate method for detecting lesions. This review aims to describe features MDCT and possible values distinguishing these lesions bladder. Main body In this review, we discuss role evaluation cancer a broad spectrum lesions, including ...

BACKGROUND Identifying the optimal fluoroscopic projection of the aortic valve is important for successful transcatheter aortic valve replacement (TAVR). Various imaging modalities, including multidetector computed tomography (MDCT), have been proposed for prediction of the optimal deployment projection. We evaluated a method that provides 3-dimensional angiographic reconstructions (3DA) of the...

BACKGROUND Both whole-heart magnetic resonance coronary angiography (WH-MRCA) and multidetector computed tomography (MDCT) have been proposed for the noninvasive identification of the coronary stenosis. The authors sought to directly compare the diagnostic accuracy of these noninvasive imaging techniques using the invasive quantitative coronary angiography as a reference standard. METHODS AND...

OBJECTIVE To compare the diagnostic performance of gadoxetic acid-enhanced magnetic resonance (MR) imaging with that of triple-phase multidetector-row computed tomography (MDCT) in the detection of liver metastasis. MATERIALS AND METHODS Our institutional review board approved this retrospective study and waived informed consent. The study population consisted of 51 patients with hepatic meta...

BACKGROUND AND PURPOSE The purpose of this work was to evaluate the possible use of low-dose multidetector CT (MDCT) in cervical clearance of patients with blunt trauma. MATERIALS AND METHODS A total of 191 patients underwent cervical spine MDCT with 6- and 16-MDCT: standard-dose (n = 51) and low-dose MDCT with tube current modulation at high (n = 70) and low (n = 70) tube voltage (kilovolts)...

The purpose of this article is to provide a current review of the spectrum of multidetector CT (MDCT) and MRI findings for a variety of cardiac neoplasms. In the diagnosis of cardiac tumors, the use of MDCT and MRI can help differentiate benign from malignant masses. Especially, the use of MDCT is advantageous in providing anatomical information and MRI is useful for tissue characterization of ...

INTRODUCTION Carcinoid heart disease is a rare condition in adults. Its diagnosis can be easily missed in a patient presenting to a primary care setting. We revised the advantages of using coronary multidetector computed tomography (MDCT) and cardiac magnetic resonance imaging (MRI) in diagnosing this condition. MATERIALS AND METHODS We studied a 65-year-old patient with carcinoid heart disea...

Background: Lateral X-ray of the cervical spine (LCSX) is a common diagnostic tool to detect fractures in hospitalized patients. Its non-invasive nature and cost-effectiveness make it preferred imaging technique for rapid identification fractures. However, its accuracy still subject debate further research needed establish reliability validity. This study aimed determine LCSX detecting patients...
