Disease relevance of Tomography, Spiral Computed


High impact information on Tomography, Spiral Computed

  • In conclusion, MRA has a high diagnostic accuracy for HCC > or =10 mm and is more sensitive than triphasic helical CT in nodules sized 10 to 20 mm [6].
  • All patients underwent a spiral computed tomography (CT) scan, 99mTc-HYNIC annexin V tomography, and subsequent surgical resection of the suspected primary or recurrent tumor [7].
  • AIM: To compare the performance of spiral CT and operative assessment against formal (TNM) pathological staging [8].
  • We investigated the relationship between airway wall thickness as assessed by helical computed tomography and two components of airway responsiveness, airway sensitivity and reactivity, in patients with stable asthma with (n = 23) and without (n = 22) inhaled steroid treatment [9].
  • Follow-up ranged from 3 to 78 months (mean, 24 months +/- 21) and included measurement of alpha-fetoprotein level, ultrasonography at 3-month intervals, and spiral computed tomography at 6-month intervals [10].

Associations of Tomography, Spiral Computed with chemical compounds

  • Petrosal bone: coronal reconstructions from axial spiral CT data obtained with 0.5-mm collimation can replace direct coronal sequential CT scans [26].
  • All patients underwent monoor multi-slice spiral CT and MRA with gadolinium injection (both within 24 hours of entry to the study) [27].
  • PURPOSE: To evaluate whether mangafodipir trisodium (Mn-DPDP)-enhanced magnetic resonance (MR) imaging surpasses dual-phase spiral computed tomography (CT) in differentiating focal liver lesions [28].
  • MATERIALS AND METHODS: One hundred two patients (64 men, 38 women) with neoplastic (n = 85) and nonneoplastic focal lesions (n = 17) were prospectively assigned to biphasic injection group A or B and received 180 mL of iopromide containing 370 or 300 mg of iodine per milliliter, respectively, during spiral CT [29].
  • MATERIALS AND METHODS: Hepatic helical CT was performed in 250 consecutive patients with computer-assisted bolus-tracking technology after either mechanical injection at 3 mL/sec (n = 177) or manual injection (n = 73) of 150 mL of iopamidol [30].

Gene context of Tomography, Spiral Computed

  • We describe a case of pancreatic cancer in which the spread pattern of injectate during neurolytic celiac plexus block was evaluated by three-dimensional helical computed tomography [31].
  • OBJECTIVE: To evaluate the role of multiphasic helical computed tomography (CT) in planning surgical treatment for pelvi-ureteric junction obstruction (PUJO) [32].
  • CONCLUSIONS: Low- and standard-dose spiral CT provides similar lung density data in COPD [33].
  • Correlation of VEGF with contrast enhancement on dual-phase dynamic helical CT in liver tumors: preliminary study [34].
  • BACKGROUND: The aim of this retrospective study is to assess the accuracy of single slice helical CT scan with intravenous, and rectal contrast (CTRC) in the diagnosis of acute appendicitis (AA) in patients with suspected AA, with particular analysis of the diagnostic signs [35].

Analytical, diagnostic and therapeutic context of Tomography, Spiral Computed

  • CONCLUSIONS: Perfusional sonography shows good diagnostic agreement with spiral CT in hypervascular HCC and may be proposed for the immediate vascular characterization of nodules detected at US and used as second imaging technique to confirm hypervascularity in cirrhotic nodules [36].
  • PURPOSE: To evaluate pulmonary dynamic densitometry (PDD) by means of spiral computed tomography (CT) for detection of ventilation abnormalities in obstructive airways disorders compared with dynamic xenon-133 single photon emission CT [37].
  • Staging of digestive endocrine tumours using helical computed tomography and somatostatin receptor scintigraphy [38].
  • Since rough cystine stones have been reported to be susceptible to shock wave lithotripsy, the identification of this morphology of cystine stones in the patient using attenuation values and appearance on helical CT could be valuable for planning treatment [39].
  • METHODS: Measurements of the jugular foramina were obtained from reformatted helical CT scans obtained in 12 children with complex or syndromic craniosynostosis and raised ICP (group 1) and in two control groups of children with normal ICP [40].
