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: To present an application of the anisotropic diffusion (AD) method to improve the accuracy of the functional images of perfusion parameters such as cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) generated from cerebral CT perfusion studies using multi-detector row CT (MDCT). Materials and Methods: Continuous scans (1 sec/rotation ×60 sec) consisting ...

Cystic adenomatoid malformation is a rare pulmonary hamartomatous lesion, of an unknown etiology. Report a singular case of CAM of one newborn, with marked respiratory distress. Using different method (chest X-ray, Multidetector row CT associated at multiplanar and three-dimensional reconstructions), we obtained an accurate diagnosis of site and nature, critical for a correct therapeutic approach.

PURPOSE To prospectively assess the accuracy of combined wash-in and washout characteristics at dynamic contrast material-enhanced multi-detector row computed tomography (CT) in distinguishing benign from malignant solitary pulmonary nodules. MATERIALS AND METHODS Institutional review board approval and informed consent were obtained. The study included 107 patients (62 men, 45 women; mean ag...

CONTEXT The clinical validity of using computed tomography (CT) to diagnose peripheral pulmonary embolism is uncertain. Insufficient sensitivity for peripheral pulmonary embolism is considered the principal limitation of CT. OBJECTIVE To review studies that used a CT-based approach to rule out a diagnosis of pulmonary embolism. DATA SOURCES The medical literature databases of PubMed, MEDLIN...

cardiovascular disease remains the principal cause of death in the modernized world.   several novel noninvasive imaging techniques have been recently developed to improve diagnosis of cardiac and coronary disease.   of these advances, multidetector computed tomographic (mdct) angiography has evolved most dramatically to transform computed tomography from a single-slice trans-axial modality to ...
