Comparative Study[Computed tomography in the diagnostic approach to acute mesenteric ischemia].
Intestinal ischemia is an uncommon disorder, whose incidence is nevertheless increasing and whose mortality remains high. The major cause of its poor prognosis is represented by the diagnostic delay depending on the poor specificity and late onset of the various clinical, biohumoral and radiographic signs associated with bowel infarction. ⋯ With CT, diagnostic accuracy is fairly increased in acute mesenteric insufficiency. CT allows this condition to be detected earlier than conventional radiology and permits the early recognition, in a larger number of cases, of the patients who will benefit most from a surgical or radiologic treatment.

Review[Computed tomography in gunshot trauma. I. Ballistics elements and the mechanisms of the lesions].
The knowledge of wound ballistics and of wounding mechanisms is mandatory for the radiologist to interpret the CT findings of gunshot wounds. The severity of a bullet wound depends on the characteristics of the tissue it goes through, i.e., tissue elasticity, density, thickness of the wounded body part, the type of tissue, its specific gravity, internal cohesiveness and anatomical relationships, as well as on missile characteristics, i.e., mass, shape, fragmentation and deformation. Bullet velocity is certainly a major factor in wounding, but it is only one factor. ⋯ Bullet "yaw" is defined as the angle between the long axis of the bullet and its flight path. The yaw is directly proportional to tissue crushing and stretching: the wider the yaw, the most severe tissue crushing and stretching and, therefore, the more severe tissue damage. The basic knowledge of these concepts is of the utmost importance to understand the CT findings of gunshot wounds and can help physicians study and treat gunshot wounds.

Comparative Study[The scintigraphic prediction of residual lung function after lobectomy in patients with bronchial carcinoma].
The scintigraphic prediction of residual pulmonary function after pneumonectomy has been validated in a number of studies while scintigraphy is not standardized in case of lobectomy. This study was aimed at investigating the accuracy of the scintigraphic prediction of post-lobectomy lung function using Wernly method. ⋯ A good correlation between predicted and observed data was obtained in both the pneumonectomized group (r = 0.77 and 0.78 for CV and VEMS, respectively; p < 0.005) and the lobectomized group (r = 0.74 and 0.79 for CV and VEMS, respectively: p < 0.005). It can be concluded that the method used for the scintigraphy prediction of post-lobectomy pulmonary function is as accurate as the post-pneumonectomy method and can be used reliably in the clinical practice.
