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.

Comparative Study[CT-guided transthoracic needle aspiration of solitary lung lesions. Personal experience in 118 cases].
Fast-scan CT is widely and frequently used to guide fine-needle aspiration biopsy (FNAB) of questionable lung nodules. To investigate technical problems, complications, diagnostic accuracy and indications of this technique, the findings were reviewed relative to 118 patients with negative transbronchial biopsy and sputum cytology who underwent CT-guided FNAB of solitary lung lesions. Over a 25-month period, 73 men and 45 women underwent CT-guided FNAB of lung lesions. ⋯ CT allowed the lesions to be approached easily and precisely, which is useful especially in small, peripheral or hilar, nodules missed or poorly defined by radiology. To conclude, CT-guided transthoracic FNAB can be suggested as the method of choice to diagnose lung lesions which are difficult to puncture endoscopically because of size or location, and in suspected metastases. Moreover, FNAB can be used as second-line method in the lesions where endoscopic biopsy cannot be performed or whose findings are negative.

Case Reports Comparative Study[Pneumoperitoneum caused by thoracic injury].
Among the various causes of free abdominal gas, there should be included those following chest injuries. In these cases, pneumoperitoneum may develop as a consequence of different physio-pathologic mechanisms and can be associated with pneumothorax and/or pneumomediastinum and/or retropneumoperitoneum. ⋯ In this trial, the authors investigated the clinical and semiologic meaning of this finding, frequently disregarded in traumatologic literature, which was observed in 6 cases of chest injuries: 4 blunt and 2 penetrating traumas. In this condition, even though conventional radiology remains the method of choice, CT can be considered as an integrative technique of great panorama allowing small amounts of free abdominal gas and related thoracic and abdominal injuries to be demonstrated, especially in the patients in forced supine decubitus, in whom abdominal plain films can be difficult to perform.

Comparative Study[Role of magnetic resonance in the follow-up o hepatocarcinoma treated with percutaneous ethanol injection (PEI) or transarterial chemoembolization (TACE)].
The purpose of this study was to assess Magnetic Resonance Imaging (MRI) patterns of hepatocellular carcinoma (HCC) treated with percutaneous ethanol injection (PEI) or Transarterial Chemoembolization (TACE) and, consequently, the potential role of MR Imaging in the follow-up of these lesions. HCC treated with PEI. Thirty-one patients with a single small HCC lesion underwent MR Imaging at 0.5 T before and after PEI. ⋯ In the remaining 5/10 HCC lesions, persistent viable tumor portions were found at pathology. These areas corresponded to areas on hyperintensity of Gadolinium-enhanced SE T1-weighted images. Hypointensity on both SE T2-weighted and enhanced SE T1-weighted images was a characteristic pattern on long-term follow-up MR images in 21/26 unresected lesions; this finding was correlated with devascularization at angiography; the presence of hyperintense areas on SE T2 weighted and enhanced SE T1-weighted images corresponded to the persistence of hypervascular (viable) areas at angiography.
