13. Análise comparativa ex vivo dos efeitos do preparo de canais curvos com diferentes sistemas rotatórios, por meio de tomografia computadorizada helicoidal / Ex vivo comparative analysis of the effects of root canal preparation with different rotary systems by helicoidal computerized tomography
The aim of this study was to compare the time of preparation, canal transportation, direction of transportation, mean centering ratio, and the percentage of area increase of canals instrumented using three rotary systems, assessed by spiral computed tomography. Forty lower molars with completely formed apices, curvature angle = 20, and radius of curvature <1

16. Spiral computed tomography angiography in the assessment of middle cerebral artery occlusive disease.
There has been no report on the use of spiral computed tomography angiography (CTA) in the investigation of intracranial cerebral artery stenosis. A prospective pilot study was conducted to investigate the feasibility of CTA in the diagnosis of intracranial occlusive disease and its correlation with transcranial Doppler. With transcranial Doppler, 10 patient

17. Utility of intravascular ultrasound in peripheral interventions.
Endovascular imaging techniques encompass a variety of methods, including angiography, computed tomography, magnetic resonance imaging, angioscopy, and intravascular ultrasound. Each method provides unique information regarding the continuity of vascular structures and the morphology and distribution of lesions. Although arteriography has been the "gold stan

18. Preoperative assessment for laparoscopic cholecystectomy: feasibility of using spiral computed tomography.
OBJECTIVE: The authors investigated the preoperative feasibility of using spiral computed tomography (SCT) after intravenous infusion cholangiography (IVC-SCT) for laparoscopic cholecystectomy. SUMMARY BACKGROUND DATA: In laparoscopic cholecystectomy, the aberrant or unusual anatomy of the bile duct and severe inflammation or adhesions around the gallbladder

19. Role of spiral volumetric computed tomographic scanning in the assessment of patients with clinical suspicion of pulmonary embolism and an abnormal ventilation/perfusion lung scan.
BACKGROUND: A study was carried out to evaluate the potential place of spiral volumetric computed tomography (SVCT) in the diagnostic strategy for pulmonary embolism. METHODS: In a prospective study 249 patients with clinical suspicion of pulmonary embolism were evaluated with various imaging techniques. In all patients a ventilation/perfusion (V/Q) scan was

20. Petrosal anatomy in the fossil mammal Necrolestes: evidence for metatherian affinities and comparisons with the extant marsupial mole
We present reconstructions of petrosal anatomy based on high-resolution X-ray computed tomography scans for the fossil mammal Necrolestes and for the marsupial mole Notoryctes sp. Compared with other mammals, Necrolestes exhibits a mosaic of plesiomorphic and derived characters, but most of the evidence supports its metatherian status. We revised previous de

21. Acrophialophora fusispora Brain Abscess in a Child with Acute Lymphoblastic Leukemia: Review of Cases and Taxonomy
A 12-year-old girl with acute lymphoblastic leukemia was referred to King Faisal Specialist Hospital and Research Center. The diagnosis without central nervous system (CNS) involvement was confirmed on admission, and chemotherapy was initiated according to the Children Cancer Group (CCG) 1882 protocol for high-risk-group leukemia. During neutropenia amphoter
