BACKGROUND The diagnostic accuracy of 64-slice MDCT in comparison with IVUS has been poorly described and is mainly restricted to reports analyzing segments with documented atherosclerotic plaques. OBJECTIVES We compared 64-slice multidetector computed tomography (MDCT) with gray scale intravascular ultrasound (IVUS) for the evaluation of coronary lumen dimensions in the context of a comprehe...

PURPOSE There are no simple guidelines on when to perform multidetector-row computed tomography (MDCT) for diagnosis of obscure acute gastrointestinal bleeding (AGIB). We used a risk scoring system to evaluate the diagnostic power of MDCT for patients with obscure AGIB. MATERIALS AND METHODS Ninety-two patients with obscure AGIB who were referred for an MDCT scan after unsuccessful endoscopic...

MDCT has recently been used as a diagnostic tool to evaluate coronary artery stenosis and to detect coronary artery anomalies. The accuracy of MDCT has improved the assessment of stenosis as the number of detectors has increased. In addition to its excellent role in evaluating coronary artery stenosis, MDCT can provide information regarding the left ventricular function without having to perfor...

PURPOSE We aimed to evaluate the accuracy of multidetector computed tomography (MDCT) venous mapping for the localization of the right adrenal veins (RAV) in patients suffering from primary aldosteronism. METHODS MDCT scans of 75 patients with primary aldosteronism between March 2008 and November 2011 were evaluated by two readers (a junior [R1] and a senior [R2] radiologist) according to the...

BACKGROUND incidental detection of solid renal masses has been increasing since the multidetector computed tomography (MDCT) scanner was introduced. PURPOSE to evaluate the clinico-radio-pathologic features of a solitary solid renal mass at MDCT examination. MATERIAL AND METHODS a total of 466 non-fatty solid renal masses in 466 patients undergoing nephrectomy were evaluated by MDCT examina...

The modified discrete cosine transform (MDCT) and inverse MDCT (IMDCT) are two of the most computational intensive operations in MPEG audio coding standards. A new mixed-radix algorithm for efficient computing the MDCT/IMDCT is presented. The proposed mixed-radix MDCT algorithm is composed of two recursive algorithms. The first algorithm, called the radix-2 decimation in frequency (DIF) algorit...

Ziel: Ziel der Studie war die Häufigkeit von typischen Artefakten der high-pitch Computertomografie (HPCT) bei low-dose Untersuchungen von Kindern im Vergleich zur MDCT zu evaluieren und die effektive Dosis (Deff) zu berechnen. Material und Methoden: 35 Patienten (17 Jungen, 18 Mädchen; Durchschnittsalter 112±69 Monate) wurden in diese retrospektive Studie eingeschlossen. Bei allen Patienten wu...

PURPOSE To determine the impact of iodinated contrast material extravasation at MDCT in selecting patients with pelvic fractures that require vascular embolization. PATIENTS AND METHODS All patients with severe pelvic fracture admitted to the trauma unit between 1998 and 2004 underwent contrast enhanced MDCT prior to additional specific treatment. All patients with extravasation underwent imm...

A 61-year-old woman with hypercholesterolemia, hypertension and diabetes mellitus was referred to hospital for the evaluation of chest pain at rest. Eccentric 50% stenosis in the proximal right coronary artery was detected by 64-slice multidetector row computed tomography (MDCT). The plaque morphology was considered as soft by Color Code Plaque (CCP) analysis. Seven days after MDCT, chest pain ...

OBJECTIVE In patients with hypertrophic obstructive cardiomyopathy (HOCM), left atrial (LA) volume measurement is very important to provide prognostic information. Recent studies demonstrated that multidetector CT (MDCT) is useful to assess the changes in LA volume. Our aim was to examine the utility of a follow-up cardiac MDCT for long-term evaluation of the effect of percutaneous transluminal...
