CONTEXT: Neuroimading is increasingly being used as a non-invasive method to assess the increase in intracranial pressure (PKI). The measurement of the diameter of the optic nerve (ONSD) using MRI is well correlated with invasive PKI, but little research has been done on the ONSD measurement by CT in correlation with PKI. This study examined whether CT scanners can reliably replace MRI when measuring ONSD. There are significant differences between imaging techniques, plus in U.S. diameters less than 5.5 cm. We recommend AAAs that measure ≥5 cm at us-dollar, should be subject to prior referral to vascular and CT service. Methods: A total of 200 patients who received prospective treatment and suffered unilateral front shoulder instability were subjected to CT of both shoulders. The area of the missing Glenoid was calculated from 4 sets of CT scans (2D and 3D-CT images with or without comparison with the contralateral shoulder) with the circular method. The correspondence between the 4 measures of quantification of the bone defect was estimated using the Bland-Altman method. The agreement between the 4 measurements made in assessing the presence and nature of the defect (fracture or erosion) was analyzed with statistics.

doi.org/10.1258/ar.2011.100496 The British screening program for abdominalalortic aneurysm (AAA) refers to 5.5 cm ≥ ultrasound aneurysms in vascular services for the use of CT scans and procedures. We looked at the gap between the U.S. and CT, the impact on clinical decisions, and the extent to which CT should be used. Breath-controlled turbospin (SS-TSE) echo, T1 breath-weighted turbofeld echo (TFE), balanced rapid field echo (BFFE) and T2-weighted MultiVane sequences were performed in 1.5 T in 20 prospectively recorded patients. Two independent radiologists studied postnatal CT and MRI, which assessed the presence of cysts, hyperinflation, solid component, abnormal arteries and/or venous drain and broncho headache. Diagnostic performance of mri scans was calculated and matching results was assessed using the McNemar Bowker test. The Interobserver agreement was measured with the Kappa coefficient. The objective is to assess the extent of the adequacy between CT scans, magnetic resonance imaging (MRI) and surgical outcomes in dogs with degenerative lumbosacracic stenosis.
