AIMS Transseptal puncture (TP) can be a difficult procedure and is not without risk of complications. The purpose of this study was to evaluate the use of three-dimensional multi-detector row computed tomography (MDCT) to localize the fossa ovalis (FO) and facilitate TP in patients undergoing left atrial catheter ablation. METHODS AND RESULTS Fourteen consecutive patients were studied. Thirte...

Am J Physiol Renal Physiol 283: F29–F40, 2002; 10.1152/ajprenal.00252.2000.— The plasma membrane Ca2 -ATPase (PMCA) and the NCX1 Na /Ca2 exchanger regulate intracellular Ca2 concentrations and mediate Ca2 effl...

OBJECTIVE To compare multi-detector computed tomography (MDCT) with cardiac catheterization and transthoracic echocardiography (TTE) in comprehensive evaluation of the global cardiovascular anatomy in patients with pulmonary atresia with ventricular septal defect (PA-VSD). METHODS The clinical and imaging data of 116 patients with PA-VSD confirmed by surgery were reviewed. Using findings at s...

OBJECTIVES This study aimed to compare the accuracy of conventional intraoral (CI) radiography, photostimulable phosphor (PSP) radiography, cone beam computed tomography (CBCT) and multidetector computed tomography (MDCT) for detection of strip and root perforations in endodontically treated teeth. MATERIALS AND METHODS Mesial and distal roots of 72 recently extracted molar were endodonticall...

A Hindmarsh-Rose model perceptibility phantom containing inserts with various in vitro atherosclerotic plaque compositions was constructed and imaged on a clinical 64 slice multidetector (MDCT) system using 80 and 120 kVp settings and two other cone-beam (CBCT) systems at 80 kVp. Perceptibility of the simulated lipid-fibrotic plaque solutions in the images was evaluated by six observers. The ef...

Aim: To explore if gadolinium-ethoxybenzyl-diethylenetriaminepentaacetic acid (Gd-EOB-DTPA)-enhanced MRI provides more accurate information than multi-detector row computed tomography (MDCT) for staging hepatocellular carcinoma (HCC). Methods: We retrospectively investigated 112 patients with HCC who underwent MDCT and Gd-EOB-DTPAenhanced MRI within one month before treatment. Two experienced r...

BACKGROUND The purpose of this study was to investigate the diagnostic efficiency of multidetector computed tomography (MDCT) in the detection of blunt bowel and mesenteric injuries (BBMI), and the role of different experience levels in using MDCT. METHODS This study included a test group of twenty-seven patients with surgically important BBMI in whom the diagnoses were confirmed after surgic...

PURPOSE Contrast enhanced multidetector computed tomography (MDCT) has been used as an alternative to coronary angiography for the assessment of coronary artery disease in the patient of the intermediate risk group. However, coronary calcium is a known limiting factor for MDCT evaluation. We investigated the diagnostic accuracy of 64-channel MDCT with each coronary artery calcium score (CACS) b...

PURPOSE The detection and localization of cerebrospinal fluid (CSF) leakage in patients with spontaneous intracranial hypotension (SIH) is important. The aim of this study was to evaluate the usefulness of multidetector CT (MDCT)-myelography in patients with SIH. METHODS A radiologist retrospectively searched the electronic database to find the patients who had undergone MDCT-myelography for ...

INTRODUCTION Neurofibromatosis type 1 (NF-1) may involve the spine as various abnormalities including bony dysplasia, scoliosis, and nerve sheath tumors. Surgery may be performed for stabilization of the spine. We have seen an increase in requests for multidetector CT (MDCT) imaging with the (three-dimensional) 3D-volume rendered (VR) images in patients evaluated at our institution. We, therefo...
